Effects of Construction of the Digital Multipurpose Range Complex (DMPRC) on Riparian and Stream Ecosystems at Fort Benning, Georgia. Addendum

The goal of this project was to assess the effects of construction of the construction of the Digital Multipurpose Range Complex (DMPRC) on riparian and stream ecosystems at Fort Benning. Assessment of DMPRC impacts involved application of a number of the measurements and approaches used to identify military training impacts on riparian and stream ecosystems, with particular emphasis on measurements that proved to be good indicators of disturbance impacts in the ongoing study. These included measures of impacts on riparian vegetation and soil processes, stream hydrology and water quality, and stream biota and their habitat. Because Bonham Creek and Sally Branch were moderately disturbed prior to DMPRC construction, construction effects on these streams were likely not as great as would be observed in more undisturbed streams. Implementation of the DMPRC may offer an opportunity to improve biological conditions in Bonham Creek and Sally Branch if sediment delivery to these streams is reduced by more effective erosion controls.
