A heavily polluted mountainside near Palmerton is being restored using warm season grasses, which have different proportions of the stable isotopes of carbon than the surrounding vegetation. Animals that consume these grasses will have similar isotopic ratios. By analyzing invertebrates and tissue from vertebrates, we will study the food web as it is reassembled during restoration.
