Proposed Kern River Rainbow Trout Project for Sequoia National Park

The public is welcome to comment on a project proposed by the California Department of Fish and Wildlife (CDFW) to collect genetically pure Kern River rainbow trout (KRRT) from three populations located in the wilderness of Sequoia National Park. The State of California, through its Heritage and Wild Trout Program proposes to restore the naturally indigenous Kern River rainbow trout to their original California source watersheds. In 2013, CDFW determined that Sequoia National Park supports the best populations of KRRT for conservation and native source watershed restoration.

National Park Service (NPS) Management Policies 2.4.4, states that a take of wildlife may be allowed if it supports cooperative species conservation purposes. The proposed project is consistent with the conservation purpose of the Wilderness Act and the National Park Service's mission. National parks and wilderness areas are increasingly the only source for genetically pure native species. Interestingly, the purity of the source populations in Sequoia National Park is an artifact of past wildlife management practices when fish were routinely introduced to park waterbodies from the late 1800s to the late 1900s. The KRRT is native to Sequoia National Park in the mainstem Kern River, where it has completely hybridized with non-native stocked trout. The populations involved in this project were transplanted from the Kern River before the native population became hybridized.

The fish would be removed via angling and held in water receptacles for transport. This method is a proven fisheries management practice with a high success rate. A total of 100 fish at least 4 inches long would be collected and transported from each population to the Kern River Fish Hatchery in Kernville, California for propagation. Fifty fish from each population would be collected per year for two years to minimize potential for short-term adverse impacts on the three source populations. Visual estimates of KRRT abundance collected over the past few years indicate that the parks' KRRT populations are of sufficient size such that proposed collections should not impact long-term sustainability.

The proposed action would enable a genetically pure strain native trout to be restored to former habitat where it is expected to enhance wilderness and non-wilderness recreational experiences in its "original California source watersheds."

The NPS is interested in any public concerns, potential issues, or opportunities related to the trout collection. After analyzing comments received during scoping, the NPS will determine the level of analysis needed.
