Description    


The Nature Conservancy (TNC) will purchase a conservation easement (CE) on the Peterson Ranch, located in the Lemhi River valley and complete habitat restoration actions on the property. The CE will permanently protect 181-acres of working ranchland and wildlife habitat, and 0.60 miles of Hayden Creek and the Lemhi River. The purchase is downstream adjacent to the Split River Ranch Conservation Easement (021 16 SA), expected to be close in April 2020. The two easements together will protect a continuous 0.16 miles of Hayden Creek, and 1.2 miles of the Lemhi River.



Restoration work identified in the Peterson Ranch Conservation Easement (CE) will obligate the landowner to complete habitat restoration activities to increase juvenile rearing capacity within the easement bounds. These activities will commence over the next 1-5 years following easement closure and have specific language in the easement to perform the restoration concept on both Hayden Creek and Lemhi River. Instream habitat project actions include the construction of side channels, adding meanders, installation of wood and rock instream structures, scour pools, streambank stabilization, and floodplain activation. Riparian habitat actions include planting, fencing, and grazing management.



Restoration work will increase high quality riparian and floodplain habitat important for Chinook salmon and steelhead during juvenile life stages. The concept plan includes over 0.2 miles of restoration channel length on Hayden Creek and over 0.5 miles of restoration channel length on the Lemhi River. The CE and accompanying habitat restoration actions will address limiting factors to anadromous fish recovery in the Lemhi River that are specifically identified in recent habitat assessments including the IRA (Idaho OSC Team (Idaho Governor’s Office of Species Conservation and partners). 2019. Upper Salmon Subbasin Habitat Integrated Rehabilitation Assessment. Assessment prepared for and with the U.S. Department of the Interior, Bureau of Reclamation. June 2019. 625 pp.)

Project Benefit    


1. Permanently protect 181 acres of working ranchland and wildlife habitat

2. Permanently protect .60 miles of Hayden Creek and the Lemhi River

3. Obligate the landowner to river restoration activities that will address juvenile rearing capacity

limitations in the Lemhi watershed. These activities will include the construction of side channels,

instream habitat work, and activating floodplain connectivity.
