One year after the colossal Bighorn Fire burned 120,000 acres in Tucson’s Santa Catalina Mountains, ecosystems are recovering. In these ecosystems, springs are a critical feature of the post-burn landscape and provide water for wildlife and opportunities for regrowth of plants.

Fire can be beneficial, especially for plants that have evolved to reproduce when there is a fire. But they can also be problematic for some ecosystems. For instance, some of the potential impacts of fire on springs include a concern that the source of the spring might get buried by landslides or debris, that the water quality might change, or that there could be a loss of important and rare flora / fauna species.

We don’t yet know how all the springs in the Santa Catalinas have been affected by the Bighorn Fire. In this image from August 22, 2021, you can see regrowth of green plants in the area of Maverick Spring, a water source located on the north side of the Santa Catalinas. Plants are growing back faster around the spring than in other areas in the photo, and this site remains important for local wildlife.
