- Library Collection RecordAs a whole, grasshopper densities were greater on ungrazed sites compared to grazed sites. Melanoplus sanguinipes and all species of Melanoplinae were greater on ungrazed sites, while Oedipodinae…Publication Date 1969

- Library Collection RecordBy the end of the second growing season in a Rhode Island salt marsh, biomass-removal plots had greater species richness than controls at high elevations (4.6 vs 2.4), while at low elevations,…Publication Date 1969

- Library Collection RecordIn this 3-year study of the vegetation in 4 livestock exclosures in North Dakota, Brand and Goetz found that the exclosures had greater graminoid leaf heights and greater mulch accumulation than the…Publication Date 1969

- Library Collection RecordThe effects of long-term summer sheep grazing in southwestern Utah were measured in this study by comparing a sheep-grazed pasture to an ungrazed pasture (occasionally grazed by horses/cattle). The…Publication Date 1969

- Library Collection RecordThe objective of this 8-year study was to evaluate the ecosystem-level impacts of no-grazing vs. sustained moderate and heavy cattle grazing, in terms of plant species basal cover, density, and…Publication Date 1969
