These drainage systems and ba~kswamps, and their assoc iated vegetation communities, constitute the bul k of the Peninsula's freshwater wetlands and as such play an important role as wa,tering sources and habitat for birds and other fauna. The Cobourg Peninsula Plan of Management takes cognizance of the principles .of Aust C ~----' ral ian-Japane,se agreemen,ts to protect migratory waterfowl "habitat, especially in the light of these wet lands. The botanical diversi,ty of these communities ha.s not been i~ve st iga ted, full y to date and there is a ,high probabil ity that t"hey will conta in a number of as yet undescribed species.
