Use of Remote Sensing Techniques to Determine the Effects of Grazing on Vegetation Cover and Dune Elevation at Assateague Island National Seashore: Impact of Horses
De Stoppelaire G, Gillespie T, Brock J, Tobin G. 2004. Use of Remote Sensing Techniques to Determine the Effects of Grazing on Vegetation Cover and Dune Elevation at Assateague Island National Seashore: Impact of Horses. Environmental Management. 34(5):642-649
The effects of grazing by feral horses on vegetation and dune topography at Assateague Island National Seashore were investigated using colorinfrared imagery, lidar surveys, and field measurements. The findings suggest that unless the size of the feral horse population is reduced, grazing will continue to foster unnaturally high rates of dune erosion into the future.
