There are deciduous trees here which have given up for the year and are yellowing and dropping leaves. Personally, I think it's a water issue where varieties of trees that require water (like maples) are not getting enough by this time to keep their leaves. We haven't had a decent rain since April or May, which is our usual seasonal pattern.
The redwoods between me and the neighbors are dropping lots of small dead branches which happens every year around this time. Redwoods are having a harder time around here with our weird weather. They love humidity in their branches which the fog usually provides, however the quantity and extent of the fog's intrusion inland this year has been generally low and poor. We've had a lot of overcast mornings (which would often be foggy), but there isn't the blanket of moisture which plants that don't get rain between May and October enjoy and indeed rely on.
Louis, I like the big horn shot. Thanks for sharing.
