  • One of the most invasive exotics in the western United States, the yellow starthistle, is successful both at "invasion" in non-native areas and "colonization" in native ones.

    Science

  • Spotted knapweed, also known as starthistle, was introduced in the U.S. from Europe in the late 1800s.

    Will Killing This Invasive Plant Harm Bees?

  • However, new research from an international team of researchers finds that a disturbance -- such as fire or grazing -- actually increased the success of yellow starthistle far more in non-native than in its home regions.

    Science

  • When exposed to increased carbon dioxide, precipitation, nitrogen and temperature--all expected results of climate change--yellow starthistle in some cases grow to six times its normal size while the other grassland species remained relatively unchanged.

  • Yellows starthistle may expand in California and Nevada as the climate changes while spotted knapweed moves toward higher elevations and spreads in Montana, Wyoming, Utah and Colorado, the study showed.

  • Specifically, the researchers concluded that climate change is likely to expand invasion risk from yellow starthistle in California and Nevada -- and lands currently occupied by invasive populations of the weed in California, Oregon and Washington are unlikely to become unsuitable for the species; hence, they have low potential for restoration.
