The biological and evolutionary significance of serpentine habitats has long been recognized in the ecological community due to the often unique endemic flora in these areas of high local biodiversity. The results from geological, pedological and vegetation properties indicate grassland areas that were first invaded by coniferous species and are now experiencing an increased dominance by Acer, Nyssa and more mesic Quercus and Fagus tree species. This ecosystem, which has taken centuries to millennia to evolve, appears to be fading from ecological memory in just a few decades.
