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.

The role of plant chemistry in successful biocontrol

Projects Posted on: August 21, 2015
Invasive plants and their negative effects on biodiversity and landscapes are one of the greatest threats to ecosystems. The importance of plant chemistry in successful biocontrol is becoming evident, and the emerging science on plant-insect chemical ecology should provide valuable information regarding what types of insects are most likely to impact weed populations - saving time and money and maximizing the success of this powerful management tool.

Biology of the invasive banded elm bark beetle (Coleoptera: Scolytidae) in the western United States

Publications Posted on: September 14, 2011
The banded elm bark beetle, Scolytus schevyrewi Semenov (Coleoptera: Scolytidae), native to Asia, was detected in the United States in 2003, and as of 2011 it is known to occur in 28 states and four Canadian provinces. S. schevyrewi infests the same elm (Ulmus spp.) hosts as the longestablished invasive, the European elm bark beetle, Scolytus multistriatus (Marsham).

Phytotoxic grass residues reduce germination and initial root growth of ponderosa pine

Publications Posted on: July 24, 2006
Extracts of green foliage of Arizona fescue and mountain muhly significantly reduced germination of ponderosa pine seeds, and retarded speed of elongation and mean radicle length. Three possible routes of release of the inhibitor were investigated: (1) leaching from live foliage, (2) root exudation, and (3) overwinter leaching from dead residues. The principal route remains uncertain.
