January 2009 HERBACEOUS WEED CONTROL 0B PRACTICE INTRODUCTION 1B USDA, Natural Resources Conservation Service―Practice Code 315 HERBACEOUS WEED CONTROL 2B Protect soils and control erosion Herbaceous weed control is the eradication, Reduce fire hazard reduction, or manipulation of herbaceous weed Plans must include post-treatment measures as species including invasive, noxious, and prohibited 4B needed to achieve the management objective. plants. Environmental hazards and site-specific application criteria listed on pesticide labels and in PRACTICE INFORMATION 3B approved pest management references must be Herbaceous weed control is designed to achieve followed when chemical control measures are the desired plant community through the utilization applied. Treatment methods should be applied in a of Integrated Pest Management (IPM) principles. manner that minimizes the potential for smoke, This is accomplished by mechanical, chemical, chemical drift, or other unintended impacts to air biological, or a combination of these techniques. resources. Herbaceous weed control is applied to accomplish one or more of the following: COMMON ASSOCIATED PRACTICES 5B Herbaceous Weed Control is commonly used in a Restore native or create desired plant Conservation Management System with practices communities such as Nutrient Management (590), Prescribed Manage noxious woody plants Grazing (528), Prescribed burning (338), Forest Enhance accessibility, quantity, and Stand Improvement (666), and Upland Wildlife quality of forage Habitat Management (645). Maintain or enhance wildlife habitat For further information, refer to the practice including habitat for threatened and standard in the local Field Office Technical Guide endangered species and associated job sheets and specifications. The following page identifies the effects expected to occur when this practice is applied. These effects are subjective and somewhat dependent on variables such as climate, terrain, soil, etc. All appropriate local, State, Tribal, and Federal permits and approvals are the responsibility of the landowners and are presumed to have been obtained. Users are cautioned that these effects are estimates that may or may not apply to a specific site.

These symbols indicate only an increase (+) or a decrease (-) in the effect upon the resource, not whether the effect is U beneficial or adverse. The diagram above identifies the effects expected to occur when this practice is applied according to NRCS practice standards and specifications. These effects are subjective and somewhat dependent on variables such as climate, terrain, soil, etc. All appropriate local, State, Tribal, and Federal permits and approvals are the responsibility of the landowners and are presumed to have been obtained. All income changes are partially dependent upon market fluctuations which are independent of the conservation practices. Users are cautioned that these effects are estimates that may or may not apply to a specific site.
