Center for Biological Diversity News Release

WASHINGTON— An assessment released today by the Environmental Protection Agency found that three popular neonicotinoid insecticides are likely to jeopardize the continued existence of more than 200 plants and animals protected under the Endangered Species Act. This includes 25 insect species and more than 160 plants dependent on insect pollination.

The new finding on clothianidin, imidacloprid and thiamethoxam comes one year after the agency completed biological evaluations on the pesticides. Those assessments found that the vast majority of endangered species — 1,225 (67% of all endangered species) for clothianidin, 1,445 (79%) for imidacloprid, and 1,396 (77%) for thiamethoxam — were likely harmed by these three insecticides.

Today’s finding focuses on which species are likely to be driven extinct by these three insecticides. These imperiled species include Attwater’s greater prairie-chicken, rusty patched bumblebee, Karner blue butterfly, American burying beetle, Western prairie fringed orchid, vernal pool fairy shrimp and the spring pygmy sunfish.

NPR  reported on why we need to keep a distance from wild animals

Yellowstone National Park rangers euthanized a newborn bison calf after a visitor touched the animal, trying to help it catch up with its herd, the National Park Service said on Tuesday.

The herd had been crossing the Lamar River on Saturday evening when the calf got separated from its mother on the river bank, according to a press release from the agency. A man observing the scene approached the animal with apparent rescue intentions.

“As the calf struggled, the man pushed the calf up from the river and onto the roadway,” NPS said. “Visitors later observed the calf walk up to and follow cars and people.”

Astronomers Detect a Star Devouring a Planet

NASA reports

A star nearing the end of its life swelled up and absorbed a Jupiter-size planet.

In about 5 billion years, our Sun will go through a similar end-of-life transition.A new study published online Wednesday, May 3, in the journal Nature documents the first observation of an aging star swallowing a planet. After running out of fuel in its core, the star began to grow in size, shrinking the gap with its neighboring planet, eventually consuming it entirely. In about 5 billion years, our Sun will go through a similar aging process, possibly reaching 100 times its current diameter and becoming what’s known as a red giant. During that growth spurt, it will absorb Mercury, Venus, and possibly Earth.

Yosemite Closures & Water Conditions

When unusually warm weather meets several feet of dense Sierra Nevada snow, things get interesting. All that water has to go somewhere! Quite a bit is flowing through Yosemite Valley right now, tumbling spectacularly over cliffs and cutting through canyons, pouring into the Merced River and overflowing its banks, blissfully unconcerned with human inventions like roads and campgrounds.
🚩 Minor flooding continues in Yosemite Valley, with water levels forecast to peak over the next few nights. Forecasts show cooler weather and decreased flooding starting mid-week, but we expect additional flooding off and on until early July.
🚩 Housekeeping Camp, Lower Pines Campground, and North Pines Campground remain closed at least through Tuesday night. No additional closures are planned at this time, though this could change if the river rises more than forecast.
🚩 Visitors may encounter water on roads, especially in the morning and evening.
🚩 Admire rivers, creeks, and waterfalls from a safe distance. Flowing water is surprisingly swift, cold, and dangerous, even if it appears calm from the surface. Stay back from flowing water, and keep off of slick rocks along waterways.
🚩 Do not attempt to cross bridges with water flowing over them.
🚩 We shouldn’t have to say it, but do not try to wade, swim, or float on any rivers or creeks. Yosemite’s waters are completely closed to rafting and other recreation. Rivers are icy cold, incredibly powerful, and extremely hazardous.

Science Alert  reports 

Scientists are alarmed as sea surface temperatures stubbornly maintain record-breaking highs for more than a month, pushing the state of Earth’s oceans into uncharted territory.

Starting in mid-March, data from the US National Oceanic and Atmospheric Administration (NOAA) leaps dramatically from earlier recordings, following lows of both Arctic and Antarctic sea ice this year.

Science  reports

Scientists long thought only insects and birds served as pollinators, but research has revealed that some reptiles and mammals are more than up to the task. Now, scientists must consider whether amphibians are also capable of getting the job done. It’s likely that the nectar-loving frogs, also known as Izecksohn’s Brazilian tree frogs, are transferring pollen as they move from flower to flower, the authors say. But more research is needed, they add, to confirm that frogs have joined the planet’s pantheon of pollinators.

Wild horses are turning up dead at Mono Lake after snow melts

The L.A.Times reports

Several wild horse carcasses have been discovered this spring on the southwestern shores of Mono Lake, after California endured a cold and snowy winter.

As multiple feet of snow finally melted around one of Mono County’s greatest attractions, U.S. Forest Service officials and volunteers found remnants of a large presence of wild horses — ones that typically range much farther east — that wintered around Mono Lake and left behind massive amounts of manure, ecological damage and in some cases, decaying skeletons.

Sonora Pass Update

On State Route 108 (Sonora Pass), maintenance crews have reached Upper Sardine Meadow.
Here, the snow is between five to seven feet deep. That might not sound like a lot, but as they draw closer to the Mono/Tuolumne County Line, they’re encountering heavy, moisture-rich snow that is dense and tightly packed.
Crews are still utilizing multiple snowblowers and a snowcat to clear the roads. Maintenance crews on the ground anticipate they’ll reach the deepest snow on the highway within the next week.

The Guardian writes about the threat of superbloom tourism to California’s wild areas

The spectacle that washes hillsides in color draws thousands each year, but raises generations-old concerns about protecting wild spaces.

But the crowds also can make their own paths through sensitive areas, causing damage and threatening the future of the phenomenon. While debate over how to balance appreciating the superbloom without overwhelming it has intensified in recent years, it reflects concerns about society’s creep into wild places that date back more than a century, particularly during periods o

Yosemite Tioga Road Snow Clearing Progress

Snow is flying on Tioga Road this spring! After an unprecedented winter, much of Yosemite’s high country is still covered in several feet of snow, and the park’s dedicated road crew really has their work cut out for them.
Each spring, crews work to clear 45.5 miles of road between Crane Flat and the entrance station at Tioga Pass. As of Saturday, May 13, plows have cleared the first 11 miles of road, cutting a deep corridor through the snow.

The illusive giant armadillo

The Guardian reports on the illusive giant armadillo

Weighing up to 50kg and growing up to 1.5 metres in length, the giant armadillo (Priodontes maximus) is bigger than most large dogs, with a 15cm sickle claw used to plunder rock-hard termite mounds. Yet it was one of the least understood – and least recorded – animals. With a very low demographic density and shy night-time behaviour, the giant armadillo was mostly a ghost of South America – until Desbiez set to work.

Yosemite Closure Updates

Due to a forecast of flooding, Lower and North Pines Campgrounds and Housekeeping Camp will close on Monday morning, May 15. Additional closures are possible. We will provide an update by Monday evening, May 15.
Unlike the last month’s forecast of flooding, the extended forecast calls for warm weather indefinitely. As of May 1, the park had more than double the average amount of snow for this time of year. The combination of extended hot weather and abundant snow means the Merced River may remain above flood stage for some time.
Yosemite Valley, Wawona, and the Mariposa Grove are accessible by entering Yosemite via Highways 41 and 140. (Reaching the Mariposa Grove requires a four-mile round-trip hike with 500 feet of elevation change.) Hetch Hetchy and Hodgdon Meadow (but not other areas of Yosemite) are accessible via Highway 120 from the west. Tioga, Glacier Point, and Mariposa Grove Roads are closed.
