How climate change is impacting Moreland
The impacts of human-caused climate change are already being felt in Moreland, as well as across Australia. Hotter average temperatures and more extreme weather is already affecting local people, plants, and animals. These impacts will worsen if we do not stop the carbon pollution causing climate change.
Every action to reduce carbon pollution makes a difference.
You can see what actions Council is taking on our Our Sustainability Story page. You can also learn what actions you can take on our How you can take action on climate change page.
Climate change does not affect everyone equally
People suffering from social inequality feel the effects of climate change more than others. Causes of such inequality include poverty, discrimination, health vulnerabilities and trauma.
Some of the most affected groups include:
- Indigenous people
- People living with a disability
- People experiencing homelessness, economic hardship and isolation
Our commitment is to providing strong leadership on climate action. By working together we can reduce these impacts and protect all of our community as well as our planet.
Changes we are seeing in Moreland
The following weather impacts are affecting Moreland.
- We are facing increasing temperatures in Moreland. This includes higher daily top temperatures, more days above 35°C, and more heatwaves. For example, at the moment we get 8.3 days a year above 35°C, but by 2050 research says we can expect 21 days a year over 35°C.
- There will be more extreme rain events that damage buildings and other infrastructure. For example, in 2018 Melbourne experienced a 1 in 1000 year rain event. This caused flash flooding, halted train lines, and caused many power outages.
- Rainfall in winter and spring will decrease. By 2050 research shows there will be 20% less rainfall during our spring season.
- There will be more frequent and more intense bushfires. By 2050, research shows that fire days will increase by 42% in Melbourne. This will contribute to poorer air quality. In January 2020, Melbourne’s air quality was the worst in the world due to smoke from a catastrophic bushfire season.
This information comes from research conducted by the Victorian Government and CSIRO. You can see this research in the following places:
- on the Victorian Department of Environment, Land, Water and Planning (DELWP) website
- on the CSIRO website
Taking urgent steps like reducing emissions and our environmental impact can make an impact on these changes.
How will this affect us?
The changes we are seeing in Moreland will both affect us and our environment. Below are some of the ways that Moreland will feel the effects of these changes.
Our health is suffering
Everyone in Moreland will feel the health effects of climate change. Our most vulnerable community members will feel these effects the most.
- Major weather events can cause injuries, illnesses and death.
- There is a projected increase in respiratory disease cases. This can come from increased air pollution or allergens. It can also come from changes in pollen levels.
- There are many mental health impacts of climate change. This includes post-traumatic stress after weather events. There are also rising levels of anxiety and depression at the idea of future changes to our world.
Our plants and animals are in decline
Many of our local plants and animals cannot adapt to the changes in their environment. This will cause their population levels to fall or the loss of some species. Groundwater-dependent plants and animals will be most affected.
- Drought and heat stress have sped up the decline of Melbourne’s tree population. Keeping our trees healthy is a necessary way to reduce the Urban Heat Island Effect. You can find out more about this in the How we are addressing the urban heat island effect (UHIE) section on this page below.
- The populations of animal and plants that adapt to warm environments are going up. At the same time the populations of those that adapt to cool environments are going down. These changes reduce biodiversity and disrupt food chains.
We have less food security
- The food production from the food sources that Moreland relies on will reduce. This is because of rising temperatures, less rain, and more extreme weather events.
- There will be less regional and national food surpluses. We are likely to experience food deficits instead.
Our infrastructure is strained
- Transport like trams and trains will need to stop running when there is extreme weather.
- Heat waves increase the demand on our power systems. This is because more people are using air conditioners, which also increases emissions.
Built up areas trap heat in a way that is different to rural areas. This is called the urban heat island effect (UHIE). It is caused by there being a lot of activity in the one area. It is also caused by the dense, dark and solid surfaces in built up environments which absorb and retain heat.
Moreland is an area with a lot of activity, and with many built up areas. UHIE is an issue we need to address, as our aging population and climate change make us vulnerable to extreme heat.
In 2016 we developed our Urban Heat Island Effect Action Plan. This plan was made through consulting with the community and industry experts, including the University of Melbourne and Monash University. It is our first step in our long term commitment to responding to the UHIE.
The goal of the action plan is to help reduce the impacts and prepare for a hotter future. It includes strategies to be put in place across Moreland that will reduce overall temperatures. It also covers projects targeting specific locations. These steps will create benefits for those living in Moreland such as lower energy costs, better air quality and less health risks.
In 2017 this plan won the Premier’s Sustainability Award (Government Category).

