We use qualitative and quantitative methods to explore social and spatial relationships between land ownership and forest cover in the Oregon Coast Range. Using a Geographic Information System (GIS) and regression analysis, we tested for spatial relationships between the structure of land ownership and forest cover across 66 watersheds in the Oregon Coast Range. We found that forest cover diversity increased with land ownership diversity in these watersheds. Likewise the size and connectivity of forest patches were found to increase with the size and connectivity of land ownership patches respectively (land ownership structure of explains 38% of the variability of forest cover structure across these watersheds). We conclude that landscapes with mixed ownership provide greater habitat diversity, while landscapes with concentrated ownership provide less diverse but more connected forest habitat. Using qualitative research methods we conducted an exploratory case study of one Coast Range watershed to examine possible explanations for relationships between ownership and forest cover. In our case study we found land ownership to change dramatically over time. We also found economic, cultural, and environmental factors all to influence landowner decisions with respect to land use, management, and tenure. We conclude that interactions between these factors are recommend that future studies address this complexity, either in predictive models or policy suggestions. We also recommend that future research in landscape ecology address dynamics of land ownership by updating ownership maps and the ways in which owners are classified.

Globally, the physical structure of forests results from their environmental setting, disturbance history, and human management practices. Human management practices today arguably have the greatest impact on the types and patterns of forest structure through direct management and modification of disturbance regimes. Previous studies have found that land ownership affects forest cover, patch dynamics, structure, and ecosystem function and services. However, these assessments of forest structure across landscapes and ownerships have been limited by the availability of high-fidelity data across a large spatial extent. To expand upon prior research, I used airborne lidar to assess the multi-scalar patterns of forest structure across a large (471,000 hectare), multi-owner landscape of the Oregon Coast Range. I examined forest structure patterns by identifying six statistically distinct classes of forest structure and then examining their distribution across and within ownership types. I used these structure classes to examine their area within each ownership class, mean patch size, and intermixing at multiple scales. I found that the six different forest structure classes in the study area can be interpreted as two assemblages, production-style forests principally on private lands and structurally complex forests principally on public lands. I found that land ownership objectives manifested in the physical landscape pattern of forest structure as measured by mean patch size and intermixing of structures. Finally, I found that landscape pattern of forest structure varied across scales as well as between ownerships. These results can be used to aid in monitoring and implementation of conservation strategies, for instance, in the monitoring of structurally complex forest and Northern Spotted Owl habitat and implementation of the Oregon Forest Practices Act.

Old-growth forests provide unique habitat features and landscape functions compared to younger stands. The goals of many forest mgmt. plans in the Pacific NW include increasing the area of late-successional and old-growth forests. This study describes existing old-growth forests in the northern Oregon Coast Range that might serve as examples of desired future conditions and developmental pathways. Results suggest that although old-growth forests can develop along multiple pathways, stand composition and productivity constrain development such that expecting all late-successional stands to have the full complement of old-growth attributes may not be realistic. Illustrations. This is a print on demand report.

A compilation of abstracts of papers presented at the 8th International Symposium on Society and Resource Management, held June 17-22, 2000. The abstracts explore the social dimensions of managing spatial landscapes for various purposes. The theme of the symposium, "Transcending Boundaries: Natural Resource Management form Summit to Sea," provided participants with the opportunity to explore the challenges of working across conceptual, cultural, and physical boundaries. The symposium focused on how social science research is being brought to bear on the exploration of "boundary issues" in resource management.

This major volume presents a wealth of fundamental and applied research on managing Coast Range forest and stream ecosystems. Written primarily for managers and resource specialists, the book will also appeal to policymakers, resource scientists, forest landowners, the conservation community, and students interested in forestry, fisheries, and wildlife sciences.
