Appendix 2 Volume Three 3. D’Urville Islands Abiotic Values - Highly exposed islands and headlands, which display steep and exposed rocky sea cliffs and windswept coastlines. - Strong currents sweep around the top of D'Urville Island and through Stephens Passage. - The islands are above water remnants of ancient ridges and spurs directly associated with the drowned valley system which formed the Marlborough Sounds. - Outer Islands are largely made up of sedimentary strata and schist. Biotic Values - Isolated Islands contain unique species including tuatara and king shag. - Very low levels of modification to all islands which contain endemic shrublands, herbfields and tussockland communities. - Largely unmodified and highly diverse near-shore coastal marine environment ranging from very exposed to very sheltered shores. - Complex rock reef and high current habitats distinguish the marine area. - Extensive bryozoan coral beds, notably between Rangitoto Islands and D'Urville Island. - Trio and Stephens Islands are predator free. - Spectacular coastal cliffs on Rangitoto and Stephens Islands. Experiential - Exceptional characteristics that are clearly linked with the area's exposure to the Values sea, and its rugged and exposed appearance. - Limited or no levels of modification. 4. Chetwode and Titi Islands Abiotic Values - The Chetwode and Titi Islands are generally characterised by steep rock scarps and exposed cliffs. - Many spectacular rock stacks are present at the southern end of the Chetwode Islands. Biotic Values - Titi and Chetwode Islands are predator free. - Very low levels of modification to all islands, which contain endemic shrublands, herbfields and tussockland communities. Steep rock scarps contain tough native shrubs and species endemic to the region such as the Cook Strait Kowhai. - The Chetwodes are the most ecologically significant islands in the Marlborough Sounds harbouring the yellow crowned parakeet, mohua, robin, kaka and rare indigenous vegetation and plant species. - Near-shore areas retain high marine natural values, including high current habitats supporting bryozoan corals, sponges, hydroids, ascidians, horse mussels and associated species (e.g. fish). Experiential - Characteristics clearly linked with the area's exposure to the sea, rugged and Values exposed in appearance. 5. Eastern Arapawa Island and The Brothers Abiotic Values - Dynamic features and processes are largely driven by southerly winds and swells which impact upon the exposed eastern shores, creating a very high energy coastline. - Strong tidal currents are a feature especially around The Brothers Islands, near Tory Channel and off major headlands. Biotic Values - The eastern flanks of Arapawa Island support some of the best remaining examples of Cook Strait mixed broad-leaved forests and are nationally important, especially as possum-free environments.
