“We’ll keep fighting this high-speed roadway because it’s both unlawful and unwise to sacrifice important wildlife habitat on our protected public lands for more urban sprawl.” - Lisa Belenky, senior counsel at the Center for Biological Diversity. biologicaldiversity.org/w/news/press...

When a motorsports outlet sounds the alarm about Utah's attempt to exert control over federal public lands, Gov Cox oughta listen. Just like Mike Lee, Cox's goal here kick the public off our shared land & turn it over to industry pillage. Everyone opposes that. www.rideapart.com/news/784140/...

The Center for Biological Diversity sued the Trump administration today for denying Endangered Species Act protections to the Rio Grande cooter. These freshwater turtles’ fragmented range includes rivers in southern New Mexico, Texas, and Mexico. biologicaldiversity.org/w/news/press...

The Trump administration and the state of Utah today announced an agreement to expand Utah’s control over 8 million acres of national forests with reduced public oversight and weakened environmental reviews. biologicaldiversity.org/w/news/press...

Breaking: Trump's pick to lead the BLM is a walking conflict of interest and an anti-environment extremist who's encouraged vigilantes to seize control of federal public lands. We’re sounding the alarm to Senate leaders. Read the letter, signed by 81 orgs: biologicaldiversity.org/w/news/press...

Just a few things I'd like to say about this @hausfath.bsky.social piece. The first is that every 10th of a degree of heating over 2C raises risks for multiple irreversible catastrophes MORE than every 10th of a degree of heating under 2C. That's why the 2C target exists. It's not random. 🧵

COMMENTARY: Putting Steve Pearce at the helm of BLM would put Arizona’s cherished landscapes at risk of being stripped of protections, ransacked by extractive industries and sold to the highest bidder.

Media advisory: The 9th U.S. Circuit Court of Appeals will hear arguments Wednesday in three related cases that seek to stop the Oak Flat land exchange in Arizona while the lawsuits are pending. More info here: biologicaldiversity.org/w/news/press...

We only have a few days left to stop Trump's extinction plan! The Trump admin. just proposed four new rules that would gut the #ESA and drive imperiled plants and animals closer to #extinction. The new rules aren't just reckless — they're a death sentence. Take action ➡️ https://bit.ly/3LZAGe6

Critical Colorado River update here. Minimum power pool still looms large on Lake Powell’s horizon. Operation of the penstocks and entrainment of bass remains a threat to humpback chub and other ESA-listed fish.

Lawsuit launched to protect critical habitat for Bartram’s stonecrop. Each of this canyon-dwelling beauty’s remaining US populations is tiny and at risk of extirpation from mining water use and other threats. Critical habitat will help secure its future. biologicaldiversity.org/w/news/press...

Judge Patti Saris of the U.S. District Court for the District of Massachusetts vacated Trump’s Jan. 20 executive order blocking wind energy projects and declared it unlawful.

@biologicaldiversity.org is suing to wipe Trump's face off the America the Beautiful National Parks pass. By law, the pass must display the winning photo of a federal #PublicLands picture contest. Instead, Trump plastered his own face on it. Trump's vanity pass is not American, beautiful, or legal

Huge mine trucks and other heavy trucks may soon face strict limits on how many can travel and how fast they can travel on dirt roads in unincorporated Pima County.

My friend Joe has been missing for several days. With each passing day the likelihood that he was just on a long walkabout fades. In 1983 he found a 14K year old mammoth petroglyph, the first found in North America. Here's a short film about him and his sculpture. Brilliant. youtu.be/5t5jU0KzeZs?...

The Center today released video of detonations underway in the Huachuca Mountains -- in critical habitat for endangered jaguar and Mexican spotted owl -- for a double border wall that will block wildlife (but not people) moving between the U.S. and Mexico. Link to PR, video tinyurl.com/y752jz55

The Center for Biological Diversity petitioned the U.S. Fish and Wildlife Service today to protect Allred’s flax under the Endangered Species Act. This rare flowering plant is found only in the Permian Basin in New Mexico and Texas. biologicaldiversity.org/w/news/press...

Breaking The University of Arizona Wild Cat Research and Conservation Center (WCC) has tonight confirmed a brand-new jaguar in the United States, Jaguar #5, never before identified, just days after the Trump administration’s new double border wall construction waivers (see below).

ICYMI: Newly issued waivers allow hundreds of miles of new border infrastructure — including double walls, patrol roads, and industrial lighting — in the last open corridors for jaguars, ocelots and dozens of other animals moving between the U.S. and Mexico. biologicaldiversity.org/w/news/press...

The Center today moved to end a livestock industry lawsuit that'd tried unsuccessfully to stop the Forest Service from removing feral cows from the Gila Wilderness. With the removal complete and cows gone, endangered species habitat along the Gila River is recovering beautifully.

“Looks like a sewer…” Each year the Center surveys ~500 stream miles of endangered species critical habitat on public lands in southwestern riparian areas for livestock grazing damage. We find lots, prompting legal action. As shown here, it can be horrifying. www.propublica.org/article/graz...

Here at #COP30, attendees are lauding AI as an antidote to the climate crisis. While AI can deliver benefits, countries must address AI’s grave costs to our climate, water, & planet. Happy to unpack this w/ @democracynow.org @amygoodman.bsky.social www.democracynow.org/2025/11/19/j...

The Center for Biological Diversity petitioned the U.S. Fish and Wildlife Service today to protect the Mule Mountains population of the Yarrow’s spiny lizard under the Endangered Species Act. biologicaldiversity.org/w/news/press...

The federal magistrate judge on the case had granted the Department of Homeland Security to pause the challenge by the Center for Biological Security, citing the government shutdown.

In beautiful, powerful prose, a resolution from the San Xavier District of the Tohono O’odham Nation celebrates a deep cultural history with jaguar while calling for its protection and reintroduction to historical US range — reaching northward to the Grand Canyon. 👇🏻

This is unprecedented partisan politicization of a public land agency website. I admit chuckling at the sinister irony of “three cheers for volunteers” amidst a shutdown. Lack of agency staff - like for endangered species critical habitat enforcement - risks real to harm our most vulnerable species.

This is like IBM launching a model year 2025 typewriter. www.blm.gov/press-releas...

If you love birds, here's something you can do to protect their habitat. The US Forest Service is proposing to open 45 million acres of national forests to road bulldozing and commercial logging. Here's how to fight back. #birds. www.outdooralliance.org/blog/2025/8/...

Breaking: Trump's DHS waives all enviro laws to wall off premier Texas Wildlife Refuge. There’s a special cruelty in walling off a wildlife refuge created for conservation. All under the guise of a fake emergency, as border crossings are at record lows. biologicaldiversity.org/w/news/press...
