UC Master Gardeners partner with Alzheimer's San Diego in Reminiscence Gardening project

The UC Master Gardener Program of San Diego County has always been open to innovative ways of expanding its mission and passion for gardening into new parts of its community. The San Diego program has a rich history of successful partnering with other local organizations to reach under-served populations. An exciting new collaboration was unveiled in March 2018 when five UC Master Gardener volunteers took their newest public outreach project Reminiscence Gardening to the Alzheimer's San Diego's (AlzSD) social activities program.

Thirty participants, all community members being served by AlzSD, got their hands dirty and enjoyed a day of sensory stimulation through tabletop gardening activities planned by the UC Master Gardener leaders. The 90-minute program gave participants the opportunity to touch, move, smell, hear and see the joys of manipulating soil and plants to construct a simple potted creation to adorn their spring celebration table.

UC Master Gardener volunteers knew it would be important to develop activities that were fun and, hopefully, something those in attendance had previously enjoyed. With marigolds, chrysanthemums and mint varieties in hand, participants and caregivers, worked side-by-side and guided by UC Master Gardeners, dug into the bins filled with soil, pots and tools. Each set of participants was given three plants to pot up. As this first activity progressed, UC Master Gardeners could see that participants were being drawn out and interactions around the worktable were increasing. The physical, intellectual, emotional and social benefits of gardening were being experienced and shared by all.

Other sensory-heavy opportunities, all planned and guided by UC Master Gardeners, were included in the program.  Participants were asked to reach into a bin filled with loose soil and wriggler worms to re-familiarize themselves with that most basic part of backyard gardening – working the soil. A variety of plants in one-gallon containers were passed around. Each container was specially marked with an icon that invited the participants to experience the visual beauty, familiar smell, unique feel and, sometimes, sound and subtle taste of each plant. 

Of particular interest was an activity in which everyone was asked to explore a box filled with hand tools, seed packets and other items typically used in backyard gardening. Clearly, old memories were refreshed. A vintage hose nozzle drew the attention of one gentleman. He held it for a while then began making the motions used in hand-watering the yard, moving the nozzle back and forth while mimicking the sound of water rushing forth from the attachment onto a once green and promising flower bed. Tangible signs of success, such as these, were everywhere during the social activity.

Jessica Empeño, MSW, Alzheimer's San Diego's Vice President of Programs and Services was in attendance and praised the work of the UC Master Gardener volunteers. 

“Gardening was such a treat for our families. This activity stimulated all the senses – from the gorgeous colors of the flowers, the smell and taste of the herbs and the chatter and laughter that filled the room. Most importantly, those living with dementia and their care partners were able to socialize and have fun in a safe, judgment-free setting. We are so grateful to the UC Master Gardener Program for donating their time and supplies. We hope to have them back soon!”

The UC Master Gardener Program of San Diego was inspired by its growing understanding of the need for more everyday experiences to address the issues facing members of our community being affected by dementia-related diseases.  Those numbers are increasing at a staggering rate. The National Alzheimer's Association estimates that currently 5.7 million Americans have been diagnosed with Alzheimer's, with nearly two-thirds of those being women, and that number will almost triple by mid-century. In San Diego County, AlzSD offers social activities for individuals with dementia and their caregivers. The “Reminiscence Gardening” project's goal for those individuals is to boost energy levels, build confidence, prolong maintenance of existing skills and perpetuate a sense of purpose and joy through gardening.

Further collaborations between the UC Master Gardener Program of San Diego County and other memory care communities are in the works. UC Master Gardeners want to share their love of gardening and their advanced training from the university for the benefit of those in our community who need it the most. Many of us know first-hand the responsibility of caring for a family member with a dementia-related disease. We know, too, the joys and benefits of being outdoors and sharing time together with people we love.  We want to make a meaningful difference in our community and the Reminiscence Gardening project is a wonderful way to express that.

The worst fire in California history illuminates fire preparation needs

Fire resilient forests have the benefit of offering greater access for recreation. (Photo: Butte County Fire Safe Council)
Four months have passed since the Camp Fire, the worst wildfire in California history, ravaged bucolic communities in the Butte County foothills, including Paradise, Concow, Butte Creek Canyon, Cherokee, Yankee Hill and Magalia. Eighty-five people died, many of them elderly and unable to safely evacuate from an area where a wind-driven fire raced from home to home.

