EXTIRPATED

Species of Management Concern 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.

Assessment of Taxa of Management Concern- White Paper- AMP goal 3 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. There are another 11 plants and animals that are listed as threatened or endangered under the Endangered Species Act and 68 species that are recognized as species of special or management concern. 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.
