Establishment Histories and Structural Development of Mature and Early Old-Growth Douglas-fir Forests of Western Washington and Oregon
Regeneration of tree populations following stand-replacing wildfires is an important process in the multi-century development of Douglas-fir<&mdash> --</&mdash>western hemlock forests. Temporal patterns of tree establishment in naturally regenerated, mid-aged (100 to 350 years) Douglas-fir-dominated forests have received ...
Urbanization alters the influence of weather and primary productivity on avian populations in the Seattle metropolitan area
Two novel, abiotic challenges that affect primary productivity, and the biodiversity dependent upon it, are urbanization and climate change. Increased levels of urbanization cause an inversely proportional decrease in primary productivity, while climate change promises concurrent changes in temperature and precipitation. ...
Quantifying vertical and horizontal stand structure using terrestrial LiDAR in Pacific Northwest forests
Abstract Quantifying vertical and horizontal stand structure using terrestrial LiDAR in Pacific Northwest forests Alexandra Kazakova Chair of Supervisory Committee: Dr. L. Monika Moskal School of Environmental and Forest Science Stand level spatial distribution is a fundamental part of forest structure that influences many ...
Challenges and Opportunities for the Development of a Sustainable Forest Sector in the Russian Far East
Twenty-three percent of global forests are contained within the Russian Federation's nine time zones, which is more than the combined forest area of Canada and Brazil. Despite the fact that Russia contains the largest area of natural forests in the world, its current share in the trade of world forest products is below 4 ...
Very large wildfires in the western contiguous United States: probabilistic models for historical and future conditions
Wildfires, especially the largest ones, can have lasting ecological and social effects both directly on the landscape and indirectly on the atmosphere and climate. Both climate and fire regimes are expected to change into the future while air quality, the composition of the atmosphere, continues to be regulated. It is necessary ...
