Description: Private forestlands in the United States face increasing pressures from growing populations, resulting in greater numbers of people living in closer proximity to forests. What often is called the "wildland/urban interface" is characterized by expansion of residential and other developed land uses onto forested landscapes in a manner that threatens forestlands as productive socioeconomic and ecological resources. Prevailing hypotheses suggest that such forestlands can become less productive, because forest owners reduce investments in forest management. We develop empirical models describing forest stocking, thinning, harvest, and tree planting in western Oregon, as functions of stand and site characteristics, ownership, and building densities. We use the models to examine the potential impacts of population growth and urban expansion, as described by increasing building densities, on the likelihood that forest owners maintain forest stocking, pre-commercial thin, harvest, and plant trees following harvest. Empirical results support the general conclusion that population growth and urban expansion are correlated with reduced forest management and investment on private forestlands in western Oregon (USA). Results have potential implications for both economic outputs and ecological conditions, as well as for wildfire risks at the wildland/urban interface.
Keywords: Urbanization, wildland/urban interface, nonindustrial private forest owners
