Coastal Landscape Analysis and Modeling Study

The CLAMS Project

The Coastal Landscape Analysis and Modeling Study (CLAMS) is a joint research effort of the USDA Forest Service, Pacific Northwest Research Station, Oregon State University, College of Forestry and the Oregon Department of Forestry. The goal of CLAMS is to develop and evaluate concepts and tools to understand pattern and dynamics of provincial ecosystems such as the Oregon Coast Range and to analyze the aggregate ecological and socio-economic consequences of different forest policies and strategies across multiple ownerships of the province. The six major objectives of the project are to:

  1. Characterize the spatial pattern and history of ecological and socio-economic components of the Coast Range;
  2. Develop ecological and socio-economic models, measures and linkages (Figure1);
  3. Develop spatial policy evaluation tools and data for use by technical specialists;
  4. Project aggregate effects of current and selected alternative forest policies on key resources and outputs;
  5. Evaluate consequences of alternative fundamental strategies to natural resource management;
  6. Synthesize multi-scale assessments and provide information for joint learning among stakeholders.

These objectives will be met through development of a compatible set of spatial data bases and spatial simulation models. Vegetation and physical conditions of the province will be characterized with GIS models that use LANDSAT imagery, 10 m digital elevation models and climate and geology data. Landowner behavior (land use change and timber harvesting practices) will be simulated based on landowner surveys. Coarse and fine scale measures of biodiversity will be developed from the literature, limited field studies and analysis of existing data. Habitat suitability models (fine scale measures) will be developed for selected species and validated where possible against existing field study data. Aquatic habitat potential measures for salmonids will be developed at the watershed scale. Indicators of landslide and debris flow potential will be developed. A spatial forest dynamics simulator will be used to project harvesting and stand growth under current and alterative policies for 100 years. A stand growth and yield model (Organon) and a forest succession model (Zelig) will be used to project forest development. Economic effects will be estimated using IMPLAN. Recreational opportunities and contingent valuation of biological diversity will also be evaluated.
