Biodiversity is most simply defined as the variety of life on earth. All living things interact with one another and impacts to one species are usually felt by another. For example, the loss of small, insect-feeding birds in suburbia is known to result in an increase in problem insects like termites.
The City of Canada Bay is committed to protecting and enhancing biodiversity so that our nature and our way of life are preserved.
Despite the small size of our natural environment, the City of Canada Bay remains home to a diverse range of native plants (flora) and animals (fauna). You can see a chronological list of studies into our local flora and fauna by following these links:
Our recent 2023-24 Flora and Fauna Monitoring Study found several important threatened species in the City of Canada Bay, including the three endangered ecological communities listed below and nine threatened local or migratory fauna species:
Importantly, Latham's Snipe is a migratory species which breeds in Japan and Russia and only visits Australia from February to July. Another migratory species observed in the City of Canada Bay was the Bar-tailed Godwit, which similarly breeds in the northern hemisphere and winters along the east coast of Australia.
The following three threatened or endangered ecological communities were also observed in the LGA and their condition rated using the Biodiversity Assessment (BAM) Method:
City of Canada Bay launched the Backyards for Biodiversity program to support our community in creating habitat stepping stones, or refuges, for animals in residential and school gardens. By getting involved in wildlife gardening, you can help improve biodiversity in our area. The program includes:

Native animals are protected in NSW under the Biodiversity Conservation Act 2016. It is an offence to harm, kill or remove native animals, including their nests or eggs unless you hold a licence. This includes Magpies (Gymnorhina tibicen), Australian White Ibises (Threskiornis molucca), and Brush-turkeys (Alectura lathami) and their mounds. It is difficult to tell if a brush turkey mound is active or inactive, so it's always best to not disturb it and contact Council by calling 9911 6555.
If you witness someone harming a native animal, Council recommends that you do not confront them, but record the behaviour if possible, and immediately make a report to the NSW Department of Planning and Environment by calling 1300 361 967 or emailing info@environment.nsw.gov.au
If you see an injured or sick native animal, Council recommends that you contact WIRES as soon as possible by calling 1300 094 737. The trained responders at WIRES can guide you on how to manage the wildlife injury.
Help keep our wildlife wild and safe by not feeding them. Many people enjoy feeding birds and animals but this may result in future problems for animals and the community. Here are some reasons why you should not be feeding wildlife:

