In areas where elk browse heavily, repeated feeding can stunt young shoots and make it difficult for aspen stands to regenerate. According to the USDA, scientists designed a special fence that could help address this problem without excluding other wildlife. The researchers enclosed a one-hectare stand of quaking aspen with a fence that kept elk out while allowing deer, bears and other animals to pass through. Within a year, the protected aspen stems had gained 14.5 cm more height than those outside the enclosure. The findings demonstrated how a targeted approach to managing browsing pressure could help young trees grow while allowing other wildlife to continue using the habitat.
