Cheatgrass (Bromus tectorum L.) management and native plant community recovery on sites selectively treated with Imazapic in Rocky Mountain National Park
MetadataShow full item record
Cheatgrass, a winter annual grass introduced to North America from Eurasia, has invaded much of the Western United States over the last century. Recently, cheatgrass has become a threat to the montane and subalpine plant communities and ecosystems of Rocky Mountain National Park (RMNP). Cheatgrass aggressively invades disturbed sites and competes with native plant species by rapidly establishing a root system capable of depleting soil moisture and available nitrogen, making cheatgrass control a priority when restoring disturbed areas within RMNP. The purposes of this study were to determine the ...
