Focus: Do Dead or Dying Trees Raise Wildfire Risk?

As a record number of trees stand dead or dying in California’s forests due to drought and beetle infestations, concerns are mounting that the die-off is creating an abundance of fuel likely to trigger wildfires that could threaten homes and lives.

However, an emerging body of science finds little evidence to support these fears. Researchers studying wildfires across the western United States during the past decade have increasingly concluded that forests ravaged by bark beetles and other insects aren’t more likely to burn than healthy expanses of forest.

County Saw Major Water Savings in May

Residents and businesses statewide, including those in San Diego County, continued to save water aggressively as officials began moving forward with loosening emergency conservation standards. Regulators on Wednesday released their analysis of water consumption in May, the most recent month for verified data. Their reports are issued monthly as part of a program created in response to California’s historic drought, which is deep into its fifth straight year. Water use in May was 28.2 percent lower than during the same month in 2013 — Gov. Jerry Brown’s benchmark time period for his conservation mandate, which took effect in June of last year.

North County Report: Agencies Consider Rolling Back Water Mandates

As water restrictions shift to local water agencies, a few North County communities are moving to ease limitations after winter storms. In Del Mar, city staff recommended downgrading the drought level, which would have allowed power-washing the sidewalks, and turning on the showers at the beach, The Coast News reports. Not all members of the City Council were on board, though. “I think it’s a mistake to relax our drought restrictions — a big mistake — because the drought’s not over,” Councilman Don Mosier said.

Facing Historically Low Levels, Lake Mead Officials Are Fending Off a Water War. Here’s How

This may be what the start of a water war looks like.

Drought is draining the West’s largest reservoir, Lake Mead, to historic low levels. Forecasts say climate change will make things worse. Headlines warn of water shortages and cutbacks. Members of Congress are moving to protect their states’ supplies.

Yet if war is really imminent, why is one of the region’s most experienced water managers doing the same thing he has done for years: tinkering?

“I like to describe this as another incremental step,” said Tom Buschatzke, director of the Arizona Department of Water Resources.

Long Beach to study health of trees, create maintenance plan for urban forest

City officials hope to better understand the health of Long Beach’s urban forest, which contains some 92,000 street trees throughout the city.

As cities across Southern California have grappled with a historic drought and worked to comply with state-mandated watering restrictions, trees and park systems have suffered, including those in Long Beach.

A handful of City Council members, led by 5th District Councilwoman Stacy Mungo, asked the council to support having the Public Works Department study the condition of the city’s street trees – and based on that assessment, develop a life-cycle management plan.

Are California Redwood Trees the Answer to Global Warming?

California’s ancient redwood forests aren’t just majestic and among the oldest living things on Earth — a new study finds they are a particularly potent weapon against global warming.

The towering trees remove and store more carbon from the atmosphere per acre than any other forests on the planet, including tropical rain forests, researchers found in a discovery that could influence everything from logging rules to how parks are preserved as the state grapples with climate change.

Downtown L.A.’s Five-Year Rain Total is Lowest Ever Recorded

Los Angeles has chalked up yet another dreary milestone in its growing almanac of drought.

On Wednesday, experts at the National Weather Service confirmed that the last five years have been the driest ever documented in downtown L.A. since official record keeping began almost 140 years ago. Having missed out on most of El Niño’s bountiful rains this winter, the Southland experienced yet another dreadfully below-average year of precipitation between July 1 and June 30. As a result, downtown Los Angeles recorded an average of just 7.75 inches of rain every year since July 2011, according to NWS meteorologist Scott Sukup.

 

Del Mar Lowers Drought Response Level

Council members opted to follow state and local recommendations and agreed to reduce the drought response to Level 1. Last month, when staff suggested the change based on increased water supplies due to winter storms and Carlsbad’s desalination plant going online, Councilman Don Mosier called the move “premature” and a “big mistake because…two-thirds of the state is still in a drought.” “You’re undoing a good program,” Mosier said at last month’s meeting in an effort to convince his colleagues to leave the response level unchanged. “This community’s adapted to using less water, and I think we should continue to do that.”

 

Desalination Plants Get a Reboot to Fight Water Shortages

On an overcast day in May, construction is in full swing on the Charles E. Meyer Desalination Facility in this affluent enclave on the Central California coast. Several workers fine-tune rebar in foundations for processing units, while two others deploy a large spinning plate to melt the edges of an ocean intake pipe so it can be attached to another pipe. In response to California’s epic drought, the Santa Barbara City Council voted last year to reactivate a desalination plant built in 1992 to fight an earlier drought. It operated for only six weeks before being shuttered.

San Diego Water Authority Is Pretending the Drought Is Over; It’s Not

Without mandatory conservation, San Diego is positioning itself to fall back into the same short-sighted planning that built the state’s drought inadequacies in the first place. For decades, the San Diego region inched closer and closer to a drought crisis, pumping more water for more lawns from the ever-dwindling supplies in the Colorado River Basin and the Bay Delta. We were addicted, concerned with getting more water today, not the drought tomorrow. Then we hit rock bottom. In 2015, after we failed to respond to voluntary conservation calls to action, Gov. Jerry Brown declared a state of emergency.
