The Central Region includes Sandoval, Bernalillo, Valencia and Torrance counties. A high degree of geographic diversity is represented in this region which includes the Valles Caldera, the Middle Rio Grande valley, the Sandia and Manzano mountains, and the plains to the east of these mountains. Land ownership is primarily private with some Bureau of Land Management, Santa Fe and Cibola National Forest, State Trust and tribal lands. The city of Albuquerque and the surrounding communities drive the economic as well as the land and water use patterns for much of the Middle Rio Grande valley. Predominate rural economic activities and land uses include farming, ranching, tourism, ranchette development and military research and defense installations. NMLC has protected over 15,000 acres of land in the Central Region. With population pressures expected to increase significantly in the coming years, particularly in the Albuquerque greater metropolitan area, NMLC is working to preserve key pieces of open space, wildlife habitat and agricultural land in this central part of the state.
