Purpose The purpose of this paper is to examine the role of the International Union for the Conservation of Nature (IUCN) Red List of Threatened Species in achieving biodiversity conservation and preventing the extinction of species. The Red List is a calculative device that classifies species in terms of their exposure to the risk of extinction. Design/methodology/approach The paper draws on theorising in the Social Studies of Finance literature to analyse the Red List in terms of how it frames a space of calculability for species extinction. The analysis then traces the ways that this framing has overflowed, creating conditions for calculative innovations, such that assemblages of humans and calculative devices (i.e. agencements) are constructed with collective capabilities to act to conserve biodiversity and prevent species extinctions. Findings This paper has traced three ways that the Red List frame has overflowed, leading to calculative innovations and the construction of new agencements. The overflow of relations between the quality of “extinction risk”, produced by the Red List, and other qualities, such as location, has created opportunities for conservationists to develop agencements capable of formulating conservation strategies. The overflow of relations between the identity of the “threatened species”, produced by the Red List, and other features of evaluated species, has created opportunities for conservationists to develop agencements capable of impelling participation in conservation efforts. The overflow of ecological relations between species, discarded by the Red List’s hierarchical metrology of extinction risk classifications, has created opportunities for conservationists to develop agencements capable of confronting society with the reality of an extinction crisis. Originality/value The paper contributes to the accounting for biodiversity literature by addressing its fundamental challenge: explaining how accounting can create conditions within society in which biodiversity conservation is made possible.

Invasive Mammals

More than US$21 billion is spent annually on biodiversity conservation. Despite their importance for preventing or slowing extinctions and preserving biodiversity, conservation interventions are rarely assessed systematically for their global impact. Islands house a disproportionately higher amount of biodiversity compared with mainlands, much of which is highly threatened with extinction. Indeed, island species make up nearly two-thirds of recent extinctions. Islands therefore are critical targets of conservation. We used an extensive literature and database review paired with expert interviews to estimate the global benefits of an increasingly used conservation action to stem biodiversity loss: eradication of invasive mammals on islands. We found 236 native terrestrial insular faunal species (596 populations) that benefitted through positive demographic and/or distributional responses from 251 eradications of invasive mammals on 181 islands. Seven native species (eight populations) were negatively impacted by invasive mammal eradication. Four threatened species had their International Union for the Conservation of Nature (IUCN) Red List extinction-risk categories reduced as a direct result of invasive mammal eradication, and no species moved to a higher extinction-risk category. We predict that 107 highly threatened birds, mammals, and reptiles on the IUCN Red List—6% of all these highly threatened species—likely have benefitted from invasive mammal eradications on islands. Because monitoring of eradication outcomes is sporadic and limited, the impacts of global eradications are likely greater than we report here. Our results highlight the importance of invasive mammal eradication on islands for protecting the world's most imperiled fauna.

Endemic Flora

Climate change poses a great challenge for biodiversity conservation. Several studies exist regarding climate change’s impacts on European plants, yet none has investigated how climate change will affect the extinction risk of the entire endemic flora of an island biodiversity hotspot, with intense human disturbance. Our aim is to assess climate change’s impacts on the biodiversity patterns of the endemic plants of Crete (S Aegean) and provide a case-study upon which a climate-smart conservation planning strategy might be set. We employed a variety of macroecological analyses and estimated the current and future biodiversity, conservation and extinction hotspots in Crete. We evaluated the effectiveness of climatic refugia and the Natura 2000 network of protected areas (PAs) for protecting the most vulnerable species and identified the taxa of conservation priority based on the Evolutionary Distinct and Globally Endangered (EDGE) index. The results revealed that high altitude areas of Cretan mountains constitute biodiversity hotspots and areas of high conservation and evolutionary value. Due to the “escalator to extinction” phenomenon, these areas are projected to become diversity “death-zones” and should thus be prioritised. Conservation efforts should be targeted at areas with overlaps among PAs and climatic refugia, characterised by high diversity and EDGE scores. This conservation-prioritisation planning will allow the preservation of evolutionary heritage, trait diversity and future ecosystem services for human well-being and acts as a pilot for similar regions worldwide.

