Kiwi translocation review: are we releasing enough birds and to the right places?

Translocations of kiwi (Apteryx spp.) are one of the most common and growing types of conservation translocations in New Zealand. However, their outcomes remain mostly unpublished, which does not allow for sharing of lessons learnt from past developments. We reviewed 102 kiwi translocations from the 19th century until 2018, and identified factors affecting their outcome. North Island brown kiwi (A.

Resource selection by tuatara following translocation: a comparison of wild-caught and captive-reared juveniles

Animal reintroduction is an important tool for species conservation, but success rates can be low. Comparative studies can be used to identify factors that influence success during translocations. We studied the reintroduction of captive-reared and wild-caught juveniles of an iconic reptile, the tuatara Sphenodon punctatus, on the South Island of New Zealand. We followed juveniles from three treatment groups (wild-caught and from two outdoor head-start facilities, all of the same genetic stock) during the initial five months of the establishment phase.

Impacts of invasive house mice on post-release survival of translocated lizards

Invasive house mice (Mus musculus) have detrimental effects on biodiversity, but their impacts can be difficult to detect and are often unquantified. We measured their effects on survival of a translocated population of an endangered lizard in New Zealand. Twelve captive-reared Otago skinks (Oligosoma otagense) were translocated to a 0.3-ha area of grassland/shrubland cleared of invasive mammals and surrounded by a mammal-resistant fence. Sixteen more skinks were released 2 years later but this was followed by an incursion of mice for c. 160 days.
