Conifer swamps occur in areas of seasonal flooding. Trees can be very dense or sparse; mats of sphagnum moss cover the ground. 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]
Planting trees in tropical climates with wet seasons has another advantage. In such a setting, trees grow more quickly (fixing more carbon) because they can grow year-round. Trees in tropical climates have, on average, larger, brighter, and more abundant leaves than non-tropical climates.
Lower temperatures were also recorded at the city’s Yangtze River Beach Park, where 45,000 trees and other vegetation sequester an estimated 724 tonnes of carbon per year.
Atmospheric rivers of the sort causing massive floods and mudslides in Canada's British Columbia are akin to a river in the sky, weather systems that carry up to 15 times the volume of the ...
Now a new threat from the storm has arrived Wednesday as the bomb cyclone’s winds wind down: It’s combining with an atmospheric river to unleash life-threatening flooding rainfall over parts ...
Coastal flooding is expected to increase in many areas of Canada due to global sea-level rise and local land subsidence or uplift. [30] The country's sea level is increasing between 1 and 4.5 mm per year. The areas that are going to have the biggest strike is southwest and southeastern Canada. [31]
A 2018 study found that trees grow faster due to increased carbon dioxide levels; however, the trees are also 8–12 percent lighter and denser since 1900. The authors note, "Even though a greater volume of wood is being produced today, it now contains less material than just a few decades ago."
