“…Tortoises are also ‘de-weeders’, and their faeces and urine provide vital soil nutrients, making tortoises ideal candidates for rewilding projects on Mauritius and Rodrigues (Griffiths et al 2011; Griffiths 2014; Hume 2014b), Madagascar (Pedrono et al 2013), Galápagos (Gibbs et al 2008) and in the Caribbean (Hansen et al 2010). In New Zealand, the extant North Island kokako ( Callaeas wilsoni ) has been released on Secretary Island in order to restore the ecological functions of the extinct South Island kokako ( Callaeas cinerea ; Seddon et al 2012). Use of phylogenetic relatives in order to restore extinct plants and birds has also been advocated for Lord Howe Island (Hutton et al 2007).…”

Island extinctions: processes, patterns, and potential for ecosystem restoration

SUMMARYExtinctions have altered island ecosystems throughout the late Quaternary. Here, we review the main historic drivers of extinctions on islands, patterns in extinction chronologies between islands, and the potential for restoring ecosystems through reintroducing extirpated species. While some extinctions have been caused by climatic and environmental change, most have been caused by anthropogenic impacts. We propose a general model to describe patterns in these anthropogenic island extinctions. Hunting, habitat loss and the introduction of invasive predators accompanied prehistoric settlement and caused declines of endemic island species. Later settlement by European colonists brought further land development, a different suite of predators and new drivers, leading to more extinctions. Extinctions alter ecological networks, causing ripple effects for islands through the loss of ecosystem processes, functions and interactions between species. Reintroduction of extirpated species can help restore ecosystem function and processes, and can be guided by palaeoecology. However, reintroduction projects must also consider the cultural, social and economic needs of humans now inhabiting the islands and ensure resilience against future environmental and climate change.

“…Translocation proposals must provide the rationale and justification for translocation, and consider logistics, viability of both source and transferred populations, habitat requirements, welfare needs during transfer, disease screening needs, and funding [42]. Increasingly, genetic issues need to be addressed as each translocation event is, potentially, a genetic bottleneck [43].…”

Public participation theory assumes that empowering communities leads to enduring support for new initiatives. The New Zealand Biodiversity Strategy, approved in 2000, embraces this assumption and includes goals for community involvement in resolving threats to native flora and fauna. Over the last 20 years, community-based ecological restoration groups have proliferated, with between 600 and 4000 identified. Many of these groups control invasive mammals, and often include protection of native species and species reintroductions as goals. Such activities involve the groups in "wicked" problems with uncertain biological and social outcomes, plus technical challenges for implementing and measuring results. The solution might be to develop a citizen science approach, although this requires institutional support. We conducted a web-based audit of 50 community groups participating in ecological restoration projects in northern New Zealand. We found great variation in the quality of information provided by the groups, with none identifying strategic milestones and progress towards them. We concluded that, at best, many group members are accidental scientists rather than citizen scientists. Furthermore, the way community efforts are reflected in biodiversity responses is often unclear. The situation may be improved with a new approach to data gathering, training, and analyses.

“…Wildlife translocation remains a popular tool for re-establishing declining or extirpated species and the science guiding the application of this tool has progressed (Seddon et al ., 2007, 2012; Batson et al ., 2015). Despite increased knowledge and improved procedures, translocations, which involve the introduction of naive hosts into new environments with novel pathogens, invariably pose an increased risk of disease (Ballou, 1993; Viggers et al ., 1993; Gerhold and Hickling, 2016).…”

Genetic analyses of the parasitic nematode,Parelaphostrongylus tenuis, in Missouri and Kentucky reveal unexpected levels of diversity and population differentiation

Wildlife translocations, which involve the introduction of naive hosts into new environments with novel pathogens, invariably pose an increased risk of disease. The meningeal worm Parelaphostrongylus tenuis is a nematode parasite of the white-tailed deer (Odocoileus virginianus), which serves as its primary host and rarely suffers adverse effects from infection. Attempts to restore elk (Cervus canadensis) to the eastern US have been hampered by disease caused by this parasite. Using DNA sequence data from mitochondrial and nuclear genes, we examined the hypothesis that elk translocated within the eastern US could be exposed to novel genetic variants of P. tenuis by detailing the genetic structure among P. tenuis taken from white-tailed deer and elk at a source (Kentucky) and a release site (Missouri). We found high levels of diversity at both mitochondrial and nuclear DNA in Missouri and Kentucky and a high level of differentiation between states. Our results highlight the importance of considering the potential for increased disease risk from exposure to novel strains of parasites in the decision-making process of a reintroduction or restoration.
