Toad invasion no cause for alarm
This time of year, Jimenez said, toads are on the move.
“If they stay together, they will take out all of the food source, so they have to spread out,” he said.
Though the homeowners seemed concerned, Jimenez said they were lucky.
“(Toads) eat a lot of bugs," Jimenez was quoted.
Jimenez said the rush of toads at the Porterville home will not last forever as snakes and birds will begin to snatch them up. If residents wish to reduce their numbers, the toads can be collected and released elsewhere.
Curiously, the story said the family purchased a 5-horsepower garage vacuum to help mitigate the problem.
Register for HFC conference by May 11

Citizen scientists to help track brown widow spiders
Media reports now have residents around the state on the lookout for brown widow spiders, which will help a UC Riverside scientist who is trying to track its rapidly expanding range.
"Wanted dead or alive," announced an article in the Redding Record Searchlight. Reporter Laura Christman tempered the ominous lead with a succinct quote from UC Riverside staff research associate Rick Vetter, "Chill."
"It's nothing to be overly concerned about. I'm more interested from an academic standpoint," Vetter told the reporter.
A native of Africa, brown widows were established in Los Angeles, Orange and San Diego counties as of 2009, and in 2010 made their way to Riverside, San Bernardino, Ventura and Santa Barbara counties. There have been a few finds in areas further north.
Southern California Public Radio KPCC ran an interview with Vetter about brown widows on Sunday. He said the brown widow seems to be displacing black widows - a fact that has benefits and disadvantages.
The brown widow is more likely to play dead than strike out aggressively, however, they tend to congregate in larger numbers and will hang out in places black widows ignore.
"(Brown widows will) be underneath a wrought iron railing or underneath those solar powered lights that you stick in the ground on your walkway. You would never find a black widow in that much of an exposed area," Vetter told the reporter. "It just goes from people having five or six black widows to having 50 to 100 brown widows. And that’s something that you typically would not ignore."
One of Vetter's greatest concerns is a resident's tendency to use more pesticides when confronted with more spiders.
"The spiders are responsible for increasing pesticide load," Vetter said.

Farmers and fisherman unite to restore delta
Family farmers and fishermen, California Indian tribes and grass roots environmentalists are working together to preserve the Sacramento-San Joaquin River Delta and the fish and communities that depend on it for their livelihoods, according to a commentary by Dan Bacher published on Calitics.com.
Calitics is a "progressive online community" that provides individual Californians a platform for discussing state issues and campaigning. Anyone can sign in and contribute to the blog.
Bacher reported on the "Farms & Salmon Summit," held last month in Atwater. During the forum, farmers and fishermen urged political leaders to stop the construction of the peripheral canal, take action to restore salmon, striped bass and other runs, and protect delta and Sacramento Valley agriculture, Bacher wrote. U.S. Representatives in attendence highlighted the importance of keeping the agricultural and fisheries industries healthy.
Ideas and commentary shared at the summit:
- U.S. Rep. John Garamendi said there is a symbiotic relationship between the agricultural community and aquatic interests. "We have to work together to protect the Delta - the solution is not to export more water out of the Delta."
- Rep. Jackier Speier noted that salmon fishing and agriculture are both integral components of the California economy.
- Congressmen Mike Thompson said decisions regarding the Delta and salmon populations should be based on good science. "When science goes out the window, everything goes out the window," Thompson was quoted.
- Vineyard owner Mark Wilson suggested the state start dredging delta river channels. "This would provide material for rebuilding levees, along with restoring the capacity of the delta channels to move water," he was quoted.
- Cathy Hemley from Greene & Hemley Farms in Courtland concluded, "We need to think like a fisherman. We need to think like a farmer. We need to make California sustainable."
Draft delta plan falls short, scientists say
UC Berkeley emeritus professor Henry Vaux Jr. chaired the panel that reviewed the plan, which has been in the works since 2006, has already cost about $150 million and involved hundreds of meetings among state and federal agencies, water districts and environmental and conservation groups.
"Given the time and expenditure of money, people could have reasonably expected to get a plan that was more complete," Vaux was quoted in the story.
AP reporter Gosia Wozniacka wrote that the panel found it unclear whether the main purpose of the plan was simply to build a canal or pipeline, or whether it is a broader plan that would restore and protect the delta ecosystem and provide a stable water supply.
"If you don't know what it is you want to do, it creates a lot of confusion, because the application of science is different depending on what you want to accomplish," Wozniacka quoted Vaux.
Deputy Secretary of the Interior David Hayes said the review provides useful guidance as the plan continues to be developed.
