It is a futile battle, long term. Birds and other critters eat the seeds, and crap them out on your property. It may take 10-20 years, but they'll be back. Still, it does clear out a lot of the mess, and gives the scruboaks and mesquite or whatever else you've got growing some room.
It still doesn't "smell" right when it is gone, though. That cedar smell is just part of that hill country fresh air smell I'm used to.
It is a native plant (well, some varieties at least), and it is going to naturally grow back as soon as you stop killing it off.
Just out of curiosity, what is the motivation for removing cedar, other than to generally thin the undergrowth and for aesthetic reasons? I can understand shooting lanes and such, but the whole property? In my view, it provides food and cover for native animals and birds, so at least some of it would be retained on any property I owned. To each his own I guess.
