Mattheis Research Ranch

Located within the dry mixed grass natural subregion of Alberta, the Mattheis Research Ranch is part of a large contiguous tract of rangeland with diverse topography, vegetation and wildlife. The ranch is adjacent to the Red Deer River in the north and encompasses a creek, wetlands, vegetated sand hills, and shrublands.

The Mattheis Ranch was donated to the University of Alberta in 2010 by Edwin and Ruth Mattheis.

Site description
The Mattheis Ranch covers approximately 5,000 hectares, about 4,000 ha of which is native grassland, including loamy mixedgrass and sandgrass-dominated prairie, river coulee breaks, and riparian areas. Dominant grass species include needle-and-thread (Hesperostipa comata), Junegrass (Koeleria macrantha), blue grama (Bouteloua gracilis), and sand grass (Calamovilfa longifolia). The plant community also includes several forbs, such as pasture sage (Artemisia frigida) and scarlet mallow (Sphaeralcea coccinea) and shrubs, including prickly rose (Rosa acicularis), western snowberry (Symphoricarpos occidentalis), and thorny buffaloberry (Shepherdia argentea).

Irrigation-fed wetlands cover approximately 400 ha of the ranch. The water that circulates through these wetlands, most of which were created by Ducks Unlimited Canada in 1952, is delivered to 250 ha of cultivated land that is used to grow winter cattle feed, spring grazing pasture and annual crops. Irrigation water also augments several of the property’s natural wetlands.

Other anthropogenic features on the ranch include high voltage transmission lines, two provincial highways and an extensive network of oil and gas infrastructure.

Ranch management
The Mattheis Ranch is managed as a custom grazing operation. Since being acquired by the University of Alberta in 2011, the ranch has been rotationally stocked with approximately 800 beef cattle for an average of 6 months each year, beginning in early May.
