Pest & Weed Management

The East Bay Regional Park District (Park District) is the largest landowner in the East Bay and manages a diverse landscape in Alameda and Contra Costa counties. The Park District comprises 125,000 acres in 73 parks, 55 miles of shoreline, and over 1,300 miles of trails for hiking, biking, horseback riding, and environmental education. The Park District receives more than 25 million visits annually.

Managing the large scale of open space within the Park District’s jurisdiction requires strategic planning and effective practices. A specific focus of the Park District’s land management is the control of pests and diseases in a sustainable and ecologically principled way, utilizing scientific, evidence-based best practices. The Park District’s Integrated Pest Management (IPM) program plays an important role in maintaining healthy ecosystems that benefit wildlife and provide positive experiences for park visitors.

IPM Methods:
The Park District uses a variety of methods as part of its IPM program, including

  • Cultural – Mulching, burning/flaming, grazing, and competitive planting with native plants.
  • Mechanical – Weeding, line trimming, mowing, hand pulling, grubbing, etc.
  • Biological – Utilization of natural or introduced enemies of the identified pest.
  • Chemical – Use  of organically registered (OMRI) and conventional products to control plants, insects, fungi, or other pests. In all publicly accessible locations, chemical application(s) are posted 24 hours in advance and remain posted for 24 hours after application.
Glyphosate (Commonly Referred to as Roundup):
In 2019 the Park District Board of Directors voted to ban glyphosate use in developed park areas* by the end of 2020. The Park District does NOT use glyphosate near picnic areas, play areas, or water fountains.

IPM Goals:

  • Protect Public Health – Managing ticks, E. Coli and Harmful Algal Blooms
  • Ensure Fire Safety – Controlling vegetation around potential ignition sources including campgrounds, maintaining building perimeters and meeting safety standards for fire protection.
  • Improve Ecological Function – This includes restoration and enhancement of sensitive habitats and promoting biodiversity
  • Manage Healthy and Safe Forests – Reduce risk of catastrophic wildfire. This might also include managing for pathogens like Sudden Oak Death.
  • Promote Safe & Enjoyable Use of Park Features and Trails – Maintaining recreational use on all paved trails and trail access as well as maintaining vegetation for roadway line of sight and clearances around infrastructure.
