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. #ProtectConglomerateMesa #PublicLands #botany

🚨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. #IndigenousScience #Conservation #MutualAid #botany

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: www.sciencedirect.com/special-issu...
