Help Participate in the California All-Taxa Biodiversity Inventory (CalATBI) by collecting soil samples from your own backyard!

California is one of only 36 biodiversity hotspots on planet Earth. The immense scale of California’s diversity means much of it remains unexplored, with thousands of species yet to be discovered. CalATBI is a specimen-based, DNA-powered effort to finally discover all of California’s biodiversity.

CalATBI efforts include conducting field work to find unexplored biodiversity, sequencing millions of specimens to build a DNA barcode reference library, developing next-generation technologies to accelerate discovery, and preserving biodiversity specimens and samples for the benefit of future generations.

Our goal is to save our precious biodiversity today, for tomorrow and always.

You can help by participating in our North Coast BioBlitz September 22nd through October 10th.
We are particularly interested in collecting soil samples from natural areas with native plant cover. Does that sound like your backyard or other private land you have access to with landowner permission? If so, please visit our to sign up!

This month’s Science on Tap is extra wild! 🦭 We’re thrilled to welcome Claire Nasr, M.S., Executive Director of the Trinidad Coastal Land Trust, for a lively talk all about marine mammals.
With more than 15 years of hands-on experience working with pinnipeds (that’s seals and sea lions!), Claire will spotlight the species that call Humboldt County home. Expect field stories, fun facts, and answers to those classic curiosities you’ve always wondered about. Claire’s scientific expertise—and her deep love for the North Coast’s wild places—make her the perfect guide for this ocean adventure. 🌊

✨ Doors open at 6 PM! Arrive early to snag a seat and sip a local brew from Paskenta Mad River Brewery while you settle in.

💙 All donations support Science on Tap and in-stream restoration projects by the Eel River Watershed Improvement Group—thank you for helping keep these events going strong!

☀️ The weather’s looking nice, so dress comfortably—sunhat and shades encouraged. And if you can, carpool with friends (parking is limited).

Science on Tap fosters collaboration among local advocates for natural resources. Let's create a platform for sharing ideas and inspire resilience in environmental restoration for generations to come. Join us in building an inclusive space that welcomes everyone into the environmental community, making knowledge accessible and enjoyable for all in a laid-back and fun setting. See you there!

Friday, September 26 at 6 p.m. Northtown Books welcomes Bridget A. Lyons to present her new book Entwined: Dispatches from the Intersection of Species.

Entwined is a collection of fourteen original essays by Bridget Lyons, a traveler, explorer, and former wilderness guide who has encountered countless animals and plants in their native environments.

Set in locations ranging from Alaska and California to Mexico and Honduras, Lyons’s stories are braided with careful observation, scientific research, and wonder to foster the connection between us and our nonhuman neighbors.

As readers travel through a diversity of ecosystems, they'll navigate icebergs in Alaska while researching the nesting strategies of common eiders, witness the apparent demise of a humpback whale on the Baja Peninsula while instructing a wilderness course, observe ibex while trail running the Alps, and contemplate the mystery of the octopus from a Cretan museum. Along the way, they'll be awed by the beauty, creativity, and intelligence of the natural world—and awakened to the reality of its shrinking biodiversity.

Join the Natural History Museum of Cal Poly Humboldt as we host Lorena Dominguez, a Biology student with Cal Poly Humboldt and the The North Coast Environmental Center For a Talk on Plankton. Drifters of Wigi: The Tiny Life Forms That Keep Our Bay Thriving. Explore how these tiny drifting organisms play a big role in the ocean. Learn about the importance of Citizen Science to protect and monitor Plankton in our bay. Friday Sept 26th, 2025 from 6:30-7:30pm.
This event is free, donations are appreciated. For more information visit our web site at natmus@humboldt.edu or call 707-826-4480
Talks are held in our classroom in the back of the Museum
