Tree Removal

Australia is home to many grasslands, rainforests, savannahs and diverse woodlands. Trees and canopies cover a significant portion of the country. Such greeneries are crucial in keeping the suburbs livable. They are vital in our surroundings. Besides, trees can be a flood-proofing tool. To learn more about trees and their role in our environment, let us go through some of the top tree statistics in Australia.

Australian Forest Areas

  1. Australia is globally recognised as the country with the seventh-largest forest area, covering 3% of the world’s total forest area.
  2. 39% or 51.8 million hectares of Australia’s forest is within the vicinity of Queensland and is the country’s largest area of forest.
  3. Australia’s Northern Territory covers 23.7 million hectares of forest, while Western Australia and New South Wales cover 21.0 million hectares and 20.4 million hectares.
  4. Eucalyptus forests cover 77% of Australia’s national forest land, while acacia forests make up 8 %. The melaleuca and rainforest form 5% and 3% of the total.
  5. Forests are typically preserved and confined to regions where the annual average rainfall exceeds 500 millimetres. 
  6. Of the 132 million hectares of native forest, 47.2 million hectares are on leasehold land, and 41.0 million hectares are on land under a private freehold title.
  7. 88.2 million hectares or 67% of the country’s native forest is under some type of private and restricted management.
  8. Consequently, 21.7 million hectares (17%) of Australia’s native forests are within formal nature conservation reserves, while 9.8 million hectares (7.4%) are in multiple-use public native forests.
  9. Australia’s 134 million hectares of forest is equivalent to 17% of the country’s land area.
  10. One hundred thirty-two million hectares or 98% of Australia’s total forest area, are considered ‘Native forests’. ‘Commercial plantations’ cover 1.95 million hectares, while the 0.47 million hectares are ‘Other forests’.

Native Trees and Canopies

  1. The country has a staggering 24,000 species of native plants and trees. Acacia, grevillea, emu bushes, and gum trees (eucalyptus) are among the most common Australian trees found in native forests.
  2. The King’s Holly from Tasmania is Australia’s oldest-known tree. It has been around for about 43,000 years.
  3. The tallest living tree in the register is a 99.8-metre gum known as the Centurion in the Arve Valley, Tasmania. It was identified and measured in 2008.
  4. A study from the University of Technology Sydney showed that the greenest capital city of Australia is Hobart, with tree canopies covering about 59% of the Tasmanian capital.
  5. Tree canopies cover 49% of Brisbane and 28% of Darwin. They make up the top three greenest cities in Australia, with Hobart as the number one.
  6. Sydney and Melbourne are in the bottom two ranks of the greenest cities, at 15% and 13%, respectively.

Deforestation & Tree Cover Loss

  1. Approximately 500,000 hectares of native woodlands and forests are destroyed across Australia every year.
  2. Due to excessive tree-clearing, an estimate of 750 million native animals in Australia will die by 2030.
  3. There are about 24 billion standard trees in Australia. These trees have a trunk diameter of 30 centimetres and stand approximately 15 metres tall.
  4. Australia has lost 62 hectares of humid primary forest from 2002 to 2021. In the same period, the country’s total humid forest area reduced by 0.49%.
  5. 2.9 % of tree cover loss in Australia occurred in areas where the dominant drivers of loss spawned deforestation.
  6. The top 2 regions, namely New South Wales and Western Australia, were responsible for 59% of all tree cover loss from 2001 to 2021.
  7. New South Wales recorded the most tree cover loss at 2.88Mha, significantly higher than the average of 970 kha.
  8. Australia is currently facing a land clearing and deforestation crisis, with an MCG-sized area of woodlands and forests bulldozed every 86 seconds.
  9. About 50% of the country’s forests and bushlands from the pre-European arrival have been permanently destroyed and cleared for other land use. Most of these areas are now regrowing vegetation, classifying them into degraded forests and bushlands.
26. As of today, only 50% of Australia’s historical forests and bushlands remain intact.
  1. Since 1750, the country has lost 27% of the total rainforest, 28% of mallee forest, 19% of open forest, and 11% of the woodland forest.
  2. In recent years, Australia’s aggressive level of land clearing has ranked the fastest among the developed countries.

Tree Removal

  1. Tree felling and related activities account for serious injuries and fatalities of workers each year. Australian data shows that about 65% of casualties occur during tree felling, 20% during lopping/trimming, and 7% during clearing/cutting trees.
  2. Most tree removals occur around major development sites rather than in undeveloped areas. Trees can be removed or bulldozed to provide land access, scaffolding, and other development purposes.

Key Takeaways

Trees are vital and invaluable. However, the tree statistics show that they often go through destructive incidents of abuse and irresponsible handling for short-term gains. Care for the trees in your property and your neighbourhood by partnering with a professional tree arborist company. A well-rounded team like Trees Down Under ensures that your trees are well-maintained and healthy. Let us take our part and be responsible for preserving the environment.

