Vegetation Mangement Guidelines

Our Vegetation Management Guidelines have been developed to help San Mateo County Park staff make informed decisions for future vegetation management priorities and actions. In addition, they provide user-friendly “how to” advice to park rangers, volunteers, and others to help select vegetation management actions that are most effective.

Position on Herbicide Use

The San Mateo County Parks Natural Resource Management team is dedicated to improving habitat and protecting biodiversity within our parks. To curb the spread of invasive plants that have greatly altered many of California's natural plant communities we employ many techniques, such as biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties, but when these techniques prove ineffective or economically infeasible, chemical methods are an important tool in our management toolkit. When we do use chemicals, we do so in accordance with established guidelines and in a highly targeted manner that minimizes risks to human health.
