Employment and earnings in Oklahoma's forest products industry, like those of most Southern States, grew significantly between 1970 and 1980. In fact, Oklahoma's share of the Nation's forest products employment and earnings increased during this period. In 1980, lumber and wood products accounted for the largest share of the industry's employment, but paper and allied products had a larger share of the earnings. In 1977, pulp and allied products had higher productivity than either lumber and wood products or wood furniture.

This comprehensive catalog of viral diseases of three large groups of arthropods updates the previous surveys of the world's literature published by Hughes in 1957, by Martignoni and Langston in 1960, and by Martignoni and Iwai in 1975. This computer-based catalog lists over 1,100 species of insects, mites, and ticks, each reported to have one or more of 22 viral diseases or disease groups, for a total of about 1,690 host-virus records. The catalog consists of two lists. In the first one, the hosts are listed in taxonomic sequence (order, family, genus, species). Families appear alphabetica...

A survey of timberland cut over from 1956 to 1971 in the Applegate, Evans, and Galice-Glendale areas of southwestern Oregon showed that both partial cuts and clearcuts were well stocked with a combination of regeneration that started before and after harvest cutting. Advance regeneration was a major stocking component in partial cuts. Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) was the predominant species of advance and subsequent regeneration in both partial cuts and clearcuts. Stocking differed significantly by forest type, soil series, soil origin, soil depth, and stream drainage...

Ratios are presented for estimating volume and characteristics of logging residue in California. The ratios relate cubic-foot volume of residue to thousand board feet of timber harvested and to acres harvested. Tables show gross and net volume of residue, with and without bark, by diameter and length classes, by number of pieces per acre, by softwoods and hardwoods, by percent soundness, and by degree of slope and distance to roads.

Conifer seeds were sown in clearcut Abies amabilis/Achlys triphylla and Abies amabilis/Vaccinium membranaceum/Xerophyllum tenax habitat types in the McKenzie River basin in Oregon to determine ratios of seeds to established seedlings. Protection from animal predation and shade from stumps were beneficial, but survival and growth did not differ significantly between habitat types or among humus treatments. Germination in the greenhouse was earlier and more prolonged on soils from the Achlys type.

Employment and earnings in Kentucky's forest products industry, like those of most Southern States, grew significantly between 1970 and 1980. In fact, Kentucky's share of the Nation's forest products employment and earnings increased during this period. In 1980, lumber and wood products accounted for the largest share of the industry's employment, but paper and allied products had more earnings. Furthermore, in 1977, pulp and allied products had higher productivity than either lumber and wood products, or wood furniture.

Until the 1970's, the Pacific Northwest dominated national markets for softwood lumber and plywood. During the 1970's, however, the region's share declined while production increased in the South. Meanwhile, the South's and the Pacific Northwest's shares of the Nation's employment in lumber and wood products declined. This resulted mainly from the increase in lumber imports from Canada and the construction of new, state-of-the-art plywood mills in the South. Trends in Canada and the South suggest that the Pacific Northwest could regain its dominant position as the supplier of solid...

Six studies were used to compare differences in recovery of volume and value among live, recent dead, and older dead lodgepole pine (Pinus contorts Dougl. ex Loud.) in the Western United States. The products studied included boards, random-length dimension, studs, and veneer. For the average size log (12 cubic feet) absolute values were highest for boards, followed by dimension, veneer, and studs for both live and dead timber. The percentage change in value from live to dead, however, showed the reverse order; studs lost the least value and boards the most.

Employment and earnings in South Carolina's forest products industry, like those of most Southern States, grew significantly between 1970 and 1980. The forest products industry accounted for a larger share of the State's economic base in 1980 than in 1970. Moreover, during this period, the State increased its share of the Nation's forest products industry employment and earnings. Pulp and allied products had the highest productivity, but lumber and wood products experienced the largest increase in productivity between 1972 and 1977.

This paper examines five "timber-dependent" counties in the Pacific Northwest to document: (1) net migration rates of older (and presumably retired) people into these counties, and (2) changes in the economic base of each county during the 1970's. We identify a "retirement" sector and argue that it has become a major economic sector in three of our study counties. This development has at least two implications for natural resource management in such counties. First, economic diversification may lessen the effects of projected declines in timber harvests. Second, local concern for the...
