Pre‐fire grazing and herbicide treatments can affect post‐fire vegetation in a Great Basin rangeland

Landscape-level interactions of prefire vegetation, burn severity, and postfire vegetation over a 16-year period in interior Alaska

Landsat imagery was used to study the relationship between a remotely sensed burn severity index and prefire vegetation and the postfire vegetation response related to burn severity within a 1986 burn in interior Alaska. Vegetation was classified prior to the fire and 16 years after the fire, and a chronosequence of remotely sensed vegetation index values was analyzed as a surrogate of vegetati...

Postfire Seeding and Plant Community Recovery in the Great Basin

As wildland fire frequency increases around the globe, a better understanding of the patterns of plant community recovery in burned landscapes is needed to improve rehabilitation efforts. We measured establishment of seeded species, colonization of Bromus tectorum and other nonnative annual plants, and recovery of nonseeded native species in topographically distinct areas within five fires that...

Postfire Plant Establishment: The Effects of Environment, Prefire Vegetation, Fire Severity, and Landscape Position

Great Basin Vegetation in the Late Pleistocene

Paleoecological sources indicate that the location and extent of Sierra Nevada rangelands have varied significantly during the last 20,000 years. Modern vegetative associations are recent, with montane wet meadows appearing during the last 3,000 years. A late Pleistocene sagebrush grassland existed where montane and subalpine forests occur today. In the central Sierra a pattern of deglaciation ...

Vegetation response to seven grazing treatments in the Northern Great Plains

Grazing systems may alter botanical composition and productivity of grasslands through differential use in time, space, or intensity. Seven simulated grazing treatments were applied six years in eastern Montana, USA to determine effects on plant community composition and standing crop. Treatments were moderate stocking (28.8 AUD ha 1 year ) of cattle using 3-pasture summer rotation, season-long...
