Managing native animals
Wildlife populations are dynamic. They vary naturally in distribution in response to a variety of factors such as climate, food availability and predation.
In parks, animals are often confined to limited areas that are bound by highly modified landscapes. Populations of native species have the potential to grow beyond sustainable levels. As population densities increase, overgrazing, over-browsing or trampling can result in:
- Habitat degradation and loss of flora
- Negative impacts on other native species dependant on those habitats
- Mass starvation of the population as their source of food is completely consumed.
Management and monitoring
In some cases, a native animal population may need to be actively managed to protect biodiversity and reduce the risk of large-scale population starvation.
Native animals are managed only when a particular population is:
- Threatening the survival of rare or threatened species or communities
- A major contributor to serious environmental damage or long-term degradation of habitat
- A major factor preventing habitat recovery
- Suffering from malnutrition or disease as a result of overcrowding and an inability to disperse from an artificially confined area.
Parks Victoria uses its Adaptive Management Framework to assess and plan programs to manage overabundant native animals. This risk-based approach allows us to manage the greatest risks to the highest environmental values.
Management programs are monitored regularly to determine sustainable population targets and evaluate how effective the program is.

The Yarra River is tidal and it’s not uncommon to see a dolphin or a seal in both the Yarra or Maribyrnong Rivers. Rangers noticed the seal was fishing for food and seemed quite content and, as of midday, reported that the seal was heading towards the city and is likely to be heading back toward the bay. Now seal here: playful marine mammal journeys 14km from Port Phillip Bay to Yarra Riverwww.theage.com.auA seal has swum all the way along the Yarra River from Port Phillip Bay, playing and catching two big fish before ending up in South Yarra.View post | Mon, 28 Jul 2014 14.49
