As urban coyote numbers rise, the animals are increasingly crossing paths with residents. There have been police reports of coyotes attacking pets and even people, but there has been no place to report casual coyote encounters. Now there is a new mobile app to help keep track of where those wily coyotes are coming into contact with people. Hikers and people walking their dogs can use Coyote Cacher, created by the University of California Agriculture and Natural Resources, to report coyote sightings.
“I'm so excited about this app because it will help us to collect better information on coyote conflict in California,” said Niamh Quinn, UC Cooperative Extension advisor, who studies human-wildlife interactions. “Coyote conflict appears to be particularly high in Southern California and it seems to be emerging in other areas. The information people provide through Coyote Cacher will help inform government agencies, wildlife researchers, park managers and residents to make better coyote management decisions.”
By reporting encounters with coyotes in their neighborhoods, residents can share information to help neighbors keep their pets and children safe.
“There is a coyote encounter map that will allow the public to keep track of what is happening in their areas,” said Quinn, who is based in Orange County.
Individuals can use the app to check a map to see locations of coyote sightings. Pet owners may decide not to let their pets out at night unsupervised in areas where coyotes have been reported.
“The app allows users to sign up for email alerts,” Quinn said. “These alerts – green, yellow and red – notify users when there is a coyote encounter reported in their zip code.”
Green is the lowest alert level and will give alerts for all coyote encounters in the user's zip code, from sightings to a person being bitten. Yellow will not alert users about sightings, but will let them know about all levels of pet interactions, including pets being chased or attacked off-leash by coyotes, and red alerts. Red is the highest alert level and allows for users to be informed only about the more serious incidents, for example, a coyote attacking a pet on a leash or biting a person.
“This app will also allow me to gather baseline information on coyote activity and the success of community hazing,” Quinn said.
Community hazing involves people shouting and waving their arms at coyotes and generally being obnoxious to make the nuisance animals afraid of humans.
“It would be great if everyone would do this when they see a coyote, but at the moment this is not really happening,” Quinn said. “Also, coyotes in Southern California appear to take a lot of risks and come in close contact with humans so community hazing may not deter them.”
More intense hazing, like shooting them with paintball guns, might be more effective techniques for government agencies to manage urban coyotes, she said.
To find out if any of these techniques work, the UC wildlife scientist would like to put collars on urban coyotes to study whether the animals move away from locations after hazing.
“We are seeking funding to collar coyotes to find out more about their activity and social structure and how they react to different types of management,” Quinn said. “We would need to figure out if the effects of the hazing are long-lasting, or if the coyotes just revert to ‘bad behavior' when the hazing is stopped.”
Although Quinn's research is focused on California, Coyote Cacher can be used anywhere in the United States. The website also offers information about urban coyotes.
Coyote Cacher can be used on a computer or on a mobile device at http://ucanr.edu/CoyoteCacher.
The Coyote Cacher app was designed by UC ANR's Informatics and Geographic Information Systems and funded by UC Cooperative Extension in Orange County.
Coyote Cacher's map shows locations of coyote encounters. Green dots are the lowest level alert, yellow indicates a pet interaction and red, the most serious, warns of an attack on a pet on a leash or person.

“Mendocino County supports many ranchers and our communities enjoy locally produced lamb, beef, milk, cheese and other agricultural products,” said Kimberley Rodrigues, director of UC HREC. “Along with these opportunities come challenges associated with living alongside some of our resident wildlife. The workshops will help local residents deal with these challenges.”
Rodrigues – who has a doctorate degree in environmental science and has been a leader in outreach, strategic facilitation and partnership development for 25 years – has been actively involved in wildlife management at the 5,300-acre HREC since she arrived in mid-2014.
“I quickly realized the biggest challenge to maintaining a sustainable flock of sheep here in our location is addressing predation issues, primarily by coyotes,” Rodrigues said. “With some improvements to our fences, changes in pasture rotations and increased use of guard dogs, losses of sheep to coyotes are now at an acceptable level. We hope to share our own experience, hear from diverse perspectives and experiences at these events and would like HREC to become a hub for future learning on this topic.”
Recent discussion and decisions made by the Mendocino County Board of Supervisors regarding their contract with USDA Wildlife Services (WS) and their use of an integrated wildlife damage management program prompted UC HREC to provide a space for two workshops to allow learning on wildlife management and community conversation.
The Dec. 1 workshop will focus on scientific design and is implemented by USDA WS. It provides an opportunity to hear experts from USDA, the Californi Department of Fish and Wildlife, UC Cooperative Extension and Defenders of Wildlife to discuss the most up-to-date research in wildlife behavior and non-lethal control methods.
The Dec. 2 community conversation workshop is hosted by UC HREC and includes current research from UC Agriculture and Natural Resources, wildlife biologists and discussion of the challenges associated with ranching in Mendocino County from the Magruder family and other local ranchers. The day will culminate in discussion groups on topics ranging from integrated wildlife management tools to understanding local, state and federal connections.
The public may attend either day or both days. Registration for the two workshops is separate.
“Topography, surrounding environments, community viewpoints, available funds and the kind of animals being farmed are all part of the picture – there is no easy solution,” said Hannah Bird, UC HREC community educator. “Ranchers and land managers need to know what tools are available to them and the implications and benefits of each of these tools. Attending both workshops will provide a deeper understanding of the issues.”
Community members, ranchers, land managers and members of non-profit organizations are invited to attend. The workshops will be at the Rod Shippey Hall, Hopland Research and Extension Center, 4070 University Road, Hopland, CA 95449. Registration is $30 for each day (including lunch) and must be made in advance. The registration deadline is Nov. 23. Space is limited.

Timm's career has focused on managing wildlife damage and providing science-based advice for people to solve conflicts between humans and wildlife, which increasingly arise as both human and wildlife populations expand. One of his research subjects was finding better ways to prevent coyotes from preying on sheep.
He compiled, edited and published the reference book “Prevention and Control of Wildlife Damage” in 1983 and co-edited the 2004 revision. Since 1989, he has served in many leadership roles on the Vertebrate Pest Council, including managing editor of the Vertebrate Pest Conference Proceedings since 2002.
In 2007, Timm planned the first Urban Coyote Symposium and published papers from the symposium as a management guide. He also created the website CoyoteBytes.org to provide current, science-based management recommendations to wildlife managers and decisionmakers at the city, county and state levels who were dealing with urban coyote conflicts.
As director of the Hopland Research & Extension Center, he was instrumental in the design and construction of Rod Shippey Hall, an outreach and research facility that was completed in 2012. The late Rod Shippey was a UCCE advisor in Mendocino County.
Timm earned a B.S. in biology at the University of Redlands and master's and Ph.D. in ecology at UC Davis. He began his career at the University of Nebraska at Lincoln, where he served for nine years as Cooperative Extension vertebrate pest specialist and assistant professor. In 1987, he returned to California to become the second administrator in the history of the “Hopland Field Station,” as it was then known. The late Al Murphy served as the center's first administrator from 1951 to 1986.
In retirement, Timm and his wife Janice plan to stay in Ukiah and spend more time gardening, fishing, traveling and attending Giants games. Timm, who has been granted emeritus status, also plans to finish several publications and continue participating in the Vertebrate Pest Council.
