What is a BioBlitz?
A BioBlitz is a fun outdoor event where people work together to find and record as many plants, animals, and insects as they can in one place and in one day. Using the free iNaturalist app, participants take photos of what they discover and share them with scientists and nature experts. These observations help researchers learn more about the plants and animals living in our area while helping people connect with nature.
No experience? No problem! Whether you’re a curious beginner or a seasoned naturalist, you’ll receive guidance and training to get started.
