On October 11, 1974, Congress grafted a new and controversial branch onto the National Park System family tree by creating the first two National Preserves – Big Thicket National Preserve in Texas and Big Cypress National Preserve in Florida. Big Thicket, like its Florida cousin, is now a nicely maturing “thirtysomething” park with a lot of visitor appeal.

National parks are great places to take photos, and there are some opportunities for unusual images at the Big Thicket National Preserve in southeast Texas. But even after working there as a ranger for several years I was surprised one afternoon to witness the reported sighting of a large mammal not previously known to inhabit the area.

At Big Thicket National Park, a man involved in a drug transaction started to resist arrest. He abruptly changed his mind when ranger Johnny Stafford drew his Taser and displayed the spark. Did the miscreant holler “Don’t taze me, bro!”?

Big Thicket National Preserve, a rich crucible of biodiversity, would double in size under legislation introduced by a congressman from Texas.

Imagine taking the time to go into your backyard, or the nearby woods, or even a pond close to your home, to catalog all the life you found in it. Not just the deer or snakes or fish, but the birds and insects, reptiles, plants and fungi and everything else biological or botanic. Imagine how fascinating that would be. At Great Smoky Mountains National Park they've been working on just that, and what they've found has been incredible.
