Bitterbrush density in a known-parameter population was estimated using 19 different variations of quadrat and plotless sampling techniques. It was found that: (1) Many methods would not produce a correct answer with any size sample; (2) all methods required unreasonably large samples to attain acceptable precision; and (3) several methods required more effort than counting all plants on 1 to 2 acres. It is suggested that visual estimation techniques or nonrandom sampling methods may provide a more realistic approach to the density sampling problem.
