Recovery Plan for the Northern Spotted Owl - DRAFT

Hummocky - a landscape characterized by small, well-drained areas risingabove the general level of poorly-drained land.Hybrid - an offspring that results from the mating of individuals of differentraces or species.Hybridization - the crossing or mating of two different varieties of plants oranimals.Incidental take - 'take" of a threatened or endangered species that is incidentalto, and not the purpose of, the carrying out of an otherwise lawfulactivity.Inholding - land belonging to one landowner that occurs within a block of landbelonging to another. For example, small parcels of private land thatoccur inside national forests.Integrated pest management - a process for selecting strategies to regulateforest pests in which all aspects of a pest-host system are studied andweighed. Regulatory strategies are based on sound silvicultural practicesand ecology of the pest-host system and consist of a combination oftactics such as timber stand improvement plus selective use of pesticides.RGInteragency Spotted Owl Subcommittee - a subcommittee of the Oregon-Washington Interagency Wildlife Committee that was formed to recommendguidelines to federal land management agencies for the protectionof the northern spotted owl.Interspecific - occuring among members of different species.Interspecific competition - the condition of rivalry that exists when a numberof organisms of different species use common resources that are in shortsupply; or, if the resources are not in short supply, the condition thatoccurs when the organisms seeking that resource nevertheless harm oneor another in the process. Competition usually is confined to closelyrelated species that eat the same sort of food or live in the same sort ofplace. Competition typically results in ultimate elimination of the lesseffective organism from that ecological niche. WPGIntraspecific - occuring among members of single species.ISC (Interagency Scientific Committee) - a committee of scientists that wasestablished by the U.S. Forest Service, U.S. Bureau of Land Management,U./S. Fish and Wildlife Service, and National Park Service, to develop aconservation strategy for northern spotted owls.Isolate - a population that is isolated. See isolation.Isolation - absence of genetic crossing among populations because of distanceor geographic barriers. SAFJamison strategy - a spotted owl conservation strategy adopted by the U.S.Bureau of Land Management that included some but not all of the majorprovisions of the ISC strategy.Jeopardy - a finding made through consultation under the EndangeredSpecies Act that the action of a federal agency is likely to jeopardize thecontinued existence of a threatened or endangered species.652
