5-year ERRP findings featured in Mendocino Observer

In their September 6th, 2018 issue, the Mendocino Observer discussed the 5-year findings report from the Eel River Recovery Project (ERRP)’s algal survey of the Eel River watershed. In collaboration with UC Berkeley, particularly former UCB grad student Keith Bouma-Gregson, the ERRP deployed 332 cyanotoxin monitoring devices in the Eel  from 2013-2017. They found that cyanotoxin-a levels were highest in the South Fork Eel River during most years, and that low flows and high air temperatures contributed to an early start and increased colonization of harmful cyanobacteria. To read more, see this copy of the 9-6-18 Observer and/or visit the ERRP website at www.eelriverrecovery.org

Eel River Recovery Project Findings Featured in News

Findings from the Eel River Recovery Project (ERRP) were recently featured on the front page of the Mendocino County Observer. The ERRP have performed yearly surveys of non-native Sacramento pikeminnow populations in the South Fork Eel River from 2016-present. Working with UC Berkeley students Phil Georgakakos, Wes Slaughter, Taylor Schobel and Sage Kurnie along with Dr. Brett Harvey of the US Forest Service Redwood Science Lab, the 2018 survey found that the 2013-2015 drought has led to an uptick in large adult pikeminnow, and management of these populations is recommended in order to protect native salmon, steelhead, and others.

2019 Carol Baird Graduate Award for Field Research- funding opportunity

The Berkeley Natural History Field Stations invite applications for the  “The Carol Baird Graduate Student Award for Field Research.”  Awards will be granted to graduate students to support high quality research that is carried out primarily in the field, based in or around Berkeley’s Natural History Field Stations:

Angelo Coast Range Reserve

Blue Oak Ranch Reserve

Hastings Natural History Reservation

Point Reyes Field Station

Sagehen Creek Field Station

The second competition will support field research beginning in 2019.  Proposals of up to 5 pages (total), describing the project, its importance, and proposed methods and logistics, must be submitted electronically to fieldstations@berkeley.edu by September 30, 2018 with “Carol Baird Graduate Student Award for Field Research” in the subject line.  

Awards of up to $22,000 will be made on the basis of merit.  Funding may be requested for a single field season or multiple field seasons, and for work at or around a single or several reserves.  Support allocations (amount per student, potential for renewal) are flexible, as long as the research is field-based, is of excellent quality, and is substantially improved by this support.  

Further guidelines for proposal preparation can be found at http://fieldstations.berkeley.edu.

Recent paper by Rempe and Dietrich on rock moisture featured by NSF, SF Chronicle

Daniella Rempe and Bill Dietrich’s recent paper, “Direct observations of rock moisture, a hidden component of the hydrologic cycle” is receiving press on the NSF News website, the San Francisco Chronicle, ScienceDaily, and other news organizations. Their study, conducted at the Eel River CZO, monitored rock moisture from 2013-2016 at nine wells across a hillslope underlain by a thick weathered bedrock zone. They found that this bedrock can be a water source for trees even after the soil has become parched during the dry season, suggesting that rock moisture should be incorporated into hydrologic and land-surface models used to predict regional and global climate.

Research at Angelo- Dr. Sarah Kupferberg

Dr. Sarah Kupferberg’s research is focused on food web ecology, amphibian population biology, and conservation of aquatic ecosystems in California. A particular interest of Dr. Kupferberg is the effects of dams and diversions on the physical and biotic conditions for wildlife. To investigate these issues, she conducts field research and experiments in rivers with hydroelectric projects, drinking water reservoirs, and flood control projects. Dr. Kupferberg is also applying her extensive knowledge of aquatic ecosystems at the policy level, reviewing stream restoration plans and working with engineers to facilitate designs that are compatible with hydraulic and biological needs.

Angelinos and Eel River Recovery Project volunteers have worked together with Dr. Kupferberg to count (and rescue!) egg masses of Foothill Yellow-legged Frogs (Rana boylii).  R. boylii lay their eggs at traditional oviposition sites in the river every spring.  The size of tennis to soft balls, these black-speckled jelly masses are more conspicuous than the adult frogs. What do you notice first in the photo below?

Conveniently for biologists interested in conserving this species (which is currently under review for protection by the Federal and California Endangered Species Act), adult females lay one clutch of eggs each spring. So one egg mass = one breeding female frog.  A census of clutches thus provides an index of the total size of the breeding population. Repeating the counts annually can indicate if populations are growing or declining. In the case of the Angelo Reserve, the population has fluctuated over the last 25 years, but remains basically stable. In contrast, since 2012 we have been observing a growing population along the banks of the South Fork Eel- this is where the California State Parks stopped operating the Benbow Dam in 2016 to impound the river and create a summer lake.  In the Spring of 2016 in advance of the de-construction of the Benbow Dam, ERRP volunteers (http://www.eelriverrecovery.org/) and Angelinos relocated 100’s of egg masses (10,000’s of thousands of tadpoles!) out of harm’s way. Now that the high flows from winter 2017 have reconfigured the gravel bars at the restored dam site, we will monitor how the frogs respond.

The Willits Hub Fish & Aquatics Restoration Day

Sarah Kupferberg, Bill Dietrich, and Mary Power participated in a Fish and Aquatics Day celebration as a kickoff of the “Willits Hub” on Sunday, March 19th 2017.   The Willits Hub is being launched as a meeting place and headquarters for several non-profit environmental groups in the Willits area, including the Eel River Recovery Project.

Pat Higgins (ERRP’s Managing Director) invited Sarah to give a talk on her 20+ years of research on Rana boylii, i.e. the Foothill Yellow-legged Frog, a native frog that breeds in the Eel River.  Bill talked about the Critical Zone (the thin, water-exchanging skin of the Earth between the top of the vegetation and the bottom of the weathered bedrock beneath the soil) and why the geology of this zone matters for water storage and resilience to drought in the forests and grasslands along the California North Coast.  Mary told a bit about the history of the Angelo Reserve—the stories of the Angelo-Steel families who protected this land, and some of the adventures that students and scientists have had in studying its creatures, plants, soils, river food webs, and landscapes. In addition, Pat gave brief talks about sediments and river bugs, and Park Steiner reported on his very long-term studies of chinook carcass trends in the upper mainstem Eel and Tomki Creek.  A meeting highlight was the remarkable footage shown by filmmaker Shane Anderson as a preview of his forthcoming movie about the Eel: “A River’s Last Chance”.

We felt fortunate to meet old friends and new ones at the Willits Hub who share our concern over the future of the Eel River ecosystem, and look forward to future get-togethers, some at the Angelo Reserve!
