Restoring the Northern Riffleshell

Endangered throughout its range, the surviving Pennsylvania populations are some of the best remaining in the world. Water pollution, dam construction and dredging are the major causes for its decline, but other threats include stream sedimentation, channelization and reduced host fish populations. The Epioblasma mussles are some of the most environmentally sensitive species in North America. More »

    The small whorled pogonia (Isotria medeoloides) is a rare orchid that grows in older hardwood forests of beech, birch, maple, oak, and hickory with an open understory. The primary threat to the small whorled pogonia is the past and continuing loss of populations when their habitat is developed for urban expansion. And as is the case with all rare orchids, the small whorled pogonia is vulnerable to collecting for commercial or personal use.

    At only about 4 inches long, the bog turtle (Clemmys (Glyptemys) muhlenbergii) is one of North America’s smallest turtles. This federally threatened species lives in a mosaic of open, sunny, springfed wetlands and scattered dry areas. The variety of wet and dry places meets all the turtle’s basic needs. Sunny open areas provide the warmth needed to regulate the turtle’s body temperature and incubate its eggs, while soft muddy areas allow turtles to escape from predators and extreme temperatures.
