How an FIA adjunct inventory can be used to assess climate change impacts on species distributions John Morton Kenai National Wildlife Refuge "Not everything that can be counted counts, and not everything that counts can be counted." - Albert Einstein (18791955) “… resource managers do not have sufficient site-specific information to plan for and manage the effects of climate change on the federal resources they oversee. [They] generally lack detailed inventories and monitoring systems to provide them with an adequate baseline understanding of the plant and animal species that currently exist on the resources they manage. For example, at the Chugach National Forest, managers told us that without accurate baseline inventory data of the plants and animals in the forest, it is difficult to determine whether changes to species populations are within the normal range of variability.” GAO Aug 2007 Climate Change: Agencies Should Develop Guidance for Addressing the Effects on Federal Land and Water Resources “Few DOI land management units have complete biological inventories of species. Additionally, DOI has no cohesive, systematic program for monitoring change over time in the distribution of species and communities. Inventories will be critical to assessing climate change impacts and to developing management responses to those impacts…” DOI Climate Change Task Force Feb 2008 Pre-decisional draft “The USFWS has an extensive inventory and monitoring program…However, inventory and monitoring plans often have little programmatic or geographic integration. The effects of climate change on Alaska flora and fauna are predicted to be far-reaching, and the Service’s ability to modify its management objectives and strategies in response to these changes may require a reconsideration of current inventory and monitoring efforts… “ USFWS R7 Climate Change Forum Inventory & Monitoring Breakout Group, Feb 2007 SOLUTION?

Objectives …would be scaled to detect changes in flora, fauna, and other metrics at the regional and/or national level. This program would consist of permanent sampling sites, ideally integrated and cost-shared with existing national monitoring programs such as the USDA Forest Inventory & Analysis program… Data resulting from this proposed I&M program can be used to model spatially-explicit distributions of biota now and into the future as a result of climate change.” Four Key Ideas to Guide the U.S. Fish and Wildlife Service’s Response to Climate Change Feb 2008 10,000 FIA plots on Federal lands in Alaska!?
