The Gila trout is native to New Mexico and Arizona but since 2006 they have been on the endangered species act and are only found in four rivers in the Gila National Forest.
During a fire in New Mexico in the Gila National Forest- four months ago- the trout were taken from the waters, and deposited in a hatchery for safe keeping. At the time of the fire there was potential flooding of the forests streams along with ash and charred debris. The trout were put in a huge tank and loaded into a helicopter that took them to a hatchery at the other end of the state. U.S Fish and Wildlife were able to use emergency funds to pay for the recuse and the return process of the trout.
Since the fire wildlife managers have been monitoring the area to decide when to bring the fish back home.
