Essential Elements Of Sustainable Fire Management In The Wildland-Urban Interface, Christopher Dicus Nov 2006

Essential Elements Of Sustainable Fire Management In The Wildland-Urban Interface, Christopher Dicus

Natural Resources Management and Environmental Sciences

Fire and fuels management in the wildland-urban interface is a multifaceted aggregation of biophysical and sociopolitical components. To best insure sustainable communities in the wildland-urban interface, stakeholders from a diversity of disciplines and worldviews must collaborate to develop a management plan for a given area that minimizes fire risk while simultaneously maximizing the benefits that distinct vegetation types and structures provide. This paper discusses critical elements that must be considered in order to maintain sustainable communities in the wildland-urban interface. These factors include fuels treatments, suppression forces, enforceable infrastructure and construction standards, and community education, each of which will vary ...


Reduction Of Potential Fire Behavior In Wildland-Urban Interface Communities In Southern California: A Collaborative Approach, Christopher Dicus, Michael E. Scott Mar 2006

Reduction Of Potential Fire Behavior In Wildland-Urban Interface Communities In Southern California: A Collaborative Approach, Christopher Dicus, Michael E. Scott

Natural Resources Management and Environmental Sciences

This manuscript details a collaborative effort that reduced the risk of wildfire in an affluent, wildland-urban interface community in southern California while simultaneously minimizing the environmental impact to the site. FARSITE simulations illustrated the potential threat to the community of Rancho Santa Fe in San Diego County, California, where multimillion-dollar homes were located immediately above a designated open space area that consisted primarily of 60-year-old, decadent chaparral. Post-treatment fire behavior simulations demonstrated the potential ability to moderate fire behavior. Results of the fire behavior modeling led to a recognition for the need for fuels treatments by both homeowners and regulatory ...


Management Strategies In The Wildland-Urban Interface Of Southern California And Their Effect On Fire Behavior And Environmental Impacts, Christopher Dicus Jan 2006

Management Strategies In The Wildland-Urban Interface Of Southern California And Their Effect On Fire Behavior And Environmental Impacts, Christopher Dicus

Natural Resources Management and Environmental Sciences

This paper discusses varying management strategies in wildland-urban interface communities of southern California in terms of their effects on potential fire behavior and residual environmental impacts. A century of fire exclusion policies there and throughout the United States has led to immense fuel loading and declining ecosystem health, which coupled with a burgeoning population relocating to wildland areas, has annually heightened the threat of devastating wildfires. Successful management strategies must consider elements of suppression needs, community education, construction and development standards, and vegetation manipulation, each of which will vary dependant on the ecosystem and socioeconomic conditions of the area considered ...


Effects Of Lop And Scatter Slash Treatment On Potential Fire Behavior And Soil Erosion Following A Selection Harvest In A Coast Redwood Forest, Kyle W. Jacobson, Christopher Dicus Jan 2006

Effects Of Lop And Scatter Slash Treatment On Potential Fire Behavior And Soil Erosion Following A Selection Harvest In A Coast Redwood Forest, Kyle W. Jacobson, Christopher Dicus

Natural Resources Management and Environmental Sciences

Even though harvesting timber is one method of reducing fuel continuity and subsequent potential fire behavior, the residual slash can greatly increase the surface fuel loading and subsequent risk of wildfire on harvested sites. Fire behavior following silvicultural treatments to a stand can vary greatly, with both depth and loading playing a significant role (Nives 1989). Surface fuels and subsequent potential fire behavior has been shown to increase in the first year after harvest in coast redwood forests (Sequoia sempervirens (D. Don) Endl.) (Dicus 2003), which threatens not only natural resources but also structures in an ever-increasing wildland-urban interface. Alternatively ...


Effects Of Fuel Loading On Potential Fire Behavior And Soil Erosion In Coast Redwood Stands, Eric Just, Christopher Dicus Jan 2006

Effects Of Fuel Loading On Potential Fire Behavior And Soil Erosion In Coast Redwood Stands, Eric Just, Christopher Dicus

Natural Resources Management and Environmental Sciences

Commercial timber harvesting typically reduces aerial fuel loading and continuity, but can actually heighten fire activity through increased surface fuel loading (Agee 1997). Fuel depth and loading, which typically increase after harvest, play a significant role in fire intensity and rate of spread in redwood forests (Sequoia sempervirens) (D. Don.) Endl.) (Nives 1989), which are significant predictors of redwood mortality (Finney and Martin 1993). However, residual slash fuels may simultaneously reduce erosion, which may be of greater importance in some areas because they intercept rainfall and soil particles dispersed by overland flow (Fernandez et al. 2004). The relationship of surface ...
