Not all scientists have degrees. Some are just regular folks, called citizen scientists, who help researchers collect data, sometimes with the assistance of smartphone apps. These everyday scientists will be hard at work at the Fall Plant Walk at the Montgomery Woods State Reserve in Ukiah, and they welcome new participants. Attendees are instructed to download Calflora’s phone app Observer Pro (for iPhone or android) before the hike and log in using their Calflora email addresses and passwords. Then during the relatively easy two- to three–mile journey, they will record their observations about, and take photos of, the plants they encounter. Walkers will meet on November 17 at 9 a.m. at the west side of the CVS parking lot in Ukiah and carpool to the park, where the hike will start at 9:45 a.m.; the event will end at 1 p.m. For more information, go to facebook.com/calflora.
