LOMPICO POND RESTORATION & DEMONSTRATION PROJECT

Invasive Vinca Purge Restores Pond Habitat

February 24, 2024 • Lompico Pond Workday

This month, our pond volunteers/restoration ecologists focused on removing invasive, non-native Vinca Major, Forget-Me-Nots, and Tradescanthia from the land adjacent to the northern edge of the pond. Vinca (aka periwinkle) is one of the most common (and awful) invasive ground covers in the San Lorenzo Valley.

Big periwinkle spreads rapidly, especially in riparian areas, creeks, and drainages. Once established, big periwinkle forms a thick ground cover, choking out native plants and changing the area’s ecology. Particularly bad infestations can alter local hydrology*.

Because Vinca is so harmful to wetland areas, it has been a primary focus of the pond’s restoration efforts. Last year, Vinca was removed from the area between the pond and Lakeshore Drive, and we are happy to report that there has been almost no regrowth! As Vinca can sprout from small stems and root fragments, it is essential to remove it entirely and put it in the trash.

Removing Vinca will allow the small native sprouts (such as hedge nettle, redwood sorrel, and our native ferns) to grow and flourish.  We look forward to observing the results of this habitat restoration and, hopefully, improvement in pond water quality.

*Hydrology refers to the natural flow and movement of water; severe Vinca overgrowth can negatively impact water drainage, absorption, and quality in the pond's local environment.