Australian Bushfire Statistics 2022

Tree Removal

Bushfire season threatens the entirety of Australia. It is an overly destructive phenomenon that can be difficult to contain once the fire has begun. Although it’s devastating, bushfires are intrinsic parts of the country’s environment. Historical and recent fires shaped and helped the natural ecosystems evolve. While naturally occurring bushfires are inevitable, studies show that mitigating their potential impacts can lessen the consequences and casualties. Let us look further into this matter and identify some important Australian bushfire statistics.

Bushfire Seasons Throughout the Year

While bushfires can occur at any time of the year, the peak bushfire period in Australia is during the dry season. However, it can vary across the country depending on the seasonal weather patterns. In southern Australia, bushfire season peaks during autumn and summer or between December to May.  For northern Australia, bushfires peak in winter and spring or during the dry season between May and October. Lastly, the central region’s bushfire season runs from August to March. The most fire-prone areas worldwide are southern New South Wales, Victoria, and Southeastern Australia. Weather conditions significantly influence the intensity, speed, size and predictability of bushfires and the extent of the danger they can bring to the community.

Most Catastrophic Bushfires in Australia

Major Australian bushfires occurred between 1967 and 2013, resulting in over 8000 injuries and 433 deaths. The fatality was about 50 per cent of all deaths from significant Australian natural disasters during that period. Over 19 million hectares burned during one of Australia’s most catastrophic “Black Summer” bushfire peak seasons from 2019 to 2020. The fire destroyed many forests and bushlands, killing more than 1.25 billion animals. New South Wales was the most affected region, with many burned areas being forest and conservation land. According to some sources, at least 80% of the Blue Mountains and 53% of the Gondwana world heritage spots were destroyed and burned. As a result, billions of animals lost their habitats and lives. Moreover, many Australians were affected by the bushfires, and at least 30 people died during such a catastrophe Households and commercial buildings were partially damaged or destroyed, pushing early insurance claims to a whopping value of 1.9 billion Australian dollars in February 2020. Bushfire in the country has worsened over the years with increasing drought areas pressure on forest recovery and resilience. A confirmed climate change-driven trend has been a tool in igniting more intense bushfires. Forest experts and managers reevaluate traditional tree recovery approaches with probable threats of future wildfires like the 2019-20 “Black Summer”. Some even wonder if restoring forests is viable.

Mitigating Bushfires in Australia

Research professionals actively assess various interventions and approaches to produce trees and plants with fire-resilient trees. However, such initiatives have a long way to go. Today, the local government has tried various ways to prevent bushfires and minimise the dangers. The bushfire management and national environment law aim to offer guidance during emergency wildfires. In the case of bushfires, suppression and containment activities are a must to protect life and property. Firefighting is an emergency action taken to stop or suppress bushfires. During the 2019-20 bushfire season, thousands of firefighters battled the blazes to mitigate such devastating incidents. Most have put off the fires in the worst-hit areas of Victoria and New South Wales (NSW). On the other hand, preventive actions are essential in reducing the severity of bushfires before they even happen. Fire prevention includes tree management activities, tree trimming and removal. If you have trees on your property or your home is close to vegetation, undertake tree management activities to keep your place safe from bushfires. When things get too tough, you can always get help from a professional tree arborist.  


Bushfires are devastating incidents that can result in loss of life, property damage, environmental destruction and economic losses. Knowing some compelling bushfire statistics helps us understand which approach to take in order to lessen the potential impacts of fires. Don’t let your home or commercial property suffer from destructive bushfires. Make sure you do your part in preventing bushfires.

Tree Removal Inspections: 5 Things You Need To Know

by Administrator 0 comments

Tree Removal

Anyone who has a tree in their yard understands its threat to their household and neighbours and passersby. Removing an old tree is the most sensible solution because there are significant risks of falling branches that could damage utility lines and pose a safety hazard. However, the tree removal process is a hazardous project in and of itself. Taking down a massive tree safely and efficiently requires access to specialised equipment and highly trained arborists. A professional team on top of your tree removal process will thoroughly inspect the tree and its immediate vicinity to determine the safest way to get rid of it. Before you head out and seek any arborist, here are five things you need to know about tree removal inspections.

Tree Removal Must Be Your Final Option

Before thinking about having a professional cut down your tree, understand that tree maintenance can improve your tree’s health and add value to your property. Trees also support the local wildlife and minimise safety risks as long as they are well-maintained. Calling a contractor with a chainsaw will most certainly recommend tree removal right off the bat. You need a certified tree arborist who knows what’s best for your tree, depending on its health and structure. In other words, arborists will recommend available alternatives to preserve your tree, which are typically more affordable than tree removal. They will inspect the tree’s health and treat underlying diseases that would restore its health without cutting it down.

