Clipping and Watering Effects on Caespitose and Rhizomatous Grasses: Implications for Grazing ManagementDownload
Recent experimental evidence suggests that rotational grazing, despite strong perceptions to the contrary, does not promote plant community productivity relative to continuous grazing on rangelands. However, clipping studies from tame pastures of Alberta’s Aspen Parkland show clear plant...
Hybrid poplar plantations have the potential to produce large amounts of biomass for the forest industry, but the young trees are sensitive to competition. This research attempted to quantify the influence of factors regulating competition in hybrid poplar plantations under four years old. The...
Populations of feral horses have been increasing in the Alberta foothills and pose a concern to the conservation of native grasslands. Sustainable management of feral horses requires information on their habitat use. I utilized spatial data from radio-collared mares to assess seasonal habitat...
Legume-grass forage mixes for maximizing yield and competitiveness against weeds in early establishmentDownload
A field experiment from 2003 to 2005 at two sites examined the impacts of forage species and legume proportion on forage sward production. Grasses generally established rapidly and out-yielded swards high in legume content, although legumes did improve forage quality. Alfalfa was retained at...
Rangeland Habitat Use and Activity of Cattle with Divergent Molecular Breeding Values for Residual Feed IntakeDownload
Selection for the trait residual feed intake (RFI) is an emerging tool for cattle producers to manage feed costs within the beef industry. This study explored whether cattle habitat use and activity on extensive pasture-based systems in the dry mixedgrass of Alberta differed between cattle with...
Relationships of Range Health Scores with Grazing Management Practices and Producer Perspectives in Alberta, CanadaDownload
Livestock management systems are becoming an increasing focus of attention in scientific study. An area of study that has not been heavily investigated is the social dimension of grazing management. Why do some livestock producers choose one form of grazing management over another? Why is there...
