Biodiversity in Marion

What is biodiversity?

Biodiversity is the incredible variety of life on our planet. It includes everything from tiny microorganisms to the animals and plants we see every day. Biodiversity around the City of Marion helps regulate our climate, clean our air and water, provides us with food, medicine, materials and supports our physical, mental and emotional wellbeing.

The City of Marion has many special places like the Sturt River, Warriparinga Wetlands, Oaklands Wetlands, Coastal Walking Trail which support amazing plants and animals. These areas are sanctuaries, each playing a unique role in maintaining the health and balance of our local ecosystems.

Biodiversity Plan 2024-2029

The City of Marion Biodiversity Plan 2024-2029 will provide the overarching framework to assist management, enhancement and protection of natural areas and biodiversity for the next 5 years.

The plan addresses the need for consideration of biodiversity within the context of council’s management and operations by identifying values and issues and presenting strategies and actions that can be undertaken.

Protecting the natural environment and improving connection with nature are key elements of the City of Marion Community Vision; 'A liveable, sustainable community.'

Council has committed to deliver this Biodiversity Plan as a priority in the City of Marion Business Plan 2023–2027 in response to feedback from our community identifying improved open spaces and environments as a top priority for the next 4 years.
