Ancient totara dune forest becomes new Southland reserve

In the far south of the South Island, in Otatara, Southland, there is a totara dune forest where ancient trees bend and twist and brace themselves against the prevailing winds.

Study compares beetle and wētā responses to mammal eradication

September 3, 2020 by Kate Guthrie

Study compares beetle and wētā responses to mammal eradication

Wētā are one of our most studied insects and are regarded as ‘bioindicators’ of the health of forest ecosystems. So when introduced predators – including mice – were removed from Maungatautari, the response of the local wētā population was followed closely by researchers. Female Auckland tree … [Read more...] about Study compares beetle and wētā responses to mammal eradication
