Southwestern Willow Flycatcher Habitat Suitability 2008: Highway 60 Downstream to Elephant Butte Reservoir, NM.

摘要

In 2008, the Bureau of Reclamation (Reclamation) conducted a Geographic Information Systems (GIS) -based inventory and mapping project that included riparian areas along the Rio Grande from Highway 60 to Elephant Butte Dam in New Mexico. This mapping effort was based on 2007 photography. Mapping methods employed a classification system created by the Middle Rio Grande Biological Survey (Hink and Ohmart 1984) with minor modifications. Hink and Ohmart conducted an exhaustive biological analysis of the Rio Grande that included a classification of vegetation community and structure in the riparian zone of the river (levee to levee). In addition, bird and mammal abundance were correlated with vegetation types, making this system useful for determining the wildlife value of vegetation in the area.
