Um, I'll bite my tongue, but this is close to where I live and this area of Texas with natural springs and ~30" of rain a year has not been a wasteland for centuries.
Curious as to which oaks are dying? I'm in Bexar County and I'm scavenging chinquapin and bur oak acorns to propagate in case you need some. Pineapple guava, cape gooseberry and goji grow great around here as does pecan.
