Community science is a huge part of the TWBY, and you can participate by uploading photos of the plants you find in the Tahoe region to joining our iNaturalist Project, found here: https://www.inaturalist.org/projects/tahoe-wildflower-big-year-2022
Through this effort, we are able to document the plant community of the area, providing occurrence data that can be critical to resource management decision-making. And these data really add up - during the 2019 TWBY, participants provided over 13,000 spatially and temporally explicit records of over 1000 species of plants!
For those unfamiliar with iNaturalist, Bob Sweatt presented a terrific webinar on using the platform for the TWBY earlier in the year, a recording of which can be found here: https://www.youtube.com/watch?v=CqRug7YONcQ
iNaturalist also offers many video tutorials here: https://www.inaturalist.org/pages/video+tutorials
