The Carden Alvar holds many treasures. Situated northeast of Lake Simcoe in Ontario, it covers some 7900 acres of protected land. Formed over 10, 000 years ago when the glaciers retreated, it is comprised of a thin layer of soil on limestone rock. Not suitable for farming, it is now a retreat for a number of endangered plants and animals. It is comprised of grassland, shrubland, forests and wetlands and supports 450 plant species, 142 butterfly and dragonfly species and 238 bird species. (Nature Conservancy Canada)
Thank you to the land owners of this region who have granted their land to the watchful eye of the Nature Conservancy. A note to all who would venture here, wear water proof foot ware. The trail can become a little thin in places, so looking at an online map of the area is helpful.
