project will generate burn severity data, maps, and reports, which will be available for use at local, state, and<br />

national levels to evaluate trends in burn severity and help develop and assess the effectiveness of land<br />

management decisions. Additionally, the information developed will provide a baseline from which to monitor<br />

the recovery and health of fire-affected landscapes over time. Spatial and tabular data quantifying burn severity<br />

will augment existing information used to estimate risk associated with a range of current and future resource<br />

threats. The annual report of 2004 fires has been completed. All data and results will be distributed to the public<br />

on a Web site.<br />

Abstract Ecological land classification systems have recently been developed at continental, regional, state, and<br />

landscape scales. In most cases, the map units of these systems result from subjectively drawn boundaries, often<br />

derived by consensus and with unclear choice and weighting of input data. Such classifications are of variable<br />

accuracy and are not reliably repeatable. We combined geographic information systems (GIS) with multivariate<br />

statistical analyses to integrate climatic, physiographic, and edaphic databases and produce a classification of<br />

regional landscape ecosystems on a 29 340-km² quadrangle of northwestern Wisconsin. Climatic regions were<br />

identified from a high-resolution climatic database consisting of 30-yr mean monthly temperature and<br />

precipitation values interpolated over a 1-km² grid across the study area. Principal component analysis (PCA)<br />

coupled with an isodata clustering algorithm was used to identify regions of similar seasonal climatic trends.<br />

Maps of Pleistocene geology and major soil morphosequences were used to identify the major physiographic<br />

and soil regions within the landscape. Climatic and physiographic coverages were integrated to identify regional<br />

landscape ecosystems, which potentially differ in characteristic forest composition, successional dynamics,<br />

potential productivity, and other ecosystem-level processes. Validation analysis indicated strong correspondence<br />

between forest cover classes from an independently derived Landsat Thematic Mapper classification and<br />

ecological region. The development of more standardized data sets and analytical methods for ecoregional<br />

classification provides a basis for sound interpretations of forest management at multiple spatial scales.<br />
