The rich soils and moderate climate of Monterey County make it an ideal place for invasive weed species to colonize. Invasive weeds are usually able to out-compete local native plant species for water and space because they are more prolific, have more vigorous growth, and lack predators that would otherwise help to keep them in check. They degrade habitat for other wildlife, domestic animals, recreation, and other land use activities. The agricultural industry is particularly affected by weeds; their control expense is ultimately passed on to the consumer. Weeds affect everyone, either directly or indirectly.
