The addition of woody debris to streams is a common restoration practice. Woody debris dams were added to four streams at Fort Benning Military Installation in 2003 to mitigate the impacts of military training activities on stream ecosystems. The short-term (3 y) and long-term (14 y) effects of these woody debris dams on ecosystem processes and community structure were evaluated. There were several changes to stream ecosystems after the woody debris additions including increased water residence times, primary production rates, ecosystem respiration rates, rates of nitrogen uptake, and retention of organic matter, as well as changes to macroinvertebrate communities. The woody debris dams were still in place 14 years later, and their long-term effects on the streams’ ecosystems are currently being evaluated.
