The most recent comprehensive range maps for trees in North America were produced in 1970 for the US Forest Service Atlas of U.S. Trees; it's available in GIS format. ECSONG is undertaking the task of bringing the Canadian portion of these maps up to date, concentrating on Ontario & Québec where we have members and contacts.
For each nut species, new data is added as points in a new GIS layer to keep our data independent of the USFS, and each point is labelled.
We invite submissions of new data from any reader to assist us in providing complete maps of all nut-bearing trees.
Added points: Dominion Arboretum, L'Orignal, John Adams, Morgan Arboretum, Montreal Botanic Gardens, Grimo Nut Nursery
Added points: Dolman Ridge, Aylmer, Baxter Conservation, Sawmill Creek, Lavant Twp., Burnstown Rd, Dominion Arboretum, Matheson Rd.
The historical range is problematic now that fungus has almost wiped the species out. Added points will be where stable populations exist due to hypovirulence.
