The team of staff and volunteers at the wetlands have been working towards natural habitat renewal and having two major species return is a sign that the team’s efforts are proving successful.
The Rakali (Australian water-rat) is an attractive and large aquatic mammal that resembles a small otter — several have recently been discovered on-site at the Mokoan Ponds.
This sighting is the first in the area for almost 40 years.
It is thought that water-rat numbers have declined in many places in south eastern Australia, particularly since the mid-1990s, and the sighting is evidence that conditions are improving for this species.
Similarly, Squirrel Gliders were discovered again at Winton Wetlands in late 2018, which is another first in 40 years.
While the Squirrel Glider is widespread on the east coast of Australia, it is uncommon, and staff and volunteers are ‘‘very excited’’ to have a population calling Winton Wetlands home.
In the woodlands, nest boxes have been placed at strategic locations which is one of the reasons the population of Squirrel Gliders is improving.
‘‘The discovery of Gliders points to the very strong value of corridors to allow species to recolonise the site and therefore increase the area’s biodiversity,’’ Winton Wetlands restoration scientist Lance Lloyd said.
‘‘Likewise, the improvement of habitats at the Mokoan Ponds in terms of aquatic vegetation, carp control and woody debris has meant Murray Cod can thrive.’’
Murray Cod, a native freshwater fish listed as vulnerable, numbers have declined significantly across the Murray-Darling Basin due to overfishing, river regulation, and habitat degradation.
Despite the near absence of water, Murray Cod are present in Winton’s permanent water bodies which highlights the importance of habitat improvements as a restoration process.
‘‘Having rediscovered the species at the wetlands in the past few years, we are proud to have evidence of prolific breeding and a healthy juvenile survival rate,’’ Mr Lloyd said.
