The Fauna of Saskatchewan include several diverse land and aquatic animal species. From the multiplicity of invertebrates and vertebrates, two have been chosen as symbols of Saskatchewan.〔 〕 Cenozoic vertebrate fossils reveal the geological evolution of the interior plains and its prehistoric biogeography.〔 〕 Today, Saskatchewan's ecosystems range from the sub-arctic tundra of the Canadian Shield in north Saskatchewan to aspen parkland, the Mid-Continental Canadian forests in the centre of the province and grassland prairie.〔 〕 Fauna inhabit areas unique to their own specific and varied breeding, foraging and nesting requirements.〔 〕 With a large land and water area, and small population density, the ecoregions of Saskatchewan provide important habitat for many animals, both endangered and not.〔 〕 Naturalists observing wildlife have enumerated shrinking and growing wildlife populations. They advocate programs and methods to preserve or re-introduce endangered species and identify programs of control for outbreaks of wildlife populations.〔 〕 A broad diversity of wildlife habitats are preserved as parks and reserves protecting the feeding and breeding grounds of protected and indigenous fauna of Saskatchewan.〔〔 ==Provincial symbols== The sharp-tailed grouse (''Pedioectes phasianellus jamesi'') was declared the symbol of Saskatchewan in 1945. As of 2001, the provincial animal is the white-tailed deer (''Odocoileus virginianus''). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fauna of Saskatchewan」の詳細全文を読む スポンサード リンク
