AZ Department of Agriculture Announces New Noxious Weed Regulations
Eleanor Gladding is a senior biologist and project manager in SWCA’s Tucson office. As a herpetologist and ecologist, her areas of expertise include endangered species habitat studies, revegetation planning, species-specific surveys, noxious weed issues, and wildlife-habitat relationships. She is adept at identifying plants and animals, their habitat, and signs of presence. She is also skilled at writing technical and non-technical reports and conducting the extensive literature research that accompanies writing at the professional level. Her duties as a biologist include study design, field studies and special-status species surveys, and report writing and editing.
On January 4, the Arizona Department of Agriculture (AZDA) officially adopted the revised Arizona Noxious Weed list. The main changes involve the classification of noxious weeds, as well as the addition and removal of species from the list.
Below are the new classification definitions:
These changes may affect your current or future projects in terms of adhering to the State of Arizona regulations regarding noxious weeds. Because species were both added to and removed from the list, your existing projects may require new inventories to determine whether all necessary species are being controlled.
Our experts can conduct noxious weed surveys and provide mitigation recommendations to avoid spreading or introducing noxious weed species in and around your project area. In addition, we can prepare noxious weed management plans for projects needing to control existing infestations.