Removal Contractors vs. Arborists

A tree removal's estimated cost will depend on several factors, such as equipment and labour. But if the process isn’t executed safely and efficiently, you might pay extra if the tree falls down on the wrong spot, damages your or your neighbours’ property, or harms anyone nearby. There’s more than one way to cut down trees, and risks or costs vary significantly. Specialist arborists have extensive knowledge and experience removing old trees without damaging your property or nearby trees. Remember that tree removal can be complicated or easy, depending on the tree type or location. If a contractor cuts the tree trunk right at the base, expect a fast and cheap project with drastically higher risks. As the country faces consecutive climate disasters and storms, we expect the demand for tree removal and qualified arborists to rise. But that said, be careful of contractors advertising door to door to offer cheap tree removal, as certified specialists and trained arborists don’t practice this. We highly recommend calling proven arborists who strictly abide under safety standards to help you protect your property and assets throughout the tree removal project.

Tree Removal Regulations

An enormous green old tree typically equates to longer red tape. While you technically own the trees rooted in your property, the decision to have them removed doesn’t always fall under your hands. Some states and cities can legally intervene and regulate tree removal projects. That means homeowners need to acquire inspection certifications and permits before taking down their trees. Depending on your suburb, you may need to seek approval from your homeowners’ association. A certified and time-tested arborist should assist you with all the permits and schedule a convenient hour for your tree removal project.

Stump Removal and Lumber Cutting

Your yard should be clean of any eyesore after a tree removal project. That’s why you should partner with an arborist who would get rid of the stump and any unwanted debris from your yard. In terms of the tree lumber, your arborist should give you options on whether to get rid of it with a chipper or cut it down to firewood. Feel free to call us at 0475 463 597 to discover your tree removal options and a free quote.

Hazard on Nearby Vegetation & Property

When a tree or its limb falls, it can damage the owner’s yard and the neighbour’s property. If you think your old tree poses a risk to a nearby tree, yard, or property, we recommend seeking professional help to file a request for tree removal and a certified letter. Having a letter will act as a financial safety net if the project ultimately damages your property. You can use it to proceed with your insurance claims. In a nutshell, the tree removal process should be straightforward and affordable if you have a trusted partner on your back. If you have an old and barren tree in your yard, Trees Down Under is here to respond 24/7. Call our team on 0475 463 597, and discuss your tree removal request. We’ll respond with a free estimate. We are the perfect solution to all your budget-friendly garden and landscaping needs.

Can I Trim a Council Tree?

Tree Removal

Public lands include trees that are under the restrictions of the council. You cannot simply touch or trim these council trees without a permit.  If you’re dealing with council tree issues, the first thing to do is apply for a permit to the council. You have to secure the approval, and they will verify your concern before touching the tree. The council will send their tree contractors to your site and address the issue. Many local councils around Sydney have partnered with various tree care service providers to solve council tree issues. With a single call, they will get on the job without delays and make your worries disappear.  There are many circumstances that may involve a council tree. Here are some of those and what you can do about them. 

Council Tree Blocking the Driveway

A council tree fallen due to a storm may or may not call for council service. You can cut it and remove it yourself to clear the way.  However, it would also be best to let the council know about the situation as they can be of great help. Depending on the tree contractor’s availability, they can get rid of the blockage in just a few hours.  If you’re in a hurry and don’t want to handle the job yourself, calling an emergency tree service provider is a better option. Remember to look for affordable, fast and reliable arborists for your peace of mind and convenience. 

Council Tree Overhanging in Your Property

Overhanging trees can be an obstruction to your property. You can trim a tree when it’s on private land, as long as it’s not protected. But when it stands on public land, you must always notify the council before doing anything.  The council has tree removal contractors who will do the trimming or cutting. You can refer to the local tree trimming and removal laws to be aware of the regulations before touching a council tree in Sydney. 

Applying a Permit to the Council 

In Sydney, you can apply to prune or remove a tree by filling out the forms and submitting them to the council. You will need to pay a fee for your application which may range from $30 to $150. The council will then evaluate your application and notify you within 28 days if granted. Tree contractors will do tree inspections afterwards to check the overall health status and structure of the trees.   Keep in mind that the local court may charge a fine of $5,000 to $110,000 for cutting down or removing trees on public land without a permit.

Tree Trimming and Removal Solutions in Sydney

The local government protects trees on public lands. Before you can trim, cut down, or remove council trees, you will need to secure a permit first to avoid paying fines. If the application process feels exhausting, as you may lack time due to busy schedules, a professional tree service company can help. Trees Down Under will assist you in the permit application and get on the job for you once everything is settled. You can count on our expert arborists for any emergency tree trimming or removal service in Sydney. We will answer all your queries and provide the best solutions to any tree-related issue.  Call us to book your service!

10 Tips to Effectively Reduce & Prevent Bushfires

by Administrator 0 comments

Tree Removal

Bushfires may occur due to various reasons. It can result from climate change or human error. These catastrophic phenomena put our lives, property and natural resources at risk. So, what can we do to reduce and prevent them? Although it might be difficult, taking simple but effective preventive measures is the key to minimising the severity of destructive bushfires. Here are ten tips to effectively reduce and prevent bushfires from happening. Read on to know more.

