2024 Post Symposium Workshops
10 January 2024
Optional post-symposium workshops are scheduled for the Wednesday following the Symposium. You do not have to attend the Symposium to register for a workshop. To register for a workshop, visit the Registration Page.
Workshop 1: Soils, Landforms, and Vegetation of Big Chico Creek Canyon and Beyond
Instructors: Andrew Conlin, Soil Scientist, Chico Soil Survey Office, Natural Resources Conservation Service
Time: 8:30 a.m. – 3:00 p.m. (bring a lunch and hiking shoes)
Meet: Highway 32 Park & Ride (carpool to Upper Park Wildwood Avenue to parking lot at north side of 5-Mile bridge; commute time is approximately 10 minutes).
Location: Big Chico Creek Canyon & adjacent Cascade foothills, Bidwell Park
Cost: $25 (limit of 25 participants)
This trip begins in the floodplain of Big Chico Creek and travels back in time across the older deposits of the creek and up onto the Cascade foothills. The first route covers a condensed sequence of the major landforms that occur in the Sacramento Valley, as well as the transition to the Tuscan Formation in the Cascade foothills— in less than 1 mile. The second route is a 1.5-mile, one-way walk up the bottom of Big Chico Creek Canyon, applying what was observed on the first route and viewing the slot canyon in the Lovejoy basalt, which controls the stream dynamics in this reach of the canyon. Vegetation and habits will be correlated to soil characteristics and landforms along both routes. Understanding the relationship of soils, geologic landforms, vegetation and plants is essential to recognizing landscape features foundational to natural history study and essential to ecological habitat restoration and associated research.
This is a 6-hour (+/- ½ hr.) field trip.
Workshop 2: Heritage Growers Source Identified Native Seed Production Facility Tour
Time: 8:00 am – 12:00 pm (arrive at Heritage Growers at 9:00; bring a lunch for an hour-long post-tour chat & networking)
Meet: Highway 32 Park & Ride (commute time is approximately 1 hour; carpooling arrangements can be made at the symposium on Monday and Tuesday).
Location: Davis Ranches Farm Headquarters, 7681 Sycamore Slough Road, Colusa, CA 95932.
Cost: $25 (limit of 35 participants)
This field trip is a tour to the Heritage Growers source identified native seed production facility. It will cover all aspects of the numerous steps involved in the production of restoration appropriate native seed. The tour will include a visit to Heritage Growers’ demonstration garden where new ecotypes and new species are trialed, seed is produced for the nursery operation and small plot amplifications are implemented. We will also visit Heritage Growers’ production fields where more than 100 distinct species and ecotypes are produced over approximately 170 acres. Discussions will include methods for field establishment including direct seeding and plug installation, how fields are maintained including irrigation and weed control, how seeds are harvested including how large farm equipment such as swathers and combines are utilized to efficiently harvest seed at scale. The field trip will cover the seed conditioning (cleaning) process including how seeds are dried, the various methods used to clean seed and how the seeds are stored, tested, and retested. Woven throughout the fieldtrip will be examples of various Best Management Practices Heritage Growers use to maintain genetic integrity of different ecotypes.
This is a 3-hour tour that will also include an additional, optional, 1-hour lunchtime gathering where we will discuss source identified native seed issues, including the importance and advantages of selecting local ecotypes for ecological habitat restoration.
