Black spruce (Picea mariana) and tamarack (Larix laricina) are the predominant tree species. Where the soil is not saturated year round grows northern white cedar (Thuja occidentalis).
Afforestation can also improve the local climate through increased rainfall and by being a barrier against high winds. The additional trees can also prevent or reduce topsoil erosion (from water and wind), floods and landslides. Finally, additional trees can be a habitat for wildlife, and provide employment and wood products. [2]
Environmental issues in Canada include impacts of climate change, air and water pollution, mining, logging, and the degradation of natural habitats.As one of the world's significant emitters of greenhouse gasses, [1] Canada has the potential to make contributions to curbing climate change with its environmental policies and conservation efforts.

[5] Canadian wetlands are predominantly located within the Boreal Shield which accounts for 25% of the existing wetland ...

It is typically divided into three classes: River flooding, which relates to rivers rising outside their normal banks; flash flooding, which is the process where a landscape, often in urban and arid environments, is subjected to rapid floods; [64] and coastal flooding, which can be caused by strong winds from tropical or non-tropical cyclones.
