Effects Of Fire Management Of Southwestern Natural Resources

The proceedings is a collection of papers and posters presented at the Symposium on Effects of Fire Management of Southwestern Natural Resources held in Tucson, Arizona, November 15-17, 1988. Included are papers, poster papers and a comprehensive list of references on the effects of fire on: plant succession, cultural resources, hydrology, range and wildlife resources, soils, recreation, smoke management, and monitoring techniques pertinent to prescribed fire management in the southwestern United States.

This synthesis provides an ecological foundation for management of the diverse ecosystems and fire regimes of North America, based on scientific principles of fire interactions with vegetation, fuels, and biophysical processes. Although a large amount of scientific data on fire exists, most of those data have been collected at small spatial and temporal scales. Thus, it is challenging to develop consistent science-based plans for large spatial and temporal scales where most fire management and planning occur. Understanding the regional geographic context of fire regimes is critical for developing appropriate and sustainable management strategies and policy. The degree to which human intervention has modified fire frequency, intensity, and severity varies greatly among different ecosystems, and must be considered when planning to alter fuel loads or implement restorative treatments. Detailed discussion of six ecosystems--ponderosa pine forest (western North America), chaparral (California), boreal forest (Alaska and Canada), Great Basin sagebrush (intermountain West), pine and pine-hardwood forests (Southern Appalachian Mountains), and longleaf pine (Southeastern United States)-- illustrates the complexity of fire regimes and that fire management requires a clear regional focus that recognizes where conflicts might exist between fire hazard reduction and resource needs. In some systems, such as ponderosa pine, treatments are usually compatible with both fuel reduction and resource needs, whereas in others, such as chaparral, the potential exists for conflicts that need to be closely evaluated. Managing fire regimes in a changing climate and social environment requires a strong scientific basis for developing fire management and policy.

A comprehensive exploration of the effects of fires--in forests and other environments--on soils, watersheds, vegetation, air and cultural resources.

Fire events often have a large impact on recreation and tourism, yet these issues had not been addressed from a social science perspective. There are three distinct lines of research to address: examine values/attitudes and behaviors of recreation residence owners and year-round residents in the wildland-urban interface; examine recreationists¿ perceptions about fire suppression and postfire forest health issues; and examine perceptions and beliefs about recreation activities and impacts to fire-prone ecosystems in the wildland-urban interface. This report includes 17 of these studies grouped into four major topical headings: recreation use research, commun. research, program eval. and interface residents research, and trust research.
