Loss of habitat can adversely affect biodiversity by reducing or eliminating available habitat for individual species, altering population dynamics and ecological interactions, or changing biophysical processes that ultimately sustain critical ecological and evolutionary processes. Habitat fragmentation contributes both to habitat loss and habitat degradation. Ecological and population integrity can be compromised through habitat degradation. Specific forms and effects of habitat degradation will vary in different major habitat types, but impacts on species ranges, population dynamics, ecological interactions, and biophysical drivers can be generally derived for every ecoregion.
