Development of remote sensing indicators for mapping episodic die-off of an invasive annual grass (Bromus tectorum) from the Landsat archive

Publications Posted on: September 25, 2017
The exotic annual grass Bromus tectorum (cheatgrass) dominates vast acreages of rangeland in the western USA, leading to increased fire frequency and ecosystem degradation that is often irreversible.

Linking wilderness research and management-volume 4. Understanding and managing invasive plants in wilderness and other natural areas: an annotated reading list

Publications Posted on: May 12, 2016
Nonnative invasive plants are altering ecosystems around the world with alarming speed. They outcompete native plants and ultimately change the composition and function of the ecosystems they invade. This poses a particular problem in wilderness and other natural areas that are set aside to maintain natural conditions.

Invasive Plants — Issues, Challenges, and Discoveries Webinar Series

Events Posted on: March 15, 2016
The USDA Forest Service Rocky Mountain Research Station hosted a webinar series, Invasive Plants — Issues, Challenges, and Discoveries Webinar Series, to provide attendees with cutting-edge information about invasive plants and their management. This webinar series was sponsored by the Station’s Grassland, Shrubland and Desert Ecosystems Science Program.

Celebrating 30 years of the Fire Effects Information System (FEIS)

Science Spotlights Posted on: November 10, 2015
Thirty years ago, Rocky Mountain Research Station scientist William (Bill) Fischer proposed a highly innovative computer system to provide managers with information about the effects of prescribed fire. Technology has changed radically since Fischer originally envisioned a computer program to provide fire effects information electronically. The FEIS user interface now enables readers to search using many criteria, including maps, and it connects information from all three FEIS products - Species Reviews, Fire Studies, and Fire Regimes.

Unwanted side effects of roads are invasive species

Science Spotlights Posted on: October 22, 2015
Resource managers are using burning and thinning treatments more and more in western forests to manage the infestation of insects and disease as well as to reduce wildfire hazards. Unfortunately, these treatments can trigger the invasion and spread of invasive plants, which can thwart restoration efforts. A recently published, long-term Forest Service study conducted at the Tenderfoot Creek Experimental Forest (TCEF) in Montana helps shed some light on the spread of invasive plants.

Plant invasions: How do mild-mannered plants transform into superinvaders?

Projects Posted on: May 19, 2015
For over 10 years, Rocky Mountain Research Station scientists and their partners have engaged in research to 1) determine the causes underlying plant invasions, 2) identify invader impacts in native systems, and 3) improve the efficacy of invasive plant mitigation efforts.

The ‘dirt napping’ stem miner: Potential for classical biocontrol of yellow and hybrid toadflax

Projects Posted on: May 11, 2015
Optimizing classical biological control through the deployment of environmentally resilient agents may provide a sustainable, cost-effective and selective management option for large scale infestations of fire adapted weeds. Ongoing research is exploring the efficacy of a candidate agent, the stem mining weevil Mecinus heydenii, for biocontrol for invasive toadflax.
