Large wildfires can have dramatic watershed effects, including sedimentation of aquatic habitat that have the potential to impact stream species such as fish and frogs. In arid systems it may take years, even decades, for sediments to wash out from downstream areas. This talk will present an overview of the long-term interaction between wildfires and aquatic species in Arizona, with a particular focus on the lowland leopard frog in Saguaro National Park's Rincon Mountain District. We have been monitoring leopard frog populations, sediment, and water availability since 1996, including in streams where a high percentage of the watershed burned in 1999 and 2003 as well as streams where no fires occurred. The talk will also discuss pre- and post-fire management options for fire and aquatic frogs and other species. This webinar was presented by Don Swann from Saguaro National Park. It originally aired on June 19, 2013 and was hosted by the Southwest Fire Science Consortium.
