Stone Road Alvar Conservation Area



With this Conservation Area, getting there is half the fun since it is located a boat ride away on Pelee Island. The alvar is an area of thin topsoil over limestone bedrock, a very unique ecosystem and one of the region's most biologically diverse, supporting some 55 native alvar plants. Rare species include: the Blue Racer Snake, Giant Swallowtail Butterfly, Yellow breasted Chat and Chinquapin Oak. The area also includes a rocky limestone shore. There is no formal trail but the area is yours to explore.

Stone Road Alvar Conservation Area is a Critical Natural Area




Stone Road Alvar has the most extensive, most diverse, and best-quality alvar habitat in the Carolinian zone. Due to its location in Canada's "Far South", the site has many Carolinian elements -- some occur nowhere else in Canada -- yet it also shares many species with the alvars of eastern Ontario. A large number of imperiled native species are found here including Blue Ash, Nodding Onion, Whorled Milkweed, Elm-leaf Goldenrod, Field Pansy, Yellow Horse-gentian, Prairie Rose, and Wild Hyacinth. This Chinquapin Oak savanna-alvar ecosystem occurs nowhere else in ithe world, making it globally significant.

Of the 200-ha that comprise Stone Road Alvar, a significant portion has been purchased for conservation by Ontario Nature (Federation of Ontario Naturalists), Essex Region Conservation Authority, Nature Conservancy of Canada, and Wilds of Pelee Island.



Alvars are unique ecosystems that occur on flat glaciated limestone bedrock where soils are thin or absent and distinct associations of plants have adapted to seasonal drought and flooding. Most of North Amercia's alvars occur in the Great Lakes basin, and the majority are in Ontario (taken from the Carolinian Canada Signature Sites Guide by Lorraine Johnson 2005).