The unspeakable loss of human life and the serious challenges being faced by survivors has dominated the Camp Fire conversation. Now, UC Cooperative Extension is beginning a dialog with many agencies involved to understand how such tragedies can be prevented in the future.

UC Cooperative Extension fire scientists and representatives of many California organizations conduct fire behavior research, study forest treatments – such as prescribed burns, timber harvest and mastication – and share best practices for home and community preparation. In the Butte County area where the Camp Fire took place, cooperating agencies include CalFIRE, the U.S. Forest Service, the Butte County Fire Safe Council, the Yankee Hill Fire Safe Council, Sacramento River Watershed Program, the Sierra Nevada Conservancy, the Bureau of Land Management, and others.

While the Camp Fire was devastating, it could have been far worse. Working together for decades, the partner agencies have improved community safety and resilience.

They have educated the public about defensible space, fire resistant homes, and evacuation plans. They have coordinated fuels treatments along evacuation routes and around the communities. Through their actions, they saved many lives and structures, protected the town's drinking water supply, and in some cases, provided access for hiking in areas that had been overgrown by brush.

“When you drive for miles through blackened, burned trees and then arrive in a thinning project area full of green tree tops, you know that these efforts are worth it, we are having success and we can make a difference together,” said Calli-Jane DeAnda, executive director of the Butte County Fire Safe Council

Because of the Camp Fire tragedy, the partner agencies learned many lessons that can inform future maintenance and treatments to improve fire resilience in Butte County and other wildland areas. Kate Wilkin, the UC Cooperative Extension fire advisor for Sutter, Yuba, Butte, and Nevada counties, is able to point to projects implemented in the Camp Fire zone that saved lives and structures.

For example, one family in Paradise was featured by the news media for their successful advance fire planning, which even included the installation of sprinklers on top of the house.

“When I think about what saves a house, a sprinkler is a cherry on top of the cake,” Wilkin said. “If a house is constructed with a combustible roof and siding, if unprotected vents allow embers to get into the attic, or the landscape is not maintained, a sprinkler isn't going to save the house. The sprinkler's power from the grid or a generator will likely fail. High winds may even prevent the sprinkler's mist from hitting the house.”

Rather, passive resistance to fires through better building design, materials and maintenance greatly reduce structure loss.

“Maintenance is an unsung hero of fire resilience,” Wilkin said. “Individual actions at our homes matter.”

First 5 feet around a structure

State law requires homeowners in wildfire areas to clear 100 feet of defensible space around their structures. Most towns in wildfire-prone areas also have their own defensible space codes. Wilkin said where she lives in Grass Valley, anyone with less than an acre of land must maintain their entire property as defensible space.

This guideline is a start, but there is more that people who live in wildfire-prone areas can do to make their homes resilient to fire. UC Cooperative Extension scientists recommend creating a five-foot buffer immediately surrounding the home almost completely devoid of plants and anything that can burn - including wooden fences, firewood, deck chairs and pillows, brooms and other wooden tools.

This extra precaution is important as embers from a distant wildfire can land on or adjacent to a house and ignite combustible items which in turn ignite the home. It was evident in the Camp Fire that the first five feet around homes was a critical factor in the survivability of structures.

The zone can include noncombustible materials such as rock mulch, stone pavers, cement, bare earth, gravel or sand. Low combustibility materials, such as irrigated and maintained lawn or herbaceous plants less than five inches high, are okay. All leaves, needles or other vegetation that falls in this five-foot zone must be removed during the fire season.

“The non-combustible space adjoining the house may be the difference between losing it and all the contents to a wildfire versus returning to the property with the home unscathed,” Wilkin said.

Community fire resilience

Fire survival measures can also be taken at the community level.

In Paradise, the Butte County Fire Safe Council funded CalFIRE crews to thin a number of areas in the watershed below Paradise Lake in 2013 and 2014. Taking these actions allowed an area for firefighters to start a defense and start putting out the flame front, Wilkin said.

“A CalFIRE chief told residents, ‘You provide the offense, we provide the defense.' Homeowners and communities need to get everything set up for successful firefighting,” she said.

Forest thinning has the added benefit of improving recreational opportunities. Near Magalia Pine Ridge School, an 11-acre mastication project in 2018 funded with $30,000 from the Butte County Fire Safe Council cleared overgrown vegetation around the school. This helped strengthen the area's public assembly location, which was identified on the community's evacuation map, and opened up access to a forest hiking trail that was blocked by tangled brush.

