Spanish moss, which is not really a moss (it's a member of the bromeliad family) has had its ups and downs in the area. It takes its moisture from the rain and its nutrients from the air, so it's not a parasite to the tree as believed by some. It was once called "the air plant" and is believed to be a bioindicator of problems in air quality.
For commercial purposes, it has been used as insulation, mattress and upholstery stuffing, mulch and even in evaporative coolers, the forerunners of air conditioners.
I remember a movie being made near Madisonville where the director called for more "moss" on the trees in the background, so truckloads were brought in and the set decorators went to work hanging the moss. Nothing says "Deep South" like moss swaying in the breeze over your actors' heads.
