Soil heating, nitrogen, cheatgrass, and seedbed microsites

, 1994
Heat-induced changes in the soil-solution and post-wildfire erosion can create chemically and texturally diverse seedbed microsites. We quantified organic carbon, extractable NH4+ after incubation (aerobic and anaerobic), and emergence of cheatgrass ...

Phenology forecasting models for detection and management of invasive annual grasses

Ecosphere
Non‐native annual grasses can dramatically alter fire frequency and reduce forage quality and biodiversity in the ecosystems they invade. Effective management techniques are needed to reduce these undesirable invasive species and maintain ecosystem ...

Indicators of ecological resilience and invasion resistance − accounting for precipitation seasonality and climate change in southwestern U.S. drylands

Ecological Indicators
Spatially explicit and climate sensitive information on the responses of ecosystems to global change processes is required for strategic planning and prioritization of conservation and restoration.

Soil climate underpins year effects driving divergent outcomes in semi‐arid cropland‐to‐grassland restoration

Ecosphere
Converting croplands to grasslands can restore ecosystem functions and services, but there is uncertainty about why some restoration treatments succeed and others do not.

Crested wheatgrass-cheatgrass seedling competition in a mixed-density design

, 1996
Plant competition experiments have historically used designs that are difficult to interpret due to confounding problems. Recently, designs based on a "response function" approach have been proposed and tested in various plant mixture settings.

Cheatgrass Invasion in Salt Desert Shrublands: Benefits of Postfire Reclamation

, 2007
In 1998, fires burned more than 11 330 ha of rangeland on Dugway Proving Ground in Utah’s west desert. Postfire revegetation was implemented in 2 affected salt desert shrub communities (greasewood; Sarcobatus vermiculatus Hook.

Cheatgrass Coloration—A Key to Flammability?

, 1967
The drying rate of cheatgrass was studied on four plots in western Montana and northern Idaho. The characteristic color changes in cheatgrass while it is curing (from green to purple to straw color) are proposed as an indicator of impending flammability ...
