2018 Redbud Field Trips

Castle Peak

All Redbud field trips are free and open to non-members as well as members. Unless stated otherwise, Redbud trips are easy, as we usually walk slowly and stop to view, identify, talk about, and enjoy each plant species. Most of our trips are led by at least one botanist.

Bring water, lunch/snack, sun screen, hat, jacket, rain gear, and hand lens, as needed. Children are warmly welcomed, but please arm them with a whistle! No pets are allowed on Redbud field trips (service dogs are permitted).

Ride sharing is recommended, as parking at most trailheads is limited. We also suggest riders share the cost of gas, perhaps giving $5 to the driver for under 40 miles round-trip, more if longer.  Field trips will be canceled if heavy rain (or snow) is predicted.

It is hard to predict when and where wildflowers bloom; wildflower displays may vary greatly depending upon weather patterns.  A cold, long winter means later blooms, while natives blossom earlier if March is warm and dry.   To see native plants at their best, field trip dates must be flexible.  Trip dates, times, and locations are posted as soon as scheduled; check this website and the Redbud Facebook page for updates.  For advance email notice of trips, sign up for the Redbud Yahoo Listserv (see Redbud homepage).

If you would like to lead a field trip or know a good destination, please email your write-up or suggestion at least 2 weeks before the scheduled date to and we will see that it gets announced.  The write-up should include: date and time, directions to meeting place, what to bring, distance and  length of time the walk will take, difficulty and elevation change if known, and what people may see and experience there.


Exploring Bryophytes of the Sierra Nevada Foothills
Field Trip Saturday, February 17, 2018
    When: Saturday, February 17, 2018
    Time: 10:00 a.m. to 2:00 p.m.
    Where: 17660 Pleasant Valley Road, Penn Vally
        Bridgeport, South Yuba State Park, Nevada County

What are Bryophytes?  Bryophytes are small, non-flowering plants that generally grow in large, dense colonies on trees, rocks, and soil. The most well-known are the mosses (e.g., sphagnum moss), but liverworts and hornworts are also bryophytes. These tiny wonders are best appreciated close-up through a hand lens.  Ecologically, Bryophytes play important roles in transforming barren areas by beginning the soil formation process, maintaining soil moisture and making nutrients available to other plants.

bryophytes-02What we will see:  Bridgeport features trails along the South Yuba River through grassy hillsides and patches of oak woodland including four species of native oaks, Bigleaf Maple, Blue Elderberry, Snowdrop Bush, and California Bay.  We’ll have opportunities to see Bryophytes in a variety of micro-climates and on a variety of host trees.

Redbud is very fortunate to have as our leader for this field trip Jim Shevock -- researcher, author, world expert on Bryophytes, and President of the Bryophyte Chapter of the California Native Plant Society.  Jim will be providing a guide to Bryophytes to participants.

  From Grass Valley, take Hwy 20 West to Pleasant Valley Road and turn right.  From Auburn, take Hwy 49 North toward Grass Valley. Turn left on Hwy 20 (west) and then right on Pleasant Valley Road. After about 7.7 miles, you will arrive at the marked parking area.  Parking is $5 and enforced regularly.

What to bring: Water, snacks/lunch, hat, sun and/or rain protection/gear, and hand lens.

jim-shevockAbout Jim Shevock:  Jim retired in 2009 from public service with a botanical career spanning more than 30 years between the USDA Forest Service and the National Park Service. He is currently a research associate and fellow at the California Academy of Sciences, Department of Botany and a research associate at the University Herbarium, UC Berkeley.  Initially a vascular plant taxonomist by training with a focus on the flora of the southern Sierra Nevada, Jim migrated to the study of bryophytes (primarily mosses) in the late 1990s. He is a co-author of ‘California Mosses’ which provides a portal into the wonderful diversity of California mosses with nearly 2,200 color images. His plant collections, just over 51,000 specimens, are housed at the herbarium of the California Academy of Sciences (CAS) with selected duplicates provided to major bryophyte herbaria around the world. Jim has 7 flowering plants and 6 mosses named in his honor included the moss genus Shevockia, endemic to China and Japan. Jim is the current President of the Bryophyte Chapter, CNPS.
