| Abstract | A spatially realistic population model (SRPM) was developed to evaluate the relative effects of different habitat management strategies on the spotted owl subpopulation of the Olympic Peninsula. SPRMs address a fundamental problem commonly confronted by wildlife managers- predicting the effects of landscape-scale habitat management on animal population. The most frustrating problem with SRPM is the lack of data needed to relate movement and demographic parameters to habitat quality. SPRMs typically consist of three submodels: (1) a habitat submodel, (2) a movement submodel, and (3) a demographic submodel. Habitat submodel must interface with the demographic and movement submodels. That is, the submodel should delineate landscape units that have demographic significance, such as territories, or that may be relevant to movement behavior, such as habitat corridors. In this case study a new approach called 'parameter tuning ' was developed to generate parameter values. |
