Cliffs and Beaches

Natural coastal cliffs and beaches mark the place where the land meets the sea.
They are a crucial biological interface between aquatic ecosystems and the land,
and a remarkable number of living things depend upon them at some point in their
lives. These habitats have declined considerably in the Chesapeake Bay region
because of extensive shoreline stabilization.
Yet it is the erosion processes
that man-made stabilization seeks to curb that make these dynamic habitats
unique. The constant wear of wind and tide creates a harsh environment in which
some creatures and plants have developed unique strategies for survival.
Some
of our rarest and most threatened species, notably our two species of Federally
threatened tiger beetles and the globally rare plant seabeach amaranth, are
restricted to natural beaches or cliffs. Their conservation - along with that of
many birds, plants, and invertebrate animals - is dependent upon protecting
these habitats in their natural state. The Landowner Incentive Program is
funding the control of invasive plants such as Phragmites to benefit rare tiger
beetles along the Calvert County shoreline.
Another species that depends upon natural sandy beaches is the diamondback
terrapin. This beautiful animal, familiar to many as the mascot of the
University of Maryland, requires sandy beaches in order to dig nests and lay
eggs during the summer. Unfortunately, much of the terrapin's native nesting
ground has been destroyed through the construction of armored shoreline,
including bulkheads and rip-rap. LIP is funding a project in Dorchester County
to restore a prime terrapin nesting site.
