Changes in limb-;elated stem defect were studied from 1977 to 1982 on 595 mixed-oak trees fbllowing a schedule of thinnings dating back to 1962. All of the thinnings were controlled by stocking goals rather than predetermined time intervals. Results show that heavy and moderate thinnings, as opposed to light thinnings,lhad an adverse effect on the number and size of live and dead limbs. The light thinnings resulted in fewer live and dead limb defects per square foot ofisurface area but much slower diameter growth.

Although imports of most hardwood products have varied since 1970 with no absolute trend, imports of hardwood plywood have decreased while imports of wood furniturd have increased dramatically.

Evaluates regional timber output based on the results of a survey of the timber industries of southern New England. Contains statistics on industrial timber production and receipts in Connecticut, Massachusetts and Rhode Island, by state and species, log shipments between states, sawmills and lumber production, and the production and disposition of manufacturing residues. Comparisons are made with historical and recent data, and trends in industrial wood output are noted. Includes graphics and statistical tables.

This annual report contains 1986 information compiled from a canvass of all pulpmills that use pulpwood produced in the 14 Northeastern states. In 1986 total production reached 8,952,400 cords. This was up by 2 percent since 1985. Roundwood production was 6,602,400 cords whereas pulpwood from residues was 2,350,000 cords. Each of these increased from the previous year, by 2 percent and 1 percent, respectively. The receipts of pulpwood at mills in the region were 9,385,300 cords.
