There is life in the concrete prairie that surrounds Kauffman Stadium. Despite the surficial sterility of a modern sports complex, a variety of species have developed their own ecosystem in this man-made environment. The conditions seem harsh, but so are many settings more removed from human influence. A grey expanse of pavement simmering in the sun evokes a recently active lava field; a close-mowed lawn mirrors the stubble of a recently grazed grassland; the isolated trees form an oasis, providing shelter and food as in a native savannah. A stadium is a habitat, too, one we can study and enjoy on its own merits.
