Important caveats on plant collection:

CNPS promotes the ethical collection of plants with appropriate permits and landowner permission, for the purpose of documenting occurrences for herbaria. CNPS requests that no plants should ever be collected without landowner permission and/or required permits. Once permission is granted, we ask that trained individuals collect the plant(s) and deposit the specimen(s) in a major California herbarium. CNPS hopes to be able to offer short courses for volunteers in ethical plant collection.
