Reporting an Invasive Plant
- Record the plant’s location as exactly as you can (GPS coordinates, if possible), the date you saw it, and an estimate of how many there were. Include the site’s landowner or manager, if known.
- Take some identifying photos, especially clear extreme closeups of flowers and/or leaves from different angles. The more the better.
- If you take a sample, place it immediately into a sealed bag, then press it between paper when you getb home.
- To avoid spreading the plant, check your clothing and shoes thoroughly before leaving the area, and remove and bag all traces of seeds.
- Post a record of the observation on Calflora.org (preferred) or iNaturalist.org, or both. OCCNPS monitors these sites almost daily.
- Alternatively, report the find immediately to .
OCCNPS will take it to the next essential step: Rapid Response
- Confirming the species, possibly field checking and mapping the colony, and collecting a herbarium sample.
- Alerting the appropriate land manager and/or stewardship group and facilitating a management response.
- The management may be done by the land manager's staff and/or stewardship program, and/or via a contractor.
- On-going surveys and management may also be established.
OC’s native plants, and their lands’ managers, thank you!