1. Adhere to Environment Laws and Regulations

Australia’s national environment law protects and preserves our surroundings and natural environment. The entire population needs to follow such regulations to keep everything safe. Many local government units have laws governing any burning. There are some restrictions to when and what to burn. We all have a significant role to play when it comes to reducing bushfire incidents across the country.

2. Pay Attention to Weather Conditions

Weather conditions like drought affect the overall flammability of any vegetation. Checking on weather updates lets you know what measures to undertake to prevent bushfires from starting on your property.  When it’s hot and windy, it’s best to refrain from doing any activities that involve fire, such as building a campfire or burning debris. 

3. Check the Risk of Bushfires in Your Area

You can check the local forecast of bushfires for fire safety alerts. If you’re in an area with a history of bushfire incidents, make sure to prevent doing activities that could cause a fire.  Many areas in Sydney are at risk of bushfires’ daily. We should be aware of this and take the right measures to keep everything safe.  

4. Keep Vehicles Off Dried Grass

When you’re off the road during a hot day, keep in mind that your exhaust temperatures can reach above 1,000 degrees.  Don’t park on dry grass to avoid sparking off a fire. 

5. Tree Pruning and Maintenance 

Pruning can significantly help you take care of your trees and prevent them from causing a bushfire. This method allows you to keep your trees healthy while clearing out huge branches that may fuel a fire.  It’s a job better left to professional arborists as they know what to do to eliminate any risk that comes with having trees overhanging buildings and power lines. 

6. Regularly Mow the Grass and Rake Up Dried Leaves

A bushfire can start at any place with vegetation. It can even start from your backyard. So, if your property is near forest and bushland, it’s essential to take preventive measures to lessen bushfire incidents Routine grass mowing and raking up dried leaves are some of the simple but effective ways to reduce the probability of starting a bushfire in your place. 

7. Dispose of Used Matches and Cigarette Butts Properly

Don’t just throw lit cigarettes outside your car when you’re on the road, especially in areas with vegetation or bushland.  These small things can spark a fire when they land on dried vegetation such as grass and leaves. You can dispose of your used cigarettes and matches in a closed container to ensure safety.  Another way is to dip them down into a cup of water before throwing them in the trash bin. 

8. Clean Your Area 

Make sure to clear away fallen leaves, twigs and other debris from your gutters and roofs. Also, keeping your outdoor combustibles to a minimum helps reduce the chance of dealing with sudden fire due to flammable substances. 

9. Don’t Use Fireworks on Areas Near Vegetation

Many of us love fireworks and sparklers. However, remember to only light up fireworks in a wide-open space without any flammable materials.  You can check your local ordinances to verify the restrictions and make the right move when using fireworks. 

10. Never Leave a Fire Unattended

If you’re doing campfires, start them in an appropriate place, away from all vegetation. When you’ve done your activities, make sure to put off the fire and never leave it unattended.  Doused it with water and smothered some dirt on it before leaving to ensure no flame was left. 


Our simple actions for bushfire prevention can make a big difference if we all work together. We shouldn’t let bushfires take a significant portion of our wildlife and environment.  Knowing the risk factors and undertaking steps such as tree care and maintenance will effectively help minimise bushfires and preserve our natural resources.   We at Trees Down Under know how destructive bushfires are. Hence, we help prevent them through our tree services in Sydney Simply call us if you need to prune or remove a tree that may fuel a bushfire. 

5 Non-Native Trees that Thrive in Sydney

by Administrator 0 comments

Tree Removal

It is a common fact that Sydney is the most populous city in Australia. Based on the latest figures, it has about 4.9 million residents. Furthermore, Sydney plays a vital role in the economy of the country. In 2018-2019, it generated an economic output of about $460 billion – about a quarter of national GDP.   As most businesses and industries settle in Sydney, residents rarely enjoy green and relaxing sceneries. But that would not be the case if you choose to plant trees in your backyard. Trees provide shade, aesthetics, fresh air, and even privacy once established. Thus, investing in them would not be a waste. Do you want to plant trees but don’t know what to choose? Cross out those common trees found in your neighbours’ lawn. With these five non-native trees that thrive in Sydney, your garden would undoubtedly be one of a kind. 

1. Japanese Maple (Acer palmatum)

As its name implies, Japanese maple originated in Japan but is also native to Korea and China. It is often part of Japanese landscape design. It has gained popularity among Sydney garden owners due to its attractive and colourful foliage, which varies from shades of green to orange, red, or purple – depending on the species type.   Japanese maple grows up to 2.5m-8m tall and wide. It grows best on partly-shaded sunlight, slightly acidic and well-drained soil, and regular watering. Once established, it can survive dry periods and destructive garden pests. Also, pruning is optional unless you want to clear its parts that become obstructions. 

