| Abstract: | A common approach to land use change analyses in multidisciplinary landscape-level studies is to delineate discrete forest
and non-forest or urban and non-urban land use categories to serve as inputs into sets of integrated sub-models describing
socioeconomic and ecological processes. Such discrete land use categories, however, may be inappropriate when the socioeconomic
and ecological processes under study are sensitive to a range of human habitation. In this paper, we characterize the spatial
dynamic distribution of humans throughout the forest landscape of western Oregon (USA). We develop an empirical model describing
the spatial distribution and rate of change in historic building densities as a function of a gravity index of development
pressure, existing building densities, slope, elevation, and existing land use zoning. We use the empirical model to project
changes in building densities that are applied to a 1995 base map of building density to describe future spatial distributions
of buildings over time. The projected building density maps serve as inputs into a multidisciplinary landscape-level analysis
of socioeconomic and ecological processes in Oregon's Coast Range Mountains.
