Finding sustainable ways to increase the amount of private land protected for biodiversity is a challenge for many conservation organizations. In a number of countries, organizations use 'revolving fund' programs, whereby land is purchased, and then on-sold to conservation-minded owners with a condition to enter into a conservation covenant or easement. The proceeds from sale are then used to purchase, protect and on-sell additional properties, incrementally increasing the amount of protected private land. As the effectiveness of this approach relies upon selecting the right properties, we sought to explore the factors currently considered by practitioners and how these are integrated into decision-making...

David Lindenmayer, Simon Thorn, Reed Noss
The establishment of protected areas is a critical strategy for conserving biodiversity. Key policy directives like the Aichi targets seek to expand protected areas to 17% of the earth's land surface, with calls by some conservation biologists for much more. However, in places such as the USA, Germany and Australia, attempts to increase protected areas are meeting strong resistance from communities, industry groups, and governments. Here we provide case studies of such resistance and suggest four ways to tackle this problem: (1) Broaden the case for protected areas beyond just nature conservation, to include the economic, human health, and other benefits, and translate these into a persuasive business case for protected areas...

An overarching challenge of natural resource management and biodiversity conservation is that relationships between human and nature are difficult to integrate into tools that can effectively guide decision-making. Social-ecological vulnerability offers a valuable framework for identifying and understanding important social-ecological linkages, and the implications of dependencies and other feedback loops in the system. Unfortunately its implementation at local scales has hitherto been limited, due at least in part to the lack of operational tools for spatial representation of social-ecological vulnerability...

Establishing protected areas is the primary goal and tool for preventing irreversible biodiversity loss. However, the effectiveness of protected areas that target specific species has been questioned for some time, because targeting key species for conservation may impair the integral regional pool of species diversity and phylogenetic and functional diversity are seldom considered. We first assessed the efficacy of protected areas in China for the conservation of phylogenetic diversity using the ranges and phylogenies of 2279 terrestrial vertebrates...

David A Keith, H Resit Akçakaya, Nicholas J Murray
Assessments of risk to biodiversity often rely on spatial distributions of species and ecosystems. Range size metrics used extensively in these assessments, such as Area of Occupancy (AOO), are sensitive to measurement scale, prompting proposals to measure them at finer scales, or a variery of different scales based on the shape of the distribution or ecological characteristics of the biota. Despite its dominant role in Red List assessments for decades, appropriate spatial scales of AOO for predicting risks of species extinction or ecosystem collapse remain untested and contentious...

Since its inception, conservation biology has inspired thousands of students, spurred the creation of new initiatives, organizations and agencies, and informed conservation efforts worldwide. Nevertheless, global biodiversity loss is accelerating (Butchart et al. 2010), and our field needs to change to keep pace with mounting challenges. Conservation would benefit if scientists more enthusiastically pushed the institutional boundaries of our field through their efforts to expand their own and others' career options and professional opportunities...

Ecosystem function and resilience are compromised when habitats become fragmented due to land-use change. This has led to national and international conservation strategies aimed at restoring habitat extent and improving functional connectivity (i.e. maintaining dispersal processes). However, biodiversity responses to landscape-scale habitat creation and the relative importance of spatial and temporal scales is poorly understood, and there is disagreement over which conservation strategies should be prioritised...

Although significant resources are being spent researching and fostering the relationship between forests and livelihoods to promote mutually beneficial outcomes, critical gaps in our understanding persist. A core reason for such gaps is that researchers, practitioners, and policy-makers lack the structured space to interact and collaborate, which is essential for effective, interdisciplinary research, practice, and evaluation. Thus, scientific findings, policy recommendations, and measured outcomes have not always been synthesized into deep, systemic understanding; learning from practice and implementation does not easily find its way into scientific analyses--; and science often fails to influence policy...

Over half of globally threatened animal species have experienced rapid geographic range loss. Identifying the parts of species' distributions most vulnerable to extinction would benefit conservation planning. However, previous studies give little consensus on whether ranges decline to the core or edge. Here we build on previous work by using empirical data to examine the position of recent local extinctions within species' geographic ranges, addressing range position as a continuum and exploring the influence of environmental factors...

T R McClanahan, J K Kosgei
Reducing the capture of small fish, discards, and by-catch is a primary concern of fisheries mangers that propose to maintain high yields, species diversity, and associated ecosystem functions. Modified fishing gear is one of the primary ways to reduce by-catch and capture of small fish. The outcomes of gear modification may depend on competition with other gears using similar fishing grounds and resources and the subsequent adoption or defection of fishers using modified gears. We evaluated the adoption, size, catch-per-unit-effort (CPUE), yield, and income responses among gears in a coral reef fishery where a 3-cm escape gap was introduced into traditional traps...

