Abstract

ASSESSING LAND COVER COMPOSITION AND CONFIGURATION ALONG ROUTES OF THE NORTH AMERICAN BREEDING BIRD SURVEY

The distribution and abundance of bird species along Breeding Bird Survey routes is undoubtedly influenced by the composition and configuration of land cover along the routes. Assessments of land cover along routes can inform us as to whether the routes are representative of larger landscapes and regions. Such information can be useful in making inferences from the bird data, regardless of whether one is studying bird-habitat relationships or using the BBS data for some other purposes. The National Land Cover Database (NLCD) is one of the most extensive GIS-based sources of land cover data for the continental USA. It is both an inventory and a monitoring instrument in that an updated version is released about every five years. The NLCD is based on remote-sensing imagery primarily from the Landsat satellites. The NLCD classifies each of about 27 billion 30 x 30 m pixels to one of 16 land cover types representing natural as well as anthropogenic land. NLCD data have been used previously to assess local and regional representativeness of BBS routes and to examine bird-habitat relationships at landscape and biogeographic scales. These studies will be discussed along with on-going research that investigates temporal changes in land cover along BBS routes.
