The Rural Voice, 1998-10, Page 30Maximizing your woodlot assets Think of each tree as a share in a company, West Virginian forester tells Ontario woodlot owners By Keith Roulston ndividual trees in a woodlot are assets and you can improve your rate of return on those assets by proper management. That was the message brought to Ontario woodlot owners attending the Provincial Agroforestry Conference in Woodstock, September 11 by Gary Millar a manager of the 5,000 -acre Fernow Forest for the U.S. Department of Agriculture Forest Service in West Virginia. Trees are like shares in different companies: sugar maple is increasing at one rate, oak is increasing at another value, Millar said. Management decisions can increase that rate of return. There is a penalty to pay if you withdraw your investment ,too early. If you cut the tree at it's optimum size, you will get the most return on your investment. The rate of return (of the growth of the tree) may have been so high at the time that you cut the tree that in another few years you might have doubled your return on investment. If you let someone talk you into cutting the tree too soon, you will be the one to lose. In his area of the Appalachian Mountains, Millar said, too often the woods are ignored "until we need a new pick-up or we have to send our kid to college then we go out and we 26 THE RURAL VOICE cut wood from out woodlot. That's not what I call management — that's more or less withdrawing from the bank." Forests can be managed, he said. There are things that can be done to make them more productive and produce more value. Value is tied to the kinds of trees growing in the woodlot and whatever we can do to improve the quality of species, bring a better return for the management. Species composition is a long- term project, he said. If you just cut trees and leave the bush, you are creating environmental conditions that will affect the kinds of trees that will grow over the following years. "We may not be around and perhaps our children may not when those trees are harvested but we have had an influence in the way that we have caused disturbances in that forest." In Ontario, stumpage prices range from $1,200 per thousand board feet for maple, through $1,000 to black cherry to $150 for beech or $100 for poplar. It means that the kind of tree that grows has a great effect on the revenue generated from the same space. "If you have a stand that starts with 400 trees per acre at age 10, and you have many, many different species, you want to work for the high value species. You want the Your woodlot is a valuable part of the farm and a little care can increase its value, speakers say. limited growing space to be allocated to the trees you choose." Think of a forest as a given amount of growing space, Millar said. This space is three-dimensional, below the ground and in the air. There is competition for light, water and nutrients. You can influence which trees grow in a young stand by giving the growing space to the most valuable trees. Showing slides of an example of this kind of management, Millar said there was a double effect of the thinning. The space freed up went both to the crop tree they selected for growth and to the regeneration of younger trees of valuable species. "All we did was influence this stand by one small disturbance at the proper time," he said. "Regeneration is a long term investment but we can do things that don't cost a lot that can influence species composition for many, many years just by understanding the biology of the species." Some species are very tolerant to shade and can produce seedlings and grow to saplings under dense tree canopies but others like white ash, white birch and black cherry, need full sunlight early in their development. If you leave partial shade you are discriminating against these shade -intolerant species, he said. Only a few species can regenerate from seed stored in the forest floor, he said. For other species, if you don't have advance seedlings already present, when you remove the canopy the species that don't need shade are going to germinate and
