The climatology of Vancouver applies to the entire Greater Vancouver region and not just to the City of Vancouver itself. While Vancouver's coastal location serves to moderate its temperatures, sea breezes and mountainous terrain make Greater Vancouver a region of microclimates, with local variations in weather sometimes being more exaggerated than those experienced in other coastal areas.
I scanned the trees and saw that a maple tree had "exploded". The explosion caused a big crack in the tree about three feet high. When a winter wind stirs the frozen trees, they sometimes appear to burst vertically. When it was 40 degrees below zero at night, I lay awake and listened to the trees explode. That's a true wilderness thermometer!
Another example will be that trees in surface fire regimes tend to have epicormic buds rather than basal buds. On the other hand, plants can also alter fire regimes. Oaks, for example, produce a litter layer which slows down the fire spread while pines create a flammable duff layer which increases fire spread. [6]
The province British Columbia in Canada is known for its high biodiversity with over 185 wildlife vertebrate, 171 bird species, and a variety of conifer and deciduous trees. [16] In forestry management, it is important to recognize the cumulative effects of habitat and environmental changes that have the potential to threaten BC forests.
The idea of oil well and oil reserve smoke pluming into the stratosphere serving as a main contributor to the soot of a nuclear winter was a central idea of the early climatology papers on the hypothesis; they were considered more of a possible contributor than smoke from cities, as the smoke from oil has a higher ratio of black soot, thus ...
[35] [36] [37] Moreover, trees within the southern limit of their range may begin to show declines in growth. [38] Drier conditions are also leading to a shift from conifers to aspen in more fire and drought-prone areas. [34] Climate change creates more fire-prone conditions in the Boreal forest of Canada. [39]
Mean average temperature usually ranges from 0 °C (32 °F) to 4 °C (39 °F), and even in summer the average temperature does not exceed 10 °C (50 °F). The zone sees heavy precipitation, usually in the form of snow. [3] Tree species are rarely found in this zone, and when they do grow, they take the low, sprawling Krummholz form. Shrubs are ...
Luckily, plans to improve management and plant trees on cleared land are in place. (Farjon & Page 1999) Though the marbled murrelet is still considered abundant, its population has undergone a rapid decline, principally because the old-growth forests in which they breed are subject to logging (Piatt et al. 2006). Current estimates are nearly ...
