Natural recruitment of native forbs in the grassy ecosystems of south-eastern Australia
As for many lowland grassy ecosystem forbs in South-eastern Australia, the recruitment dynamics of the grassland forbs Podolepis sp. 1 sensu Jeanes 1999 (Basalt Podolepis) and Bulbine semibarbata perennial form (Leek Lily)are unknown. Podolepis sp. 1 and B. semibarbata were used as models of …

Prairie Restoration and Species Diversity: A Comparison of Propagation Success Between Seeded and Planted Forbs
… and conserving soil and water. The deep rooted forbs prevent water runoff and soil erosion. Economically the prairies have provided medicines, commercial forbs, and aesthetically pleasing landscapes for humans. Society is dependent on the rich soils these prairies have provided for agriculture …

The role of small mammals in the population dynamics of two native grassland forbs: Lupinus sericeus and Lithospermum ruderale
… plant establishment of two perennial grassland forbs: <i>Lupinus sericeus</i> (Fabaceae) and <i>Lithospermum ruderale</i> (Boraginaceae), using experimental seed addition and rodent exclusion treatments. For both species, small mammal exclusion increased the total number of seedlings that …

Forage Adaptability Trials for Forage and Seed Production in Bolivia; Effect of 5 Herbicides on 7 Native Utah Forbs
… native species should be used. Native forbs are a critical component of any natural ecosystem, and thus should be included in wildland restoration projects. However, because the seed is currently collected by hand from the wild, it is very expensive, and this limits the ability of land …

Responses of Above- and Belowground Forb and Plant Species Diversity to Grazing Exclusion and Fire in the Northern Great Basin Sagebrush Steppe
… native deep-rooted perennial bunch grasses and forbs, an increase in annual invasive grasses, and greater sagebrush dominance. Although not as widely used as perennial bunchgrasses, forbs of the Intermountain west have also been tested for use in rehabilitation purposes in the Intermountain …

CAN SHEEP CONTROL LEAFY SPURGE WITHOUT COMPROMISING EFFORTS TO RESTORE NATIVE PLANTS?
… stems grazed (pre- to post-grazing) of perennial forbs in 55 plots (including five controls) in an E. esula -invaded area with remnant native plants. Grazed plots had significantly fewer graminoid seedlings than un-grazed ones (28 vs 61/plot, respectively), but forb seedling density did not vary …

Food Habits of Deer In The Southern Black Hills As Determined By The Point Technique
… using chi-square analysis. Browse, grasses and forbs were estimated with no significant differences (P>0.05) using chi-square analysis: forbs 0 24.3 to 14.8, grasses – 26.5 to 25.7 and browse 51.3 to 58.4 percent. Twenty stomach samples were separated by hand after point analysis. Estimates of …

Examining the effects of seed mix diversity and composition, biochar application, seeding rate, species identity, and topography on Palouse Prairie restoration
… mix diversity and composition, the proportion of forbs to grasses, and seeding rate, and the most effective levels of each are not clear. Further, soil amendments, such as biochar, may benefit properties of tilled soils, but have not explored in Palouse Prairie systems. To address these knowledge …

The Effects of Mammalian Herbivores on Successional Grasslands in Central Illinois
… groups of animals reduced abundance of palatable forbs and increased that of unpalatable forbs. Grasses palatable to voles increased in exclosures during mid- and late succession. Rodent exclusion also significantly increased abundance of the legume Medicago sativa, which had highly palatable …

Biology of the Porcupine (Erethizon Dorsatum) in northwestern South Dakota

The effects of herbivory, competition, and disturbance on island meadows
… Canada’s most endangered ecosystem, native forbs have declined relative to non-native grasses and I tested the facilitatory role of herbivory in that degradation. My investigations, novel to the field, were conducted on islands spanning the Canada-US border. Islands served as natural …

A study assessing forage quality and desert bighorn sheep (Ovis canadensis nelsoni) diet in central Nevada using microhistology and molecular analysis
… quality of collected forages (grass, shrubs and forbs) collected at five study sites in the range. Forage quality was compared between sites and seasons. Forage types collected were also compared between sites and seasons and correlated to forage quality data. Microhistological analysis and PCR …

Effects of Cheatgrass Control on Wyoming Big Sagebrush in Southeastern Utah

The effects of mammalian herbivores on successional grasslands in central Illinois