Jordi Janssen, Serene C L Chng
The commercial captive breeding of wildlife is often seen as a potential conservation tool to relieve pressure off wild populations, but laundering of wild-sourced specimens as captive-bred can seriously undermine these and provide a false sense of sustainability. Indonesia has been at the centre of such controversy, therefore we examine Indonesia's captive breeding production plan (CBPP) for 2016. A number of the quotas were found to be based on inaccurate and unrealistic biological parameters, and included species with no reported breeding stock...

Wilderness areas are ecologically intact landscapes predominantly free of human uses, especially industrial scale activities, which result in significant biophysical disturbance. This definition does not exclude indigenous peoples and local communities who live in wilderness areas, depending on them for subsistence, and who have developed deep bio-cultural connections. Wilderness areas are important for biodiversity conservation, along with sustaining key ecological processes, and ecosystem services that underpin planetary life-support systems...

Most species are imperfectly detected during biological surveys, creating uncertainty around their abundance or presence at a given location. Decision-makers managing threatened or pest species are regularly faced with this uncertainty, and there are a growing number of examples of managers dealing with imperfect detection. Wildlife diseases have the potential to drive species to extinction, and as such managing species with disease is an important part of conservation. Devil Facial Tumour Disease (DFTD) is one such disease that led to the listing of the Tasmanian devil (Sarcophilus harrisii) as endangered...

While marine protected areas (MPAs) can simultaneously contribute to biodiversity conservation and fisheries management, the global network is biased towards particular ecosystem types, as it was largely established in an ad hoc fashion. The optimization of trade-offs between biodiversity benefits and socio-economic values increases implementation success and minimizes enforcement costs in the long run, but is often neglected in marine spatial planning (MSP). Although the acquisition of spatially explicit socioeconomic data is often perceived as a costly/secondary step in MSP, it is critical to account for lost opportunities by people whose activities will be restricted, especially fishers...

Abundance estimates are essential for estimating the viability of populations and the risks posed by alternative management actions. An effort to estimate abundance via a repeated mark-recapture experiment may fail to recapture marked individuals. We present a framework for obtaining lower bounds on abundance in the absence of recaptures for both panmictic and spatially-structured populations. We applied this nil-recapture method to data from a 12-year survey of pallid sturgeon (Scaphirhynchus albus) in the lower and middle Mississippi River; none of the 241 individuals marked were recaptured in the survey...

To contribute to the aspirations of recent international biodiversity conventions, protected areas (PAs) must be strategically located, and not simply established on economically marginal lands as they have in the past. With refined international commitments under the Convention of Biodiversity to target protected areas in places of 'importance to biodiversity', this may now be the case. Here we analyze location biases in PAs globally over both historic (pre-2004) and recent time periods. Discouragingly, we find that both old and new protected areas are not targeting places with high concentration of threatened vertebrate species...

Understanding the environmental contributors to population structure is of paramount importance for conservation in urbanized environments. We used spatially-explicit models to determine genetic population structure under current and future environmental conditions across a highly fragmented, human-dominated environment in Southern California to assess the effects of natural ecological variation and urbanization. We focused on seven common species with diverse habitat requirements, home range sizes, and dispersal abilities...

Growing resource demands by humans, invasive species, natural hazards, and a changing climate are creating broad-scale impacts and have created the need for broader-extent conservation activities that span ownerships and even political borders. Implementing regional-scale conservation brings great challenges, and learning how to overcome these challenges is essential for maintaining biodiversity (i.e., richness and evenness of biological communities) and ecosystem functions and services across scales and borders in the face of system change...

Establishing protected areas has long been an effective conservation strategy, and is often based on more readily surveyed species. The potential of any freshwater taxa to be a surrogate of other aquatic groups has not been fully explored. We compiled occurrence data on 72 species of freshwater fish, amphibians, mussels, and aquatic reptiles for the Great Plains, Wyoming. We used hierarchical Bayesian multi-species mixture models and MaxEnt models to describe species distributions, and program Zonation to identify conservation priority areas for each aquatic group...

There is global concern about tropical forest degradation, in part, because of the associated loss of biodiversity. Communities and indigenous people play a fundamental role in tropical forest management and they are often efficient at preventing forest degradation. However, monitoring changes in biodiversity due to degradation, especially at a scale appropriate to local tropical forest management, is marred with difficulties including the need for expert training, inconsistency across observers, and the lack of baseline or reference data...
