The Lower Pecos and Black Rivers Conservation Opportunity Area (COA) encompasses 26,918 ha (66,516 ac) that extends along the Pecos River from Brantley Lake to 10 km (6 mi) south of the confluence with the Black River, and along the Black River from the Guadalupe Mountains to its confluence with the Pecos River. Most of the COA is privately-owned (55%), but sizable portions are managed by the Department (16.5%) and BLM (14%). It contains three Important Bird Areas (Brantley Lake State Park, Six-Mile Dam, Laguna Grande Complex) and two TNC conservation areas (Remuda/Big Sinks, Black River Basin). Twenty percent of the COA is protected. Landcover includes nine native vegetation habitats plus substantial amounts of open water and agricultural and developed lands. Chihuahuan Desert Scrub is the dominant habitat (71%). Perennial aquatic habitats include 236 km (147 mi) of warm water streams and 615 ha (1,520 ac) of warm water reservoirs.
