An interesting example of how trained volunteers can work in protected areas is the Master Gardeners Program sponsored by the VanDusen Botanical Gardens Association in Vancouver, B.C. Before being accepted into this program, volunteers with a keen interest in gardening and with a willingness to share that interest and experience with members of the public must attend an information session and write an eligibility test.
