Oregon's 1968 timber harvest of 9.74 billion board feet was the largest since 1952, when a record 9.80 billion board feet was produced. Public agencies' harvests increased 25.0 percent in western Oregon and 4.1 percent in eastern Oregon for a total increase of 19.1 percent, 864.9 million board feet above the public harvest in 1967. National Forests had the largest production increase of 460.8 million board feet (up 14.5. percent), followed by the Bureau of Land Management's increase of 378.0 million board feet (up 34.6 percent) and by the state's increase in production of 34 million board...

During the first 4 years following application, addition of 200 to 600 pounds of nitrogen per acre increased height increment 62 percent and d.b.h. increment 79 to 160 percent. Gross basal area increment was greater with heavier fertilizer applications, but severe snowbreakage wa also increased. Thus, net production tended to be greatest with the addition of 200 pounds of nitrogen. Indications are that heavier application rates will have a longer lasting beneficial effect.

Decomposition of thinning slash deposited on the soil surface should have no direct adverse effect on the soil nitrogen available to higher plants in the pumice soil region. Decomposition of roots of cut trees would immobilize nitrogen in the soil immediately adjacent to the root during the decomposition period, which appears to be short for the smaller roots. However, these dead roots no longer compete for soil nitrogen in unexploited soil zones. Thus, nitrogen available for individual trees may be increased by thinning. If chipped slash is mechanically incorporated into the soil, a...

Oregon's timber harvest was 8.4 billion board feet in 1967, 6.3 percent below the 1966 harvest. The total private harvest declined 7 percent in 1967 with a 153-million-board-foot (4.3-percent) decrease in western Oregon and a 138-million-board-foot (22.7-percent) drop in eastern Oregon. Forest industries had the greatest decline in production of all owners; their harvest of 3.2 billion board feet was down 405 million board feet (11.1 percent). By contrast, the other private lands increased their harvest in 1967 to 598 million board feet, up 114 million board feet (23.7 percent).

This report presents the first complete inventory of Humboldt County's timber resources. Past Forest Survey inventories have included Humboldt County, but they were not designed to obtain volume estimates for an individual county. Humboldt County is part of a survey unit which also includes Del Norte County. There are eight such inventory units in California; and each unit, composed of a group of counties, will be reinventoried and reported upon at 10-year intervals.

In 1967, the forested area of Humboldt County totaled 1,850,000 acres, or approximately 81 percent of the county's total land area. Of the total forest land area, 1,701,000 acres, or 92 percent, is commercial forest land; 47,000 acres is productive-reserved forest land in State parks; and 102,000 acres is unproductive forest land.

This publication summarizes the results of the third inventory of the timber resources of nine counties in central Oregon: Crook, Deschutes, Gilliam, Jefferson, Klamath, Lake, Sherman, Wasco, and Wheeler. This block of nine counties is one of 10 such blocks set up in the States of Oregon and Washington by the Forest Survey to facilitate orderly reinventories of the timber resources. Each block will be reinventoried at 10-year intervals and the results published in a single report for the block. The five blocks in Oregon are northwest Oregon, west-central Oregon, southwest Oregon, central...

Precommercial thinning lately has become a major feature in management of ponderosa pine (Pinus ponderosa Laws.) on the National Forests in Oregon and Washington. Nearly 47,000 acres were thinned in 1966, up from 9,196 in 1959; and the upward trend appears certain to continue. Current practice is to cut the trees with a powersaw about a foot above the ground and let them lie as they fall. The slash, i.e., the felled trees, becomes a fire hazard as soon as it dries. It also obstructs access, provides a breeding place for certain insect pests (notably engraver beetles, Ips sp.), temporarily...

Alaska's romantic past includes the magnetic lure of gold; the mad stampede to strike it rich; success and heartbreak; men and animals battling snow, ice, spring breakup, insects, and loneliness; dog teams at work and on desperate missions; river steamers battling the Yukon; bush pilots performing miraculous flights; and hordes of salmon taken by traps and seine hats. Places like Skagway, Dawson, Nome, Juneau, and Fairbanks were boom towns. Fortunes were made, gambled, and lost overnight.

Washington's 1967 timber harvest declined to 5.9 billion board feet, 2.3 percent below the 1966 harvest. The cut on public lands remained about the same as in 1966 with a 6.7-percent increase in public cut in eastern Washington, offsetting a 2.2-percent decrease in western Washington. The Indian lands had the greatest increase in harvest, up 35 million board feet, followed by National Forest lands with an increase of 27 million board feet. The 71-million-board-foot drop (13 percent) in cut on State lands was accompanied by a 297-million-board-foot increase (45 percent) in the uncut volume...
