Hi Phillip,
All of the plants you mention provide seeds for wildlife. Deer are especially fond of acorns and a variety of birds eat skunk bush seeds. The leaves are food for caterpillars and oaks are sometimes browsed by deer as well.

Does this grow in sandy soil, clay soil or? Would like to try growing these in Santa Fe

I have seen it in a variety of soils. It should perform well in Santa Fe.

We have many oaks that are all of a sudden turning brown(the leaves) is there a disease or beetle that is causing this? we do not want to lose them if possible.

Thank you

These acorns are edible and don’t have to be treated to remove the bitter constituents. Scrub Jays harvest them to eat during the winter. Possibly due to the lack of bitter constituents, a large percentage of Gambel acorns are usually bug-infested. Scrub Jays pick acorns one at a time and whack them on a tree branch to find out whether they’re bug-infested. Then they either drop the acorn or take it to a staging area where it’s later moved to a more permanent cache. (Because Jays steal from each other, this caching process is elaborate.)

They’re also cached and eaten by Rock Squirrels.

Thanks for this additional natural history on the Gambel.

A number of things could cause oak leaves to turn brown. If they do not leaf out in the spring or the leaves are distorted in some way, take a small sample of stem with leaves to a good local nursery (not a big box store) or your county Extension agent. If there is a Forest Service office nearby that would be another option.
