New research reveals Artemisia tridentata seeds can form a persistent seed bank, ensuring its survival in an invasive, fire-prone system Big sagebrush (Artemisia tridentata) is a key foundational species in an ecosystem that is threatened by invasion of cheatgrass and the subsequent increase in fire frequency. Critical to the conservation, reestablishment, and restoration of the sagebrush steppe ecosystem (which comprises 63 million hectares of the Great Basin of North America) is...

A new field study confirms that an invasive weed called medusahead has growth advantages over most other grass species, suggesting it will continue to spread across much of the West, disrupt native ecosystems and make millions of acres of grazing land almost worthless. The research, by scientists from Oregon State University and the Agricultural Research Service, was one of the most comprehensive studies ever done that compared the "relative growth rate" of this invasive annual grass to that...

Study raises concerns for agriculture In August of 2008 Jacob Schaefer, PhD, on vacation in San Diego, picked up a copy of the Los Angeles Times. As it happened, the newspaper was running a series on the wildfires in the western United States. The wildfires, he read, are more frequent "” they now occur every few years instead of every few decades "” and they are burning larger areas. The more intense fire cycle is fueled by cheatgrass (Bromus tectorum), an invasive plant that is...

Global warming is likely to result in more preferred conditions for many of the most unwanted weeds to invade the West, researchers reported on Friday. Additionally, climate change may also allow farmers to restore native plants in some regions, said Bethany Bradley, Research Associate at Princeton and lead author of the study appearing in Global Change Biology. While the changing climate may rid the west of many invasive plants that already reside in the region, others are expected to take...

By Patrick O'Driscoll Western states work to defend landscapes as cheatgrass overruns areas DENVER -- Cheatgrass, a wispy Eurasian weed accidentally brought to the USA in the late 19th century, has become a 21st century headache across the West, fueling some of this summer's most destructive wildfires. The largest blaze in Utah history, the 567-square-mile Milford Flat fire last month raced across rangeland infested with the highly combustible, straw-colored plant. Bone-dry expanses of...

SPOKANE, Wash. (AP) - A fungus scientists have dubbed "Black Fingers of Death" may turn out to be the first long-range weapon in efforts to halt the advance of cheatgrass, a destructive invasive weed, scientists say. Gonzaga University biology professors Julie Beckstead and David L. Boose were recently awarded $247,000 in federal grants for a three-year study on pyrenophora semeniperda, a tiny, naturally occurring soil fungus that attacks the seeds of cheatgrass. Working with colleagues at...
