Evidence to suggest this comes largely from radio telemetry data from both blue racers and eastern fox snakes that inhabited the same general areas on Pelee Island (although studies were not conducted concurrently).

Probable natural predators of adult blue racers include the larger birds of prey (e.g., red-tailed hawk, northern harrier, great horned owl) and carnivorous mammals such as raccoons, foxes and coyotes.

Intra- and interspecific (with the eastern fox snake) communal nest sites have been documented and appear to be relatively common.

Consequently, habitat determined to be critical to the snake's persistence is protected (from destruction or significant alteration) under Ontario's Endangered Species Act (ESA).

In 1998, blue racer "habitat" on Pelee Island was spatially delineated (primarily utilizing mark-recapture and radio telemetry data collected from 1990 to 1998) and formally identified for the Conservation Land Tax Incentive Program, Ontario Ministry of Natural Resources (OMNR).

Subsequent to the spatial delineation (or mapping) of this habitat, the OMNR determined that these lands should be protected from destruction or human interference as is required under the ESA.

Unfortunately, implementing a program to effectively protect endangered species habitat on private lands has been extremely difficult.

Several areas are known to harbor blue racers and the important microhabitats used by them (e.g., hibernacula) are formally protected on Pelee Island.

Lighthouse Point Provincial Nature Reserve and the Stone Road Alvar Complex (owned and managed by the Federation of Ontario Naturalists, Essex Region Conservation Authority, and Nature Conservancy Canada) are the two most important protected areas for the blue racer.
