Talking about water

At a recent public meeting held in Contra Costa County by UC Cooperative Extension, a female cattle rancher representing a family that has owned land in the Sacramento-San Joaquin Delta for generations dumped out a grocery bag with dozens of envelopes onto the table in front of her.

“This is the amount of mail I get in one week from agency people," she said, her voice trembling with anger. "They want to come onto my land and look at where they want to put big tubes to carry water down south. My family has been on this property for a long time. It’s my family’s land.”

For this woman and many others, UCCE directors in the five Delta counties opened the flood gates when they invited the public to share their feelings about water. Ten meetings were hosted to give ordinary citizens a chance to speak.

“There is a lot of frustration in the Delta region,” said Carole Paterson, director of UC Cooperative Extension in Solano County. “People felt their voices weren’t being heard.”

Paterson and county directors in Yolo, Sacramento, San Joaquin and Contra Costa counties held community conversations in local libraries and invited the public to have their say. The participants’ thoughts will be synthesized in a written report and some of their comments - videotaped during the sessions - will be part of an audio-visual presentation.

A few common themes emerged from a preliminary review of the 10 conversations, Paterson said.

Frustration. People believe the public policy process is flawed.

Education. People do not understand what is happening to their water. The issues are extremely complex and over the years, layer upon layer of legislation, lawsuits, court decisions and media reports have muddied the water.

Science. People are concerned that science is being manipulated by various stakeholders to support a particular point of view.

The reports on the water conversations will be shared with county boards of supervisors, farm bureaus, legislators, agencies and individuals involved in the state’s water policy.

The Delta faces a host of problems, including invasive species, water degradation due to urban and agricultural runoff, aging infrastructure and the threat of flooding should the sea level rise due to climate change.

“We weren’t looking for solutions,” Paterson said. “We just wanted to give citizens a chance to share their experiences."

Earthworms signal success on innovative tomato farm

If the return of earthworms to farm fields is an indication of success, then Sano Farms is on the right track.

“I haven’t seen earthworms in these fields in years,” said Firebaugh farmer Alan Sano. Sano and his partner, Jesse Sanchez, combine subsurface drip irrigation, winter cover crops and strip tillage to consistently produce a high-yielding crop of processing tomatoes.

In addition to boosting yield, the system they developed for the 4,000-acre farm is cheaper, increases soil organic matter and improves the tilth of their silty clay soil.

The farmers took several trips to the Midwest and consulted with UC Davis Cooperative Extension specialist Jeff Mitchell to learn the improved management techniques they applied on the farm.

After switching from furrow irrigation to drip, Sano and Sanchez began experimenting with cover crops.

"It wasn’t always an easy transition into cover crops," Mitchell said. "It did take some time to learn the best way to manage them."

As the benefits of years of cover cropping accumulated, they saw that they didn’t need to till the entire field to get good soil-seed contact; they only needed to till a strip of soil a few inches wide.

Recently, they shared their innovative farming system with other growers at an open house event sponsored by California's Conservation Tillage and Cropping Systems Workgroup.

Woodpecker-ready siding to cover new conference center

Many people consider acorn woodpeckers' incessant rapping and acorn storage to be a nuisance. But the UC officials who are developing a new conference center at the UC Hopland Research and Extension Center in Mendocino County view the woodpeckers' activities as just another part of the natural system to incorporate into their plans.

The University of California will break ground on the new 5,000-square-foot building this fall. In addition to providing meeting facilities for 200 and display space for a collection of natural and Native American museum pieces, the building itself will be a model of integrated green design, according to center director Bob Timm.

"This won't be a steel box with an air conditioner on the roof," Timm said. "We want a building that fits in the natural landscape, that is in itself teachable. We want a building people will talk about when they come to meetings here."

The architects' inspiration in designing the new conference center was old barns on the research center property that were built when it was still a commercial sheep ranch more than 60 years ago. The barns are riddled with woodpecker holes that the birds use over and over again.

To allow woodpeckers access to the new conference center without compromising the long-term integrity of the building, the facility will be protected with galvanized wire mesh then covered with cedar siding harvested from UC's own Blodgett Forest near Georgetown in the Sierra Nevada.

"This is just one of the ways we will be integrating the building into our rural landscape and making it look like Hopland," Timm said.

Cattle ranching offers notable public benefits

The Sierra Nevada and Coastal Range foothills are replete with wide open spaces - a home for birds and other wildlife, majestic oaks and grazing cattle. The bucolic countryside vistas that come courtesy of California’s ranchers are among the many public benefits of rangeland grazing.

“The public doesn’t always realize what ranchers are doing and how that benefits everyone,” said Bill Tietje, UC Cooperative Extension natural resources specialist based in San Luis Obispo County.  “No one really thinks about it, until it’s gone.”

Many rangeland benefits can be grouped as “ecosystem services.” According to scientists:

  • Rangeland plays a role in the state’s water cycling. Eighty percent of California water flows through rangeland.
  • The diversity of plants and animals is greater on grazed, managed grassland than on unmanaged grassland.
  • Wild raptors overwinter on grasslands managed for beef cattle.
  • Half the habitat for the tiger salamander is grazed stockponds, created by ranchers to provide water for their cattle. The stockpond’s edge of clipped grass and the absence of crowding shrubbery mimic the rare species’ natural habitat – vernal pools.
  • Rangeland provides habitat for insects that are valuable for pollination.
  • Cattle reduce the dry grass that could fuel wildfire.
  • Grazing improves the habitat for the Bay checkerspot butterfly, a threatened California insect.
  • Rangeland sequesters carbon in the soil.

There are threats to the long term viability of cattle ranches in California that put all these benefits at risk:

The sale of the ranch for development is very attractive for a rancher who isn’t making a sufficient profit on the land. Also, the division of a ranch for inheritance purposes can make it difficult to keep a ranch intact and in the business of raising cattle.

UC Berkeley professor of rangeland management and ecology Lynn Huntsinger said public misunderstanding of and a lack of appreciation for ranching is another way the system is threatened.

“Imposing regulations that aren’t needed and not valuing ranchers as stewards can have a demoralizing effect,” Huntsinger said.

Much of the land grazed by ranchers is public and grazing is supported by public and environmental agencies - the U.S. Forest Service, Bureau of Land Management, parks and preserves - because of the many benefits it provides.

Invasive reed arundo is choking state waterways

In the early 1800s, European immigrants introduced the fast-growing giant reed arundo (Arundo donax) into California to use the canes for musical instruments. The plants were also used for erosion control and the reeds used for thatched roofing. However, it has since naturalized and become a serious pest in the state's natural waterways.

Arundo can grow at a rate of four inches per day and can reach heights of 30 feet. It reproduces and spreads when sections of the stem or root break off and float downstream.

Dense stands of arundo displace native riparian species. The plant requires a significant amount of water, reducing fish, wildlife and people. In addition, clumps of arundo and the soil around their roots can break off, causing streambank erosion. The clumps can also create channel obstructions that lead to flooding.

Arundo is highly flammable and can quickly carry fire along waterways. After a fire, arundo quickly grows back from its roots. With other nearby plants burned by fire, arundo can spread even more quickly, leaving no room for native plants to recover.

Californians can help reduce the spread of arundo by taking the following actions:

  • Learn more about arundo, including how to identify it
  • Report sightings to local conservation groups
  • Join local eradication efforts or help to start one
  • If you own land with an arundo infestation, request help and provide access for control efforts
For more information, see the UC Riverside Center for Invasive Species Research website.
