Thanks for the info Wyomiles. During my time at Texas A&M was the height of the cedar hate crimes, and was taught by very intelligent professors of the old school. They noted the benefit to certain wildlife and as well as their usefulness as windbrakes. So i was delighted to see this quote from a link through your provided link (that sounds confussing) as I like for my feelings about a topic to be founded in science...
"Cedars are extremely drought-tolerant, they only use water after significant rainfalls, and they have the ability to almost completely shut down when no water is available (Seiler, 2008). In July of 2008, Dr. Jim Heilman of Texas A&M University released research conclusions that show brushy species use only slightly more water than grassland, and that live oaks use more water than cedar. Further, removing cedar may be unwise because they are an important carbon sink, making them a potential ally in efforts to counter global warming. Heilman said “We’ve seen up to a six-fold increase [in carbon sequestration] with the encroachment of juniper. So, if we remove brush, we might have a marginal savings of water, but we’re losing a heck of a lot of carbon. Overall, Heilman said, the idea of brush removal to save water is a case of where “policy gets ahead of science” (Heilman, 2008)."
However, in Johnson City, TX there is a ranch called the Bamberger Ranch where we took a week long trip to for one of my rangeland classes. This 5,000+ acre ranch that had once been partially used as a quarry, was severly overgrazed and had no water to speak of. The new owner (1970's ish i believe) cleared every cedar tree off that property, and began noticing natural springs returning to the surface immediately. Creeks formed (not just seasonal or weather related, as we visited in June and fresh water was flowing out of the ground in 100 degree drought conditions). Native vegetation thrived, and the rangeland was repaired. This was an immediate result of the removal of the cedars, not a timely return based on quality land management. The was empty quarry pit, now stays near full year round, and was a popular after hours spot during our trip

.
So I believe in taking a scientific approach, but as a former field researcher, i know that parameters for acquiring data are in the eye of the beholder; and that these real world case studies have their place too. I believe the ranch has a website, you should check it out.
I hope that you're not to quick to lable me a "hater"!!! I told you I love cedars, as fence posts (just being ignorant)!!!
