The effects of early spring burning on current year standing crop, litter, and total standing crop (current year standing crop plus litter) were examined in Festuca- and Stipa-Agropyron-dominated communities in central Saskatchewan over an 11-year pe

Fringed sagebrush (Artemisia frigida Willd.), the most common dicotyledonous species in the Northern Mixed Prairie, often increases dramatically following disturbance. It was hypothesized that the increase could be due to release of established plant
