The progression of top dieback in red fir trees, Sierra Nevada Mtns, presumably from overcompetition combined with water/nutrient stress. Can you see how the firs are trying to cope in the two intermediate photos? #forestdecline 🌎🌲🔥🍁🌳🌐🧪

There is a pattern/process I often observe in areas of #ForestDecline that, for whatever reasons, has gone unnoticed by most ecologists. Each of the photos below illustrate this pattern/process at various scales. 🌎🌲🍁🔥🌳🧪🌐🪶🌱🌰

Here are a few more examples showing the same phenomenon. First two are from Southeast Alaska, third is from the Colorado Front Range, fourth is from Whiteface Mountain NY #ForestDecline #WaveDieback 🌎🍁🌳🌐

Very happy to have shared our work on the early detection of Quercus forest decline 🌳 at #EARSeL 2026 today. #Hyperspectral traits, thermal imagery (w/ #CWSI) helped us track early physiological stress before damage becomes visible #RemoteSensing #ForestDecline cc @iascsic.bsky.social @uco.es
