South Monck Nature Reserve is the newest property acquired by Muskoka Conservancy. This nature reserve is over 70 acres and consists of large wetland areas and significant bird habitats. There are several species at risk that have been seen on the property as well as a large number of bird species. Additionally, it's adjacent to the Upjohn Nature Reserve, which has maintained trails as well as large wetlands.

In addition to the wetlands, the property also has representations of other habitats. There are upland hardwood and mixed forest and lower mixed and coniferous forests. Part of the wetland consists of a thicket swamp as well as a small pond. There is also a small meadow on the property, which provides suitable habitat for Bobolinks. Finally, it has a number of vernal pools, which provide great habitat for amphibian species.
