Volunteers are an important part of the ongoing quality assurance process. If you are interested in wild plants in California, you are cordially invited to join this community. For instance, if you are aware of a plant growing wild in some park or other location where it is not yet shown on Calflora, we urge you to register as a contributor and to add an observation of that plant where you know it grows.  If it is an observation record that does not look right and you are a contributor, you can write a comment on the record. We pay attention to comments and answer emails, so what you see on Calflora is the product of the vigilance of many engaged users.
