The New Zealand Forest Service once managed Pureora Forest for intensive harvest of native timber trees and replanting with Pinus radiata, until all logging was stopped in 1978. They commissioned a 5 year survey of small mammals in Pureora 1982–87 describing the effects of past logging/replanting on the prospects of pest control and post-logging restoration. The same field protocols previously used in beech forests were applied again, with very different results. By contrast with cooler beech forests, where mice are abundant but only after a seedfall year (Chap. 5 ), in richer and warmer forests such as Pureora the dominant rodents every year are rats. Among a total of 2740 captures, a 5-year survey collected 1793 ship rats (Rattus rattus), and 522 mice (Mus musculus), but only 57 stoats (Mustela erminea), 16 weasels (M. nivalis) and 11 ferrets (M. furo). The average stoat reached the age of 15 months, after a first-year survival rate of about 24%. But the proportion of first-years declined from 52% to 27% over the 5 years, showing that trapping stoats in non-beech forests can exceed their natural replacement rate. Pureora is now part of the Department of Conservation estate.
