Slide19Mixedwood PlainsThis is the smallest ecozone covering only 9% of Canada’s total land area. More than 60% of the total Canadain population and is home 50% of Canada’s endangered species.
Slide20Mixedwood PlainsBorders three of the five Great Lakes and extends alond the St. Lawrence Seaway to Quebec City. Next door to its most important trading partner-USA, which is convenient for the transportation of people and goods.
Slide21Mixedwood Plains Climate, Soil,etc. Relatively warm and moderate climate. Mainly flat land with rich fertile soils to support agriculture and food- processing industries. Produce such as fruits, vegetables and wines.
Slide22Mixedwood Plains con’tThis region is called the Canadian Heartland and an Industrial Powerhouse , where two-thirds of the country’s goods are produced. Around the area of Lake Ontario ( Greater Golder Horseshoe) is a dense concentration of industries and commerce. The larger region is known as the Windsor- Quebec Corridor; industrial parks, heavy industry (oil refineries) and rows of hydroelectric power lines.
Slide23Mixwood Plains con’tTourism and recreation are important part of this regions diverse economy. Niagara Falls, Ontario Science Centre, CN Tower, Royal Ontario Museum and old Quebec City. Hockey, Baseball, Basketball, Football and Lacrosse.
Slide24Mixedwood Plains con’t100 people per square kilometre – ten times denser than anywhere else in Canada. Ontario has 12.8 million residents with 90% living in Mixedwood Plains. Quebec has 8 million with 80% living in Montreal, Quebec City and Trois- Rivieres.
Slide25Mixedwood PlainsArgriculture, logging and the growth of cities have completely changed this ecosystem. More than 90% of the original wetlands have been drained for farming and urban development. This ecosystem originally consisted of thick, green forest cover with a mix of coniferous trees (eastern pine, red pine and hemlock).
Slide26Mixedwood PlainsThis region also included abundance of deciduous (sugar maple, red oak, and white elm). Most species have disappeared with the exception of white-tailed deer, foxes, and grey and black squirrels. Some species have adapted including coyotes, raccoons, mice, and groundhogs. Living within cities (nuissance)
Slide27Mixedwood PlainsTurn to page 149 and do questions 1 & 2.
Slide28Montane Cordillera Montane Cordillera • • Most of this ecozone lies in British Columbia with about 10% in Alberta. • • Rows of mountains are separated by wide valleys, and a plateau , which is an area of elevated, flat land.
Slide29Montane Cordillera Montane Cordillera • Natural vegetation depends on its location on the mountains or in the valleys. • Windward (west) side of a mountain recieves orographic precipitation creating dense coniferous forest. • Alpine tundra is found on the top of the mountain where it is too cold and wind swept for tree to grow.
Slide31Montane Cordillera Montane Cordillera • Leeward (east) side of the mountain do not receive as much precipitation and are protected from the westerly winds. • Grasses and sagebrush grow in the valleys of these dry regions.
Slide32Montane Cordillera Montane Cordillera • The beauti of watersheds, mountains and forests provides an excellent opportunity for tourism and recreation. • Forestry is also an important industry in this region providing many jobs. • The soils is ideal for fruit farming and vineyards. • Coal deposits have resulted in many mines.
Slide33Montane Cordillera Montane Cordillera • Two major challenges: 1. Only 5% of the land is suitable for agriculture. 2. Urban growth, industrialization, and increasing tourism are causing increasing pressure on the fresh water supply of the ecozone.

A continental climate can be found in this region, dry with extreme range in temperature, winters are cold and summers are hot.

Slide42Protecting The Ecozones United Nations guidelines suggested each Country protect 12% of total land use. All people involved with the use and protection are called Stakeholders . Stewardships involve taking care of private land or donating land for protection.
