Join Siskiyou Land Trust for the iNaturalist City Nature Challenge!

Help document the incredible biodiversity of Siskiyou County by contributing your observations to the iNaturalist app during this global community science event.

The City Nature Challenge (CNC) is the world’s largest community science project, and Siskiyou County is part of it! From April 24-27, 2026, every plant, animal, or fungust you observe and upload through the iNaturalist app will count toward our region’s total.

Whether you’re a seasoned naturalist or just curious about the world around you, anyone can participate. Explore your backyard, a local trail, or your favorite outdoor spot. Every observation matters.

This is also a great opportunity for classrooms, families, and visitors to get involved, with real-time results visible both locally and globally.

Klamath River Raft Trip

Marty Sochet navigates a raft full of excited nature lovers.

Registration is open!

Join us on Sunday, June 7th for SLT’s legendary Klamath River Rafting Trip! Made possible by a number of SLT supporters and experienced raft guides, this is a great opportunity for rafters of all levels to get out on the water for an easy afternoon float with the SLT community.

We’ll raft through the morning on a lovely class II-III (“easy”) section of the Klamath River from the Sluice Box launch outside Seiad Valley, to the Seattle Creek takeout spot, roughly 12 river miles. We will pass an SLT-conserved property on Thomspon Creek and will stop for a bring-your-own pack lunch along the way.

The requested donation of $100 per person will benefit the work of SLT, helping to protect the sacred waterways we will explore that very day.

Only one person can sign up at a time. Please add your name to the waitlist if the event is full. We hope to add more boats should there be sufficient interest.

All equipment and personal floatation devices will be provided. This will be a full day excursion.

See you on the water!
