Wyoming BioBlitz

Wyoming's annual community science weekend extravaganza! | July 23- 25, 2021

Tickets for Wyoming BioBlitz 2021 are sold out, but you can add yourself to the waitlist here.

In-person Wyoming BioBlitz is back! This year it will be held at The Brinton Museum in Big Horn, Wyoming, on July 23- 25, 2021. Discover a Wyoming gem, survey wildlife, and have a blast with your family and friends!

The Wyoming BioBlitz is a free, one-of-a-kind opportunity for families, students, and all nature-lovers to learn about plants and wildlife and help scientists survey them. During this weekend-long event, participants will team up with biologists to search for and document as many plants and animals as possible at The Brinton Museum. 

New this year is a service project. Participants will plant 75 to 100 young cottonwood and willow trees along Little Goose Creek on the Quarter Circle A Ranch (home of The Brinton Museum).  Due to extensive browsing by herbivores like white-tailed deer, seedlings from native trees struggle to grow into mature trees here. Help us improve the health of this ecosystem by planting tree saplings and protecting them from browsing with fencing!

Also new this year are optional pre-BioBlitz workshops that will be held on the afternoon of July 23. After registering for BioBlitz, you will be sent a link to register for the pre-workshops. Be sure to open your confirmation email!

You can also participate virtually here.

Why Participate in Wyoming BioBlitz?

If you’re reading this, you probably already know how fun and exciting it is to notice new or uncommon species around you. Wyoming BioBlitz feeds that sense of curiosity and discovery by encouraging people to observe everything around them, from the moose to the millipedes. By dedicating some time to looking for new species, you’re also likely to learn about wildlife you didn’t even know about.

Wyoming BioBlitz is also a great opportunity for nature-lovers of all backgrounds to spend time together doing something out of the ordinary. No level of expertise is needed, which means people of all ages can enjoy a weekend of exploring nature and the biodiversity in it.

Participating in Wyoming BioBlitz also contributes scientific data that are useful to scientists and conservationists working to study and protect Wyoming’s wonderful plants and wildlife.

Finally, Wyoming BioBlitz provides a hands-on opportunity to learn from experts. Participants will meet local scientists and learn how they study their subjects. Teachers can also receive two Professional Standards Teaching Board (PTSB) credits for participating.

We are planning to hold Wyoming BioBlitz in-person this year due to the declining coronavirus cases, increasing vaccine ability, and outdoor setting of this event. We will be monitoring the situation as the date approaches, and we will ultimately follow Wyoming’s health recommendations. If you are uncomfortable with attending in-person, we hope you’ll participate virtually.

PTSB Credits

We offer two Professional Standards Teaching Board (PTSB) credits for teachers participating in Wyoming BioBlitz. To receive credits, you must be a PTSB-certified teacher, sign up for the credit by contacting Dusty Downey (, 504-453-4124), and participate in all activities during the event.


1. What types of surveys will there be?

The types of inventory activities will depend on the species that the scientists are trying to find and document. Different groups will look for birds, fish, plants, invertebrates, mammals, microbes, fungi, etc. Some will be land-based; others will require wading in shallow water. You can view the full schedule here.

2. Who can participate?

Everyone! Children can participate in inventory activities, but they must be accompanied by an adult. There will also be activities just for children. Teachers can earn 2 PTSB credits. 

3. If I have a mobility issue such as using a wheelchair, can I still participate?

Yes, although many of the survey teams will be on trails that may make participation challenging.

4. What should I wear?

You will be outside and in the field, so you should dress accordingly. Layering is highly recommended to make you most comfortable. You should also bring a hat, sunglasses and sunscreen to protect you from potential sun exposure. Wear sturdy shoes if you plan on using the hiking trails.

5. What happens if it rains or there is bad weather?

Nature happens despite the weather. Wyoming BioBlitz will take place rain or shine.
