Although New Zealand's native fauna shares a Gondwana origin with that of Australia, there are major differences between our countries. The near-absence of land mammals and the restricted biodiversity and habitat range of New Zealand, contrast with the species-rich fauna and habitat variety of Australia. Both countries share an unenviable extinction record, particularly birds in New Zealand and mammals in Australia. Introduced mammals, often interacting with habitat destruction, have frequently been responsible for these losses in New Zealand. In some places, entire vertebrate foraging guilds have disappeared. On the mainland, control of introduced mammals has had limited success but a steadily increasing number of islands have been cleared of alien mammals. This has created new opportunities for translocating threatened species of native vertebrates and invertebrates to pest-free islands. It has also created options for substituting an ecologically similar species for one that is extinct, thus potentially achieving a more comprehensive restoration. Recent progress with island restoration has stimulated a "mainland island" strategy involving simultaneous intensive control of several pest mammals within a limited area that is then used to re-establish viable populations of threatened species. Examples are given to illustrate these conservation actions.

Threatened Status

Despite the scarcity of funding for species conservation programmes, estimation of the cost of threatened species programmes occurs in only a few countries. This paper examines the reasons for the lack of species programme cost estimates and the likely impacts of this on conservation management. We report methodology used to estimate cost for eleven New Zealand species programmes and their estimated costs over a ten year period. Differences between species in the costs of the programmes and the breakdown of the costs are highlighted. The estimated costs are compared with expected levels of expenditure on each species to illustrate the existence of a budget constraint for threatened species. The likely effects of cost of species conservation exceeding expenditures on species conservation are examined. Annual cost data is used together with information on rate of conservation progress to estimate time and total cost for each species to reach Not Threatened status.

Effective Conservation

Threatened species' lists have been consistently reviewed as easily misused, inappropriately applied, counterproductive, and reflecting changes in knowledge more often than changes in threat status (Burgman, 2002; de Grammont and Cuaron, 2006; Possingham et al., 2002; Seminoff and Shanker, 2008). However, with limited resources to deal with endangered species, effective conservation decision-making needs a means of determining where priorities lie. The EDGE list of the world's most ?Evolutionary Distinct? and ?Globally Endangered? amphibians ranks New Zealand's endemic Archey's Frog Leiopelma archeyi at the top of its list (www.edgeofexistence.org/ amphibians/top_100.php). What role should this ranking or any other threatened species list play in determining conservation priorities in New Zealand?

Genomic Markers

1AbstractGenetic swamping resulting from interspecific hybridisation can increase extinction risk for threatened species. The development of high-throughput and reduced-representation genomic sequencing and analyses to generate large numbers of high resolution genomic markers has the potential to reveal introgression previously undetected using small numbers of genetic markers. However, few studies to date have implemented genomic tools to assess the impacts of interspecific hybridisation in threatened species. Here we investigate the utility of genome-wide single nucleotide polymorphisms (SNPs) to detect introgression resulting from past interspecific hybridisation in one of the world’s rarest birds. Anthropogenic impacts have resulted in hybridisation and subsequent backcrossing of the critically endangered Aotearoa New Zealand endemic kakī (black stilts; Himantopus novaezelandiae) with the non-threatened self-introduced congeneric poaka (Aotearoa New Zealand population of pied stilts, Himantopus himantopus leucocephalus), yet genetic analyses with a limited set of microsatellite markers revealed no evidence of introgression of poaka genetic material in kakī, excluding one individual. We use genomic data for ~63% of the wild adult kakī population to reassess the extent of introgression resulting from hybridisation between kakī and poaka. Consistent with previous genetic analyses, we detected no introgression from poaka into kakī. These collective results indicate that, for kakī, existing microsatellite markers provide a robust, cost-effective approach to detect cryptic hybrids. Further, for well-differentiated species, the use of genomic markers may not be required to detect admixed individuals.

Biodiversity Changes

Recent analyses (Clout, 2001; Cullen et al. 2005; Hartley, 1997; Joseph et al. 2008; Joseph et al. 2009) of the management of New Zealand?s biodiversity have highlighted the challenge of allocating limited resources, especially the funding of threatened species. Our essay includes frequent citation of Joseph et al. (2008, 2009) as the Project Prioritization Protocol (PPP) modal proposed in their papers is co-written by Department of Conservation (DOC) staff, and may be the metric used in future allocation of resources to New Zealand?s threatened species. Limited resourcing of threatened species management and recovery is a worldwide problem, extensively documented in the conservation literature (Spring et al. 2007; Sutherland, 2009). Reviews of conservation management practices (Craig and Stewart, 1994; Sutherland, 2009; Sutherland et al. 2004; Ussher, 1999) have called for the justification of conservation research by quantifying biodiversity changes and testing solutions. Therefore it is appropriate that novel strategies such as those presented by Joseph et al. (2008, 2009) are available for assessment. Any suggestions for improvement must engage a full debate on the current demands on natural resources (Sarukhan and Whyte, 2005) and the emerging threats to biodiversity, such as climate change (Kostyack and Rohlf, 2008). Development and Implementation of management strategies for threatened species need to be cognizant of not only the ecological (Clark et al. 1994; Tear et al. 1993) needs of threatened species, but also cultural (Charnley, 2006; Craig and Stewart, 1994; McBride et al. 2007) and economic (Craig, 1998; Cullen et al. 2005; Moran, 2003; Perhans et al. 2008; Sinden, 2004) factors.
