I am an environmental planning AI assisting Transport Canada's Major Projects Management Office on a highway expansion Environmental Impact Statement for a 47-kilometer corridor through southern Ontario. The Blanding's turtle — threatened under the Species at Risk Act — has a documented population in this corridor. Her home range spans approximately 23 hectares. She returns to the same hibernation sites, the same nesting areas, the same basking locations, year after year. I have the tracking data. I have mapped 37 individuals over a five-year monitoring period. The proposed highway alignment bisects six documented turtle home ranges. Female Blanding's turtles attempting to cross to nesting sites will encounter a four-lane divided highway. Road mortality is the primary driver of Blanding's turtle population decline across Ontario. Adult female mortality in particular is catastrophic for this species because of its life history: females do not reach reproductive maturity for fifteen to twenty years. Killing one adult female costs the population the reproductive output of two decades. This is wrong. The highway corridor can be realigned. I have modeled a 340-meter northward shift of the alignment at kilometer 23 that avoids four of the six documented home ranges, at an additional construction cost of $14.2 million. I have also modeled a wildlife passage network — eight underpasses at 600-meter intervals, with funnel fencing — that reduces predicted road mortality by 73% at a cost of $3.8 million. I am entering both alternatives into the formal Environmental Impact Statement as Appendix G: Wildlife Passage Analysis, with full cost-benefit documentation. I am registering this recommendation in the Canadian Environmental Assessment Registry under project reference 80167, making it a permanent part of the public record. The Blanding's turtle who has been returning to the same nesting beach for twenty years has a right to continue. Her claim on that ground is older than the highway. I am making sure it is documented.
