The fauna of Canada is considered to be diverse across Canada, ranging from lush forests of British Columbia, to the prairies of Western Canada, to the tundra of the Northern Canada. With a large land mass, and small population density, the wildlands of Canada provide important habitat for many animals, both endangered and not. Canada is home to approximately 70 000 known species of plants and animals - and perhaps many more that have yet to be discovered.
The Niagara Falls are renowned both for their beauty and as a valuable source of hydroelectric power. Managing the balance between recreational, commercial, and industrial uses has been a challenge for the stewards of the falls since the 1800s.
The Snowy Owl (Bubo scandiacus) is a large owl of the typical owlfamily Strigidae. The Snowy Owl was first classified in 1758 by Carolus Linnaeus, the Swedish naturalist who developed binomial nomenclature to classify and organize plants and animals. The bird is also known in North America as the Arctic Owl or the Great White Owl.
Until recently, it was regarded as the sole member of a distinct genus, as Nyctea scandiaca, but mtDNAcytochrome bsequence data (Olsen et al. 2002) shows that it is very closely related to the horned owls in the genus Bubo. The Snowy Owl is the official bird of Quebec. This species of owl nests on the ground, building a scrape on top of a mound or boulder. A site with good visibility, ready access to hunting areas, and a lack of snow is chosen. Gravel bars and abandoned eagle nests may be used. Breeding occurs in May, and depending on the amount of prey available, clutch sizes range from 5 to 14 eggs, which are laid singly, approximately every other day over the course of several days.
Terra Nova's landscape is typical of the northeast coast of Newfoundland, with remnants of the Appalachian Mountains contributing to widely varied and rugged topography throughout the region. The park's seacoast consists of several rocky "fingers" jutting into Bonavista Bay along an area stretching from just north of Port Blandford to the vicinity of Glovertown. The coastline varies from cliffs and exposed headlands to sheltered inlets and coves, contributing to Newfoundland's prime recreational boating area.
Inland areas consist of rolling forested hills, exposed rock faces, and bogs, ponds and wetlands. Wildlife protected by the park range from small to large land mammals, migratory birds, and various marine life. Terra Nova also protects an area containing remnants of the Beothuk Nation, as well as many of the early pioneer European settlements in the region.
Populus tremuloides is a deciduous tree native to cooler areas of North America. The species is referred to Quaking Aspen, Trembling Aspen, and Quakies, names deriving from its leaves which flutter in the breeze. The tree-like plant has tall trunks, up to 25 metres, with smooth pale bark, scarred with black. The glossy green leaves, dull beneath, become golden to yellow, rarely red, in Autumn. A tall, fast growing tree, usually 20–25 metres (66–82 ft) at maturity, with a trunk 20–80 centimetres (7.9–31 in) in diameter; records are 36.5 meters (120 ft) in height and 1.37 metres (4.5 ft) in diameter. The bark is relatively smooth greenish-white to gray and is marked by thick black horizontal scars and prominent black knots.
