Prairies Ecozone

-Three of the largest population concentrations are Calgary, Manitoba, and Saskatoon.

-Northern limit: About 54° N

-Western limit: About 116° W

-Southern limit: 49° N

-Eastern limit: About 96° W

-Bodies of water : North and South Saskatoon River

-Environmentally protected areas: Douglas Provincial Park, Grasslands National Park, and Buffalograss Ecological Reserve

-Land is mostly flat and fertile

-A few moraines that are composed of ponds and small lakes

-Many depressions called "Prairie Potholes"

-Other landforms include deep valleys and hummocky lands

-Land was flattened by glaciers

-Many layers of sedimentary rock beneath

-Clay soil dominates the Prairies Ecozone

-Clay soil blocks plant growth and the flow of nutrients and water

-Trees can't grow in clay soil

-Very southern

-Seasonal Temperature

-Low Altitude

-Yearly temperature range is about 38 °C.

-Total yearly precipitation is 348mm

-Approximately 177 days of growing season in a year

-Continental climate

-Most endangered vegetation status

-Many of the natural vegetation was destroyed due to farming

-Few trees

-Divided into 3 sub-regions: short-grass prairies, long-grass prairies, and parkland.

Aspen:

-Deciduous tree

-Grows up to 90 feet

-Very fragile and easily affected by numerous insects and diseases

-Can't live for more than 20 years

-Grayish bark with green leaves in summer and yellow leaves in fall

Spear Grass:

-Grows fast

-Can grow up to 1.5 meters in height

-Used for grazing

-Long and brown

-Bristles become hard after early summer

-Grows in open areas with stony soils

-Grows from October to March

-High biodiversity

-Supports many species

-Species include fishes, toads, lizards, and rattlesnakes

-Many endangered and extirpated species due to human development

-Peregrine falcon, and whooping crane are both endangered

-2nd largest population in Canada

-1/9 of Canada's population

-Major population centerse are Calgary, Edmonton, Saskatoon, Regina, and Winnipeg

-All those cities are built near rivers

-15% of the population live in rural areas

-Farming is the most important industry

-Because of mining, much of the wildlife has disappeared

-Crops include grain and pulses

-Production of fuel is 2nd most important industry

-Prairie Pacific Mining Corporation

-No particular project
