Index of Subjects David (and all). Interesting. I checked and a few copies are still available from used book sellers. I also looked up E.S. Richards and found that, in 1938, he was the "timber cruiser and appraiser" hired by the Federal District Commission to evaluate privately owned woodlots that would later be acquired - many by expropriation - to form Gatineau Park. He was also the first Gatineau Park Superintendent (Michael Christopher Lait, thesis, Carleton University, 2017). Further to the topic of woodlot management, last week, the Chronicle Herald published an article by Josh Noseworthy, director of conservation science for the Nature Conservancy of Canada, Atlantic region and lead author of NCC’s Acadian Forest Restoration Manual. I'll post the link below. The article linked to the "restoration manual" mentioned by Noseworthy -- I'll provide the link here as well. I downloaded it yesterday -- you have to answer a few brief questions first and then they email you an access link. I have been too busy this last few days, sawing up a large old Locust tree felled by Dorian, so have not had time to do more than peruse the manual, but it looks quite interesting. I see a number of familiar names listed as reviewers and contributors (Bob Bancroft, Alain Belliveau, and others), and many beautiful tree and forest photos by Alain as well. Worth a read, I think.
