Critters of Ohinau Island

  • A pair of Mercury Island tusked weta on the forest floor at night, Ohinau Island, January 2014. The large male (with tusks) is on the left; the long appendage at the rear of the female is her ovipositor, used to lay eggs in the soil. Image: Colin Miskelly, Te Papa
  • The entire range of Mercury Island tusked weta. This rare species survived only on 13 ha Middle Island, the small island left of centre in this image. Following eradications of Pacific rats (kiore) on nearby larger islands, they were successfully translocated to Cuvier Island (on the distant horizon), Korapuki Island (immediately below Cuvier Island, and to the lower right of Great Mercury Island), Stanley Island (the large island to the right of Middle Island), the western end of Double Island (which appears as two small islands to the right of Stanley Island), Red Mercury Island (the long, low island on the right), and Ohinau Island (foreground).

Te Papa vertebrate curator Dr Colin Miskelly recently spent 12 days on Ohinau Island (east of Whitianga, Coromandel Peninsula) as part of a Te Papa seabird research team. This blog reports on some of the more impressive invertebrate species that he found on the island. Ohinau is a 43 ha forested island owned by Ngati… Read more »

Keeping track of our protected species populations and their distribution is one of the tasks of biologists, and this summer Te Papa scientists surveyed sites in the Mercury Islands group for seabird populations. Flesh-footed shearwaters Puffinus carneipes breed throughout northern New Zealand, with a total population size in New Zealand of about 10,000 to 15,000 pairs… Read more »

Past and present fauna of Mt Owen, north-west Nelson

As well as impressive plants, Mount Owen and the Marino Mountains are also zoologically interesting. The wet weather may have prevented us reaching the summit of Mount Owen but it did bring out the slugs and snails. We spotted a giant leaf-veined slug (Amphikonophora gigantea) beside the track on the lower flanks of the mountain…. Read more »

Over the holidays I was fortunate to spend a few days botanising the Marino Mountains, including Mount Owen, in north-west Nelson’s Kahurangi National Park.  Kahurangi National Park  is one of the most botanically interesting regions in New Zealand. Nearly half of New Zealand’s native plant species and 80% of our alpine species are found there…. Read more »

From the 23rd-30th of December 2013 I was given the opportunity to join Rodney Russ and his team at Heritage Expeditions on board the Spirit of Enderby for a week long adventure to the New Zealand Subantarctic Islands.
