GPS 12U E292753 N5563523.
Located on a range research station at Onefour, Alberta.
Total facility area in semi-native short grass prairie: 17,000
ha (42,000 ac).
The GLIDE study was confined in a grazing enclosure (barbed
wire fence) 100 m X 100 m.
Dominant grasses are Stipa comata (needle-and-thread
grass), Bouteloua gracilis (blue grama), Koeleria micrantha
(June grass), Agropyron spp., and some Poa and Carex. Some
shrubs such as Artemisia spp. (sagebrush), Elaeagnus commutata
(wolf willow, or silverberry) and Rosa acicularis (prickly
Dry mixedgrass grassland subregion. Mainly
low relief, flat grassland broken by low-flow stream valleys
or glacial deposits such as hummocky moraine, glaciofluvial
outwash and eroded lake deposits overlaying Cretaceous fine
sandstone and shale. Warm and dry climate (typically 250 mm
total annual precipitation) has resulted in sparse vegetation
cover short and medium-height grasses, and dark brown chernozems.
