It has been wonderful to see all the enthusiasm for the #woolydevil in the midst of everything else going on. This is a wonderful write up by @npr.org @jamesdoubek.bsky.social

We are in uncharted territory for resource extraction in the west. If K2's Mojave project is approved it opens the floodgates to countless other destructive projects.

Conglomerate Mesa is one of the most incredible sky islands in the West—rising like a giant cupcake above the desert, frosted with rare plants like the Inyo rock daisy.

Now, Canadian mining company K2 is nearly approved to drill it for gold.

CMH is a priceless and unique collection. It is an herbarium collection curated and maintained entirely by an indigenous botanist Arnold Clifford and his indigenous students.

Donations are needed for a storage shed to protect the collection from weather before it is lost, every dollar helps.

🚨Urgent: Help Save Decades of Work by Navajo Botanists🚨

For decades, Arnold Clifford has built up the Carrizo Mountain Herbarium. Now, this collection is at risk—snowstorms are causing the roof to cave in, putting >30,000 specimens in danger.

Just in time for spring! New research led by @ioana-anghel.bsky.social on the evolutionary origins of desert wildflowers in genus #Linanthus, the desert snow or sand blossoms.

The new species is very rare and we may have only recognized this species on its way out. We were lucky in this case, but there are countless other species of plants and animals on the brink of extinction - even in U.S. National Parks - that have not been studied yet or given a scientific name.

This mysterious plant was first encountered last spring and posted to @inaturalist.bsky.social by NPS volunteer and desert botanist extraordinaire Deb Manley while trekking through the low Chihuahuan desert.

Very excited to introduce the newest genus of wild sunflowers, a tiny desert annual covered in dense wool and heads with just two small ray florets.

A bright spot in a dark week. The International Compositae Alliance (TICA) has just put out the newest volume of the bi-annual publication Capitulum 3(2) and this issue has STYLE. 😎🌼

A really nice effort led by Martí March-Salas (Rey Juan Carlos University-ESCET) with a great group of guest editors.

Here is the link to the editorial we put together to introduce the articles, define some terms, and point out some future directions.

Cliff ecosystems: A critical yet uncharted frontier for research and conservation
Cliffs, all over the world, are often exceptionally rich in endemic, rare and endangered plant species. Historically, cliffs have been among the least…

Cliff ecosystems are rich in bizarre, unique plants and animals but many facts about their ecology, evolution, and conservation remain mysterious.

Now out, open access, is an entire special issue devoted to cliff research in Basic and Applied Ecology:
