The Kemble Rock Nature Reserve rises northwest of village of Kemble, on a high Escarpment promontory near the shores of Georgian Bay.  Its 200 acres includes regenerating fields, meadows, a wetland, and a gentle rise up to the steep craggy cliffs of the Niagara Escarpment. Preservation of the Kemble Nature Reserve secures 1.3 km of the Bruce Trail's Optimum Route.

The northern portion of Kemble Rock Nature Reserve lies within a portion of the Kemble Forest Regional Life Science Area of Natural and Scientific Interest (ANSI). The ANSI is an important link in a 30 km natural corridor (ca. 150 square km) containing Skinners Bluff, Slough of Despond, Mountain Lake Fen, The Glen and Bass Lake Escarpment, and the wetlands of Mountain Lake, McNab Lake and Shallow Lake.

Kemble Rock Nature Reserve contains a variety of habitats, the most dominant of which are deciduous forest and regenerating agricultural land, which is now transitioning to native trees and shrubs that have seeded in from the surrounding forests and fencerows. The emerging forest contains young Sugar Maple, White Ash, White Elm and Hawthorns, and provide excellent habitat for certain bird species, particularly the Brown Thrasher, Blue-winged Warbler and Gray Catbird.
A stream runs through the southeastern portion of Kemble, which feeds a sizeable swamp dominated by Swamp Maple and Black Ash and is habitat for birds such as the Northern Waterthrush. This ecosite is perfect for orchids to thrive.

The remainder of the Kemble Rock Nature Reserve contains a mature deciduous forest. The dominant tree species in this forest are Sugar Maple, American Beech and White Ash, with Ironwood comprising a large component of the understorey. Due to the large size of the forested lands on the property, there is significant ‘interior forest' habitat (defined as forested land that is 100 m away from a forest edge). Interior forest habitat is extremely important for numerous species such as the Pileated Woodpecker, Ovenbird, Black-throated Blue Warbler and the Wood Thrush and Eastern Wood-pewee, both species of Special Concern.

The rocky Escarpment slopes on the property provide habitat for the Endangered Butternut tree as well as the globally rare Hart's Tongue Fern, a species of Special Concern.
