Forest fires are extremely costly hazards in terms of lives, natural resources and infrastructures. In the last decades, the low predictability of ignition due to anthropogenic factors have increasingly put a strain on forestry agencies1 as well as on local economies. According to NOAA’s National...
In Canada, recent forest disturbance episodes such as insect outbreaks, forest fires, and drought have significant consequences on forest ecosystems while future climate change is expected to result in more severe impacts. These effects of climate change will impact the communities that depend on fore...
While we have been considering the causes and effects of forest fires, our horses and men have been struggling with the more material side of the question, and as the imagination leaps lightly over all sorts of obstacles, let us now overtake them as they arrive at a good camping place abou...
Name three human causes of global warming. What is albedo effect? What are the main greenhouse gases and explain how they affect the Earth. Describe the relationship between the greenhouse effect and global climate change. How deforestation of tropical rainforests play a role in excess CO_...
Dead trees with signs of Siricidae and dead from other causes were also quantified, and in some P. resinosa stands, levels were greater in magnitude than S. noctilio losses. Data from this study suggest that silvicultural treatments should be a key component of integrated pest management plans...
Prior to this shift, the assumptions held that old-growth forests were almost absent in boreal land- scapes because of relatively frequent forest fires and that some boreal forest stands did not remain stable in an old-growth phase, but they rather became open peatlands in the absence of ...
The main event was publishing The Royal Canadian Air Force: 100 Years of Service, one of Canada’s loveliest books this century – you name the subject. Having begun this project in 2018, things sailed along, then got to be touch-and-go towards the end. First, so much material was ...
Moderate-severity disturbances occurred mainly during previously identified SBW outbreaks in the southern portion of the region (Morin and Laprise1990; Krause1997). In the eastern Canadian boreal forest, SBW is the main agent of secondary disturbance (Morin et al.2009; Shorohova et al.2011). Pre...
upright main-stem axes were constructed by vigorous, mostly distal shoots that remained more or less upright. The pendulous habit was largely the result of lateral shoots that were initially upright or semi-pendulous, drooping under their own weight to become pendulous. The pendulous habit was exac...
This study investigated the hydrology of Castle River watershed in the southern Albertan Rocky Mountains with particular focus on climate change induced alterations and the impacts of forest fires on streamflow. The initially raised questions and objectives could mainly be achieved. The declining runoff ...
