My name is Valentina Evans, and I am a new volunteer at the UC Hopland Research and Extension Center. My partners Benjamin Evans, and Zane Petersen have chosen to volunteer with me at the HREC for our senior project at Ukiah High School. A few weeks ago on the twenty-first of December we volunteered to help two researchers, Paulo who studied at UC Santa Cruz, and Wyath, who is still studying at Humboldt State University, to plant acorns from different ecosystems, and analyze how they will adapt to conditions with more water, less water, more sunlight or a lack of sunlight. This study is part of Dr. Blair McLaughin's study from the Zavaleta Lab at UC Santa Cruz.
We started off by digging holes about 1 foot deep and laying a thin square piece of chicken wire at the bottom of the holes to prevent gophers from entering and eating the acorns. We then took a circular strip of chicken wire and placed it on top of the flattened piece at the bottom. With the second strip of chicken wire standing horizontal, we continued by covering the holes with the same dirt we originally dug out. Now with the metal secured in place, Paulo came around and gently placed the acorns inside of the holes. The hands-on experience was extremely fascinating, not to mention peaceful. The view at the top of the hill was breathtaking, and the weather was just perfect. The entire process was tiring, but having had the opportunity to participate in a lab/research project made the whole experience worth it.
Although the project will not produce any data until the acorns sprout, the idea behind the project is captivating. Paulo and Wyath are studying the growth of oak trees from all sorts of climates, locations, and ecosystems. Some of the acorns are from northern California and others from way down in southern California. They will be monitoring the water levels, and amount of sunlight the oak trees will receive, all in hopes to see how the oak trees will adapt to different changes in their environments. Seeing as how I want to major in Biological Sciences in college, this experience was exceptionally informative for me and has taught me how critical patience, effort and time are in order to successfully accomplish a lab and receive the most accurate facts. I am very grateful to have been able to participate in this ongoing project and am looking forward to continuing to be a part of the younger generation who can benefit from having the Hopland Research and Extension Center available to us, to further our knowledge about the environment.
HREC and Post-Fire Research Opportunities
What is HREC?
The UC Hopland Research & Extension Center (HREC) is a multi-disciplinary research and education facility in Mendocino County located in the foothills of the Coast Range about two hours north of Berkeley. As part of the UC system for over 65 years, we are stewards of more than 5,300 acres of oak woodland, grassland, chaparral, and riparian environments. Elevation at the center ranges from 500 ft to 3,000 ft. HREC currently maintains a research flock of about 500 breeding ewes that have been the subjects of numerous studies on ranching practices, range management, livestock nutrition, wool production and breeding. Field experiments and demonstrations conducted here since 1951 have led to more than 1,500 publications in animal science, entomology, plant ecology, public health, watershed management, and wildlife biology. Our website is hrec.ucanr.edu.
The River Fire
As part of the Mendocino Complex fire, the River Fire burned through HREC on the evening of July 27 and into July 28. Approximately 3,000 acres of our center burned in this fire. Due to the concentrated efforts of Center staff and Cal Fire crews, all of our employees, residents, sheep, livestock dogs, offices and residences were saved. Below please find the burn map of our property. All of the black area to the north was burned and the dark red patches were areas of vegetation that remained unburned. The fire intensity varied greatly as did oak survival. You will see two smaller burned areas in the southern part of the property that were prescribed burns performed in June of this year.
While this was a blow to current research, pastures, and water infrastructure, we also see this as a wonderful opportunity. Due to extensive historical data sets and ongoing research projects, coupled with a variety of grazed and ungrazed pastures, and prescribed burn plots for comparison with wildfire, there is enormous potential for pre- and post-fire studies in the fields of:
- Watersheds and hydrology; fire science; plant science; soil science; entomology and parasitology; wildlife and wildlife ecology; rangeland management; grazing practices as fire suppression…..
To support this research, HREC offers:
- A well maintained network of roads that accesses almost all parts of the property, vehicles to use.
- A fully equipped shop staffed by employees skilled in fabrication and repair of research equipment
o Electrical, wood working, welding and metal fabrication, mechanical
- Skilled staff trained in field work techniques, with long histories of successful research support
- Fiber optic internet with Wi-Fi access throughout headquarters, strong cell service in most areas
- A vault of raw data, photos, and final papers from research conducted at HREC.

- Wet and dry lab space (undergoing renovation during fall 2018, available spring 2019)
- Lysimeter with available watering system, electrical connections, and fiber optic access point
- A research flock of sheep consisting of just under 500 breeding ewes, with all needed facilities and RFID tracking
- Fenced pastures and biological reserve areas for different treatment plots and controls
- A fully equipped conference facility with A/V equipment and fiber optic connections
- Zoom meeting on September 7th, 10am. More in depth information, Q&A.
- Field day on October 19th, 10am-5pm. Presentations, brainstorming, Q&A, site tours, available accommodations

