The Warm Fire burned in pinyon-juniper, ponderosa pine, and mixed-conifer forests at low to high severity on the Kaibab National Forest (KNF) from 8 June to 4 July 2006. The fire burned 15% of our Kaibab Plateau study area where we investigated the distribution, habitat, and demography of the northern goshawk (Accipiter gentilis) for 16 years (1991-2006). We also investigated the distribution, abundance, and habitats of eight goshawk prey species during 13 years (1994-2006) on 76 prey-census transects. Thirteen (11%) of 121 Kaibab goshawk territories were burned by high severity fire and 5 (4%) were burned by low severity fire. Eleven (15%) prey transects were burned in high severity fire and 3 (2%) were burned in low severity fire. We will investigate the effects of fire severity on the distribution, abundance, and habitats of this predator and its prey. Goshawk elusiveness makes them difficult to locate each year placing a premium on yearly continuity of monitoring. This, combined with a high likelihood for a large first-year fire effects on the goshawks food web, are compelling arguments for RAPID RESPONSE TASK 2 research. Objectives are to: (1) Develop regression models to assess the influences of fire severity (low and high) and no fire on nest survival and productivity of goshawks and the distribution and abundance of important goshawk prey; (2) quantify habitat changes (e.g., fuels reduction) from before to after low and high severity fire (fire severity class will be verified) to assess the effects of fire severity on wildlife habitat; (3) develop guidelines regarding the use of broadcast and fire-use fires that predict habitat suitability of low and high severity fires for species in the goshawk food web. This study will produce valuable scientific information that will quantify effects of two levels of fire severity on the habitats of goshawks and their prey species, and provide managers with information that elucidates the ecological consequences of fire severity, whether the result of wildland-fire use, prescribed fire, wildland fire on goshawks and their prey.
