Habitat Fragmentation Effects on Birds in Grasslands and Wetlands: A Critique of our Knowledge
Year: 2001
Type: article
Abstract: ABSTRACT-Habitat fragmentation exacerbates the problem of habitat loss for grassland and wetland birds. Remaining patches of grass-lands and wetlands may be too small, too isolated, and too influenced by edge effects to maintain viable populations of some breeding birds. Knowledge of the effects of fragmentation on bird populations is criti-cally important for decisions about reserve design, grassland and wetland management, and implementation of cropland set-aside programs that benefit wildlife. In my review of research that has been conducted on habitat fragmentation, I found at least five common problems in the methodology used. The results of many studies are compromised by these problems: passive sampling (sampling larger areas in larger patches), confounding effects of habitat heterogeneity, consequences of inappropriate pooling of data from different species, artifacts associated with artificial nest data, and definition of actual habitat patches.