2. Monterey Pine (Pinus radiata)

Monterey pine is native to the Central Coast of California and Mexico. It is an evergreen, recognised as the most popular Christmas tree in Australia. Being a fast-growing plant with a cone-shaped structure, some garden owners use it as hedges to mark their property boundary for security and privacy.  It usually reaches 12-27m tall, depending on its kind. It prefers partial to full sun and sandy or sandstone soil. Its slim and cylindrical flowers appear as pale beige or pink, while its needles are glossy dark green.  Its foliage rapidly grows, so it requires pruning, especially when dead and diseased branches are present. Moreover, it needs some tree treatments as it attracts animals and pests for shelter and food. 

3. Blue Jacaranda (Jacaranda mimosifolia)

Have you passed by on Jacaranda Street in Sydney’s North Shore? If not, you missed your chance to see the majestic and jaw-dropping rows of trees leading the highway.  Blue jacaranda is a sub-tropical tree native to south-central South America. With its fragrant and purple trumpet-shaped blossoms, Sydney residents love to have them inside their lawn space. It adds a different vibe to the usual green scenery of most gardens.  Blue jacaranda grows 7-15m tall and 4-9m wide. It prefers full sun, neutral to acidic and well-drained soil. Once it matures, tree care and maintenance seem easy as it is resistant to most pests and diseases and drought-tolerant. However, foliage debris drops often, so avoid placing them near pools or drainage unless you can clear the leaves immediately. 

4. Seven-son Flower (Heptacodium miconioides)

Native to China, the Seven-son flower is classified as a large shrub or small tree, depending on its type. Unlike most plants that start blooming in spring, it flowers in late summer, keeping your garden appealing all four seasons long.  It produces fragrant white flowers, which is a colour of purity and calmness. Once the petals drop, it exposes its pink sepals, adding great harmony in a greeny environment. It reaches between 3-9m tall and 2-5m wide. It grows best on a full or partial sun, acidic and moist soil, and regular watering.  Aside from pruning and trimming during its early stages, it does not require any particular tree treatments. Pests and diseases are not severe threats to this tree. 

5. Crepe Myrtle (Lagerstroemia indica)

It is a rising backyard tree in most Australian gardens. Even though it is native to Korea and China, crepe myrtle grows well in the southern regions. With its varying flower colours – may it be white, red, pink, or purple – it has become one of the most-sought trees. Moreover, its flower is undoubtedly one of a kind due to its very wrinkly and crinkly texture and crepe-like appearance.   Typically used as a landscape plant, it can grow between 2-9m tall and 4-8m wide. It grows best in full sun, and while it can dwell on any kind of soil, it prefers moist and well-drained sites.  Although a handful of pests can infest crepe myrtle, it is very resilient and grows undaunted by these creatures. Once established, it can be tolerant of heat and drought but constantly requires pruning to maintain its best shape and health. 


As a metro city, Sydney is becoming more and more urbanised. With the limited parks and green sceneries in the area, it is the best choice to establish trees in your garden space. They will not just bring fresh air and shade, but they will also offer aesthetics and privacy.  Planting common Australian native trees is good, but choosing non-native ones is probably better. With the featured five non-native trees that thrive in Sydney, we wish that you can pick the most suitable trees on your property.  And if you ever need an expert’s advice, Trees Down Under is just a call away.

5 Worst Tree Pests in New South Wales

by Administrator 0 comments

Tree Removal

New South Wales is Australia’s largest state economy, contributing more than $500 billion every year. Its population, which is about 8.1 million residents, consists of professionals from fields of retail trade, manufacturing, health care, and construction – to name a few.  With its economy thriving, we can expect that people keep a busy and hectic life. If you are an NSW resident, it is okay to take a breather from time to time. At night, you can relax in your garden and appreciate its beauty and breeze.   Investing in trees is a wise move. Aside from providing fresh air and shade, trees can enhance the aesthetic appeal of your outdoor space. With its foliage-rich branches and colourful flowers, passersby will undoubtedly be in awe.  But like any other living thing, you should take care of trees’ well-being and growth. Destructive garden pests can be your number one enemy once they have infested your plants and trees. They can bring sickness to your trees, which may soon lead to their death.  So for guidance, here are the five worst tree pests in New South Wales to look out for:

1. Myrtle Rust (Austropuccinia psidii)

Myrtle rust is a type of fungus that usually affects plants belonging to the Myrtaceae family. Common Myrtaceae species include Lilly pilly, eucalyptus, willow myrtle, tea tree, and paperbark. It starts as purple spots in leaves and turns yellow once the infestation ages. In extreme cases, spots enlarge and meet, causing leaves to twist and deform.  NSW Experts detected the increase of myrtle rust in 2010, affecting bushland reserves, property gardens, and even parks and street plantings. It spreads by wind, animals, insects, water, and contaminated garden tools. Now, it has reached other states such as Victoria, Queensland, and Tasmania.   

How to Manage Myrtle Rust?

