Wintering Grassland Bird Densities in Chihuahuan Desert Grassland Priority Conservation Areas, 2007-2010

March 15, 2011 83 pages

Description

This first-ever, region-wide pilot survey was initiated to inventory, research and monitor wintering birds at randomly-selected sites in Grassland Priority Conservation Areas (GPCAs) in the Chihuahuan Desert in northern Mexico and western Texas. It generated data on habitat conditions and abundance of 50 grassland obligate or facultative species in the 11 GPCAs, including 30 priority species of high regional or continental conservation interest.

Many grassland bird species are of high conservation concern due to major population declines and continuing habitat loss and degradation. These grasslands are increasingly being lost and degraded through agricultural conversion, desertification and shrub encroachment, especially in Mexico.
