Pressure/threats to key biodiversity

Human disturbance – Yes - Overall disturbance to birds on land will be minimal due to inaccessibility of sites to most visitors, however landings by kayakers may present a problem. Also, approaches by small boats and kayaks close to shore can disturb penguins, although in general tour guides will control activity.

Predation by alien species – Yes - Stoats, rats, possibly possums.

Habitat loss or degradation – No

Contamination – Yes - A recent oil spill in the Milford Sound boat harbour (not within the IBA) and the high volume of boat traffic operating within Milford Sound highlights the potential for adverse impact an oil spill would have on marine fauna.

Natural disaster – No
Other – No
