As part of the Integrated Hardwood Range Management Program (IHRMP) we are dedicated to conserving California's oak woodland resources. The IHRMP is administered by the University of California's Division of Agriculture and Natural Resources whose mission is to serve California through the creation, development, and application of knowledge in agricultural, natural, and human resources. Adina Merenlender, principal investigator, is affiliated with the Ecosystem Sciences Division of the Environmental Science, Policy, and Management ( ESPM ) department at UC-Berkeley.

Primarily we focus on the major threats that oak woodlands face in the north coast: 1) population growth resulting in urban and suburban expansion, 2) a booming wine industry driving an expansion of hillside vineyards in oak woodlands, and 3) the cascading effects of land-use on the Russian River Basin. We are based at the Hopland Research and Extension Center in southern Mendocino County where we maintain a Geographic Information Systems laboratory to integrate biodiversity research, land use change information, and conservation planning on a landscape scale for North Coast hardwood rangelands.
