The U.S. Fish and Wildlife Service reviewed a petition to classify the Rio Grande cutthroat trout as endangered or threatened but found that it is not warranted at this time. This trout, which inhabits high-altitude streams in New Mexico and Colorado, faces threats such as hybridization with nonnative trout and habitat threats like wildfires and climate change. However, current conservation efforts, including a multi-agency agreement, have helped improve its population's resiliency. As a result, the Service concludes that the trout is not currently in danger of extinction throughout its range, nor is it likely to become endangered soon.
Simple Explanation
The U.S. Fish and Wildlife Service decided that the Rio Grande cutthroat trout, living in streams in New Mexico and Colorado, does not need to be listed as endangered right now because it's doing okay thanks to some help from conservation groups. But they still want people to share any new information if things change for the fish.
