The second forest inventory of North Dakota shows growing-stock volume reaching 207 million cubic feet in 1980. Hardwoods make up more than 99 percent of this total.

In 1980 Michigan's forests covered 18.4 million acres, a decline of 5.2 percent from the 19.4 million acres reported in 1966. Commercial forest land dropped to 17.5 million acres.

Picea glauca and P. amithiana were successfully crossed. Crossability ranged from 2 to 30 percent depending on the female P. glauca parent tree. Early characteristics and growth in Wisconsin and in New Brunswick are described. P. smithiana relatedness in the genus is discussed

Describes two methods for improving site index estimates in diffuse porous even-aged northern hardwood stands

Lake States pulpwood production fell to 5.60 million cords in 1981. Pulpwood production is shown by county and species group in Michigan, Minnesota, and Wisconsin.

In 1980 eastern South Dakota's forest resources covered 266,300 acres of land, a slight decline from the 296,600 acres reported in 1965. The area of commercial forest land also dropped from 165,400 acres to 113,600 acres. The elm-ash-locust forest type covers 40 percent of the commercial forest area.

Measurements of more than 20,000 Missouri trees were summarized by species and diameter class into tables of mean annual diameter growth, annual probability of survival, net cubic foot volume, and net board foot volume. In the absence of better forecasting techniques, this information can be utilized to project short-term changes for Missouri trees, inventory plots, stands, or forests

A statistical report on the third forest survey of New York conducted in 1978 and 1979. Statistical findings are based on data from remeasured and new 10-point variable-radius plots. The current status of forest-land area, timber volume, and annual growth and removals is presented. Timber products output by timber industries, based on a 1979 updated canvass of manufacturers is presented.

System 6 is a technology for converting low-grade hardwood to high-valued end products such as furniture and kitchen cabinets. Among its concepts are: (1) a new, nonlumber product called standard-size blanks; (2) highly automated methods of converting the logs to blanks; (3) total processing of every board that contains a minimum-size cutting; and (4) minimized machine operator decisions and limited choices. While details of procedure and machinery may vary, the seven steps given are considered mandatory for profitable low-grade hardwood conversion.
