CUTTING TREES TO GROW FROGS: LONGLEAF FOREST RESTORATION INCREASES GEOGRAPHICALLY ISOLATED WETLAND (GIW) HYDROPERIOD IN SOUTHWESTERN GA USA

Geographically isolated wetlands (GIWs) are known as “hotspots” for biodiversity and other ecosystem services. Regular cycles of inundation and drying makes hydrology a primary controlling variable for sustaining GIW functions. Many GIWs are degraded and little work has focused on upland management to sustain or improve GIW structure and function. We present a study of longleaf forest restoration, by hardwood removal, on wetland hydroperiod over 10 years. Hardwoods were removed or deadened in a GIW catchment resulting in a 37% reduction. The effects on GIW hydrology were assessed using pre- and post-removal water levels, water yields (WYe), and standardized recession rates (RRstd). Hardwood removal increased WYe and decreased RRstd resulting in greater water availability reflected by water levels. Removal affected both the ascending and recessing limbs of hydroperiods, substantially increasing duration of ponded water. We show that forest management can enhance conditions in GIWS. Our study was limited in scope but conducted in a realistic operational setting. The results have implications at both the local scale, i.e., managing critical aquatic habitat for wildlife populations, and at a regional scale, i.e., providing support for landscape connectivity and water yields.
