Early detection and rapid response to new infestations can save many dollars and help maintain the health, diversity, and functionality of our ecosystems. We urge readers to consult other resources and local experts to help determine the most appropriate management methods for their areas. Sixty-seven plant species are included in this booklet, with brief descriptions, photographs, information on what areas they invade, where they are currently located in New Mexico, and some general information on management.
This booklet focuses on helping land managers, farmers, homeowners, recreationists, and others identify troublesome weeds found in New Mexico because early detection is critical for effective weed management. In agricultural and rangeland settings, these weeds can cause severe economic impacts by decreasing crop yields and lowering available forage for range animals, resulting in a decrease in livestock health. While these impacts are species-specific, weeds have been documented to cause the following: displacement of native plants and animals, increased fire danger, increased soil erosion, increased flood severity, increased soil salinity, and decreased water quality. These weeds are tough competitors and can spread rapidly, creating large stands that can persist for many years in the environment and cause many negative impacts to our ecosystems. Weeds pose a serious and increasing threat to New Mexico’s environment and economy.
