New California Waterfowl Tracker website launched to help poultry producers assess bird flu risk

Circles on the California Waterfowl Tracker map shows where waterfowl are feeding and roosting. Red indicates a high density of birds, orange is medium density and yellow is low density.

To reduce potential exposure to avian influenza, a new interactive website is now available to help California poultry producers, backyard poultry enthusiasts, regulators and risk managers assess the locations of waterfowl relative to poultry farms in the Central Valley.

While not all waterfowl carry avian influenza, the migratory birds are the primary reservoir of the virus that kills chickens, turkeys and other birds and can take an economic toll on the poultry industry. During an outbreak of a highly pathogenic strain of avian influenza in 2014-15, nearly 50 million birds had to be killed to contain the disease in the United States.

“Avian influenza is such a devastating disease, in an abundance of caution, we want to limit any interaction between waterfowl and domestic poultry,” said Maurice Pitesky, UC Cooperative Extension poultry specialist.

The California Waterfowl Tracker has been developed by Pitesky at the School of Veterinary Medicine at UC Davis, the University of Delaware, U.S. Geological Survey and UC Agriculture and Natural Resources to show where waterfowl are.

From September through March, geese, ducks and other waterfowl migrate by the millions via the Pacific Flyway and winter in California wetlands, rice and corn fields. At the height of migration, the Central Valley is home to 3 million waterfowl.

Migrating waterfowl stop at Yolo Bypass. UC Davis research has shown that 5 percent to 20 percent of waterfowl carry avian influenza.

The Central Valley is also home to the majority of the state's commercial egg-laying hens, broiler chickens and turkey flocks.

Using the web app to understand when and where waterfowl are feeding and roosting, poultry farm managers and other stakeholders will be able to consider waterfowl in their decision making. They may decide to place pasture-raised poultry in a region of the state that has less wetlands, such as Fresno. If a large number of Canada geese take up residence nearby, poultry owners may decide to move their domestic birds indoors to reduce their exposure until the migrating waterfowl move on.

Using a machine-learning approach developed by Jeff Buler, University of Delaware wildlife ecology professor, the web app produces a waterfowl density map of California's Central Valley that is automatically updated daily with both satellite and weather station information.

“The model doesn't tell us whether waterfowl are carrying avian influenza, but it helps poultry producers and regulators understand where those interfaces could happen,” Pitesky said.

By law, organic and cage-free production must give birds access to the outdoors. While they are outdoors, poultry are at a higher risk of exposure to diseases carried by wild birds.

Additional waterfowl habitat and next-generation radar analysis of waterfowl are integrated into the web app. Users can search one or more addresses to anticipate their farms' interaction with waterfowl. Based on the proximity of waterfowl and wild bird monitoring information from the U.S. Fish and Wildlife Service, poultry owners can make biosecurity decisions.

“While the current version of the website is designed for California, the long-term goal is to develop and expand this system for the continental U.S. to promote health and safety of poultry flocks nationally,” Pitesky said.

To use the California Waterfowl Tracker, visit the UC Cooperative Extension Poultry website http://ucanr.edu/sites/poultry. A video of Pitesky demonstrating how to use the web app can be viewed at https://youtu.be/EOO0Q_ggZ9I.

Poultry producers who would like to be notified by UC Cooperative Extension if there is an avian influenza outbreak in their area can sign up on the California Poultry Census page at http://ucanr.edu/sites/poultry/California_Poultry_Census.

California Plant and Soil Conference convenes in Fresno Feb. 6-7


The state's top agricultural scientists will gather in downtown Fresno Feb. 6-7 for the American Society of Agronomy, California Chapter, 2018 California Plant and Soil Conference.

The conference comes at a key time for the California farmers and allied industries.

“There has been a flurry of new state regulation in recent years that the industry must contend with, increasing the needs for grower certification and training,” said Dan Munk, irrigation and soils advisor for UC Cooperative Extension in Fresno County. “Never before has grower education and training been more critical for irrigated agriculture in the state.”

The conference will be held at the DoubleTree Hotel & Fresno Convention Center, 2233 Ventura St.

At 9:30 a.m. Feb. 6, California Secretary of Agriculture Karen Ross opens the event by providing her thoughts on how California agriculture can move forward given recent droughts, floods and increased environmental restrictions as well as increased grower reporting, certification and compliance requirements.

Following Ross's remarks, three speakers will discuss timely topics at the intersection of water and nutrient management. The speakers are:

Patrick Brown, UC Davis
Topic: Barriers to the adoption of recommended nutrient and water management practices

Sarah Beganska, UC Santa Cruz
Topic: Addressing groundwater recharge with an eye to water quality

Tim Hartz, UC Davis
Topic: Irrigation effects on nitrogen efficiency

The remainder of the two-day conference contains 12 sessions, presented by scientists from the University of California, UC Cooperative Extension, Fresno State, Oregon State, NASA, USDA and industry. Session presentations are slated to cover nutrient management, emerging technologies for improved crop management, pest management, site-specific management, soil biology and soil health, sustainable use of water, applied crop management and managing farm energy.

