Join the effort to document the amazing diversity of Mount Diablo State Park during our weeklong celebration of California Biodiversity Day. Choose your trail(s) and go out bioblitzing (collecting pictures of living things) anytime during the week of Sept. 7-15. If you upload your observations to iNaturalist, they will automatically be added to the California Biodiversity Week project for the park. Deer, squirrels, birds, butterflies, dragonflies, lizards, snakes, spiders, trees, lichen, flowers, and more are here...what will you see? How many species can we find?
