Extirpated Species

A number of plants and animals that were once native to Grand Canyon can no longer be found within its' boundaries. Native plants and animals that are no longer present in a place that was once their home are called extirpated species. The Glen Canyon Dam Adaptive Management Program has a goal to restore populations of extirpated species, to the extent feasible and advisable.

Desired Future Condition for Extirpated Species

Re-establish fishes extirpated from Grand Canyon, where feasible and consistent with recovery goals for humpback chub and the recovery goals of those extirpated fishes.

  • The 2009 park profile for Grand Canyon National Park prepared by the National Park Service lists the following species as extirpated: grizzly bear, black-footed ferret, gray wolf, jaguar, Bear Valley sandwort, Colorado pikeminnow, bonytail, roundtail chub, and northern leopard frog.
  • The CFMP-EA does not propose management actions to reintroduce extirpated species to the project area; however, reintroduction feasibility studies conducted over the life of the plan would undergo subsequest NEPA analysis. (NPS CFMP-EA_pg59)
