“Over an 18-month period starting in 2023, the dense forests of Western Australia [WA] experienced a record-setting drought. Jarrah trees towering 35 metres high died off in patchy brown splotches, turning 400 square kilometres - 3% of the forest - into brittle, fire-prone stands. The event led researchers to wonder whether there was a better way to predict where such die-offs might occur both there and in other forests, a problem that has long been tricky to solve because important factors such as soil depth are hidden underground…
Now, those same researchers have unveiled a surprising new tool for predicting tree mortality: gamma rays [link above.] Resulting from the natural decay of the potassium-40 isotope from granite-rich bedrock, the radiation acts as a proxy for soil depth, which in turn signals how much water a tree can access during drought. The new method could be applied to other highly weathered soils, which cover one-third of Earth’s ice-free land...”

"... PLAIN LANGUAGE SUMMARY: During a record-breaking drought and heat event in 2023–2024, forests in southwestern Australia experienced widespread, patchy die-off. While we know that extreme weather triggers these events, it is often a hidden factor, the thickness of soil and the depth to underlying bedrock, that determines which trees live or die. Trees growing in shallow soil over solid rock are highly vulnerable due to limited water storage. Here, [they] show how to map these hidden zones from the air using gamma rays that are naturally emitted by potassium in the ground. Like southwestern Australia, many parts of the world have highly weathered soils where potassium has been washed out of the upper layers of soil. However, [they] showed that higher potassium areas signal that potassium-rich bedrock is closer to the surface and this is sensitive for tens of meters. By comparing gamma ray maps with ground-based geophysical surveys and satellite data, [they] showed that these potassium hotspots accurately predict where forests are most likely to experience die-off during a drought. These types of soils cover about one-third of the Earth's land, so the method provides a powerful new tool for managers to identify and protect vulnerable forests from future, hotter droughts…”

#NavajoNation Declares #DroughtEmergency as President #BuuNygren Signs Order
by Levi Rickert June 11, 2026
Excerpt: "Commission members advanced the declaration after reviewing worsening #drought conditions across the region and considering recent emergency actions taken by #Arizona and #NewMexico. State officials have pointed to persistent drought, below-average precipitation, elevated #wildfire risks, and growing impacts on #WaterResources and agriculture.
"The commission also reviewed U.S. Drought Monitor data showing that Arizona experienced its hottest and driest January-through-March period on record in 2026, with extreme drought persisting across portions of #Navajo, #Apache, and #Coconino counties.
"To address the crisis, the declaration recommends that the Division of Natural Resources move forward with drought mitigation infrastructure projects, including repairs to #windmills and improvements to livestock #WaterStorage systems.
"The commission also recommended allocating $6,553,730 from the Agricultural Infrastructure Fund to support drought mitigation efforts, including windmill repairs and related water infrastructure improvements.
"In addition, Navajo Nation chapters are encouraged to activate local emergency mitigation plans and coordinate with Administrative Service Centers, the Division of Community Development, the Department of Emergency Management, and other entities to strengthen preparedness and response efforts."

Well, I did NOT finish my #SolarPunk jobs list. But it's on my To Do list... Next week, I'll plan on focusing on #WaterStorage and #Reuse -- #Greywater, #Rainbarrels, #Cisterns, etc., since #Maine is still experiencing a #Drought (despite all the snow), and other places are as well. I know I'll be pestering our Town Manager about getting some rainbarrels and #GreenMachine composters at cost for the local residents.
Boosting some posts from yesterday. I hope you'll join us next #SolarPunkSunday!
