Royal antelope
A herbivore, the royal antelope prefers small quantities of fresh foliage and shoots; fruits and fungi may be taken occasionally. Though the antelope is considered to be nocturnal, zoologist Jonathan Kingdon holds that feeding occurs throughout the day, though some foraging may also be observed at night. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles. These features do not allow complete digestion of lignified growth. Individuals may often move into new locations foraging for fresh growth.
James Bernard Harkin
The pronghorn antelope was another large Canadian mammal believed to be on the verge of extinction. In 1910, the pronghorn antelope was moved from the Banff Paddock into Wood Buffalo National Park. Harkin believed the animal would benefit in a new protected park area. In March 1912, the park reported the presence of fourteen antelope. However, the effort was unsuccessful as the pronghorn antelope population decreased due to a lack of proper diet. In 1915, Harkin continued to play an essential role in antelope preservation near the village of Nemiskam, Alberta, where about 200 starving antelope were found in a rancher near the village of Foremost. The antelope were removed and sent to a reserved area of Maple Creek, where sufficient food and resources were available . On December 18, 1915, Minister William James Roche approved the formal reservation of seven square miles of land and established the Nemiskam National Antelope Reserve. In 1917, the American Permanent Wild Life Protection Fund recognized Canada as the first country to create a fenced preserve for antelope. In 2012, the pronghorn antelope can be found in southern Saskatchewan and Alberta.