Since the 2000s, there has been an increased number of large native birds and flying-foxes (sometimes called fruit bats) in our local area. These include the Australian White Ibis, Brush-turkey, Sulphur-crested Cockatoo, Grey-headed Flying-fox, plus several native birds known for swooping behaviours such as the Noisy Miner and Australian Magpie.
Local governments and education institutions want to better understand the movements and behaviours of these animals. You can help by downloading the Big City Birds app and recording sightings of them and their nests or roosting camps.
There are several species of native bird which are known to swoop passers-by for a variety of reasons. Some of these birds, like the Australian magpie, do so only occasionally to protect their young, whereas other birds, like the Noisy Miner, are naturally aggressive and display swooping behaviour for territorial reasons.
The following information will help you better understand our native swooping birds, as well as give tips on how to avoid being swooped.
The Australian Magpie is a common resident of suburban parks and gardens of Sydney. They are a native species protected under the NSW Biodiversity and Conservation Act 2016 and it is an offence to harm them or their nests.
Most magpies are friendly and social, with young magpies known to approach people out of curiosity or sometimes hunger. If this happens, ensure you don't feed them, as feeding wildlife has many unintended negative consequences such as encouraging rats and making wild animals dependent on humans for survival.
Between late winter and early summer, some magpies can swoop people. They do this if they perceive that the person is a threat to their child, often choosing to swoop bicycle or scooter riders if they perceive their shiny, brightly coloured helmets to be alarming and threatening. There are several actions that can be taken to reduce the likelihood of being swooped by a magpie.
If you witness a swooping magpie, please notify Council by calling 9911 6555 or emailing council@canadabay.nsw.gov.au.
Noisy Miners are a native honeyeater species which has been found in increasing volumes throughout suburban Sydney. Originally, they inhabited regional areas in western Sydney and west of the Blue Mountains, where their ideal habitat of open grassland with tall canopy trees was naturally found. With increased clearing of dense native vegetation, Noisy Miners began expanding in urban areas. For example, a 1983 Concord Municipal Council fauna study recorded Noisy Miners in small numbers in many of our local parks including Queen Elizabeth II Park.
Noisy Mners are especially known for their aggressive behaviour, so much so that in 2014 "Aggressive exclusion of birds from potential woodland and forest habitat by over-abundant noisy miners" was listed by the Commonwealth Government as a Key Threatening Process. When open woodland habitat suits them, they have been proven to directly cause exclusion of many smaller native birds, including threatened species.
It is difficult to prevent the presence of Noisy Miners, as they are a native species and are high in number. We can, however, design and plant our gardens and public spaces to be more favourable to other bird species using the following tips. Read our Backyards for Biodiversity guide for more detailed tips.
The City of Canada Bay does not contain a roosting camp of flying-foxes, or fruit bats as they are sometimes known, however we are lucky enough to be visited by flying-foxes at dusk and night time when they feed on flowering and fruiting trees.
The most common species of flying-fox found in Canada Bay is the Grey-headed Flying-fox, which is native to the east coast and classified as 'Vulnerable' by the NSW Government, being threatened with extinction by habitat loss and a warming climate. The species is nocturnal and roosts together in camps during the day. Temperatures hotter than 40°C can cause them to fall from trees and die from heat-stress during the day. If you do you see flying-foxes on the ground in distress, please do not touch them but contact WIRES on 13 000 WIRES.
Flying-foxes are important pollinators of our plants and crops. Unlike other pollinators such as bees and birds, flying-foxes can transport pollen over vast distances and can disperse larger seeds. This makes them vital for many of our native plants and important for the longevity of many fruit trees and vines.
You have likely noticed them arriving in the City of Canada Bay at dusk when it gets cooler, looking for flowering and fruiting trees to settle and feed in. They are social creatures and often chatter amongst themselves as they feed.
Land clearing, climate change and bushfires are driving many flying-foxes to relocate to urban areas, which can put them into conflict with humans.
Most impacts of Flying-foxes are social, such as the smell and appearance of droppings on footpaths or cars.
There are minimal health impacts from flying-foxes, such as contracting Australian Bat Lyssavirus (ABLV). However, only around 1% of the wild Grey-headed Flying-fox population is known to carry ABLV and the risk of contracting any disease directly from a flying-fox or their droppings is minimal provided no direct handling occurs.
NSW Health advises that there is no risk to the public from working, playing, or residing near flying-foxes, or from contact with their droppings or urine. The only risk to members of the public is from direct contact with an infected animal, via a bite or scratch. It is important to note that there have been no recorded instances of a human contracting a virus from flying-fox droppings or urine, and that the only instances of ABLV have affected unvaccinated wildlife carers directly scratched or bitten.
As with any wild animal, please do not touch any injured flying-foxes and instead contact WIRES on 13 000 WIRES

Flying-foxes will only visit trees when they are flowering or producing fruit, so if you notice them in your trees, be assured they won't be there for long. While they are visiting your property to feed, you can follow these tips to reduce their impact:
For more information about flying-foxes, you can visit the NSW Government's Flying-fox page, or contact Council's Sustainability team by calling 9911 6555 or emailing environment@canadabay.nsw.gov.au.
Originally native to inland areas, the Australian White Ibis began emigrating to coastal areas from the 1970s and more prominently in the 2000s due to ongoing droughts and lack of water flows from upstream agriculture in the Murray Darling Basin. In suburban Sydney, they have found abundant food sources and sites for suitable nesting and breeding, often preferring artificial ponds in parks and exotic palm trees to nest in.
Ibises can be disruptive, rummaging through rubbish and leaving excess waste from droppings. So what can you do to help manage them? To help local government and scientists better understand the Ibises, you can record their sightings on the Big City Birds app. Other things you can do to minimise their impact include:
There are three threatened ecological communities or plant community types within the City of Canada Bay local government area, as well as several threatened individual plants...
