Eastern hemlock speaking series

crw_2840Many of the oldest, most ecologically intact forests in Ontario are dominated by hemlock… and often they are much closer to home than you’d imagine. Join Michael Henry, to learn about the history, ecology, and future of eastern hemlock forests. Presentations will also explore the larger problem of invasive forest pests, and how we can remain hopeful about the future of our forests in the face of disappearing tree species.

Michael Henry is the lead author of Ontario’s old-growth forests, and is an ecologist and educator with Ancient Forest Exploration and Research. He began studying the old-growth pine forests of central Ontario in the mid-1990’s, and has spent time studying, writing and speaking about old-growth forests and their conservation since then. Recently he is involved in projects to conserve eastern hemlock forests, to locate old trees on the landscape, and to study old-growth forest in the Toronto ravines.

Jackson Creek Old-Growth Forest (Hosted by the Peterborough Field Naturalists)

Learn about the Jackson Creek urban old-growth forest. Trees in this forest reach over 250 years old, pre-dating the original settlement of the Town of Scott’s Plains, which is now Peterborough. The presentation will also discuss how we can recognize old trees, stewardship of urban old-growth forests, and the threat of invasive species including hemlock woolly adelgid.

Tree Trouble

Trees are a dominant feature of the natural landscape. Unfortunately, one by one Ontario’s tree species are being assaulted by a range of fungal blights, diseases, and introduced insect pests altering the species makeup of our forests. Chestnut Blight, Dutch Elm Disease and Emerald Ash Borer come to mind. Join North Durham Nature’s James Kamstra and Mike Henry, a forest ecologist with the Ancient Forest Exploration and Research Group, for this presentation.

James will look at the origins, spread and implications of the various pathogens, and warn us of new ones on the horizon. Mike will be talking about the Eastern Hemlock project he is leading involving the documentation of the spread of the Hemlock Wooly Adelgid, an aphid like insect that has had a large impact on the hemlock forest in the Appalachian Mountains, and was recently discovered in Ontario.

Please meet at 7 p.m. at the Scugog Memorial Library (231 Water Street, Port Perry). Everyone is welcome! A donation of $5 is appreciated from non-members. For more information, please visit our website at www.northdurhmnature.com or “Like” us on Facebook!
