First national analysis finds America’s butterflies are disappearing at ‘catastrophic’ rate

Seth Borenstein, ASSOCIATED PRESS

America’s butterflies are disappearing because of insecticides, climate change and habitat loss, with the number of the winged beauties down 22% since 2000, a new study finds.

The first countrywide systematic analysis of butterfly abundance found that the number of butterflies in the Lower 48 states has been falling on average 1.3% a year since the turn of the century, with 114 species showing significant declines and only nine increasing, according to a study in Thursday’s journal Science.

“Butterflies have been declining the last 20 years,” said study co-author Nick Haddad, an entomologist at Michigan State University. “And we don’t see any sign that that’s going to end.”

A team of scientists combined 76,957 surveys from 35 monitoring programs and blended them for an apples-to-apples comparison and ended up counting 12.6 million butterflies over the decades. Last month an annual survey that looked just at monarch butterflies, which federal officials plan to put on the threatened species list, counted a nearly all-time low of fewer than 10,000, down from 1.2 million in 1997.

Many of the species in decline fell by 40% or more.

Historic pact reached on future Eel River water flows into Russian River

A historic agreement has been reached to manage water flow from the Eel River to the Russian River.
The deal establishes limits on diversions, focusing on fish protection.
Water rights are transferred to the Round Valley Tribes, supporting river restoration efforts.

Officials from three counties and the Round Valley Indian Tribes have reached a historic agreement that paves the way for continued diversions from the Eel River to bolster flows in the Russian River.

The agreement represents a critical development for anyone whose water comes from the Russian River.

The complex accord resulted from years of negotiations to preserve supplemental flows in the Russian River, the water lifeline for residents, ranchers and wildlife in Sonoma and Mendocino counties. The agreement also supports the restoration and fish recovery in the Eel River, which was crucial to securing support from environmental interests, tribes and Humboldt County residents.

It is, at last, the “two-basin solution” envisioned by regional stakeholders in 2019 and even earlier, when Pacific Gas & Electric first raised questions about whether to continue operating the small, aging hydroelectric plant in Potter Valley through which Eel River flows have been redirected.

The utility is now on track to decommission the plant, tear down Scott Dam, which impounds Lake Pillsbury in Lake County, and Cape Horn Dam 12 miles downstream, where Eel River water has long been diverted.

Rep. Jared Huffman secures $15 million for Eel River Dam removal and Russian River diversion plan

UKIAH DAILY JOURNAL

Rep. Jared Huffman, D-San Rafael, recently announced that the U.S. Bureau of Reclamation has awarded Round Valley Indian Tribes and the Sonoma County Water Agency $15 million toward implementing the Two-Basin Solution for water diversions from the Eel River to the Russian River.

In a press release, Huffman explains that “the funds through the Inflation Reduction Act will fund a major Eel River estuary project supported by the tribes, and put a down payment on construction of a new wintertime diversion to the Russian River following the removal of two salmon-blocking dams on the Eel.”

“This funding shows what can be accomplished thanks to the strong partnerships in the Eel and Russian river basins. We’ve now reached a significant milestone in restoring salmon and other aquatic life in the Eel River while protecting a key water supply for communities in Mendocino, Sonoma, and Marin counties,” Huffman is quoted as saying in the release.

Explaining that “the Pacific Gas and Electric Co. plans to remove Scott and Van Arsdale dams that no longer produce electricity but prevent salmon from reaching 200 miles of spawning habitat, Huffman also notes that “Round Valley Indians Tribes and Sonoma Water worked together on the application and are also working with Mendocino Inland Water and Power Commission on a plan that will benefit both basins.”

Deal announced to end most ranching in Point Reyes National Seashore

John Beck, NORTH BAY BUSINESS JOURNAL

Nearly three years after environmental groups sued the National Park Service, most of the ranches in Point Reyes National Seashore have agreed to shut down and stop farming as part of a landmark settlement, the park announced late Wednesday.

The park will phase out farming at 12 out of 14 ranches operating within the seashore over a period of 15 months, said park spokesperson Melanie Gunn. Two other ranches are seeking to continue under new long-term lease extensions, she said.

The deal was brokered by The Nature Conservancy in closed-door talks involving the ranches, the environmental groups and the park service.

Spawning Chinook salmon return to Sonoma Creek in wake of recent storms

Martin Espinoza, PRESS DEMOCRAT

Copious early rainfall and efforts aimed at restoring local salmon and steelhead trout habitat have made such scenes possible, local ecologists say.

A female Chinook salmon swam steadily against the current in a shallow section of Sonoma Creek as several male fish splashed about behind her, jockeying for position, waiting for her to lay her eggs.

Just a few yards downstream on Wednesday, near the bank of the creek, another female rolled onto her side and smacked the gravel and rocks with her tail, doing her part to dig a “redd” or nest as the current flushed away silt and sediment that can be harmful to egg development.

This spawning scene for Chinook, or king salmon, in the headwaters of Sonoma Creek within Sugarloaf Ridge State Park is an uncommon sight for most local residents.

But since late November, hundreds of Chinook have traveled up the watershed from San Pablo Bay and been spotted in numerous tributaries that drain Sonoma Valley and its surrounding elevations.

Heavy rains in November and December have created ideal stream flows that have allowed spawning salmon to make their way into the region’s headwaters, said Steven Lee, research program manager of the Sonoma Ecology Center, which monitors the health of the Sonoma Creek watershed.

