Celebrate California Biodiversity Days at Whiskeytown
Sunday, September 14, 9 AM
- Shasta Environmental Alliance is pleased to host its third annual BioBlitz event to celebrate California Biodiversity Days. Join SEA Board Member Juliet Malik and fellow California Naturalist Holly White-Wolfe at Whiskeytown for a day of observing and documenting the many plants, fungi, animals, and insects that call this national recreation area home, via an iNaturalist BioBlitz.
We welcome people of all ages to come out and help us reach a goal of finding at least 30 species in honor of California’s 30×30 initiative to conserve 30% of California lands and coastal waters by 2030 through collaborative action. Have fun learning how to identify the life around you while helping to steward and protect California biodiversity! By joining this challenge you are participating in citizen science, and observations you make in our region will be counted toward a state-wide goal of mapping at least 30 species. Your observations will be used to help understand biodiversity, track its changes over time, and direct conservation actions.
Expect to walk at least two miles. Wear hiking shoes, a hat, and sunscreen, and bring plenty of water and a lunch for after. The trail we have chosen is rated as moderate, has a steady incline, and the terrain is uneven. We will return from the walk by 11:30 AM for a lunch break and group discussion of what we observed and were able to identify. Please no dogs except service dogs on a leash—this helps us better observe living creatures.
Prepare for the event:
- REQUIRED: Register for the event and sign the SEA waiver form here to receive directions to the meet-up spot. Also be sure that you have signed the Shasta Chapter CNPS waiver above (see opening paragraph). Children under the age of 16 must be accompanied by an adult.
- Download the app on your phone and click “Join” to sign up for free: start here. Familiarize yourself with how it works. Check out Getting Started: iNaturalist for tutorials.
- Join the CA Biodiversity Week Challenge 2025 so that all of your observations will be included in the project.
- Contact juliet@ecoshasta.org if you have questions!

Brokeoff Mountain
Saturday, September 20, 8 AM
- The Brokeoff Mountain Trail is said to the hardest hike in Lassen Volcanic National Park. It is 7.5 miles out-and-back with a 2,500-foot elevation gain. This will be an end-of-summer hike to test your endurance and to see and identify plants that are able to withstand the high-altitude climate around 9,500 feet. We will be botanizing on the trail, so it will be a moderately paced hike, but you should only participate if you have been doing regular hikes all summer. Expect great views of the Sacramento Valley and the Battle Creek Watershed. Bring plenty of water, a hat, sunscreen, lunch, and hiking poles. Dogs are not allowed in the Park. Limited to 12 people. Email field trip leader David Ledger at dsledger49@gmail.com to reserve a space and get the meeting place. Be sure that you have signed the waiver above (see opening paragraph).
