“Changes in our natural world” with an Ontario Parks conservation ecologist
There is an opportunity to hear about conservation issues, past, present and future from a real ‘grass roots’ biologist at the next Mississippi Valley Field Naturalist meeting to be held Thursday evening April 20 in Almonte. The presentation will be given by Dr.William Crins, Senior Conservation Ecologist in the Planning and Research Section of Ontario Parks, at the Ministry of Natural Resources in Peterborough. A botanist by training, Bill has devoted his career to the study of living things, specializing in the evolution and ecology of important grasses and sedges. Several species new to science, including the juniper sedge Carex juniperorum Catling, Reznicek & Crins, bear his name.
As a ‘budding’ biologist in the early 70’s Dr. Crins worked summers at Algonquin Park as an interpretive naturalist and later conducted biological inventories and assessments used to develop the Nature Reserve Zone system in the park. Following graduate studies at the University of Toronto, Dr. Crins did research at UBC and the New York State Museum in Albany. As senior ecologist with Ontario Parks, he now applies his knowledge of conservation and biodiversity issues to projects such as the Ecological Land Classification system for Ontario and the development of old growth forest policy, as well as contributing to detailed inventory of Ontario’s habitat resources and Species at Risk habitat mapping guidelines.
Dr. Crins says that his presentation on Thursday “will illustrate some of the changes in flora and fauna that have occurred during the past century, and will speculate on some of the changes that may occur in the future.” What effects have development and the intensification and then abandonment of agriculture had on species and ecosystems? What have been the effects of accidental introduction of exotic species, changes in forest management practices, or changes in land use patterns? Potential impacts of climate change on species distribution and ecosystem composition will also be discussed.
The presentation, “Changes in the Flora and Fauna of Southeastern Ontario: Past, Present, and Future” is the last in MVFN’s series “Change in our Natural World” and takes place Thursday April 20th at 7:30 pm at the Almonte United Church on Elgin St. Program Chair Tine Kuiper will host the evening, and refreshments will be offered. All are welcome. A non-member fee of $5 applies (for those over 16) or MVFN memberships are available. For further information visit www.mvfn.ca or contact Pauline Donaldson at 256-9399.
