Such is the daily routine of Crum and his savvy snake trackers on “Guardians of the Glades,” a new six-episode series debuting on Tuesday, May 28, on the Discovery Channel. The show follows Crum and his crew — Clark, survivalist Tom Cobb, “swamp guru” Jay Staff and rookie Brittany Borges — deep into the mangroves as they capture and subdue Burmese pythons, which have ravaged mammal and bird species in the vast swamps of South Florida.
