The 68.5 acre Dunedin Ravine Nature Reserve is located along the northern flank of the Noisy River Valley, near the Dunedin Regional Earth Science ANSI, and provides habitat for Butternut trees, Shining-branch Hawthorn and Bobolink, all of which are Species at Risk. The property is also home to the Northern Flicker, a priority bird species in Environment Canada's Bird Conservation Strategy. Its preservation secures 1.2 km of the Bruce Trail's Optimum Route.
Immediately south and southeast lie the Lavender Falls/Dunedin Park Regional Earth Science ANSI and the Lavender Falls Life Science ANSI. Several other Bruce Trail Conservancy Nature Reserves are found less than one km north. Collectively these lands are part of a continuous stretch of forests and wetlands that encourage species movement and provide habitat for wider ranging or migratory animals to move throughout the landscape.
