B759: Balsam Fir (Abies Balsamea (L.) Mill.) Phenology In Maine, T. M. Mingo, J. B. Dimond
Bulletins
Spring phenology of balsam fir in Maine was investigated during 1978. Multiple regression models based on climatic and geographic factors were developed for predicting fir phenology and accounted for a maximum of 52.6% of the observed phenological variation. Generalized maps depicting observed and expected phenology patterns are also presented.

The purpose of this study is to establish the degree of reliability that can be placed in biomass as a means of assessing thinning potential and site productivity of immature forest stands in Maine. The above ground biomass on 205 plots representing a variety of age classes in immature hardwood and softwood stands on meso, wet, and dry sites was cut and weighed including the standing dead trees on softwood sites. In addition, 45 point sample biomass plots were located and measured in mature all aged stands. Graphical analysis was used to relate stand characteristics to age by site and …

Forests, and the manufacturing plants which make wood products are widely dispersed over eastern Texas . Their dispersion tends to obscure their economic impact. Two federal agencies, the Forest Service of the Department of Agriculture and the Bureau of Census of the Department of Commerce provide most of the available data on forest resources and the forest industry; isolation of some data is difficult, however, because some census categories combine data for non-wood manufacturing with that for wood products . This paper is an attempt to bring together the most pertinent data on the forest industries of Texas.
