Commanda Creek Conservation Reserve consists of 1,657 hectares of Crown land, located about 12 kilometres west of the Village of South River. Roughly the eastern half of the site is located in the Township of Machar, and the western half in the unincorporated area of Lount Township, in the Territorial District of Parry Sound. It is surrounded almost entirely by privately owned lands, which are not part of this conservation reserve.
Commanda Creek Conservation Reserve is an area of heavily forested rolling hills, small lakes and creeks interspersed with wetlands. North trending Commanda Creek traverses the entire length of the conservation reserve near its western boundary.
This site was identified during the Ontario’s Living Legacy planning process as containing a diversity of landform and vegetation features, including glacial deposits of sand and gravel overlaying bedrock, rolling hills, bare rock knobs and extensive wetlands. The area has significant stands of eastern hemlock (Tsuga canadensis) and black spruce (Picea mariana). There are two small deer yards associated with these coniferous stands.
