What an interesting thread, am now reading T. Fehrenbach's Lone Star book now.

The King Ranch by Tom Lea was an incredible read, albeit a long one.
Observing and Evaluating Whitetails by Dave Richards and Al Brothers
If you arrowhead hunt, "A Field Guide to Stone Artifacts of Texas Indians"
Devil at my Heels by Louis Zamperini was a great read, but not necessarily on the topics you provided.
Dolph Briscoe: My Life in Texas Ranching and Politics

any Dobie book or McMurtry book

Also...I have a publishing company: www.HaveYouThought.com that has books that are either written by, or about Native American Indians and Indigenous Elders, worldwide. I'd be happy to ship you some of them for free, if they seem interesting. We also have some audio CDs on the site as well.

Not being from TX, I don't know any books, but hopefully this will help you and maybe others who are not aware of this website, but if you are looking for a good deal on a certain book go to bookfinder.com . It will search multiple sites and show you the cheapest place to find a book. I have found a lot of books that I thought I would have to pay out the wazoo to get and ended up getting them rather cheaply. BTW-sounds like you are headed down the right path in your studies.

Nice link, sir.

Dr James Kroll is a great authority, out of Stephen F. Austin. Patterning Whitetails is a great reference.

Just finished Adios to the Brushlands, thanks, deerfeeder! I bought all three of Longoria's books. "Adios" really hit home as the Author and I are very near in age, and I too have witnessed the loss he describes in South Texas first hand.

A Practical Guide to Edible & Useful Plants
by Delena Tull

This is the best book I've seen on edible plants, harmful plants, and plants useful for crafts & dyes.

I am mentioned in Adios to the Brushland. Me and Longoria are good buds. We text, talk and email quite often. Saw him about a month ago. We had coffee down in San Isidro.

The man knows his stuff. He has a blog. http://woodsroamer.blogspot.mx/

Highly recommend:

For just great hunting and fishing stories, Bob Brister, Golden Crescent. Long out of print, a bit expensive, but worth it. Also includes wonderful art by Jack Cowan, one of the artists that truly defined art of South Texas hunting and fishing. Truly outstanding quality writing and a great gift to yourself.

If you want genuine South Texas stories and descriptions of Texas geography and wildlife read Early Settlers and Indian Fighters of Southwest Texas by Andrew Jackson Sowell. He personally interviewed many original setters in Texas and recorded their stories first hand of hunting, land, animals, Indians, etc. Some of the previous books mentioned used Sowell as a reference. I also kept seeing Life of Robert Hall used as a reference in many books when referring to hunting stories. He was a guide and hunter with great stories of hunting bears, deer, lions, and buffalo (American Bison) in South Texas.

Lots of excellent suggestions above.

For humor - The Deer Pasture, by Rick Bass. He's written other books that are good, but this was one of his earliest, maybe his first, before he got all holier-than-thou bowhunter, you should only hunt as I do; he moved to MT and lives in the Yaak valley. His short story collections, many about living in Houston suburbia, are a riot.

Loved The Deer Pasture.
Slogged my way through a recent book of his short stories. Wished I had that time back. Just not my cup of tea I guess - seemed if he was just riffing by jumping from one absurd scenario to another with no direction I could discern.
