While looking at axillary buds, I noticed this strange phenomenon in Rhus glabra: The petiole base completely covers & conceals the axillary bud, which is revealed (and can grow) only when the leaf has fallen away. #Anacardiaceae #buds #Botany 🌾🧪🌱

Record (or near record) dry grass/ soil moisture in North/ NW FL.
In the future this will become more common. Not for lack of rain. Instead due to warmer - more thirsty air - stripping the ground of moisture. In decades climate projections show the air could be 50% more thirsty over FL!

The woody biomass of Australia’s tropical rainforests has already switched from carbon sink to carbon source – and the reason is climate change.

Good reporting on widespread Douglas-fir mortality in SW Oregon.
I lived on the edge of the Ashland watershed mentioned in the article ca. 2012-2014.
Even then I was seeing patchy mortality from crowding/drought that I knew would get much worse as temps warmed.
