Are your birds safe from avian influenza?
Take UC's biosecurity survey to see how you score
Outbreaks of highly pathogenic avian influenza in January 2017 killed birds at commercial poultry farms and backyard flocks in the UK, China and South Korea. Thousands more ducks, chickens and other birds were culled to contain the disease. The outbreaks are spurring University of California scientists to develop more safeguards to protect U.S. poultry from avian influenza.
To prevent outbreaks of this highly contagious virus in the United States, commercial and backyard poultry owners are being asked to fill out an online biosecurity survey. UC Agriculture and Natural Resources and UC Davis researchers are studying poultry-raising practices to help strengthen the industry's defenses against avian influenza.
"With changing migration patterns of wild birds and global movements of poultry, there is an urgent need to develop plans to protect U.S. poultry against highly pathogenic avian influenza," said Beatriz Martínez López, director of the Center for Animal Disease Modeling and Surveillance in the School of Veterinary Medicine at UC Davis.
People who raise chickens, quail, ducks, turkeys, geese or other birds anywhere in the United States are invited to fill out the survey.
"We want to hear from all poultry producers: from the large commercial farms producing chicken eggs to the poultry enthusiasts who raise a few ornamental show birds in their backyards," said Martínez López, who is part of the University of California's Agricultural Experiment Station.
The survey asks which bird species are being raised and a few flock management questions. Is the flock is housed or kept outdoors? How often do you get new birds? What is the source of new birds? It also asks questions about location, such as the distance of the birds from ponds and other bodies of water that may attract migrating waterfowl.
Immediately after completing the online survey, participants receive a biosecurity score and recommendations to help them make more informed decisions.
"Each producer will receive their own biosecurity score and customized recommendations," Martínez López said. "Recommendations highly depend on the production system and we tried to adapt them to make the changes easier to implement for individual flocks."
The survey data will be confidential and only summaries will be made publicly available in research reports and peer-reviewed publications.
By analyzing biosecurity and management practices on poultry operations and backyard flocks, Martínez López and visiting professor Sharmin Chowdhury will be able to identify high-risk locations and time periods for avian flu outbreaks. The information will be used to develop biosecurity education programs for poultry farmers, backyard producers and poultry veterinarians.
The survey takes about 15-20 minutes to complete. To participate, visit http://bit.ly/2kkMycf by March 1.
This study is funded by Agriculture and Food Research Initiative Competitive Grant no. 2015–09118 from the USDA National Institute of Food and Agriculture.

Urban agriculture provides an excellent opportunity to integrate community development and youth empowerment while sharing information about growing food in diverse urban settings. In 2015 and 2016, staff from UC SAREP and UC Cooperative Extension partnered with youth participants and staff at non-profit agencies to offer youth-led tours of local urban farms.
This project gave youth leaders from 10 community-based urban ag organizations an opportunity to share their knowledge and experience with UC personnel, funders, policy makers, urban ag non-profit staff, and other urban farmers. Forty youth ranging from middle school through college age participated in a training on how to tell their personal stories related to urban agriculture before leading tours of their urban farms in the Bay Area, Sacramento and Los Angeles.
Videos documented these efforts, including a visit to young people farming in the Bay Area and a virtual farm tour with youth in Los Angeles. The videos show how powerful this experiential education is for both youth and adults, and how UC can continue to work effectively with our communities to build sustainable food systems.
Other organizations that would like to host a similar youth-led farm tour activity can access the curriculum and trainer's guide below. Funding from UC ANR and the UC Global Food Initiative made this project possible, along with the support of community partners including Community Services Unlimited, Social Justice Learning Institute, WOW Farm, Berkeley Youth Alternatives, Phat Beets Produce, Acta Non Verba, the Yisrael Family Urban Farm, The GreenHouse, the International Garden of Many Colors, Burbank Urban Garden, and Mutual Housing CA.

But suppose you miss some weeds that are starting to flower but the flowers aren't open yet? I think most growers will just pull or cut the weed and leave it in or near the field.
I want to show you a time-lapse video I took. I cut the flowering stem off of an annual sowthistle plant and took a photo with a special camera every minute for 6 days. As you can clearly see, even though the stem was no longer receiving water or nutrients from the soil, at least the flower bud continued to mature and produce seeds. Now, having said that, I have not germinated the seeds to see if they are viable, but there is a good chance they are. Click HERE for video. It's about 1 1/2 minutes long, but most of the action happens in the first 50 seconds.
So the take home message - if the weeds have flower buds starting to open, remove them to covered piles, trash cans, or other area where they will not be a source of new weed seeds.

Santa Clara County is among several California counties and cities now considering local implementation of AB 551, the Urban Agriculture Incentive Zone Act, which became state law in 2014. Once enacted at the local level, AB 551 offers a potential tax reduction for land owners who lease their land for urban farms and community gardens. At this point, San Francisco has the only such zone. On February 10th, 2015, the Santa Clara County Board of Supervisors took the first steps toward creating urban agriculture incentive zones. Interested cities within the county would also need to implement the measure.
There's plenty of interest in San Jose, Santa Clara County's largest city, where urban farm advocates hope that implementing AB 551 would allow small-scale urban agriculture to be viable in an urban area where land values are high. Garden to Table is one of the community groups leading the local push for AB551. They hope that improving access to land for urban growers will also enhance options for access to local foods.
Garden to table staff developed a report on the implementation of AB551 that may be of interest to groups in other counties and cities around California (see link below for the full report). They used census track and property tax data, general plan designations, and more to analyze suitability of land for a potential urban agriculture incentive zone. Thanks to support from The Health Trust, Garden to Table is embarking on a second research phase for adopting AB 551 in San Jose and Santa Clara County. Over the next year they hope to build a network of property owners and urban agriculture organizations, and collect data about interest from community members.

The spatial needs of successful public space include a strong neighborhood connection, an accessible perimeter, and a site design and layout that promotes many and diverse users. Communally-managed urban farms benefit from similar spatial considerations: strong connections to neighborhood context insure a strong community commitment to the demanding maintenance needs of a production landscape, strong physical and visual accessibility promotes diverse users of the site, and flexible layouts and designs encourage diverse programs within the site. The consideration of the communally-managed urban farm site as a whole, and not parceled into individualized plots, allows for the use of smaller and more constrained urban sites and a greater shared commitment to the entirety of the site. This can help lessen one of the consequences of a shared public and production landscape: theft. While perimeter fencing might be a requirement of other forms of urban agriculture, a communally-managed urban farm is more resilient to the impacts of leaving a site open and accessible to the public. In addition, the accessibility of the site can lead to a higher volume of volunteer participation, consistent maintenance and good overall site appearance, and a strong sense of ownership by surrounding community (including those not interested in urban farming). Thus, although often perceived as an incompatibility, this investigation reveals that an open site perimeter, as well as the other spatial considerations of a successful public space, are consistent to the design of a successful communally-managed urban farm.
