The Wisent Prince

Richard Prinz zu Sayn-Wittgenstein-Berleburg, a German prince, is reintroducing wisent, or European bison (Bison bonasus) into the German wild.  These bovine cousins of the American bison (Bison bison) once roamed the woodlands of Europe, but became extinct in the wild largely due to overhunting and loss of habitat.  Although not an example of "deextinction" per se, the wisent may have much to teach about how once-and-future megamammals readapt to the wild.
