March 2012: FRCC Workshop – (Albuquerque, NM and Flagstaff, AZ)

by swfscEvents, WorkshopsPosted on Comments are Disabled

Fire Regime Condition Class (FRCC) assessments have been widely used for evaluating ecosystem status in many areas of the U.S. FRCC employs state-and-transition modeling to describe historical vegetation and fire regimes, which provides reference information related to landscape fire frequency, severity, and vegetation composition. Similarity indexing is used to compare historical versus current vegetation and …

June 22, 2011: Fire history and age structure patterns at landscape scales

by swfscEvents, WebinarsPosted on Comments are Disabled

Presenter: Jose Iniguez (USFS RMRS) Top-down regional climate patterns result in high spatial fire synchrony among Southwest forests. At landscape scales, however bottom-up (topography) patterns are also important in determining fire history and tree age structure variability. The distinct fire histories from these two study areas provided natural age structure experiments that indicated tree age …

February 15, 2011: Effectiveness of post-fire seeding and herbicide treatments to battle cheatgrass in Zion National Park

by swfscEvents, WebinarsPosted on Comments are Disabled

Presenter: Andrea Thode (Northern Arizona University) Fine fuels from non-native, annual brome grasses have overcome native plants across much of Zion Canyon in Zion National Park. This invasion threatens the single road that provides access into—and escape from—the canyon, creating a threat to human life should a large wildfire occur there. In addition, native riparian …

March 18, 2012: Fire Regime Condition Class Mapping Tool

by swfscEvents, WebinarsPosted on Comments are Disabled

Presenters: Steve Barrett & Jeff Jones (NIFTT University of Idaho) The FRCC Mapping Tool quantifies the departure of vegetation conditions and fire regimes from a set of reference conditions representing the historical range of variation. The tool, which operates from an ArcGIS platform, derives several metrics of departure (e.g., vegetation composition and structure, fire severity, …
