Re: Effects of uneven-aged harvest methods on soil properties.
Last year, I attended a very interesting lecture by Henry A. Froehlich,
Professor Emeritus of Oregon State University at the Southern Interior
Silviculture Committee winter workshop in Penticton, B.C. He discussed the
effects of frequent re-entry with heavy equipment and described a large-scale
experiment he conducted in Oregon to test skid trail design and treatment to
reduce soil damage.
He gave his address as: Forest Engineering Department
