Now: A federal court victory requires federal agencies to provide quantitative, science-based endangered species protections on the Coronado National Forest, where fragile riparian critical habitat has for years been trashed by cattle grazing. Photo: USFWS biologicaldiversity.org/w/news/press...

The Center for Biological Diversity released new footage today of a jaguar roaming the wilds of southern Arizona near a transnational wildlife movement corridor that is rapidly being closed by border wall construction. biologicaldiversity.org/w/news/press...

Now: The Center for Biological Diversity today sued the Bureau of Land Management and Fish and Wildlife Service to end years of unlawful cattle grazing damage to endangered species habitat on the Gila River and in Gila Box Riparian National Conservation Area. biologicaldiversity.org/w/news/press...

The Trump administration today illegally slashed the size of Grand Staircase-Escalante and Bears Ears National Monuments by about 90%. What a travesty. Next, legal action. Press release and my quote linked here: biologicaldiversity.org/w/news/press...

Now: Amid fierce local organizing and good old American civics, an aluminum plant threatening toxic air pollution in Benson, Arizona, and depletion of water from the biologically diverse San Pedro River was scrapped today. Robin Silver Photo biologicaldiversity.org/w/news/press...

Now: The Center for Biological Diversity today expanded our Big Bend litigation to challenge the Department of Homeland Security’s action on Tuesday waiving dozens of environmental laws to build border barriers and roads through Big Bend National Park. biologicaldiversity.org/w/news/press...

Now The Center for Biological Diversity sued two Interior Dept. agencies today for failing to protect endangered species and their streamside habitat from unauthorized cattle and grazing damage in southern Arizona’s Las Cienegas National Conservation Area. biologicaldiversity.org/w/news/press...

An appeals court today rejected cattle growers' challenge to the Forest Service's removal of feral cattle from the Gila Wilderness. The Center had urged the dismissal. Three years cow-free, the Gila River's endangered species habitat is now recovering. biologicaldiversity.org/w/news/press...

The Center for Biological Diversity sued the Trump administration today for failing to finalize Endangered Species Act protections for the Quitobaquito tryonia, a tiny springsnail found only in Quitobaquito Springs in Organ Pipe Cactus National Monument. biologicaldiversity.org/w/news/press...

Now: The @biologicaldiversity.org today filed a notice of intent to sue federal agencies to end unauthorized livestock grazing damage to endangered species habitat on Arizona's upper Verde River, the second such suit against the agencies in recent years. biologicaldiversity.org/w/news/press...

Now: The Center for Biological Diversity, San Carlos Apache Tribe and Lower San Pedro Watershed Alliance just notified federal agencies of our intent to sue over Endangered Species Act violations at the Copper Creek Exploration Project near Mammoth, AZ. biologicaldiversity.org/w/news/press...

Colorado River decline is increasingly dangerous for Grand Canyon's humpback chub. Record low pool elevations at Powell mean far more bass passing through the dam, and hydropower is urging BOR to end cool mix-flows that suppress bass recruitment downstream. biologicaldiversity.org/w/news/press...

BREAKING — More than 130 conservation groups, outfitters and rural Texas businesses urged Congress today to block federal funding for border wall construction in Big Bend National Park and Big Bend Ranch State Park. biologicaldiversity.org/w/news/press...

Reclamation’s power pool projection for Dec at Glen Canyon Dam sets up for more Upper Basin drought releases and less from Powell this year. But it’s also ominous for the Grand Canyon’s humpback chub; a low lake and warm water threaten to pull a dangerous new pulse of invasive bass through the dam.

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...

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

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...

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.

The Center for Biological Diversity and San Pedro 100 sued Arizona Department of Water Resources Director Tom Buschatzke today for failing to review adequate water supply designations for 55 Fort Huachuca/Sierra Vista-area subdivisions. biologicaldiversity.org/w/news/press...

7 June. Red Butte. Defend Baaj Nwaavjo.

Here, a bad shot of a Cape May Warbler yesterday (25 May 25) along the San Juan River in Bears Ears National Monument — very unusual and exciting to see this bird so far outside its usual range.

We’ll see. Mildly refreshing — like stepping out of an outhouse — to see Zinke maybe trying to remove something other than national monuments, methane waste prevention, or NEPA for oil gas leasing.

Looking forward to upcoming field time in the Chiricahuas. Spring birds! An elegant trogon photo from most recent visit.

Big beautiful rally for #publiclands today at the Arizona Capitol! Arizonans unified for keeping public lands public! #keepitpublic #protectpubliclands #protectnationalmonuments

During Trump 1, “expedited environmental approvals” usually yielded arbitrary and illegal decisions that were never implemented. So will go Trump 2.

Happy Thanksgiving

Hi folks, I’m Taylor — new here, like many — eager to connect. I’m the Southwest director at @centerforbiodiv.bsky.social, working to safeguard biodiversity, endangered species, and public lands of Arizona, New Mexico, and the Colorado Plateau.

As I assess migration to this platform, here are some recent autumnal Mogollon scenes.
