Document Summary
Much of the vegetation we see today in canada is not natural. Instead, it has been introduced through agriculture and human activity. Forest: deciduous forests are composed of trees that lose their leaves each winter. Ex: broadleaf forest and carolinian forest (southern ontario: coniferous forests are composed of evergreen trees. Grassland: these are found in relatively dry areas. The size of the grass varies with moisture content: grasslands in canada are only found in the prairie provinces. Xerophyte: a plant that has adapted to low amounts of water. Tundra: these small plants survive in harsh climates. They reproduce by runners (offshoot of the main plant): they are found in arctic and alpine areas. Tundra plants have shallow root systems due to the permafrost environment. The leaves of the plants are waxy in order to reduce moisture loss. Krumholz: a plant that grows in a sideways formation because harsh dry winds desiccate the upper part of the plant.
