What creatures are thriving at Gateway Arch National Park? Citizen scientists like you can help us figure it out!
Join us on the final day of National Park Week, Sunday, April 28, 2024, from 10 to noon for our first-ever BioBlitz. Use your cell phone and the free app iNaturalist to take pictures of birds, insects, arachnids, and other creatures you see throughout the park. Your data will help the park, St. Louisans, and others know what creatures are where.
Meet at the registration table outside the entrance to the park beginning at 9:30 AM to check in and learn how to get started.
