Forest Soils-Site Index Studies in Maine¹

ABSTRACT

The field, laboratory and analysis technique employed by Coile and his students in forest soils-site index studies in the South have been tried on a modest scale in Maine. A White Pine study based on 16 plots located in 16 different White Pine stands in the vicinity of Orono, Maine, yielded a regression equation which correlated site index with the depth of the A horizon and the percentage of stones in the B horizon. As both of these factors increase, the site index decreases. This was field checked in a series of white pine stands within a 50 mile radius of Orono and in the southern part of the state along the Maine Turnpike. Data were also collected on 16 plots in spruce-fir stands on the Penobscot Experimental Forest and this yielded a regression equation correlating the site index of spruce with the depth of the A horizon and the inhibitional water value of the A horizon. As both of these increase, the site index for spruce decreases. It is apparent that Coile's methods apply in Maine. Further study based on many more plots and covering a wider range of conditions are essential to obtain equations that can be used in practical forest management.
