ECOSYSTEM MANAGEMENT AND CONSERVATION BIOLOGY

Ecosystem management argues for the maintenance of native biological d iversity, in addition to commodity and amenity uses, on our public lan ds. Heretofore, natural resource management agencies have focused on m anaging for single species, usually those that are commercially valuab le, threatened or endangered, or over-abundant. For a variety of reaso ns, the future of public-land management will place increasing importa nce on managing for species communities. Three approaches which can be used to manage for communities include: (1) a species approach, (2) a n ecological processes approach, and (3) a landscape approach. Each me thod is briefly discussed.
