California's four seasons are fire, flood, mud and drought
Farmers and ranchers are typically the first to feel droughts, a condition that seems to be impacting California on an increasing basis, reported Dustin Klemann on KSBY News on California's Central Coast.
Klemann joined a UC Cooperative Extension drought meeting in Solvang titled “Weather, Grass, and Drought: Planning for Uncertainty.” Ironically, the meeting came at a time when California has been blessed by a series of wet and snowy storms.
“Leave it to a drought workshop to bring the rain,” said UCCE livestock and natural resources advisor Matthew Shapero.
Despite the rain, the National Drought Monitor still considers the Central Coast area to be in "moderate drought."
Shapero told about a local rancher who recently called him to question the status.
“He said ‘I really don't think the drought monitor accurately reflects what I am seeing on the ground.'”
California's drought status is challenging to pin down because of vast precipitation variability. For example, Paso Robles received 2.78 inches of rain all of 2013. In 1941, the town recorded almost 30 inches of precipitation.
UCCE natural resources and watershed advisor Royce Larsen also spoke at he meeting.
“We Californians are constantly accused of not having seasons. We do,” Larsen said. “We have fire, flood, mud, and drought. That's what we live with. And it's getting more and more so every year.”
Central Coast cattle industry suffering losses due to drought
"We see clearly what a bust cycle looks like," said Mark Battany, UC Agriculture and Natural Resources viticulture and soils advisor in SLO County. "Ranchers have no choice but to sell off their cows and rebuild the herd when the rain comes back."
Sahagun reported that ranchers in the area have suffered severe drought for centuries.
"During a drought that ended in 1864, some ranchers drove their herds off cliffs and into the ocean below to stop their suffering," the article said.
The current drought is leaving landowners few options. The county placed a two-year moratorium on new agriculture that depending on the aquifer, so rangeland can't be converted to vineyards at the moment.
"Ranchers are getting hit hard from every direction," said Royce Larsen, UC ANR natural resource watershed advisor in SLO County. "It's a grim and desperate outlook."

Holy S***! Almonds require a ton of bees
Tom Philpott, Mother Jones, May 25, 2015
Growing almonds in California takes about 1.7 million bee hives, drawing a large fraction of the nation's available bee hives. Why don't they stay in California? The state is already home to 500,000 of the nation's 2.7 million hives, said Eric Mussen, UC ANR specialist emeritus based at UC Davis. The almond bloom is great for a few weeks, but in terms of year-round foraging, "California is already at or near its carrying capacity for honeybees," he said.
Farm Beat: Here is how hikers, cattle can coexist
John Holland, Modesto Bee, May 22, 2015
UC ANR released a five-page brochure last month that shows how hikers and other visitors can avoid conflicts with cattle that graze on public land. Cattle fatten up nicely when they can graze calmly – good for the rancher and good for the buyer of the meat down the line, the story said.
Building a better water trough
California’s vast dry rangelands are dotted with water troughs ideal for quenching cattle’s thirst. But in most cases, the troughs’ designs are a torment to wildlife drawn for a drink.
Monterey County rancher George Work observed how traditional water troughs frustrated the wildlife on his family’s 12,000-acre cattle ranch. Small birds couldn’t reach water two or three inches below the top edge. Coyotes, bobcats and cottontails weren’t tall enough to reach over the rim. Work set to making a water trough that would meet the needs of all animals on the range – from cattle, hunting dogs and horses to deer and rabbits.
While raising cattle remains the primary function of the Work Ranch, in order to generate more income from the scenic open space the ranch opens its doors to hunting wild boar, quail and Tule elk. The visitors enjoy seeing a diversity of wildlife.
“One-third of our business comes from wildlife,” Work said.
In 1998, Work drew from decades of first-hand experience to design a better water trough. With a grant from USDA’s Natural Resources Conservation Service, he constructed a prototype. The concrete trough is sunk into the ground under an elderberry tree. Work modified a float like those used in toilet tanks to keep the water within centimeters of the rim.
That first man-made watering hole was an improvement for many species, but it also revealed some problems. Birds needed an escape ramp to climb out of the water should they fall in while drinking; the ramp should be shallow enough to allow the birds to bathe. Larger animals had to be kept from using the trough for a cooling dip. Work found that sloping the sides to a sharp V at the bottom of the trough made it unappealing for a soak.
Years of experimentation and innovation resulted in the development of pre-manufactured concrete water troughs, which are now commercially available. The next challenge is selling the idea to ranchers.
Enter UC Cooperative Extension. On an unrelated visit to the Work Ranch, UC Berkeley wildlife biologist Reg Barrett was impressed by Work’s invention and encouraged UC Cooperative Extension rangeland advisor Royce Larsen and NRCS rangeland conservationist Karl Striby to help spread the word.
Larsen and Stirby are now completing the first step, adding the ground-level water trough specifications to NRCS's published Technical Notes. The publication will provide ranchers and other land owners with the information they need to install the wildlife-friendly troughs.
“If you’re thinking of installing a basic, traditional trough for cattle, it may or may not be the best idea,” Larsen said. “But you’re thinking about supporting both cattle and wildlife, it’s great.”
In the video below, rancher George Work shows the ground-level water trough prototype and the second-generation, pre-manufactured version.

UCCE studies a Dutch invention for regenerating trees and shrubs on oak woodland
The beauty of rolling hills studded with majestic oaks, other trees and shrubbery isn't the only reason to regenerate vegetation. The trees and shrubs create a much more hospitable habitat for a wide assortment of wildlife. Oak woodland vegetation also protects the quality of California water. The majority of the state's water flows through oak woodlands in streams and rivers that support fisheries, farms and cities. Plants and trees anchor the soil, preventing erosion and stream sedimentation.
One of the difficulties ranchers face in regenerating trees is supplying water for seedling establishment. Ranches often stretch for thousands of acres. Hauling water to remote sites or installing irrigation can be prohibitively expensive.
Third-generation San Miguel rancher George Work heard about a new tree establishment invention from Holland – a Groasis Waterboxx. Over the years, Work has collaborated with UC Cooperative Extension on oak planting projects and consulted with UCCE experts about squirrel diseases, ranch animal vaccinations and pasture management. He turned to UCCE natural resources advisor Royce Larsen for his thoughts on the Waterboxx.
“Because of Royce here, our Cooperative Extension agent, he provided a little added incentive when I wanted to try this thing,” Work said. “Royce said, ‘I'll help you.' Well, that was enough to get the job done.”
Work, Larsen and UC Cooperative Extension natural resources specialist Bill Tietje installed 10 Waterboxxes, which cost about $30 each, in a remote area of the 12,000-acre Work Ranch in southern Monterey County. Other plant regeneration methods – including traditional drip irrigation and tree teepees – were also installed for comparison.
The Waterboxx is a round plastic hat box-shaped reservoir that fits around the seedling trunk. When the seedling is planted, the reservoir is filled with about four gallons of water. A rope on the bottom continuously wicks moisture to the plant roots.
The box is covered with an inward-slanting corrugated top that cools during the night and channels condensed dew and fog into the reservoir, keeping it full of water. The Waterboxx provides a protective barrier around the trunk and shades and cools the soil beneath. At the Work Ranch, the plants are also enclosed in bale-wire fence to keep out wildlife poking around for water or hungry for tender green growth.
“The trees are doing surprisingly well," Larsen said. "In just three months, the seedlings have grown more than two feet."
Larsen said he will continue monitoring the project to see if the self-watering system can establish trees. If successful, UC scientists may study the Waterboxx more thoroughly in a replicated research design in Monterey County, San Luis Obispo County and other parts of the state.
