I noticed in R.Rooster's essay (with the wonderful pictures) of a few days ago, that he mentioned the Mesquite tree. I know that in some places mesquite is considered invasive but in my area of TX, I think the opposite is true. Over the years I have seen a steady, relentless, elimination of the trees and plants of this countryside. We have eradicated most of our native plants and have replaced them with tightly packed neighborhoods, apartment complexes, strip malls, and highways. We have choked out the native habitats. The wide-open spaces and vistas that were prevalent here, are rapidly disappearing.
