Selectively clear-cut forest patches on the Columbia River. The forested area in question is 85% conifer and mixed deciduous hardwood stands covering steep slopes and some inaccessible back country canyons and mountain meadows. The area covered in aging trees includes Douglas Fir, Red Fir, Yew, Oregon Ash, Big Leaf Maple, Red Cedar, Sycamore, Sitka Spruce, Engleman Spruce, and other hardwoods. A large portion of the lands bordering the National Forest have been logged and replanted in immature lodgepole or ponderosa pine and Douglas fir. This has created a long and sinuous ecotone within the National Forest of mixed soft & hardwood conifers. The request of the citizen's advisory group would log the ecotone, an accessible swath of trees between two clusters of 500 - 1000 year old Spruce, Cedar, Yew or Fir trees, and clear an entire bank of the longest tributary stream in the National Forest.

products are derived from these forested lands. In Ecologically speaking the "growth of the conifers in 100 - 1000 year old forests depends on a mutualistic relationship between tree roots and a class of fungi, known as mycorrhizae, that infect their roots. Unable to carry out photosynthesis, these fungi attach themselves to the roots to obtain the sugars they need. The mycorrhizae absorb water, soil nutrients and oxygen, passing these on to the trees. Antibiotic compounds in the fungi protect the tree from root pathogens and act as a protective sheath around the roots to bar parasites. The fungi produce chemicals that speed up the growth of new root hairs and tips. These two mutualistic partners, the trees and their fungi are, in turn, dependent upon symbiotic relationships with a number of small forest rodents such as squirrels, voles, and mice. These creatures feed on the fleshy collection of fungal spores -- called truffles. Once consumed the spores remain undigested, passing back into the soil to grow another generation of root fungus." Without the decaying logs & snags about 1/3 of the mammals would die. The endangered spotted owl feeds on these rodents and nests in old trees. For print friendly version press here.

What is the conflict over the forest? To answer that question consider these parts of a thorough response: 1. How many groups of people use this forest?
2. How did this conflict over the uses of the forest occur?
3. What did you feel were the salient (key or items of over-riding importance) facts in the forest problem?
4. What was your opinion in reading page 1, or the first half?
5. What was your opinion in reading page 2, or the last half?
6. What is your recommendation to the superintendent of the National Forest?
