UC ANR scientists contribute to California’s Fourth Climate Change Assessment

>

The California Natural Resources Agency released California's Fourth Climate Change Assessment today (Monday, Aug. 27), at http://www.ClimateAssessment.ca.govUC Agriculture and Natural Resources scientists contributed substantially to the report.

The Fourth Assessment is broken down into nine technical reports on the following topics:

  • Agriculture 
  • Biodiversity and habitat 
  • Energy 
  • Forests and wildlife 
  • Governance 
  • Ocean and coast 
  • Projects, datasets and tools 
  • Public health 
  • Water 

The technical reports were distilled into nine regional reports and three community reports that support climate action by providing an overview of climate-related risks and adaptation strategies tailored to specific regions and themes.

The regional reports cover:

  • North Coast Region 
  • Sacramento Valley Region 
  • San Francisco Bay Area Region 
  • Sierra Nevada Region 
  • San Joaquin Valley Region 
  • Central Coast Region 
  • Los Angeles Region 
  • Inland South Region 
  • San Diego Region 

The community reports focus on:

  • The ocean and coast 
  • Tribal communities 
  • Climate justice 

All research contributing to the Fourth Assessment was peer-reviewed.

UC Cooperative Extension ecosystem sciences specialist Ted Grantham – who works in the Department of Environmental Science, Policy and Management at UC Berkeley – is the lead author of the 80-page North Coast Region Report.  Among the public events surrounding the release of the Fourth Assessment is the California Adaptation Forum, Aug. 27-29 in Sacramento. For more information, see http://www.californiaadaptationforum.org/. Grantham is a speaker at the forum.

Other UC ANR authors of the North Coast Region Report are:

  • Lenya Quinn-Davidson, UC Cooperative Extension area fire advisor for Humboldt, Siskiyou, Trinity and Mendocino counties 
  • Glenn McGourty, UC Cooperative Extension viticulture and plant science advisor in Mendocino and Lake counties 
  • Jeff Stackhouse, UC Cooperative Extension livestock and natural resources advisor for Humboldt and Del Norte counties 
  • Yana Valachovic, UC Cooperative Extension forest advisor for Humboldt and Del Norte counties

UC Cooperative Extension fire specialist Max Moritz contributed to sections of the main report on Forest Health and Wildfire and to the San Francisco Bay Area Report

UC ANR lead authors of technical reports were:

  • Economic and Environmental Implications of California Crop and Livestock Adaptations to Climate ChangeDaniel Sumner, director of UC ANR's Agricultural Issues Center 

  • Climate-wise Landscape Connectivity: Why, How and What NextAdina Merenlander, UC Cooperative Extension specialist 

  • Visualizing Climate-Related Risks to the Natural Gas System Using Cal-AdaptMaggi Kelly, UC Cooperative Extension specialist 
Dan Stark, staff research associate  for Humboldt and Del Norte counties, contributed to the pest section of Fuel Treatment for Forest Resilience and Climate Mitigation: A Critical Review for Coniferous Forests of California.

Weed Science is everywhere even on summer vacation!

Defoliated tamarisk, some willows coming up in the understory.

Heat is something that many Californians are used to, and live with for several months out of the year, but prolonged triple digit heat is not something I am used to in my corner of the state. Sure it gets hot up here in Lassen County, but there is most...

URGENT: Post Fire Research Opportunities at Hopland REC

>

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.

Research Opportunities

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.
  • Warehouses for storing equipment, a variety of accommodations from dorms to private houses
  • 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

Next Steps

  • 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
  • To register for either event follow this link: http://ucanr.edu/survey/survey.cfm?surveynumber=25451
