Abstract: Existing road networks are currently considered major contributors to ecosystem fragmentation and habitat degradation. Methods used for road maintenance and construction often further deteriorate and disturb surrounding habitats. Not only can roads act as barriers to existing plant and animal species, but they can also augment the infiltration and movement of predators, parasites and exotic species. Roads also increase the negative effects of human access to natural areas. In relation to interior habitat, roads increase the amount of edge habitat in a given community. This increase in edge area has abiotic and biotic implications that are detrimental to ecosystem functioning. The effects of roads are often a serious concern for biological reserves. Yet, despite its role as a natural reserve area, UMBS has never embarked on a study to determine the effects of its own extensive two-track road network. The purpose of this investigative analysis is to quantify road use on UMBS property and to provide a management proposal with recommendations for closure of roads to minimize the impacts of motorized vehicle use.