Follow these steps to contain the spread of myrtle rust:
  • Familiarise the signs of infestation of myrtle rust. 
  • If detected, keep other plants away from the affected area. 
  • Always disinfect cutting tools and garden equipment before and after use. 
  • Apply fungicide to kill spores. 
  • Prune infected parts or prepare to fell the tree

2. Fall Armyworm (Spodoptera frugiperda)

Fall armyworm is a newly detected insect pest in NSW, which comes from Queensland. The larvae stage of the moth is usually light green to brown with a darker head capsule. It grows from 3 to 4 centimetres and takes 23-27 days to complete its life cycle.  Like caterpillars, the fall armyworm larvae munch leaves, creating holes and shreds to plants and trees. Too much foliage loss can make trees susceptible to stunting or sunscald Moreover, a single moth lays about 100-200 eggs, so expect heavy infestation once they hatch and develop into larvae. 

How to Manage Fall Armyworm?

Follow these steps to contain the spread of fall armyworm:
  • Check out trees for insect eggs and remove them when detected.
  • Control weeds to minimise pest hosts.
  • If you want, purchase insect traps to prevent moths from laying eggs.
  • Release beneficial insects – such as Trichogramma wasps, lacewing, ladybugs and minute pirate bugs – to feed on eggs and larvae.

3. Yellow Crazy Ant (Anoplolepis gracilipes)

Based on the Global Invasive Species Database, the yellow crazy ant belongs to the top 100 of the world’s worst invasive species. In 2018, NSW authorities detected its presence in Lismore CBD and Terania Creek North of Lismore. Its ‘crazy name means that it moves frantically and changes direction frequently.  Yellow crazy ant has about 4mm long golden-brown body and a darker brown abdomen. Its legs are relatively longer than other ant species. Instead of biting, it releases formic acid as a defence mechanism. The ideal nesting grounds for this insect are woody debris, tree bases, and leaf litters. It feeds on seeds, fruits, worms, and even larger animals such as frogs and birds as long as its colony attacks in groups. Moreover, it also protects other garden pests such as aphids and scales from beetles in exchange for nectar or honeydew. 

How to Manage Yellow Crazy Ant?

  • Inspect tree bases and garden debris of unusual ants or nests.
  • If possible, use a broad-spectrum insecticide like Fipronil.
  • Discard green waste appropriately.  
  • Call professional gardeners whenever in doubt.

4. Pampas Grass (Cortaderia selloana)

Pampas grass is a common weed mostly found in Tasmania, NSW. Before being classified as a noxious weed, garden owners used it as windbreakers or soil stabilisers. But since it spreads quickly, it has become a threat to parks, roadsides, and even residential gardens. It is a perennial plant that can grow up to 4m in height. In general, it forms large clumps of lush, grass-like foliage and brownish-white feathery plumes. Once established, it is highly competitive for water and nutrients, restricting the growth of nearby trees. Furthermore, it is a fire hazard and attracts pests or nuisance animals that spread tree and plant diseases.   

How to Manage Pampas Grass?

  • In small infestations, plant grubbing can prevent further weed growth. 
  • Apply herbicides but remember to follow NSW regulations. 
  • Hire a local garden maintenance provider like Trees Down Under.

5. Giant Willow Aphid (Tuberolachnus salignus)

The giant willow aphid is an established plant pest in NSW that clusters in branches of willow trees. It is a mid to dark-brown insect, known for its row of black spots in its abdomen. Adult species grow about 5-6mm long with a relatively short antenna, just half the body length.  As mentioned, its colony usually crowds branches of willow trees. It sucks saps from the host and releases sweet honeydew, which attracts other insects and pests. Signs of infestation include black sooty mould on twigs and deformed leaves. Both honeydew and sooty moulds interfere with photosynthesis, impeding the trees’ growth and health. 

How to Manage Giant Willow Aphid?

  • Once present, use water pressure to knock them off from the branches.

5 Australian Organisation that Help Prevent Bushfires

Tree Removal

The scale of Australian bushfires has shocked people around the world. Bushfire is a catastrophic natural disaster that can destroy lives and properties. 

The latest and most destructive bushfires recorded in the country happened from 2019 to 2020. It has resulted in the loss of over 30 lives, destroyed around 3,000 homes, and affected nearly 3 billion animals.

Many organisations came to help put the fire out and support the victims. Both government and non-government groups are working together to lessen the impacts and prevent bushfires from destroying more and more lives and habitats.

Bushfire Help

Bushfire Help builds a connection between people, businesses, and various organisations to fulfil the same goal of minimising bushfire impact in Australia.

This organisation gathers initiative to become the largest help database in the country that can respond quickly to natural disasters like bushfires. Moreover, they build awareness by providing people with the latest bushfire issues and facts.

You can donate goods and money or volunteer to various organisations through Bushfire Help. They can help you play a significant role in preventing bushfires across the country.

WWF Australia

Australia’s World Wildlife Fund for Nature strives to conserve biodiversity and let people live in harmony with nature.

The organisation focuses on giving emergency support by rescuing and caring for fire-affected wildlife. They also take part in the recovery and future-proofing of the country to be ready for the fire seasons ahead.

