The effects of grasshopper herbivory and competition on threadleaf snakeweed plants were measured in the Bernalillo watershed in central New Mexico. Eight treatment combinations (protected vs. non-protected; control, elimination of threadleaf snakeweed plants only, elimination of grass plants only, elimination of both grass and threadleaf snakeweed plants) were applied to 480 two-year old threadleaf snakeweed plants. Over the two years of the study, stem counts and plant heights were conducted on two-year old snakeweed plants before and after grasshoppers were known to invade the site.