The open space dramatically slowed the raging Camp Fire when it approached the school, which is now one of the only schools open in the Paradise Ridge community.

Forest thinning also protected the drinking water for the town of Paradise. A combination of projects undertaken by U.S. Forest Service, Sierra Pacific Industries and the Butte County Fire Safe Council aligned to allow fire fighters to combat the fire and ensure that the source of drinking water was protected.

Concow wildfire safety zone

In 2013 and 2014, the Butte County Fire Safe Council and Yankee Hill Fire Safe Council created a wildfire public assembly safety zone in Concow. The work was completed by inmate crews. During the Camp Fire, dozens of lives were saved when sheriff deputies, firefighters and citizens were able to shelter in the area.

“Wildfire safety zones are pretty uncommon and we may want to create more in wildfire prone areas,” Wilkin said. “But there is a hitch.”

CalFIRE is reluctant to designate temporary refuges because they don't want people to rely on them in place of evacuation. During a quick-moving firestorm, it could be an area where people can shelter if they cannot get out.

“It's a complex and dangerous puzzle,” Wilkin said. “In Australia, they had a similar idea and some places where people sheltered in a fire caused them to die.”

Wilkin is working with Paradise parks to identify areas ahead of time with enough space to meet new national firefighter standards to protect people's lungs from superheated air.

“Historically, we thought sufficient space was four times as great as the flame heights. If you have a Ponderosa pine that's torching 150 feet high, you would need 800 feet around the people,” Wilkin said. “New research has found that the safety zone calculation must also consider potential wind speed and slope. Significantly more space may be needed.”

UC ANR working with USDA to strengthen extension and farmer incomes in Guatemala

Two UC Agriculture and Natural Resources emeritus specialists, two UC ANR advisors and a UC ANR vice provost spent a week in March working in Guatemala to help implement a USDA-funded (UC Davis-managed) project that is rebuilding the extension system in Guatemala.

With a population of almost 17.5 million and a per capita income ranked 118th in the world, Guatemala is working to improve the livelihoods and incomes of it's rural population, which represents nearly half of the total population. The project is being implemented in Guatemala with the Universidad de San Carlos. Universidad de San Carlos is the biggest and oldest university in Guatemala and which - when established in 1676 - was the fourth university established in the Americas. The 150,000-student university includes a prominent and well-known agricultural school. 

The UC contingent delivered modules on extension and marketing, two of five required for the participants to receive a certificate. Jim Hill, emeritus rice specialist based at UC Davis, is leading the second phase of the project.

The rest of the team for the week were Steve Temple, emeritus agronomy specialist, UC Davis; Jairo Diaz, director, UC Desert Research and Extension Center; Ramiro Lobo, advisor, UC Cooperative Extension, San Diego County; Mark Bell, vice provost, strategic initiatives and statewide programs; and Kate Lincoln, CAES Global Engagement, UC Davis.  Bell led the project when he was part of the UC Davis College of Agricultural and Environmental Sciences.

UC ANR vise provost Mark Bell leads a classroom discussion in Guatemala.

The interactive week-long course worked with 31 participants, mostly from the Guatemalan Ministry of Agriculture extension offices, but also included agriculture teachers. The team shared the essential steps and associated skills required for successful extension. The course used the Spanish acronym ASISTE as a framework (previously developed by Mark Bell, Maria Paz Santibanez and Elana Peach-Fine) as an easy way to remember the key steps. ASISTE stands for audience (audience), soluciónes (solutions), información simple (simple information), transferencia (transfer), and evaluación (evaluation).

As part of the course, participants developed and delivered their own mini-workshops using local issues and context to reinforce workshop discussions. As Guatemala has a large indigenous population with more than 20 languages, one of the participants delivered his talk in Tzutuhil, the main language used for his constituents in Santiago Atitlan, Sonora department.

Soil Health Institute scientist visits UC’s long-term soil health experiment in Five Points

Shannon Cappellazzi, Soil Health Institute is project scientist for the Western U.S.
Shannon Cappellazzi, one of six project scientists involved in an expansive Soil Health Institute (SHI) initiative, visited the UC West Side Research and Extension Center in March to take soil samples from research plots managed for 20 years with soil building practices.

