*Sites not treated with herbicides. Numbers are not included in Summary Total or Percent

Target weed species have significantly decreased on all sites treated. Sites which show astatic (no significant change in frequency) result have a very low composition of the weedspecies present and were most likely missed with spot treatment methods.

Grass, forb and tree/shrub species have increased or remained static in frequency by 83%,70% and 73% on treated sites respectfully, while target weed species have decreased infrequency by 85% on treated sites.

Grass species include annuals, such as cheat grass, which are invaders to the site. A downwardfrequency for these species would be desirable.
