| Abstract | The Integrated Landscape Assessment Project (ILAP) was a multiyear effort to
produce information, maps, and models to help land managers, policymakers, and
others conduct mid- to broad-scale (e.g., watersheds to states and larger areas)
prioritization of land management actions, perform landscape assessments, and
estimate cumulative effects of management actions for planning and other purposes.
The ILAP provided complete cross-ownership geospatial data and maps on
current vegetation, potential vegetation, land ownership and management allocation
classes, and other landscape attributes across Arizona, New Mexico, Oregon,
and Washington. State-and-transition models, developed to cover all major upland
vegetation types in the four states, integrated vegetation development, management
actions, and natural disturbances to allow users to examine the mid- and long-term
effects of alternative management and disturbance scenarios. New model linkages
to wildlife habitat, economics, aboveground carbon pools, biomass, and wildfire
hazard were developed and integrated through decision-support systems. Models
incorporating potential effects of climate change were also developed for focus
areas in Oregon and Arizona. This report includes an overview of the structure and
components of ILAP along with descriptions of methods and example results for
state-and-transition modeling, fuel characterization, treatment economics, wildlife
habitat, community economics, and climate change. This report serves as a guide
to ILAP. Complete collections of the project’s models, maps, data, and tools will
be archived and available online through the Western Landscapes Explorer portal
(www.westernlandscapesexplorer.info) so that scientists and managers will be able
to use and build upon ILAP’s products.
