Fire is a natural and necessary component of some ecosystems and not others. In many regions of the country, it's a management tool used to shift the structure, species, composition and chemistry of an ecosystem to a desired condition. Some predictions suggest that the continued alteration of the land combined with climate change will change the timing, frequency and intensity of fires throughout the country. These predictions underscore the importance of understanding the impacts of fire characteristics on potentially sensitive species. It is against this backdrop that ARMI scientists study the impacts of fires on amphibian communities.

strategies, and then projected the mean risk of fires destroying structures and the area and configuration of important habitat types in San Diego County, California, USA. We found clear differences in both fire risk projections and biodiversity impacts based on the way conservation lands are prioritized for selection, but these differences were split between two distinct groupings. If no conservation lands were purchased, or if purchases were prioritized based on cost or likelihood of development, both the projected fire risk and biodiversity impacts were much higher than if conservation lands were purchased in areas with high fire hazard or high species richness. Thus, conserving land focused on either of the two objectives resulted in nearly equivalent mutual benefits for both. These benefits not only resulted from preventing development in sensitive areas, but they were also due to the different housing patterns and arrangements that occurred as development was displaced from those areas. Although biodiversity conflicts may still arise using other fire management strategies, this study shows that mutual objectives can be attained through land-use planning in this region. These results likely generalize to any place where high species richness overlaps with hazardous wildland vegetation.
