Density of Carduus and Cirsium Thistles in Selected Areas of Maryland

  • Philip W. Tipping (a1)

Abstract

In a three county area, the density of musk thistle was higher than plumeless thistle in pastures in the easternmost county, equivalent in the central county, and lower in the westernmost county. Bull thistle was detected frequently, but density was always low. Detection of Canada thistle decreased from east to west.
