"I don't think that map is totally accurate, but as you can see, the Caprock is clearly in the short-grass region".
All the CRP pastures are required to be planted to NATIVE grasses , and up on the Caprock, they are ALL tall grass.Some are over head high.
But....no big deal.
I live in the Tallgrass Prairie and very close to the Cross Timbers and formerly did live
in the Cross Timbers. I've got CRP and have all the grasses you mention in the CRP which was planted around 1999 IIRC. My grass will get over head high in a good year.
I don't know whether they have to be native or not but part of my CRP was specified as being some sort of Fescue. I didn't know of Fescue being native around here so it has always puzzled me.
