L.A. BioBlitz Challenge

bioblitz challenge

Join the L.A. BioBlitz Challenge this summer (June 7 - August 7) to photograph and map animals, insects and plants found in your neighborhood, local parks, off of hiking trails, and in other natural areas.

Los Angeles is located in a global biodiversity hot spot and has an incredible array of native insects, animals, plants and ecosystems to explore. We need your help to better protect and understand where different species of plants and animals live across the City by uploading observations to iNaturalist. Every time you do, especially in observation cold spots in the map, you contribute to the knowledge about the City’s biodiversity that supports protecting and conserving local wildlife and their habitats.

Attend Neighborhood Science programs and read from the BioBlitz book list about Los Angeles wildlife for a chance to win prizes and earn the Summer Reading Challenge’s L.A. BioBlitz Badge.

Get Started


Download the iNaturalist app from Google Play or the App Store and create an account.


Get outside! Observe the wildlife around you. Check the indicator species cards below and challenge yourself to observe these species in the wild.

Explore observation cold spots near you and log observations in them to help researchers understand which species live there.


Upload your observations to the L.A. BioBlitz Challenge project.

Watch the video to learn how to record your first observation.

Complete the Challenge

To complete the challenge, upload at least 10 observations of plants and animals—including 3 or more indicator species—to the L.A. BioBlitz Challenge project on iNaturalist.

When you complete the L.A. BioBlitz Challenge you qualify for an exclusive prize drawing. You earn an additional drawing opportunity when you record observations from observation cold spots.

Submit a completion form online or drop off your completed game card at your local library through Monday, August 9 to be entered into the opportunity drawing.

Turn the Map Green

The heat map shows observation hot spots in green, and cold spots in gray. Help turn the entire map green by uploading observations to iNaturalist from observation cold spots.


Indicator Species

The City of Los Angeles is particularly interested in knowing where certain indicator species are found. When indicator species are present it typically means there is high quality habitat. Most of these species (e.g., mule deer, great horned owls) are typically dependent on natural areas and are mostly found in parks and in large areas of open space. However, if you are lucky, you might be able to see some of them, like bumblebees and monarch butterflies, in your backyard or neighborhood. Other indicator species, like the red-winged blackbird, are typically found in or near streams, rivers, lakes, and other water bodies. The indicator species cards below indicate where you are likely to spot certain species. Your observations of indicator species will be extremely important to City staff and local scientists studying biodiversity. How many of them can you observe this summer?
