Marlborough Sounds Resource Management Plan 5 Arapawa Tauhinui, Black Beech, Fluttering Shearwater, Powelliph anta ‘bicolor’ , Eastern Sounds, Dry, Weakly Schi stose Ecosystem Steep to moderately steep dry dissected coastal hill slopes are a feature of this land ecosystem with several islands, a highly indented coast, and confined coastal inlets, beaches and undulating to rolling prograding inlet heads and minor fans filling the valley floors. Baserock is weakly developed schist with minor sedimentary layers, with a valley overlay of alluvium in places. Exposure and maritime influence is generally high due to landmass being surrounded by sea, the elevation low. Fragmented vegetation patterns, with much scrubland.
