The new park area is estimated to be the home of around 500 grizzly bears, two herds of woodland caribou, as well as species of alpine sheep and goats and other species. The new boundary will include the highest mountains and largest ice fields in the Northwest Territories. With the expansion of the park there have been several added designated landing sites. Because most access to the park is done by aircraft and air access is restricted in the park, there are set places aircraft can land. Before the expansion these were limited to Virginia Falls and Rabbitkettle Lake. Now there are five more: the Bunny Bar, Island Lake, Honeymoon Lake, Glacier Lake, and Seaplane Lake. However, only Virginia Falls and Glacier Lake are designated for day use visitation, meaning all other sites require visitors to stay overnight in the park.
