Steepheads

 
  Steepheads are one of the most awesome, unique, diverse and sensitive ecosystems in the entire Southeast!  Steephead's are deep ravines that occur in Upland Sandhill or Clayhill habitats.  A steephead itself is like a giant living organism or ecosystem.  At the head of steephead ravines are springs or seepages of clear, filtered water which emerge from the ground and constantly erode the gullies headward.  The growth of steepheads over time is like placing your hand in a sandbox and moving your hand through the sand while spreading fingers.  Some steepheads can have multiple ravines, all with numerous springs and seepages.  As steepheads age the valleys grow longer and deeper.  Steephead ravines can be 80 feet or more in depth and are truly canyon's in Florida's low overall elevation!

  Steephead's provide very unique and sheltered habitat for many specially adapted and delicate species of animals and plants.  Steepheads abound in amphibian species because of their cooler and insolated nature.  During the heat of the summer, steepheads are much cooler than the surrounding uplands because of their deeper elevation and their heavily shaded overstory of hardwoods.  Steepheads have lush, dense vegetation which provides shelter and cover for many species of animals, especially frogs and salamanders.  On the bottom of steephead valleys, along small clear-running streams, often lay dense carpets of spagnum moss which is heaven for many salamander species!

  Numerous uncommon, rare and endangered plant species occur in steephead ravines, some of which are found in mountainous areas 500-1000+ miles north of Florida.  During the Ice-Ages, as glaciers pushed northern vegetation southward, these plants remained in the sheltered ravines when the glaciers retreated.  Some of these interesting species include: the Florida Torreya tree, the Florida Yew, Ashe Magnolia, Pyramid Magnolia, Mountain Laurel, various Azalea species, Florida Anise, Beech trees, White oak trees and a variety of other northern hardwood trees.  Many Appalachian mountain and northern herbaceous plant species are also found on Steephead slopes and ravines such as: several Trillium species, Trout lilies, Wild Ginger, and a variety of orchids.

Torreya Guardians is a self-organized group of naturalists, botanists, ecologists, and others with a deep concern for biodiversity protection, who have chosen to use the internet as a tool for discussing ideas, posting plans, and taking a variety of actions in behalf of our most endangered conifer tree: Torreya taxifolia.