More information and the complete agenda are available on the conference website, http://calasa.ucdavis.edu/

Federal grant to fund preservation of UCCE history


An ongoing effort to collect, digitally preserve and share 100 years of historical records by the UC Cooperative Extension (UCCE) has earned the UC Merced Library a more than $300,000 grant.

“We're extremely proud to be able to further the work already begun on the UCCE project,” UC Merced Chancellor Dorothy Leland said. “Our library is producing a collection that demonstrates the organization's lasting effects on the state, the work it has done in the past and its potential for the future.”

The work is especially relevant to the San Joaquin Valley, said Emily Lin, the UC Merced Library's Head of Digital Curation and Scholarship.

“We have a lot of archives and historic records based around urban centers, but we haven't been collecting the records of rural California in any systematic way,” she said. “But rural California has had an incredible influence on the state's history. California was transformed by agriculture over the past century.”

A four-year pilot archive project begun after the UCCE centennial in 2014.

The Archivist of the United States approved the $308,900 grant from the National Historical Publications and Records Commission for “A Century of Impact: Documenting the Work of the Cooperative Extension in California's Counties.” The three-year project will begin in the summer, after Lin and others hire a group of undergraduate students to help with the work. Additionally, the project will be part of an informational booth at the World Ag Expo in February in Tulare — UC Merced's first appearance at the exposition, which draws more than 100,000 people from all over the world.

“We were convinced the history of Cooperative Extension in California was worthy of preserving when we launched the pilot project four years ago,” said Glenda Humiston, vice president of UC Agriculture and Natural Resources (UC ANR), the organization that oversees UCCE. “The federal grant to continue this work confirms the value of UCCE history and its contribution to California's prosperity.”

A pilot project, begun after the 2014 centennial of the UCCE, looked at Merced, Ventura and Humboldt counties' UCCE records, and produced a stack of material 70 linear feet long — just for Merced County. A banker box is about 1 linear foot.

Records from Humboldt County included disaster responses from the 1955 and 1964 historic floods, while Merced County's records were mainly about crops, irrigation, the beginnings of the Merced Irrigation District and 4-H. Each county's records provide insight into its unique characteristics, Lin said.

The new project will collect 100 years' worth of reports and historic photographs from 20 California counties — in the Valley, along the coast, up north at the edges of the Sierra and along the southern border — and will geocode all the records.

“This project is of great potential value in supporting a number of lines of existing research, as well as in opening up new and fruitful areas of inquiry into the interrelated topics of democracy, technology and community,” said David Campbell, a political scientist and the associate dean for social/human sciences in the College of Agricultural and Environmental Sciences at UC Davis. He wrote a letter of support for the project that was included in the application.

The digitization project will help researchers at all levels, Professor Mario Sifuentez said.

“It provides access to a trove of documents that shed light on the nature and development of agriculture in the region, which amazingly has been understudied,” he said. “Despite living in the heart of one of the most productive agricultural regions of the world, few people really understand how agriculture in the Central Valley works. I am invested in producing work and helping students produce work that explains the historical trajectory of how the Valley ended up as ‘The Valley,' and agriculture is the main component of that story.”

The archives set the stage for many research projects across many disciplines. Historians will find the records helpful, but so will people studying progressive era institutions, immigration, race relations, social movements, technological change or the rich history of food and agriculture in California, Campbell said. There are also implications for political science and public policy scholarship; environmental and climate studies around such topics as water and pesticide use; material for economists and labor market scholars; and geographers.

The library is working with the San Joaquin Valley Historical Society, and San Diego State University will also have a set of the records digitized when the project is completed. In addition, regional 4-H students will be part of the project, helping tag and digitize the material.

Cornell University Professor Scott Peters, a historian of higher education who wrote a letter of support for the project, said engaging with local students and their families through a 4-H project is particularly valuable.

“It's always important to help young people connect with the history of their communities,” Peters said. “These historical materials will enrich their understanding of the vision, values, ideals, tensions, dilemmas and struggles that the work of building a democratic culture in partnership with higher education requires and involves. And it helps them understand their own role in history and ask themselves what they are creating and leaving that will be part of history 100 years from now.”

After the 2014 centennial, UC ANR allocated funds to locate a professional archivist at the UC Merced library, which is becoming known for creating comprehensive digital collections of historical materials.

Archivist Lisa Vallen began work with the three pilot counties. She found UCCE records in the National Archives as well as pictures, negatives and documents spread throughout the state.

“Ideally, historical records should be kept in a space that's climate controlled,” Vallen said. “In Ventura, they have some in a container on a farm. That's not ideal at all.”

The ANR hopes this project will help not only researchers, but will educate the public and policy makers about UCCE.

“There's no question about the value of this project and the richness it brings to the whole state, not just UC,” said UC Merced University Librarian Haipeng Li.
