Species composition and population viability are
often affected by the structure of the landscape; for example, thesize, shape, and connectivity of individual patches of ecosystems
within the landscape (
Noss, 1990 ).
Conservation management should be directed at whole landscapes toensure the survival of species that range widely across different

Diversity within and between landscapes depends on local and regional variations in environmental conditions, aswell as the species supported by those environments. Landscape diversity is often incorporated into descriptions " ecoregions ,"
