Please bring your field guides if you have them (we will have copies of Mt.

Mushroom BioBlitz at Luginbuhl Headwaters Preserve
2025-10-30 10:00 - 14:00 | Luginbuhl Headwaters Preserve, 2100 Deetz Rd, Mt Shasta, CA, 96067
DATE CHANGED TO THURSDAY, OCTOBER 30 DUE TO WEATHER… Join Siskiyou Land Trust and local mycologist, Jayme Castro, on our first MUSHROOM BIOBLITZ at Luginbuhl Headwaters Preserve. Come and be a part of this important Citizen Science event!
Jayme Castro, founder of the Mt. Shasta Mycological Society, will be our guide. We will be spending the day hiking and documenting as many mushroom species as we can using the iNaturalist App*.

A BioBlitz is a community science event where people of all experience levels team up to record as many species as possible in a short time.
Your observations help build a record of local fungal diversity and support conservation efforts for this unique habitat.
Using iNaturalist, your photos become part of a global database used by scientists and land stewards.
It’s a fun way to learn, share discoveries, and connect with others who love mushrooms and nature.
Bring your smartphone with the iNaturalist app*, and if you’d like to collect specimens, a small knife, basket, tackle box, or wax paper are helpful for keeping mushrooms separated and protected.
Some collections may even be selected later for DNA sequencing to help identify rare or unknown species — a great way to contribute to fungal research!

Registration is required. Please click here to register
*Please review these photo tips from iNaturalist prior to the day of the BioBlitz to ensure the highest quality data collection: https://www.inaturalist.org/posts/3531-documenting-mushrooms
