Turakirae Head Scientific Reserve - a photo on Flickriver

            Turakirae Head Scientific Reserve, Wellington region, New Zealand.
 The name Turakirae tells us that this is the headland (rae) where the Rimutaka Range comes down (turaki) to the sea. Turakirae Head Scientific Reserve provides valuable habitat for a variety of plants and wildlife, most notably New Zealand fur seals, and preserves a well-defined sequence of earthquake-raised beaches. The five earthquake-raised beaches are internationally-renowned in scientific circles for the continuous record they provide of geological upheaval over the past 7000 years.
The most recent uplift occurred in 1855 when an earthquake measuring 8 on the Richter scale raised the beach 2.5 metres at Turakirae Head and 1.7 metres in Wellington Harbour. The second beach ridge was uplifted by a similar ’quake around 1460 AD. This is now about 8 metres above sea level and is separated from the 1855 beach by a platform of large boulders. A similar platform separates the third beach at about 16 metres above sea level. This beach is estimated to have been uplifted about 3000 years ago. Two other ridges are mostly obscured by screes from the steep slopes behind. They occur at 22 and 25 metres above sea level. Evidence of much earlier uplift can be seen in the hills west of the Orongorongo River.
Up to 500 New Zealand fur seals stay at Turakirae Head each winter. The colony mainly comprises juvenile males, which spend their time here building up condition before moving to breeding colonies in other areas. During the breeding season they will not eat for three months or more, living off the fat reserves they build up over winter. This colony began in 1950 and has steadily increased since then to become the largest haulout on the south Wellington coast.
Turakirae Head Scientific Reserve also provides habitat for a variety of native birds and reptiles. Banded dotterel, caspian tern and variable oystercatcher are among the bird species that may be observed. Copper skink, spotted skink, common skink and common gecko are all present within the reserve.
The vegetation within the Turakirae Head Scientific Reserve consists of a mixture of salt tolerant herbs, tussock and reed associations, dune associations and coastal forest. Fire, both pre-European and more recent, has been the principal environmental factor influencing the present vegetation pattern. The vegetation is still subject to grazing by sheep, cattle and rabbits (all introduced animals). New Zealand plants evolved without mammalian herbivores so this grazing represents a threat to some species. 
A nationally-threatened plant, the shrubby tororaro, Muehlenbeckia astonii, occurs within the reserve. A new population of shrubby tororaro was established at Turakirae Head in 1998 as part of a programme to avert the extinction of the species.
