Noxious Invasive Plants

Weeds in Nevada County

The diverse regions of Nevada County allow niches for many invasive plant species to colonize. Noxious Invasive plants 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 invasive plants; their control expense is ultimately passed on to the consumer. Invasive plants affect everyone, either directly or indirectly.
