On this specific occasion, the team worked in the South African themed garden and helped with weeding of invasive plants. The horticulturist was very informative, highlighting each of the various types of animals that live throughout the Botanical garden, and how South African plants and trees have spread all across San Francisco since they were first introduced.

There is a fee to volunteer, however, all fees contribute directly to the cost of materials, tools, training, and of course project management. We thank @SanFranciscoBotanicalGarden for the opportunity to give back to the community.
