Abstract: In this study we investigate the effects of livestock grazing on fire regimes in northern New Mexico. We accomplish this by reconstructing and comparing multicentury fire histories of ponderosa pine forests in areas with different grazing histories. Contrasting fire histories in these areas reveal the importance of land use history in the interpretation of pre-settlement fire regimes. The current structure and functioning of these ecosystems are intimately linked to past fire regimes. Consequently, knowledge of grazing practices and their potential effects on past fire regimes is important for interpreting, understanding and managing modern forests.
