Title: Ecosystem Responses to a High-Severity Wildfire: A Serendipitous Opportunity to Enhance the Fire/Fire Surrogate Study

Project Proposal Abstract: Southwest ponderosa pine ecosystems have garnered great attention due to fuel conditions that increase the lilcelihood of large-scale wildfires with severe fire behavior. The fire season of 2002 demonstrated these extreme fuel load conditions with the largest fires in Southwest history. National programs to reduce the extreme fuel loads that create the potential for these wildfires is underway, yet research to address ecological issues surrounding fuels reductio programs is lacking. One such program to address these issues is the Fire/Fire Surrogate Program (FFS) currently funded under the Joint Fire Science Program. One FFS location on the Jemez District of the Santa Fe National Forest experienced a wildfire (Lake Fire Complex 08/26/02 to 09/01/02)) that consumed one complete replicate block that was part of the FFS project, The loss of this site will require a replacement replicate block, but provides a unique opportunity to investigate wildfire effects on vegetation, soil, and associated microbial populations. Pre-treatment sampling was completed prior to the wildfire, which allows a return to the exact sites to investigate immediate post-wildfire effects. Previous wildfire investigations do notcontain pre-fire data, but typically contrast unburned areas to burned areas to imply fire effects These contrasts come from spatially different sites with little or no preexisting data. This rare opportunity will allow measurement of direct effects on vegetation, soil properties and microbial populations as affeated by high-severity wildfire. These data will further extend the ability of the FFS project in Southwestern ponderosa pine ecosystems to predict ecological consequences of fuei reduction programs as contrasted against ecological consequences of large-scale wildfire.
