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.

A Century of Change in a Ponderosa Pine Forest
1909-present
Living things change constantly, as do communities of living things. In a forest, where individual trees can live for centuries and new plants replace old plants, it is not easy to visualize the changes that occur over time. This photoseries documents changes in a ponderosa pine forest from 1909 to 2015. Download high-resolution photos here. See…
