Monitoring Fire Effects and Severity in the Arctic Network of National Parklands

Barnes J. Monitoring Fire Effects and Severity in the Arctic Network of National Parklands. 2010. National Park Service

Current and future climatic changes will impact the occurrence, extent, and severity of fires in the Arctic Network and will have cascading effects on other ecosystem processes. Fire can exert strong landscape scale effects on vegetation composition and distribution, permafrost dynamics, nutrient cycling, carbon gain or loss, and primary productivity. Wildland fire is one of the largest natural disturbance processes in the boreal and tundra ecosystems of the Arctic Network. Fire affects all of the parks within ARCN; in the past 50 yrs over 1 million acres have burned in the network. Fire influences not only vegetation succession and distribution, but also wildlife habitat, soil parameters (e.g. permafrost and nutrient cycling), hydrology, water quality and air quality. In addition, the natural fire regime (fire frequency, fire extent, and severity) and secondary fire effects are likely to respond to local and global climate changes (Rupp et al. 2000; Goetz et al. 2005). Baseline monitoring of fire parameters such as the number of fires, fire extent and burn severity will provide explanatory variables for ecological changes detected through the I&M program, while long term monitoring of fire effects on vegetation will provide a foundation to elucidate the complex relationship between fire and the landscape.