The West Side research plots are one of 120 locations in Canada, the United States and Mexico where the SHI scientists are collecting data to evaluate soil health indicators at a continental scale.

The initiative will identify acceptable soil health measurements and standards, as well as launch a comprehensive evaluation program that relates soil health to productivity, economic and environmental outcomes. Cappellazzi is project scientist for the Western U.S. and coordinates the soil health team's pastures and rangeland research.

“Our project at West Side started in 1999 and is a unique research resource in California because of its dedication to reduced soil disturbance and soil biodiversity in food production systems,” said Jeff Mitchell, UC Cooperative Extension specialist and leader of UC's Conservation Agriculture Systems Innovation.

Since it was established, the research plots have been managed in an annual rotation of cotton, processing tomatoes and more recently sorghum, garbanzo beans and melons, under four different treatments: no-tilled plus cover crops, no-tilled with no cover crops, conventionally tilled with cover crops and conventionally tilled without cover crops.

“There are few long-term study sites in California where this combination of core principles that underlie soil health have been applied for a long time frame like we have here at the West Side REC,” Mitchell said. “These principles include reducing disturbance of the soil, maintaining cover over the soil through the use of residues and cover crops, and accentuating diversity in crops and soil biology.”

UC West Side REC agricultural technician Tracy Waltrip conducting soil hydraulic conductivity determination in the NRI Project field.
Cappellazzi collected samples that will be analyzed for 39 different soil health indicators.  The sampling included real-time measurements in the field during her visit as well as archiving samples that will be sent to four analytical laboratories for an array of tests. 

“Our research project at the West Side REC has enabled scientists to reach many conclusions about soil health in the past. But this very exhaustive sampling by the Soil Health Institute is perhaps the most comprehensive battery of tests that have ever been performed on any study site in the San Joaquin Valley to date,” Mitchell said.

The research initiative is funded with a $9.4 million grant to the Soil Health Institute, the Soil Health Partnership and the Nature Conservancy to improve soil health and support positive economic and environmental outcomes for American farmers and ranchers.

The goal of this project is to support research and education that accelerates adoption and benefits of soil health management systems nationally. Farming practices that improve soil health can increase profitability while protecting natural resources like air and water for communities.

CalLands maps cropland ownership across California

Two UCANR Cooperative Extension specialists have recently launched CalLands, a powerful online tool that can help users understand how land ownership impacts California's croplands.

To build the CalLands' interactive website, Luke Macaulay and Van Butsic — both assistant UC Cooperative Extension specialists based in UC Berkeley's Department of Environmental Science, Policy, and Management — combined satellite-generated maps of land cover created by the U.S. Department of Agriculture with publicly available land ownership records. Next, they anonymized ownership identity and pulled data from all 58 California counties to include parcels of land larger than five acres. The result is a database that features 543,495 privately-owned properties across the state, creating a data-rich map of crops and ownership boundary lines in every county. The interactive map can be filtered by county to display characteristics of land ownership, percentages of private and public ownership, breakdowns by crop-type, and summaries of land-use statistics.

A screenshot of CalLands, and interactive online database that allows stakeholders to understand cropland use and ownership characteristics.

CalLands allows users to explore how crops are distributed within a county or across the state or understand how ownership size impacts how land is used. In a 2017 study on cropland ownership published in California Agriculture, Butsic and Macaulay discovered that the largest five percent of properties account for 50 percent of California cropland. The two created CalLands with the aim of helping a wide variety of stakeholders understand land cover and land use at the county and individual land ownership scale.

“CalLands helps expand people's understanding of the landscape and how farmers across the state are using their land,” Macaulay says.

The website tells the story in visual terms of the location of key crops over time, including water-intensive plants like alfalfa and almonds, and illustrates the locations and acreages of both annual and perennial crops. This information may be useful for those seeking to understand agricultural water use and expansion and change of crops over time. The team hopes that the tool will also help scientists conduct research that is beneficial to many agricultural stakeholders, such as UC Cooperative Extension specialists creating outreach programming, county officials proposing regulations, and resource managers hoping to understand cropland production.

Currently, CalLands features cropland data from 2013-2017, allowing users to toggle between these annual datasets. Macaulay and Butsic plan for future versions of CalLands to include the capability of producing graphs to help users understand how crop planting changes over time as farming shifts and land changes hands. “We look forward to adding more features to CalLands,” Butsic said. “We want to implement changes on the site based on what Californians need.”
