Site Description

The Bosque Del Apache Wildlife Refuge site (BDAS) was established in August-September 1999 and originally funded by NASA. The site is located between the river and the levee-FCC is at least 80 ha (198 acres), with an average width of about 350 m (1148 ft). It’s actual location is 33.781129˚N and 106.877225˚W at an elevation of 1374.93m above sea level. The soil at this site is strongly influenced by summer flood pulses from the Rio Puerco, as illustrated by the deep silty clay soil profile.

New Mexico State University installed 12.2 m (40 ft) tower in the saltcedar area with funding from the US Bureau of Reclamation. A full-time OPEC system was mounted on the tower at the time of construction. The University of New Mexico, with funding from the National Aeronautic and Space Administration (NASA), add a full-time 3SEC system to the tower. This site is currently operating.

Vegetation

The vegetation at this site is dense monospecific saltcedar (Tamarix chinensis). The overall canopy height is 6.1 m tall.

Hydrologic Status

This site has a 2-3 yr interflood interval. Most flooding is due to overland flow from an upstream overbank site. The site area has thick clay lenses (>2m), which prevents groundwater and surface floodwater interactions.
