Citizen Science

How can you have fun while simultaneously contributing to science? By joining the global citizen science movement. The Museum, independent naturalists, and outside organizations have created numerous citizen science projects aimed at helping scientists better understand the species that exists in any given region at any given time. Take part in the projects below at any time throughout the year to contribute to the exploration and creation of scientific knowledge. Your observations help create a better understanding of our region for generations to come.

Border BioBlitz 2020

Join staff and volunteers from The Nat at Border Field State Park on Sunday, March 29 to kick off the Border BioBlitz, which takes place throughout the month of April. This community science effort is intended to record as many species as possible along the U.S.-Mexico border in order to document the stunning biological diversity of the borderlands. Learn more.
