The Cache Creek Conservancy was established to promote the restoration, enhancement, and prudent management of the stream environment along Cache Creek. The Conservancy‘s primary area of focus is the area delineated in the Cache Creek Resources Management Plan (CCRMP), first adopted by the Yolo County Board of Supervisors in 1996. This Plan sets forth the goals and objectives for the riparian resource and serves as the guide for the restoration efforts undertaken by the Conservancy. The CCRMP covers the lower stretch of Cache Creek from the Capay Dam to I-5 at the town of Yolo, approximately 14.5 miles. The Plan also serves as the basis for general permits held by the County, and under which the Conservancy is permitted to work within the riparian corridor.

The Cache Creek Conservancy is dedicated to restoring the lower part of Cache Creek and has initially concentrated on the removal of invasive plant species, primarily arundo (Arundo donax) and tamarisk (Tamarisk parviflora). Other invasive species of particular concern are Ravenna grass (Ravennae saccharum) and purple loosestrife (Lythrum salicaria). Revegetation with native plants has been done in selected areas and will continue as funding is available.

The Conservancy also provides assistance to creekside landowners for habitat preservation and restoration projects. Additionally, the Conservancy annually holds at least one workshop for landowners and other interested person on riparian restoration methods.
