Forest insects: agents of disturbance, indicators of health

Come join Dr. Don Henne, entomologist and Assistant Professor, Faculty of Natural Resources Management at Lakehead University as he guides us into the world of forest insects.  Insects are found almost everywhere, and they play important roles in numerous ecological processes. They are, so to speak, the little things that run the world. However, insect populations are collapsing all over the planet and we don't know why. This loss of insect diversity and abundance threatens the survival of plants, animals, and humanity. This talk will be an exploration of insects as natural disturbance agents, their roles in keeping ecosystems healthy, and the recent global decline of insect populations. A brief overview of insects that are active during the winter will also be presented.

This is our last general meeting before the summer and we will hear from two speakers who will share information that enhance our understanding of the local environment.

Permafrost, here! 

About 50% of Canada has permafrost, and most of it is in the Arctic and Subarctic. In Ontario, the permafrost we know can be found in the Hudson Bay Lowlands, starting some some 400 kilometres north of Thunder Bay. However, recent work in Ouimet Canyon and Ruby Lake Provincial Parks has shown that permafrost exists in some particular environments just a few kilometres from Lake Superior. Saille Bishop-Legowski, MSc. in Geography at Carleton University, will talk about what she found and how special ground conditions can support permafrost so far south.


Invasive Plant Species: a Thunder Bay Perspective. 

Melisa Davidson, Invasive Species Intern with Eco-superior is working on a strategy to address invasive species in the Lakehead.  Last fall, Thunder Bay Field Naturalists co-sponsored her participation in a conference addressing invasive species. She will briefly share with us some of the main messages, and what she learned about invasive species and control strategies in Canada.  She will identify some of the highest profile invasive species in the Thunder Bay area but emphasize invasive plant species we should be aware of and concerned about around Thunder Bay.  There will also be a brief discussion of what is proposed in Thunder Bay to control invasive species and how you can help.


Continue to check back on this page as talks are arranged for next season starting in September.