AbstractExtinction threatens many species, yet few factors predict this risk across the plant Tree of Life (ToL). Taxon age is one factor that may associate with extinction if occupancy of geographic and adaptive zones varies with time, but evidence for such an association has been equivocal. Age-dependent occupancy can also influence diversification rates and thus extinction risk where new taxa have small range and population sizes. Here we analysed 509 well-sampled genera from across the plant ToL. We found that a greater proportion of species were threatened by extinction in younger and faster-diversifying genera. Repeating our analyses in two large, well-sampled groups, we found that extinction risk increased with evolutionary age in conifer species but not palms. Potential range size decreased in older, non-threatened conifers more strongly than in threatened taxa, suggesting that range size dynamics may explain differing patterns of extinction risk across the ToL with consequences for biodiversity conservation.

Negative Impacts

Abstract Wildlife commodification can generate benefits for biodiversity conservation, but it also has negative impacts; overexploitation of wildlife is currently one of the biggest drivers of vertebrate extinction risk. In the present article, we highlight 10 issues that in our experience impede sustainable and humane wildlife trade. Given humanity's increasing demands on the natural world we question whether many aspects of wildlife trade can be compatible with appropriate standards for biodiversity conservation and animal welfare, and suggest that too many elements of wildlife trade as it currently stands are not sustainable for wildlife or for the livelihoods that it supports. We suggest that the onus should be on traders to demonstrate that wildlife use is sustainable, humane, and safe (with respect to disease and invasion risk), rather than on conservationists to demonstrate it is not, that there is a need for a broad acceptance of responsibility and, ultimately, widespread behavior change. We urge conservationists, practitioners, and others to take bold, progressive steps to reach consensus and action.

Conservation Policies

Gaps in biodiversity conservation management within the Conservation Area that are the responsibility of the central government and outside the Conservation Areas or as the Essential Ecosystems Area (EEA) which are the authority of the Regional Government, have caused various spatial conflicts between wildlife /wild plants and land management activities. Several obstacles faced by the Local Government to conduct its authority to manage (EEA), caused the number and area of EEA determined by the Local Government to be still low. At present only 703,000 ha are determined from the 67 million ha indicated by EEA. This study aims to overview biodiversity conservation policies by local governments and company perceptions in implementing conservation policies and formulate strategies for optimizing the role of Local Governments. From the results of this study, there has not been found any legal umbrella for the implementation of Law number 23/ 2014 related to the conservation of important ecosystems in the regions. This regulatory vacuum leaves the local government in a dilemma for continuing various conservation programs. By using a SWOT to the internal strategic environment and external stratetegic environment of the Environment and Forestry Service, Bengkulu Province , as well as using an analysis of company perceptions of the conservation policies regulatary , this study has been formulated a “survival strategy” through collaboration between the Central Government, Local Governments and the Private Sector to optimize the role of Local Government’s to establish EEA in the regions.Keywords: Management gaps, Essential Ecosystems Area (EEA), Conservation Areas, SWOT analysis and perception analysis

The coverage of natural history in British newspapers has evolved from a “Nature notes” format – usually a regular column submitted by a local amateur naturalist – to professional, larger-format, presentations by dedicated environmental correspondents. Not all such environmental correspondents, however, have natural-history expertise or even a scientific background. Yorkshire's Michael Clegg was a man who had a life-long love of nature wedded to a desire to communicate that passion. He moved from a secure position in the museum world (with a journalistic sideline) to become a freelance newspaper journalist and (subsequently) commentator on radio and television dealing with, and campaigning on, environmental issues full-time. As such, he exemplified the transition in how natural history coverage in the media evolved in the final decades of the twentieth century reflecting modern concerns about biodiversity, conservation, pollution and sustainable development.
