The presence of 40 weeds was recorded on 130 sites from Lake Huron, Ontario, to Bangor, Maine. From the occurrence and abundance on these sites, an estimate of a weed's nuisance value was determined. Each site was analyzed for nine physical factors thought to influence the presence of these taxa. The preference of each taxon for each site factor has been recorded in a composite table. The presence of specific weeds as indicative of site conditions in abandoned pastures is discussed.
