Provides current information on lumber and plywood production and prices; employment in the forest industries; international trade in logs, lumber, and plywood; volume and average prices of stumpage sold by public agencies; and other related items.

Observations of thinned ponderosa pine infested with dwarf mistletoe over a 17-year period suggests that on average or better Sites most infested stands can be managed to produce usable wood products in reasonable time, if trends found in juvenile stands continue.

The spotted owl (Strix occidentalis caurina) has been listed as a sensitive species by the Pacific Southwest Region USDA Forest Service. Past and present-studies-and surveys have led to the development of a region-wide network of owl territories to comply with the maintenance of viable populations as required by the National Forest Management Act. A brief explanation of the network is included.

Management practices and options to provide habitat for wildlife in the Great Basin of southeastern Oregon deal with both vegetation treatment and protection, livestock management, maintenance or distribution of water developments, protection of wildlife areas through road closures or fencing, and direct manipulation of wildlife through hunting, trapping, or other means. This chapter deals primarily with livestock management in relationship to wildlife and wildlife habitat. Included are discussions of ecological status (range condition), livestock management, multiple-use options for each...

Decreases in sage grouse followed the decrease in sagebrush. Other factors, such as unfavorable weather conditions at hatching time and increased predation, hunting, and disease have each been important at various times in localized areas but are probably not the most important factors in the overall downward trend.

The effects of two levels of residue removal (removal of all woody material larger than 15 x 180 cm and 10 x 120 cm) on the distribution of nitrogen and sulfur on the forest site and the added effects of post-harvest prescribed fire on those distributions were studied at two sites in the Cascade Range in Oregon. Nutrients lost from increased removal of residue were small compared with nutrients removed in merchantable timber. Differences in the amount of nutrient capital removed during harvest between the two levels of residue removal amounted to 1 percent of the total site nitrogen and 4...

A multiresource inventory of the Beluga block, Susitna River basin inventory unit, was conducted in 1980. Statistics on forest area, timber volumes, and growth and mortality from this inventory are presented. Timberland area is estimated at 131,740 acres and net growing stock volume, mostly hardwood, is 99.4 million cubic feet. Net annual growth of growing stock is estimated at 1.4 million cubic feet and annual mortality at 773,000 cubic feet.

This guide identifies 49 common plants of coastal Alaska muskegs. Plants are divided into six major groups: clubmosses, ferns, sedges, herbs, shrubs, and trees. Illustrations and short descriptions of each plant are provided, along with a simplified key to aid in identification. The guide has been prepared with the amateur botanist in mind, and technical terminology has been largely eliminated. A glossary and illustrations are provided to explain the botanical terms used.

Early height growth of ponderosa pine (Pinus ponderosa Dougl. ex Laws.) seedlings planted in clearcuts in central Oregon was negatively correlated with increasing soil bulk density. Change in bulk density accounted for less than half the total variation in height growth. Although many other factors affect the development of seedlings, compaction has reduced the rate of height growth.
