Many studies have indicated relationships between individual species, but none have related combinations of overstory variables to understory herbaceous vegetation in a Ponderosa pine/Gambel oak ecosystem. Our objective was to determine not only the

The Sheep Creek watershed of northcentral Colorado provided an ideal site to collect baseline trend data and to estimate foliar cover responses of montane riparian vegetation. Percent relative cover data were compared with Sorensen's similarity index

This paper describes an improved method for performing statistical comparisons among experimental groups. This technique, termed multi—response permutation procedures (MRPP), is similar in purpose to the t test and one—way analysis of variance F

Root production was slightly increased by nitrogen fertilization on four range sites. A major portion of the total root material was found in the upper 15.2-cm layer of the soil profiles on the Vebar, Rhoades, and Manning sites. A greater proportion

The objective of the study was to examine the interrelationships of soils, vegetation and position on the landscape in open geomorphic systems. The major landscape positions were the summit, backslope, footslope and toeslope. Beginning with the backs

The effects of clipping to a 2.54 cm (1 inch) height at 5 stages of development of western North Dakota mixed prairie were investigated. Soil moisture content at the beginning of the growing season had a greater effect on yields than did the clipping

A Iyear study of the vegetation in 4 livestock exclosures was begun in 1976 in the mixed grass prairie of southwestern North Dakota. Three of the exclosures were established in 1937 and the fourth in 1938. The excloaures had greater graminoid leaf he
