Ring Mountain Preserve Sweet Fennel Project

Sweet Fennel (Foeniculum vulgare)

In 2009, the Open Space District began treating sweet fennel on Ring Mountain that has begun spreading into the main drainage area on the south side of the preserve. Our goal is to prevent the further spread of sweet fennel to preserve native biological diversity and promote wildlife habitat. Our strategy is to use Integrated Pest Management (IPM). This is an effective and environmentally sensitive approach to weed management that relies on a combination of common-sense practices. An IPM program uses current, comprehensive information on the life cycles of plants and their interaction with the environment to manage weeds by the most economical means, and with the least possible hazard to people, property, and the environment.

Sweet fennel (Foeniculum vulgare) is an invasive, non-native herbaceous plant that is spreading throughout California's grasslands
