Spatial patterns and habitat use of penned and hard-released arboreal geckos translocated to an offshore island free of introduced mammals

Temporary penning prior to release is a strategy increasingly being used in lizard translocations to improve site fidelity and increase chances of translocation success. However, it is yet to be tested on a range of lizard taxa. Between 2015 and 2018, 49 individuals of a New Zealand endemic arboreal gecko species (ngahere gecko, Mokopirirakau “southern North Island”) were translocated to mammal-free Mana Island near Wellington as mitigation for a development project.

Roads and wildlife: the need for evidence-based decisions; New Zealand bats as a case study

Roads and associated land transport activities can affect a wide range of indigenous terrestrial vertebrate species. National legislation, particularly the Resource Management Act 1991, requires that developers ‘avoid, remedy or mitigate’ the adverse environmental effects of their activities. How these effects are identified and managed in New Zealand varies because regulators and land transport contractors deal with these issues on a case-by-case basis.

Compensating for ecological harm – the state of play in New Zealand

Ecological compensation involves measures to create positive conservation outcomes intended to offset the residual impacts of development (e.g. restoration planting, pest control). Rarely, however, have the exchanges arranged been subject to objective assessment. Here we assess 110 cases of ecological compensation involving diverse New Zealand ecosystems on the basis of how they addressed the six key implementation issues identified by McKenney and Kiesecker (2010: Environmental Management 45: 165–176): equivalence, location (i.e.
