Marlborough Sounds Resource Management Plan 8 Nydia Red Beech, Supplejack, Filmy Ferns, Kakariki, Inner Sounds, Wet, Non to Weakly Schistose Ecosystem Steep to moderately steep terrain is typical of this system with slopes plunging at similar angles into the sea. Small inlets and bays nestle within a range of fine fingers and broad headlands. Within these sheltered valleys lie fans and wetlands accumulating on the alluvium washed down from the non-schistose sedimentary strata and weakly developed schists. Elevation here is moderately high with high rainfall at the tops. Being Inner Sounds, it is relatively sheltered and enjoys a moderate maritime influence. Original forest covers much of the northern part of the ecosystem.