WWF’s mission is to halt the natural environment’s degradation by protecting and restoring natural habitats affected by bushfires and other calamities.


CSIRO is a government entity operating under the Science and Industry Research Act 1949. They are Australia’s trusted advisor on fire management, prediction and recovery, solving the country’s greatest challenges through technology and innovation.

After the devastating 2019-20 bushfire season, the government called on CSIRO for assistance. They welcome the role of delivering practical resilience actions relating to climate change and bushfires.

The agency has state of the art facilities and frameworks to understand, manage and predict fires under future climates. They train all state agencies on fire prediction and behaviour to establish effective strategies in reducing the severity of impact.

NSW Rural Fire Service

During a bushfire emergency, the first ones to call on are the firefighters. There are various firefighter organisations in the country, including the New South Wales Rural Fire Service.

The NSW Rural Fire Service has over 72,000 volunteers, making up 2,000 brigades across the state. They claim to be the world’s largest volunteer firefighting organisation, with volunteers coming from different states.

This multitude of unpaid volunteers put their lives and jobs on hold to tackle the blazes and save wildlife.

One Tree Planted 

This non-profit organisation in Australia is on a mission to help the environment by planting trees. Australia’s forests require continuous care and management to improve tree health and protect wildlife.

This simple action will help reduce the risk of destructive bushfires in the future. One Tree Planted works with environmental organisations and local landowners to keep Australian bushlands and forests healthy and safe.

They help local groups establish and plant the right kind of trees for a specific area as trees may serve different purposes.

On top of that, they undertake fire-damaged land recovery and habitat restoration for native species such as koalas, sugar gliders, and echidnas.


Preventive measures are the key to minimising bushfire impacts. That’s why organisations such as CSIRO, WWF and One Tree Planted work to conserve and protect diversity.

On the other hand, Bushfire Help and NSW Rural Fire Service take action during bushfire emergencies to put the fire out and save lives.

All organisations with the same goal can take part in preventing bushfires across the country. We at Trees Down Under carry out our role in protecting trees and greeneries through our professional tree services in Sydney.

With all of us working together, the country can make a big difference and conserve our environment from catastrophic bushfires.

Bushfire Risk & Tree Management in Sydney

by Administrator 0 comments

Tree Removal

Bushfire season brings a significant threat to Australians, especially to those living in rural areas. It is overly destructive and can be difficult to contain once the fire has started.

From 2019 to 2020, the country has experienced the most catastrophic bushfires, with up to 19 million hectares burnt. A large portion of the affected area was forest and bushland, destroying habitats and killing over 1.25 billion animals.

When it comes to bushfire risk and tree management in Sydney, acting early and continuously is the key to effectiveness. As such, we need to be aware of the dangers and the right strategies to mitigate the fire severity before it happens.

Bushfire Season’s High-Risk Trees

Many factors can affect trees’ overall condition. High-risk trees that may spread fires are often those with health issues and structural damage. However, neglected and overgrown trees can also be dangerous as they provide excessive fuel for a fire. 

Moreover, imbalanced trees can add fuel and help the fire spread quickly, burning more and more trees. While it’s obvious that large mature trees bring the biggest threat during a bushfire, the branches can also put your safety at stake

If you’ve noticed dangerous trees on your site, it’s best to have an expert arborist check them and determine what procedure to undertake for risk elimination or reduction. 

The experts will tell you whether you need tactical lopping and pruning or complete tree removal to ensure safety from high-risk trees. 

Preventing Bushfire from Starting in Your Property

Rural areas in Sydney are typically abundant with trees and greeneries. If you’re in the countryside, you probably have various trees in and around your property. 

However, trees are primarily the cause of bushfires. Hence, it’s essential to know how to keep your trees safe and prevent a bushfire from starting within your property. 

Bushfire and Tree Management Activities

There are two categories of bushfire and tree management activities. These are firefighting and fire prevention.

During a bushfire emergency, protecting life and property is always the major concern. Firefighting refers to the immediate responses taken to manage and prevent bushfires from harming life and property.

On the other hand, fire prevention involves actions that prevent or lower fire severity risk before it actually happens. Preparing for future fire seasons includes tree risk assessment procedures. These measures allow early identification of tree issues to minimise potential bushfire threats.

Certified arborists best handle a proactive search for any bushfire risk in your property. They can devise and apply risk mitigation techniques to significantly reduce the hazards of vicious fires caused by your trees.

The national environment law does not prohibit any required actions from suppressing bushfires, nor does it control the procedures taken to fight fires.

However, firefighting and fire prevention activities with significant impacts on nationally protected matters are subject to compliance actions. You might also need federal approval before undertaking such responses.

While you’re at it, know that some activities might be exempt from the regulation of national environment law. Your trusted arborist in Sydney will help you understand all of these things and keep your trees safe.

Tree Trimming for Power Line Clearance

Neglected trees can overgrow with thick and long branches obstructing power lines. This situation poses a high risk of starting a fire and needs immediate action. 

