Abstract
GLFC research to be showcased in national e-lecture series: A selection of research being undertaken by scientists at the Great Lakes Forestry Centre (GLFC) will be the focus of a fall 2010 series of national electronic lectures hosted by the Canadian Institute of Forestry.
Testing new methods for assessing forest resilience and sustainability in the boreal forest: Forest-dwelling birds are important indicators of a forest's ability to withstand ecological change. Measuring bird distribution and abundance in the vast boreal forest is a daunting task that ecologists have had to do in person in the field. New technologies are presenting opportunities to automate this task and reduce costs. Canadian Forest Service scientists in Ontario are striving to refine the timing and frequency of the recording of bird songs and to develop analysis techniques for automated interpretation of the recordings back in the laboratory.
More computing power leads to new risk modelling tools for managing alien invasive forest pests: Invasive alien forest pests, including insects, diseases and plants, have changed the forested and urban landscapes of North America over past centuries. Predicting the hot spots for such invasions can be challenging given the high degree of uncertainty related to pest introduction, spread and degree of damage. a recent collaboration between Dr. Denys Yemshanov of the Great Lakes Forestry Centre and scientist in the United States has led to the development of powerful modelling tools to address such uncertainty. The models, which factor in the element of uncertainty, will allow land manages to develop friendly versions of these models will facilitate more effective decision making by pest management agencies in the face of limited human and financial resources.
New field guide assists in prescribed burning for tallgrass prairie restoration: Up until 2009, prescribed burning operations to restore the endangered tallgrass prairie ecosystem of southern Ontario were guided by fire behaviour prediction models that had been developed using data from experimental burning projects in forests. A collaborative project was initiated in 2007 to examine the accuracy of these models and to evaluate several other fire spread models, and develop a rapid fuel load assessment method for this ecosystem type. The new models that resulted are more effective in predicting fire spread in this ecosystem, and are now being documented in the Field guide for estimating fire behaviour in the Ontario tallgrass prairie fuel type.
The Turkey Lakes Watershed: reflecting upon the first 30 years: The Turkey Lakes Watershed is a research site near Sault Ste. Marie that has provided valuable scientific information for the past 30 years. Initially focused on examining the impacts of acid rain on a forested ecosystem,the scope of the research has expanded to include studies of forest harvesting impacts, forest carbon budgets, climate change and others. Research is undertaken with a view to gaining a better understanding of whole ecosystem effects of various human-caused disturbances on this northern hardwood forest. Ongoing monitoring of the research area has created a continuous record of ecosystem status that will help answer the science questions of today and tomorrow and continues to influence policy.
