As a major pulp and paper production area, the Lake States is a potential market for pulpwood chips. As a producer of solid wood products, it has a considerable potential for the production of pulpwood chips from coarse sawmill residues (slabs, edgings, and trim) and other sources. Only a small amount of the available residues, however, is now being utilized. In response to numerous inquiries about pulp chips and sawmill residues, a study was begun on their production and marketing as well as any problem aspects that might require additional research. This note is a preliminary report.

The northern hardwoods type occupies about 16 percent -- 8.2 million acres -- of the commercial forest land in the Lake States. The timber has high unit values and represents about 42 percent of the total value of all the commercial forest in the region. Increasing values and markets for northern hardwoods in recent years have stressed the need for better quality in the finished product. Industry, therefore, is vitally iinterested in clear material, particularly for veneers and furniture stock and even for the relatively new use of the denser hardwoods for pulp. This interest, in turn, has...

Green or living fuels, particularly pine crowns, are commonly consumed by forest fires burning hot, windy weather. In some cases the pine crown fire has been known to burn ahead of surface-burning fire for some distance before dropping to the ground.

Second-growth northern hardwood stands occupy an important segment of the commercial forest land of Upper Michigan and northern Wisconsin. The size- and age-class distributions and species composition of these stands vary considerably, but under all conditions most of the trees are highly defective or poorly formed or of an undesirable species. Forest managers recognize the need for early thinning and improvement cuttings but have hitherto been reluctant to do noncommercial cutting. Now, however, not only are there active noncommercial operations on the National Forests of the region, but...

Accurate maps showing the distribution of important tree species are valuable to foresters, botanists, wildlife specialists, land managers, and others. Although the general natural ranges for our principal tree species have been well known for some time, new information continues to develop. Commercial ranges, hoever, have not previously been mapped precisely, and artificial extensions of ranges generally have not been mapped at all. Fore these reasons, range maps of the principal forest tree species have been prepared for the Lake States (Michigan, Minnesota, and Wisconsin), and that for...

Proposed construction in Missouri of pulpmills using oak cordwood should result in a greater demand for pole-size oak trees, thus making needed thinnings feasible in young oak stands. According to the 1958 forest survey, poletimber stands (which are mainly oak) occupy 39 percent of the commercial forest area of the eastern Ozakrs, more than any other size class. More intensive management of the large areas of oak-hickory poletimber stands will be possible as markets improve. Recent experimental thinnings in young, even-aged oak stands cut to several stocking levels provide data on possible...

In recent years there has been a great deal of concern about the closure of numberous hardwood face veneer and plywood mills in Michigan and Wisconsin. As part of an overall study of that industry in the northern Lake States region, the basic reasons leading to the closure of these mills were investigated. In the past 15 years, there have been eight known mill closures within the study area with an estimated total employment loss of 1,600 people. Presumably, each of these closures affected the economic equilibrium of the geographic areas in which they were located.

The two National Forests of Minnesota accommodate slightly over one-tenth of the private pleasure boaters in the State. There are more private boaters in the Superior National Forest than in the Chippewa. Boaters withing each forest come predominantly from the local area. Of the boaters from outside the local area, one-half come from the Twin Cities Metropolitan Area.

Families camping in auto campgrounds on the Huron-Manistee National Forests were studied in 1962. Among other questions, the campers were asked how much time they had spend in various activites on the day prior to the interview. This is a report on the replies to this question.
