The term "weed" is often defined as a plant out of place. A. C. Martin has complained that this definition reflects human bias and that pest plants are out of place only with respect to man's immediate purpose. In nature's scheme, they often serve useful functions such as providing food for wildlife throughout the growing season and covering barren soil, thus preventing soil erosion. Judging from their competitive success with many so-called desirable species, they are anything but out of place.
