When just 23 were left in Yellowstone National Park. a Texan revived the herd. To be honest, Texas had considerable liability in driving the poor bison to near extinction in the first place. However, once people finally realized the range just wouldn't be as happy a home if the buffalo didn't roam, Texas took a leading role in saving these magnificent creatures. Here's how it came about. In the early 1900s, the U.S. Army, which patrolled the park in those days, estimated that there were just 23 bison left in Yellowstone. They believed that those might be all the bison that remained in the whole of the wild, wild West. Just 100 years before, there had been some 30 million of them on the American plains.                                                                                                                                                                                                                                                                                                                                     Despite efforts to protect the Yellowstone  herd, the poachers poached away. After all, one impressive bison head could fetch $2,000 to forever gaze across a bar. That's $60,000 in todays money. After the Army managed to intimidate and scare off most of the poachers, Yellowstone needed some good, pure-bred bulls to rebuild the meager herd. The problem was that most of the bison then in captivity were cattalo--a mixture of bison, or buffalo, and cattle. But in Texas the famous Charles Goodnight-perhaps the most omnipresent figure in Texas history--had his own herd of bison. His herd had been gathered and nurtured by his wife, Mary Ann Goodnight, who personally saw to it that the orphans found wandering the ranch were saved and protected. And so Goodnight, at his own expense, sent three fine, purebred bulls up to Yellowstone to help rebuild that herd.                                                                                                                                                                                                                                                                                           It worked. Today there are some 5,500 bison in Yellowstone, thanks in part to Goodnight. True, Congress created Yellowstone, and the U.S. Army did its part to help protect the herd from poachers in that enormous park. But it was Goodnight's gift that truly saved the magestic creatures. In fact, Yellowstone now says it has too many bison, and the herd needs culling. If you add those to the herd that Goodnight donated to Caprock Canyons State Park in Texas, you can say that Texas is largely responsible for bringing bison back from the brink of absolute extinction. And that's no bull.
