The granitic soils of Arthurs Seat retain one of the few large areas of remnant vegetation on the Mornington Peninsula. The Arthurs Seat Habitat Restoration project seeks to enhance the habitat quality of Arthurs Seat to support the unique wildlife of the area. A major threat to the site is the encroachment of environmental weeds. The project will protect several threatened species recorded in the area, including Lewin’s Rail, White Bellied Sea Eagle, Powerful Owl and Southern Brown Bandicoot.

Sheepwash Creek Catchment Landcare began work to restore Arthurs Seat in 2013 through the removal of habitat-changing weeds. Following tried and true revegetation principles, the group is working outwards from areas of highest biodiversity, having started at the headwaters of Sheepwash Creek near the OT Dam. Due to the high quality vegetation in the surrounding area, extensive regrowth of native species is already occurring, including the germination of large numbers of Rough Tree Ferns. The project is continuing to expand out from treated areas, with the aim of restoring the full expanse of bushland on the northern slopes of Arthurs Seat – the heart of the Mornington Peninsula.
