The San Lorenzo River Urban Wilds Project, which I administer with my Santa Cruz Critter Club, is a citizen science effort cataloging the biodiversity of the levee-bound lower San Lorenzo river, a wildlife corridor through the heart of downtown Santa Cruz, California.

Over the past seven years we have collected over 1400 photographic observations from over five dozen contributors, representing 340+ different species and counting.

Contributing to this database, and our knowledge of the flora and fauna of the downtown river, is as simple as joining iNaturalist and using their website or smartphone app to submit your observations to the SLRUW project.

Guided by this citizen science data, I have also designed and published a preprint of “A Field Guide to the San Lorenzo River Urban Wilds”.
