Equations have been developed for estimating the volume per acre of sawlogs, sawbolts, and pulpwood of fuelwood that can be harvested by thinning hardwood stands of poletimber or small sawtimber size. These equations were derived from actual roundwood yields obtained by thinning 17 stands of Appalachian hardwoods in Virginia and West Virginia, and measuring the product volume of each cut tree 5.0 inches in d.b.h. and larger. If the amount of basal area to be removed per 2-inch d.b.h. class is known, the equations facilitate estimates of alternative yields from thinnings and help identify opportunities for multiproduct harvesting.

As logging employment continues to decline and forestry service employment grows, as they have over the past several decades, it is increasingly important to understand the relative quality of jobs in these two sectors. This study compares wages and job durability of loggers and forestry service workers in Oregon using unemployment insurance data. Using multiple wage measures (hourly, annual, and outside wages) and multiple job durability measures (employer changes, outside employment, seasonality, quarterly hours worked, and retention), this study finds that loggers typically earn more and have more durable jobs than forestry service workers.

Four years after its inception an outreach campaign promoting forest stewardship in south-central Connecticut was carefully evaluated. Results emphasize that efforts may be directed to promoting a simpler and more autonomous form of resource inventory and forest stewardship planning than many forestry specialists might originally envision. Evaluation methods used to measure the success of outreach efforts should recognize a continuum of possible outcomes, not simply the ideal.

Data for this study were collected using a questionnaire mailed to randomly selected members of two forest owner organizations. Among the key findings is that 38% of forest estates owed federal estate tax, a rate many times higher than US estates in general. In 28% of the cases whereestate tax was due, timber or land was sold because other assets were not adequate. In 29% of the cases where land was sold, it was converted to a more developed use. Questionnaires also were mailed to randomly selected individuals from a national database of rural landowners for comparisonwith forest owners. For most of the characteristics surveyed, there was no statistical difference between responses from the two groups.

Stands of ponderosa pine in the Black Hills National Forest have been subject to management by professional foresters longer than any other western timber type. This management began with the first regulated sale of timber from a forest reserve, referred to as Case No. 1. While more than 5 bbf of timber were removed from this forest during the last 100 years, timber volume has grown from 1.5 bbf in 1899 to more than 5 bbf today. Case No. 1 is an excellent example of how effective forest management can sustain multiple forest resources.

A method to estimate the direct and indirect changes in local area employment, income distribution, and tax revenues is given and its usefulness for evaluating various Forest Service policies illustrated. Policies studied are those which decrease allowable timber cut by 10 percent, decrease animal units on the forest by 20 percent, and increase forest-related tourism by 10 percent in two trade areas of Arizona. The policies have a combined effect which only marginally changes employment in each area. Timber and range policies are regressive with respect to income distribution, and the tourism policy is progressive. The individual and combined effects of the assumed policies on tax revenues are small. Policy effects vary among areas of differing economic structures.

In 1967, black walnut (Juglans nigra L.) seedlings from 15 to 25 provenances were planted at eight locations in the Midwest. In 1973, a similar plantation was established near Yoncalla, Oregon. Results show that, within the species' natural range, provenances can be moved as much as 200 miles northward without the likelihood of cold damage. In general, growth of trees from southern sources exceeds that of trees from northern sources.

Florida posseses climatic, land, and water resources favorable for abundant biomass production. Therefore, a statewide program has been initiated to determine adapted species for the available array of production sites. Plant resources under investigation include woody, aquatic, grasses, hydrocarbon, and root crop species. The goal is to produce a continuous stream of biomass for the various biofuel conversion options. Preliminary yields from energy cropping experiments, range from about 10 to nearly 90 metric tons per hectare per year, depending on the crop and the production system employed.