You can clear power line obstructions by trimming or pruning your trees regularly. Ensure that the branches don’t go near electric cables as they can interrupt connection and spark a fire. 

Complete Tree Removal

Another best way to reduce the potential of starting a bushfire in your property is by removing high-risk trees. Trees will eventually deteriorate, and you might need to remove them in order to maintain your site’s overall safety. 

Don’t let yourself worry about having trees that may start a bushfire at any moment. Ask your trusted arborist to assess and remove your trees when necessary.


Bushfires are extremely dangerous which could lead to life and property destruction. No one would want to see a bushfire starting within their property.

Hence, taking proactive measures to implement effective bushfire risk and tree management strategies is essential for your trees and property’s overall safety. 

With the help of professional arborists from Trees Down Under, you can take care of your trees and mitigate the risk of bushfire severity. 

If things get too tough, just give our team a call anytime, and we will extend a helping hand to you at any time. 

4 Trees That Increase Property Value in Sydney

by Administrator 0 comments

Tree Removal

In 2019, Sydney Inner West Council had a new regulation, which states “residents will no longer need to seek council approval to prune or remove trees within three metres of an existing home structure.” 

But before getting those shears and trimming equipment, consider why remove your trees in the first place when these are our natural defence against pollution? Also, aside from providing shade and fresh oxygen, trees can increase your property value. 

Based on AECOM’s study that focused on three Sydney suburbs, a 10% rise in street tree canopy can increase property values by $50,000 on average. Moreover, it can reduce energy bills by up to $400 every year. 

So, it is wise to start investing in trees now and reap their benefits in the future. Here are some of the trees that can increase your property value in Sydney:

Frangipani (Plumeria)

frangipani tropical flowers

Most species of frangipani are native to tropical regions and vary as shrubs or small trees. With their fragrant and eye-catching flowers and large-leaved foliage, garden owners love to have them in their outdoor space. Depending on the type, it blooms white, yellow, pink, or red blossoms during spring throughout fall. 

Small trees of frangipani can grow up to 4-8m tall and wide. They thrive best in full sun and well-drained soil. They require regular watering, but you need to reduce the volume during winter to prevent root rotting. 

Moreover, they are susceptible to garden pests such as frangipani caterpillars, white scale insects, whiteflies, and mealybugs. These pests usually feed on the trees’ foliage, leaving them vulnerable to sunscald or stunting.  

Red Maple (Acer rubrum)

Red maple tree

As its name implies, red maple blooms majestic red foliage but sometimes appears as orange or yellow. Considered as a tree that requires less maintenance, busy Sydney garden enthusiasts are planting it for aesthetic and hedging purposes

At maturity, it grows from 12-20m tall and 9-15m wide. It prefers partial to full sun and adaptable sandy or clay soil. Once established, it can withstand both dry and moist conditions but needs constant deep watering

There are no severe disease or pest threats for red maple, but it is vulnerable to aphids, borers, and scale. Also, pruning is rarely necessary unless very narrow angles between trunks and branches are evident. Prune at the end of the summer or in autumn to avoid sap bleeds when pruned early in the growing season.  

Sweetbay Magnolia (Magnolia virginiana)


Magnolias are classic trees among Sydney residents, but one particular variant captivates the hearts of garden owners. Sweetbay magnolia trees bloom creamy white flowers with a sweet and lemon-like fragrance. Compared to other magnolias, this charming tree produces less mess as it is semi-evergreen.  

It grows up to 15m tall in warmer areas but limited to 9m in colder regions. It requires a part to full sun and slightly acidic medium-moist to wet soil. Also, it needs regular watering as it cannot survive dry and arid conditions.  

Moreover, it is vulnerable to leaf spot disease caused by bacteria or fungi. Symptoms include circular spots with black outlines and rotting centres. Also, it doesn’t thrive well in severe winters. So you should conduct organic mulching and constant irrigation to prevent the soil from drying out.  

Mango Tree (Mangifera indica)


Aside from aesthetics, shade, and privacy, fruit trees also generate delicious products for you to consume. And you don’t need to go too far because a mango tree would undoubtedly satisfy your cravings. 

Mango trees grow up to 30-40m tall and have a crown radius of 10-15m. Although it can thrive in almost all kinds of soil, it develops best in well-drained soil, especially in regions with a colder climate. Also, it prefers full sun to produce the best quality of fruits.  

Like any other fruit tree, a mango tree needs constant care and treatment. In irrigation, the water should reach its long taproot. Meanwhile, pruning is essential to prevent fungi infestation and remove diseased branches.   


Trees have a handful of benefits once established in your garden. They provide shade, privacy and enhance the overall aesthetic of your outdoor space. But most importantly, they increase your property’s value in Sydney, which can be favourable for you in the future. 

Planting trees might be easy, but keeping them healthy is another thing. Luckily, Trees Down Under is available in Sydney for professional and excellent garden services.
