The document proposes a food forest design for a 2.25 acre site in McLaren Park in San Francisco. The design includes 3 guilds - a Coast Live Oak guild, a Black Walnut/Shellbark Hickory guild, and an Apple Tree guild. Each guild would feature multiple plant varieties selected for their functions like attracting insects/birds, fixing nitrogen, and providing forage and human food. The design aims to showcase multifunctional urban green space and involve the local community.
