Recently legalized recreationally in California, cannabis agriculture offers a unique opportunity to study and promote agroecology, particularly in northwestern California where many farms have small footprints and are located within and contain habitat for sensitive and protected species such as the Northern spotted owl, coho and Chinook salmon, and Humboldt marten. The cannabis industry, however, has a reputation for being extractive and contributing toxicants to wildlife and the environment, but many small-scale cannabis farmers are actually incredible land stewards, promoting and facilitating biodiversity on their farms and utilizing sustainable integrated pest management and other strategies to reduce their impacts to the environment. This presentation will highlight biodiversity research and projects occurring on licensed cannabis farms in Humboldt, Trinity, and Mendocino Counties carried out by Cannabis for Conservation, the only nonprofit focusing on supporting biodiversity on and through licensed cannabis farms. The cannabis industry in California will also be discussed, with emphasis on the continued potential to collaborate with farmers to support the environment, as well as the financial and regulatory hurdles faced by licensed small-scale farmers.
