The Castle Wilderness, part of the Crown of the Continent Ecosystem, one of the most diverse and beautiful areas in Canada, is 795 km2 of unprotected wildland, but is not safe for wildlife.
Plant communities range from fes cue grassland to alpine tundra.
Half of the 1600 vascular plant species mAlberta, including 162 rare species, can be found in the Castle Wilderness. This area provides essential habitat for grizzly bears, cougars and wolves. Between 1914 and 1921, the area was part of Waterton Lakes National Park, and was a Provincial Game Reserve until 1954. Many of these are service roads and pipelines for the 71 gas wells drill in the Castle since 1958. Every major valley in the Castle Wilderness has a road, disrupting wildlife and reducing their habitat.
