Sacramento County Weed Management Area


The Sacramento Weed Management Area Memorandum of Understanding (MOU) establishes the terms and conditions under which the WMA collaborates and coordinates activites necesary to prevent the introduction, establishment, and spread of harmful invasive weeds in Sacramento County. These activities focus on prevention, detection, and management of priority invasive weeds.

The MOU fosters interagency cooperation with federal, state and local agencies, watershed-based groups and private landowners in activites that contribute to the stated objectives.


Strategic Plan Mission & Vision:

The Sacramento County WMA will reduce the introduction and spread of invasive weeds through coordination and cooperation between signatory groups. The WMA will focus on preventing introduction of new weeds and stopping the expansion of existing populations through control and education projects.


  • Protect and enhance the native biodiversity of Sacramento County ecosystems.
  • Maintain and increase the profitability and value of cropland and rangeland.
  • Maximize the effectiveness of vegetation management activities and reduce the cost of roadside, park, and waterway maintenance.
  • Enhance the recreation experience throughout the County.
  • Reduce fire hazard and fire control costs in the County.
  • Encourage research and coordination on effective weed management techniques.

Strategies for Accomplishing Goals:

  • Education: Raising Awareness and Outreach
  • Prevention: Exclusion and Early Detection
  • Information Management: Survey, Inventory and Mapping
  • Projects: Weed Management, Restoration, Monitoring and Research
  • Administration: Project Funding, WMA Administration and Partnerships

  • Coordinate land management groups to more effectively manage weeds
  • Hold one field meeting per year

  • Laguna Creek Watershed Weed Management Program
    • Tamarisk, Chinese tallow, pampassgrass, giant reed, water hyacinth, milk thistle and yellow starthistle were removed from six locations within the Laguna Creek Watershed by volunteers and professionals. Weed mapping was extended to include the Upper Laguna Creek Corridor. Additionally a weed monitoring training workshop was conducted for the Elk Grove Unified School District and local scout group leaders.
  • Robla Creek Mapping & Weed Removal
    • Initiated in 2008, this project targets the removal of mature and seedling red sesbania infestations throughout Robla, Magpie and Steelhead Creeks. In addition, volunteer removed over one million seed pods within these waterhsheds in just two years.
  • Effie Yeaw Nature Center Weed Reduction
    • This project focused on removing weeds from two-acres surrounding the Effie Yeaw Nature Center. Weed removal in this area improved wildlife habitat, increased the Nature Center's ability to educate the public about natural environments and reduced the threat of wildfire for the Nature Center.
  • Merten Ranch yellow starthistle control
    • 100 acres of yellow starthistle were treated using a helicopter herbicide application, in a cost-share between the owner of Merten Ranch and the Sacramento WMA.
  • American River Parkway
    • The WMA funded the purchase of weed removal tools like weed wrenches for weed removal work on the American River Parkway. Weeds like yellow starthistle, red sesbania, and arundo were mapped using GPS and aerial photos. A controlled burn for yellow starthistle was also carried out. The WMA worked with the Sacramento Weed Warriors to complete the project.