Acorns are dropping from the mighty oaks at the UC Hopland Research and Extension Center (HREC) – marking a time to celebrate the 5,358 acres of oak woodland and rangeland at the facility.
On Oct. 15 the doors to the center will open, inviting the public to join scientists and staff as they enjoy the fruits of the season with a farm-to-table luncheon, live bluegrass music and an oak-inspired silent auction. Funds from this event will support educational programming at the site.
The event offers the community the chance to learn about the research being conducted and enjoy the best in local produce.
“From 10 a.m. to 12 noon there will be optional field tours of some of our key research projects, where visitors can meet the scientists, see what tools they use and what they are learning about our environment,” said Hannah Bird, community educator at HREC.
Participants can choose from four field experiences, including large mammal wildlife research using the latest in drone technology with UC Berkeley researcher Justin Brashares to a relaxed visit in the vineyard tasting Mediterranean wine varietals with UC Cooperative Extension viticulture advisor Glenn McGourty. A stroll with the HREC director will offer a visit to the Shippey Hall, woodworking and mechanic shops, lambing barn and greenhouse to experience a slice of the diversity of research, outreach and teaching offered on the site.
A three-course luncheon runs from 12 to 3 p.m. and includes presentations from HREC director Kim Rodrigues, live bluegrass music from local band “Gibson Creek” and the silent auction.
“We've been so grateful to all those who have offered artwork, jewelry, food and oak woodland experiences for this silent auction,” Bird said. “I'm going to struggle not to bid for them all myself.”
Auction items include gorgeous oak paintings, a stunning oak table made by Ben Frey, a dinner and farm tour with Magruder Ranch and a family science adventure kit focused on our woodlands, alongside books, posters and photographs.
Funds raised at the event will support the creation of a new nature trail to Parson's Creek, which cannot currently be safely accessed during school field trips.
“We are now offering many more opportunities for the public to visit our site. More than 500 K-12 students and 2,000 community members visit annually, yet we cannot currently access the creek safely,” Rodrigues said. “This trail will open up great opportunities for riparian educational activities with our local students.”
Tickets cost $65 for adults and $15 for children.
or by calling Hannah Bird at (707) 744-1424, Ext. 105. The registration deadline is by October 11. The event will be at the Rod Shippey Hall, 4070 University Road, Hopland.
Due to the nature of the research with sheep and a commitment to using guard dogs as part of a predator control program, no dogs are allowed on UC ANR HREC for public events.
More on our speakers
Justin Brashares, Ph.D., is an associate professor at UC Berkeley in the Department of Environmental Science, Policy and Management. His focus areas include
the catastrophic global decline of biodiversity widely recognized as among the most pressing problems we face as a society. His research attempts to understand how consumption of wild animals and conversion of natural habitats affects the dynamics of animal communities and the persistence of populations. Work in his group extends beyond traditional animal conservation to consider the economic, political and cultural factors that drive and, in turn, are driven by, changes in wildlife abundance and diversity. Through these efforts, his group strives to propose empirically based, interdisciplinary strategies for biodiversity conservation.
Glenn McGourty is the UC Cooperative Extension viticulture and plant science advisor for Lake and Mendocino counties. He received a bachelor's degree in botany from Humboldt State University in 1974 and an master's degree in plant soil and water science from the University of Nevada, Reno, in 1979. McGourty joined UC Cooperative Extension in 1987, and works with winegrape growers, wineries, nurseries, landscapers and vegetable growers. Present research activities include evaluating 14 Mediterranean winegrape varieties; clonal trials of Sauvignon blanc, comparison of organic, biodynamic and conventional farming for their effects on winegrape and soil quality; and evaluation of cover crop species.
Prahlada Papper is an educator and naturalist as well as a graduate researcher at UC Berkeley in David Ackerly's ecology lab. His research at the Hopland Research and Extension Center involves the genetic and ecological diversity of California oaks. Papper doesn't really expect to find answers to the age old mysteries of oaks, but does think that by using modern tools like genome sequencing and ecological models, we can look at some of the old questions in new ways.
Kim Rodrigues, Ph.D. is the director of the Hopland Research and Extension Center. She began her UC career with Cooperative Extension in 1991 as a forestry and natural resources advisor for Humboldt and Del Norte counties. She became the county director two years later. Her research and extension activities have focused on environmental policy and engagement of the public in resolving environmental conflicts. Her experience, coupled with a great passion for HREC's 5,300 acres of oak woodland and a keen desire to reach out to the community to encourage collaboration and partnerships, offers new opportunities and exciting times at HREC./span>

A little late in the month, but here is our August newsletter!
And more about our upcoming "Hopland Hikes" event:
"Over 5,300 acres of oak woodland, chaparral and rangeland will be opened up on Saturday, September 12th from 10am-12pm for a guided public hike at the Hopland Research and Extension Center. Dr. Kim Rodrigues the Center Director will guide visitors on a 2 hour hike and share some of the exciting research and education activities, how the public can get involved at the site and where bears like to bathe!
This black bear has been captured on trail camera, enjoying a break in one of the water troughs at HREC, during a study conducted by Dr. Justin Brashares which examines how wildlife movement is affected by fencing.
“The Hopland Research and Extension Center (HREC) is one of 9 centers across the state owned by the University of California Agriculture and Natural Resources division. This is a great opportunity for the public to visit the site and learn about the important research that has been conducted here over the last 60 years. Research projects have encompassed many different disciplines ranging from Dr. Bob Lane's groundbreaking research into Lyme disease and other tick borne diseases to Dr. Donna Gillette's work on ancient petroglyph style markings on the site, found to be over 5000 years old! This is a great opportunity for the public to visit this beautiful property, we are also hoping to build a community of docents to help run these hikes on a monthly basis in 2016. There is so much to see on the site we can't cover it all in just one hike!” Commented Hannah Bird, Community Educator at HREC.
Participants are encouraged to wear clothing suitable for hiking whatever the weather and to bring a water bottle. Hikes will take place on roads or trails – but terrain may be steep and uneven at times. No dogs are allowed on the hike due to the presence of guard animals on the site used for sheep protection.
Those who would like to share a potluck lunch after the hike are encouraged to bring along plates, utensils, cups and an item of food to share.
This is a free event but participants are encouraged to sign up in advance at: http://ow.ly/R9BJo . Hikers will meet at the Rod Shippey Hall, 4070 University Road, Hopland CA 95449 at 10am on Saturday, September 12th.
