Fire and Ecosystems
The majority of U.S. forests and grasslands are adapted to fire. Past management actions such as grazing, introduction of non-native species, and organized fire suppression, have drastically altered historical fire regimes. Climate change and increasing human expansion into wildlands are further exacerbating changes to vegetation and fuels from historical conditions. Changes in vegetation and fuels patterns, coupled with climate change, also affect biotic disturbances that interact with wildland fire. These interactions and stresses are changing contemporary fire regimes, degrading ecosystem resilience and altering fuel hazard. Knowledge of fire effects and ecology in fire-dependent ecosystems is essential to develop fuel-related products, treatment alternatives, restoration strategies, and accurate forecasting of future conditions.
