Analysis of a North Dakota Gallery Forest: Nutrient, Trace Element and Productivity Relations

Abstract
The vegetation of a gallery forest in eastern North Dakota [USA] was studied with emphasis on the documentation of nutrient flows and vascular plant production on 2 opposing slopes. Tree basal area, density and cover-abundance differed between slopes although the dominant species on both was bur oak Quercus macrocarpa Michx. Species diversity was greatest in mid-slope study plots and lowest in upper-slope plots. Mean dissimilarity of vegetation between slopes was 36%; dissimilarity decreased with height above the herb stratum. Gross precipitation and soil composition were discussed.
