- Title: Drought and grazing: IV. Blue grama and western wheatgrass
- Journal: Journal of Range Management
- Authors: E. J. Eneboe, B. F. Sowell, R. K. Heitschmidt, M. G. Karl, and M. R. Haferkamp
- Date: 2002
- Summary: This study, Eneboe et al. tested the theory that grazing, during or after drought, could reduce the recovery of plant communities from drought by measuring the tiller dynamics and plant growth of two dominant grassland species (western wheatgrass (Pascopyrum smithii) and blue grama (Bouteloua gracilis)) in eastern Montana following an imposed severe drought. Tiller recruitment, and tiller density of blue grama and western wheatgrass plants were not negatively affected, and were sometimes enhanced by drought and/or grazing during, and one year followin ...

- Title: Water relations of Agropyron smithii and Bouteloua gracilis and community evapotranspiration following long-term grazing by prairie dogs
- Journal: American Midland Naturalist
- Authors: T. A. Day, and J. K. Detling
- Date: 1994
- Summary: The effects of intensive grazing by black-tailed prairie dogs (Cynomys ludovicianus) on water relations and community evapotranspiration on a northern-mixed prairie near Wind Cave National Park in South Dakota (37˚ 30’ N; 103˚ 17’ W), was examined on a heavily grazed, colonized site and on a nearby lightly grazed, uncolonized site. Aboveground production, leaf water-relations, canopy air temperature, wind speed and relative humidity were measured at each site. ...

- Title: Woody plant invasion of grasslands: Establishment of honey mesquite (Prosopis glandulosa var. glandulosa) on sites differing in herbaceous biomass and grazing history
- Journal: Oecologia
- Authors: J. R. Brown, and S. Archer
- Date: 1989
- Summary: Honey mesquite (Prosopis glandulosa) seedling emergence and survival was determined on pastures, with and without a long history of grazing, that were exposed to moderate and heavy defoliation intensities. Defoliation enhanced survival of mesquite seedlings because of the reduction in overstory cover that allowed more light to reach emerging seedlings. Root biomass was greater on sites without a long history of grazing, however, site history, root biomass and proximity of seeds to grasses did not affect seedling emergence or survival. These results indicate that levels ...
