Three wildland provincial parks and one ecological reserve have been established in the northeast corner of Alberta. Colin-Cornwall Lakes, Fidler-Greywillow and La Butte Creek Wildland Provincial Parks are located in the Canadian Shield Natural Region. Egg Island Ecological Reserve, within Lake Athabasca, is also located in that Natural Region (Alberta Environmental Protection 1998). Note that Fidler-Greywillow is comprised of a strip of mainland plus some islands in Lake Athabasca. These protected areas contain numerous and important examples of Alberta's biodiversity. Much of it is poorly understood or unknown, particularly the invertebrate fauna. The spider fauna is no exception. The spider specimens that were collected in Colin-Cornwall Lakes Wildland Provincial Park during this survey were the first for this area.