Reducing the urban heat island effect
The following are some of the current steps we are taking to reduce the urban heat island effect (UHIE).
Researching and mapping
We want to get a better understanding of the impacts of heat across Moreland. We have been researching this using techniques such as heat and vulnerability mapping. This has helped us to identify the hottest areas in the city and where we should take action.
Expanding tree cover
We have committed to planting 5,000 trees each year, and to protecting our current trees. Research shows that a 10% increase in tree cover can lower temperatures by one degree. We also want to create green spaces in new developments and prioritise tree planting in areas vulnerable to UHIE. You can learn more about the plans we have to increase tree cover on our Trees page.
Conserving water will make sure that hot summers don't kill our trees and green spaces. We have an Integrated Water Management Plan for this called Watermap 2020, which you can learn about on our Water page. It covers the projects needed to improve the quality of our stormwater. It will also improve water conservation and improve the health of our waterways.
Designing sustainable buildings
All new buildings in Moreland have to meet sustainable design standards. When we plan a new Council building, we need to follow our Sustainable Buildings Policy (PDF). Private developers also need to meet sustainable design standards. Their plans have to fulfill our sustainable design in the planning process requirements. These requirements are necessary for all private development plans. You can find out more about these policies on our Sustainable Design page.
Creating strategic transport initiatives
We want to make our transport options more attractive and environmentally friendly. One of the ways we are doing this is planting trees along shared pathways. This is an effort to make walking or cycling more comfortable.
We are also advocating to reduce traffic on our major roads, and our free electric charging points promote the use of electric vehicles. We are also exploring the use of cool road materials in some areas to reflect rather than retain heat.
Creating opportunities for collaboration and advocacy
We need collaboration and effort from the all of our community to make our city more livable. We have committed to encouraging our community to take action on urban heat. This includes consulting with community members, and providing ways they can take action. You can find out how you can take individual action against climate change on our Zero Carbon Moreland website.
White Ibis at Coburg Lake
The Australian White Ibis is a protected native bird species that is known for taking up habitat in lakes across Australia.
Many users of Coburg Lake have noticed an increase in smell, noise and aggressive behaviour from the White Ibis colony.
- Many users of Coburg Lake have noticed an increase in smell, noise and aggressive behaviour from the White Ibis colony. There are some reports that the Ibis have been aggressive to other bird species and concern they may become aggressive towards people.
- Bird surveys by the Friends of Merri Creek have indicated native species of birds are declining as a result of the Ibis population. Particularly affected are aquatic species such as Pacific Black Ducks and Black Swans which have reduced dramatically.
- Numbers of Pacific Black Ducks have reduced from 60-80 per survey prior to the arrival of Ibis, to 5-20 since 2018. Black Swans have been recorded nesting in the lake for several years but were observed in 2020 being shielded from their nest by Ibis. No Black Swans were observed in spring 2020 surveys.
- Vegetation on the island and some vegetation around the lake is in decline as a result of the Ibis and much of the ground storey has become denuded. Some of the trees which are favoured by the birds (such as the Canary Island Date Palms) contribute to the Reserve’s heritage significance.
- With the roosting areas concentrated around Coburg Lake, the high nutrient content of excreta from the birds is likely to impact water quality, with increased evidence of algal growth during the summer of 2020.
Council has sought advice and developed a list of strategies that work to reduce the impact of White Ibis at Coburg Lake, in a sensitive manner that considers animal welfare, environmental and public safety and awareness concerns.
Ibis prefer to nest in and around certain vegetation types. Canary Island Date Palms are particularly preferred and are usually characteristic of the landscape where Ibis problems occur.
Some Councils have trialled palm trimming, removing dead and horizontal growing fronds, with some success. It was found to reduce the number of nests, however, Ibis then tended to nest in other palms or trees in the park or adjoining properties.
Egg and Nest Removal: Nest and egg removal have been described as effective means to manage increasing numbers of White Ibis in growing colonies.
As Ibis are a protected species, any activity that has potential to impact on the species must only be undertaken under an Authority to Control Wildlife permit issued by the Department of Environment, Land, Water & Planning.
Creating disturbances, particularly at dusk, has been shown to have some effect on roosting Ibis.
This could be through shining spotlights, laser lights, cracking whips (or other loud noises) or distress calls which may disperse the birds. The use of sprinklers has also been discussed but its effectiveness has not been trialled.
Council has engaged a contractor to undertake egg removal and nest dispersal activity (with permission from DELWP) to reduce breeding this season at Coburg Lake.
This activity is expected to be carried out in early 2022.
Vegetation management works to reduce future roosting will be undertaken after the breeding season.
