The Forest Wealth of Oregon (Classic Reprint)


Book Description

Excerpt from The Forest Wealth of Oregon The State of Oregon has approximately three hundred billion feet, B. M., of standing timber according to the average of the estimates made by different timber men and experts who have made the matter a thorough study. This is a much greater amount than is possessed by any State in the Union, and is nearly one-sixth of the total amount of standing merchantable timber of the United States. The value of this immense body of timber is twofold: Firs t, as a source of lumber sup ply; second, as a factor in the maintenance of a'perpetual flow of water in the streams and rivers of the State, by retarding the melting of the snow and holding a con tinuous supply of moisture in the ground during the summer months. Other minor uses of forests are as a fuel supply, and as a source of ornamental trees and shrubs, and in the production of medicinal and edible products useful to mankind. Commercially, the value of the standing timber of Oregon when manufactured into lumber and sold at the rate of $12 per M. Would be 000, a sum in excess of the total amount of money in currency in the United States at the present day. The most densely timbered area in the State is West of the Cascade Range. This is due to more humid conditions, favorable to rapid and abundant development of plant life. Thus we find that eighty per cent of the total stand of timber is found on an area which is thirty per cent of the total area of the State. The average stand of timber on the forested area west of the Cascade Ran ge is feet, B. M., per acre. Localities where the stand is feet per acre are common, as in portions of Clatsop, Tillamook, Polk, and other coast counties.

Instability of Forest Land Ownership in Western Oregon and Washington, 1932-41 (Classic Reprint)


Book Description

Excerpt from Instability of Forest Land Ownership in Western Oregon and Washington, 1932-41 By 1950 unstable forest land ownership attracted national attention, It seemed to be most critical in the Lake States and the South, It was approaching a critical stage in the Pacific Northwest, Some private land was going back to the counties, some to the States, and some to the Feder= al government, Land was reported as reverting to public ownership in such -condition that it could neither yield the taxes levied against it nor, without organized management, recompense the public in any degree for the public debts accumulated on it, For the most part there was no adequate plan for handling this land, As'a result, local political organization was upset and the economic foundations of communities and regions were undermined, Tax=reverted land areas far exceeded in magnitude the public programs of acquisition for forest purposes, e.

Streamflow After Patch Logging in Small Drainages Within the Bull Run Municipal Watershed, Oregon (Classic Reprint)


Book Description

Excerpt from Streamflow After Patch Logging in Small Drainages Within the Bull Run Municipal Watershed, Oregon Changes in annual water yield, mini mum streamflow, and instantaneous peak flow (the maximum rate of streamflow caused by a rain or snow melt event) are all important in municipal watershed management. If timber cutting can increase water yield, then a municipal watershed might be made to yield more water, particularly during the summer period of low flow. Increased size of peak flows as a result of timber harvest might be associated with not only overland flow and attendant surface erosion but also erosion of stream channels. Both factors could adversely affect water quality. In 1955, the usda Forest Service and the City of Portland, Oregon, began a cooperative study to determine effects of timber harvest on water yield and timing of runoff and the quality of streamflow in three small watersheds within the Bull Run Municipal Watershed. This report deals only with changes in quantity and timing of streamflow. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