Sonoma County must suspend non-emergency well drilling under court order

Emma Murphy, PRESS DEMOCRAT

It is the latest development in a lengthy legal fight between the county and environmental groups who contend heavy groundwater pumping is doing harm to streams and aquatic wildlife. The county, those groups say, must conduct deeper study of those impacts and craft stronger regulations to safeguard natural resources that belong to the public.

Sonoma County has once again suspended permitting for non-emergency well drilling, this time under the order of a Sonoma County judge.

The order follows an August ruling in which Superior Court Judge Bradford DeMeo determined the county violated state environmental law in its attempt to draft a controversial ordinance governing wells and groundwater use.

In light of that finding, the county must halt non-emergency well-permitting until it can complete an environmental review of the ordinance in alignment with state law, the court ordered.

National Park Service agrees to halt removal of disputed Point Reyes seashore fence, but Tomales Point elk are already roaming freely

John Beck, PRESS DEMOCRAT

The National Park Service agreed in court Friday to stop taking down the fence in Point Reyes National Seashore that separates several hundred tule elk from adjacent dairy farms and ranches, bowing for now to a last-minute legal challenge from ranchers.

It’s the latest twist in the ongoing saga of an 8-foot-high fence that environmentalists are calling the “ungulate Berlin Wall” and ranchers see as the next step in an ongoing push to oust them from the park.

“It’s a win for what it’s worth,” seashore rancher Kevin Lunny said of Friday’s court proceeding.

In the hearing in U.S. District Court Judge Jacqueline Scott Corley’s San Francisco courtroom, attorneys for the federal government agreed to halt fence removal that started Tuesday morning, a day after park officials issued a decision to remove the nearly 50-year-old fence, culminating several years of public comment and environmental assessment.

A handful of crab boats experimented with a new gear. Can it keep whales from being entangled?

Mary Callahan, PRESS DEMOCRAT

A trial of innovative crab fishing gear designed to reduce whale entanglements is being hailed as a resounding success that should advance widespread use of the new technology off the California coast sometime soon.

But the reception to the trial and reports of its success have opened a window into profound conflict within the Dungeness crab fleet over the future of the industry, the squeeze of government regulations, and mistrust of the technology and those who promote it.

Battered economically by shortened crab seasons for six years and the total closure of king salmon seasons for two years running — many fish for both — commercial crabbers are at once desperate for more opportunities to fish and eager to reclaim some control over their livelihoods.

They have largely resisted the idea of so-called pop-up gear, citing the expense of converting their equipment, doubts about its reliability and concerns that failures and unintended consequences could actually lead to more whale entanglements.

Nineteen commercial crabbing boats participated in the largest experiment to date, fishing with “ropeless” gear from April 9 through June 30, when most of the fleet was shut out of the crabbing grounds because of concerns about ensnaring marine animals.

Watching native fishes vanish

Andrew Rypel & Peter Moyle, CALIFORNIA WATER BLOG

It’s an odd, disturbing feeling – watching populations of native fish species collapse and then disappear. Sometimes it happens quickly, other times it’s a series of slowstep change events. The end result is the same though – smaller populations, extinctions, less biodiversity. We put up a little fight, and occasionally have moderate success. But by and large, the overall trend is down, the pace of change quickening, and it is relentless. We’ve watched it over our careers, and maybe some of you have too. Either as biologists or water professionals, or perhaps as long-time readers of this blog. This summer has been no different. It has been an avalanche of stories, all with variations on this theme. Here, we provide a synopsis of some recent events, along with wider thoughts on what watching this happen means.

When we lose species, it speaks volumes about our inability to prevent ecosystem decline, and to constantly borrow from nature without repayment (Rypel 2023). The pattern is especially sobering with charismatic species such as Chinook salmon, which receive large amounts of conservation funding and attention. This is a clear and unambiguous signal that cannot be ignored. But what should we do about it? A good start might be the development and implementation of a comprehensive fish management plan for California. We provided some scaffolding for what such a plan might look like in a previous blog. The 30×30 conservation goal of the Resources Agency can boldly protect many declining fishes if fully implemented. This initiative seeks to directly protect entire watersheds, including where many declining fish occur.

A look at the $10B climate bond (Prop. 4) California voters will decide on in November

Manola Secaira, CAPRADIO

In November, California voters will decide whether to approve of a bond that would fund state climate initiatives.

Proposition 4 on Ballotpedia

Legislators announced the $10 billion bond will appear on the November ballot as Proposition 4 earlier this month. Dozens of environmental groups advocated for it, especially in light of state budget cuts made earlier in the year that impacted climate programs.

Many advocates are optimistic voters will approve of the bond, citing a PPIC survey published earlier this month that found 59% of California voters would likely vote “yes.”

Assembly member Lori Wilson was one of the legislators who introduced the measure. Before it came together, she said she’d been working to introduce a bond measure that would focus on agriculture. But she and other legislators eventually decided they’d see a better chance of success if they pooled their bond proposals.

“Once we started to see the cost of inflation, just the impact that the voters were feeling, we knew there really wasn’t an appetite for multiple bonds on the ballot and there would have to be consolidation,” Wilson said.

The bond would be paid off by California’s general fund, which is supported, for the most part, by tax revenue. The state’s legislative analyst’s office says the estimated cost to repay the bond would be $400 million a year over the course of 40 years.

Supporters say the bond would provide much-needed funds to accomplish California’s ambitious environmental goals, like its commitment to conserving 6 million acres of land by 2030.
