Description: This case study documents temporal and spatial squarrose knapweed (Centaurea virgata Lam. spp. squarrosa (Willd.) Gugler) seed dispersal from study sites in central Utah. Felt seed traps were placed along transects extending from sites occupied by squarrose knapweed into adjacent plant communities. Seed dispersal from knapweed plants occurred over an 8-month period. By 1 November 1999, 50 and 53 percent of dispersed seed had been recovered at the Knight and Cherry Creek locations respectively. By May, nearly all seed has dispersed from the producing plant. Most seed was deposited and remained within 2 m of the parental plant.

Keywords: wildland shrubs, disturbance, recovery, fire, invasive plants, restoration, ecology, microorganisms
