Results/Conclusions Vegetation quality (crude protein) was highest in areas that were recently burned and grazed (ca. 18%) throughout the growing season and decreased in areas with greater time since fire (ca. 4%). Vegetation quantity was lowest in recently burned areas and increased with time since fire. Attraction to burned areas is likely due to increased nutritional content and reduced biomass. High light environments were present in recently burned areas, and were maintained beyond the growing season. Total leaf area of A. gerardii was lowest in recently burned areas (ca. 8 cm2; maintained throughout the growing season) and increased with time since fire (ca. 80 cm2). In contrast, maximum photosynthesis of A. gerardii was highest in recently burned and grazed areas (ca. 50 µmol CO2 m-2 s-1) and decreased with time since fire (ca. 20 µmol CO2 m-2 s-1). A tradeoff in plant productivity appears, as leaf area is maximized with greater time since fire, but at the cost of reduced photosynthesis. These fine scale mechanisms are the result, but also contribute to, the broader scale interactions of fire and grazing. Fire grazing interactions are complex ecological processes, influencing many aspects (animal behavior, plant physiology, thermal environments, etc.) of the ecosystem.
