throughout Africa. Destinations Overview The Calgary zoo has many different exhibits in its 92 acres of land. Destination Africa Opened in 2003, the Destination Africa project was among the zoo's most ambitious expansions. The complex of four buildings includes the TransAlta Rainforest and the African Savannah. The TransAlta Rainforest occupies 2,900 square metres (31,000 square feet) and features a collection of African rainforest flora and fauna. The African Savannah building is home to hippos, Masai giraffes, red river hogs, and a baobab tree. A 340,000-litre (80,000-gallon) indoor pool for hippos offers view of the creatures underwater. In the warmer months, the doors lift to connect the building with the rest of the Savannah exhibit, home to Hartmann's mountain zebras, grey crowned cranes and ostriches. Many other animals of the grasslands, including African lions, also reside in the Savannah exhibit. In the TransAlta Rainforest, there are primates such as western lowland gorillas, eastern black-and-white colobus, and mandrills, and a number of reptiles including leopard tortoises, Malagasy tree boas, a panther chameleon and a pair of dwarf crocodiles, as well as an aviary containing various species of African birds. Land Of Lemurs In 2017, the Land of Lemurs was opened to the public, with 3 different species of lemurs residing within; the black-and-white ruffed lemur, the ring-tailed lemur, and the red-fronted lemur. Canadian Wilds The Canadian Wilds were built in the 1990s to house the majority of zoo's collection of North American birds and mammals. The area includes outdoor enclosures in three zones: the Aspen Woodlands, the Northern Forest, and the Rocky Mountains. Animals in the enclosures include dall sheep, river otters, caribou, bighorn sheep, mountain goats, grizzly bears, muskoxen, whooping cranes, black bears, cougars, wood bison, and grey wolves. Rocky Mountain Bird Aviary This aviary includes a barred owl, golden eagle, great grey owl, bald eagle, snowy owl, and rough-legged hawk. Dorothy Harvie Botanical Gardens and ENMAX Conservatory The outdoor gardens are among the zoo's most popular attractions and include the Dorothy Harvie Gardens. The zoo's sheltered location supports many marginally hardy plant species. The conservatory comprises the indoor component of the zoo's gardens. It includes a number of "themed" areas such as the tropical garden, the rainforest, the arid garden, and the butterfly garden. A number of animals including birds and invertebrates are housed in the conservatory. The ENMAX Conservatory was completely renovated in 2009 and features an increased emphasis
