Managing rock outcrops to improve biodiversity conservation in Australian agricultural landscapes

Summary  Rocky outcrops are prominent geological features in agricultural landscapes worldwide. Reptiles are a major component of these habitats and some species are restricted to, and more abundant on, rocky outcrops than in remnant vegetation. Rock outcrops are important to reptiles because they provide resources that are often limited in the surrounding landscape (e.g. micro-gradients in climatic conditions, basking- and retreat-sites). However, there is a knowledge gap in the literature addressing the conservation value of small, rocky outcrops. Management may be necessary to reverse habitat degradation in these systems. We identify four key areas of management that need to be addressed to improve outcrop habitat values and enhance biodiversity conservation in agricultural landscapes. Specific actions involve: (i) protecting outcrops from processes that cause damage to rock microhabitat, (ii) monitoring and managing changes in vegetation structure to maintain thermally suitable environments, (iii) applying integrated pest animal control and (iv) improving matrix management to enhance inselberg function and landscape connectivity. Further research is required to evaluate the efficacy of different management regimes on outcrop biota. We hope this paper will provide the stimulus for land managers to incorporate rocky outcrops in future biodiversity conservation programmes.     

Convention on Biological Diversity: a review of national challenges and opportunities for implementation

The Convention on Biological Diversity (CBD) lies at the heart of biodiversity conservation initiatives. It offers opportunities to address global issues at the national level through locally grown solutions and measures. This article reviews the national challenges and opportunities in meeting requirements of the CBD by analysing twenty Third National Reports (TNRs), covering five different CBD regional clusters from the three global economic groups. While there is a plethora of challenges, the predominant ones discussed in this study include: institutional and capacity, knowledge and accessible information, economic policy and financial resources, cooperation and stakeholder involvement, and mainstreaming and integration of biodiversity. The underlying problem is that limited capacity in developing countries and transition economies undermines conservation initiatives. Lack of capacity in science, coordination, administration, legislation, and monitoring are barriers to on-ground implementation of biodiversity programmes. Opportunities to overcome these challenges embrace use of knowledge products, information-sharing mechanisms, participatory platforms, educational programmes, multi-level governance, and policy coherence. Innovative market-based instruments are also being trialled in various countries, which seek to offer incentives to local communities. The article concludes that conservation measures should be supported by multiple sectors and secure high level political support. Political, economical, and legislative sectors are more likely to show interest in CBD implementation and use it as a tool for managing biodiversity when they know the Convention processes and perceive it as a benefit. Modest investments in capacity building and training, and engaging different sectors in setting priorities would have a significant pay-off.     

Targeted control of widespread exotic species for biodiversity conservation: The Red Fox (Vulpes vulpes) in New South Wales, Australia

Summary   Widespread exotic species provide one of the greatest challenges to biodiversity conservation because they often have devastating impacts on native biota but are near impossible to eradicate. The Red Fox ( Vulpes vulpes ) is established across most of mainland Australia, where it has been linked to severe declines and extinctions of a broad suite of native fauna. A targeted approach to reducing the impacts of Foxes on biodiversity was instigated in New South Wales in 2001 under the New South Wales Fox Threat Abatement Plan. It is based on three simple steps. First, explicit priorities for Fox control are established by identifying which native species are at greatest risk from Fox predation and at which sites Fox control for these species is most critical. Second, high-frequency broad-area Fox-control programmes are established across all land tenures at these priority sites. Third, monitoring programmes are established to measure the response of targeted native fauna and Foxes to Fox control. Monitoring helps refine the priorities for control and the methods used over time. This approach provides a model for the strategic control of widespread exotic pests which threaten biodiversity.     

The business of biodiversity – What is needed for biodiversity markets to work

There has been considerable discussion in Australia about market-based initiatives with the potential to bring effective incentives and greater investment for farmers and other land managers to promote biodiversity conservation. These initiatives include biodiversity trading markets (also termed the nature repair market), stewardship schemes, certification programmes, sustainability frameworks, and natural capital accounting. We welcome these discussions and believe these initiatives would be true advances if they bring much greater investment in conservation and stronger protection and recovery of biodiversity. However, we also have major concerns about the integrity and scientific credibility of some of these initiatives. In this article, we discuss why it is critical that such initiatives both carefully define biodiversity and determine what elements of biodiversity are to be targeted in conservation efforts. We also discuss the fundamental importance of appropriate and agreed biodiversity metrics, as well as the critical need for rigorous, well designed and independent biodiversity monitoring. To ensure that initiatives like biodiversity trading markets, stewardship schemes, certification programmes, sustainability frameworks and natural capital accounting are rigorous, non-corruptible and actually deliver what they are intended to do, they will need to be underpinned by appropriate programme designs. This includes robust and transparent governance structures, high-quality monitoring and timely reporting of key metrics.     

Some issues and options for the conservation of native biodiversity in rural New Zealand

Summary For the 70% of New Zealand under private ownership, native biodiversity conservation has to occur within a landscape that must also provide a productive return to land owners. Recent New Zealand legislation, especially the Resource Management Act 1991, promotes sustainable management on private land by allowing for the economic and cultural well-being of local communities while providing for the protection of natural resources including native biodiversity. We suggest that, to effectively conserve native biodiversity in rural landscapes, we need to consider four key issues: (i) what might be realistic goals for native biodiversity conservation; (ii) how might we better arrange different land uses to meet both native biodiversity and production goals; (iii) what is the optimum arrangement of native biodiversity; and (iv) how native biodiversity conservation can improve productive returns to land managers. Options to enhance native biodiversity conservation include a variety of incentives (e.g. management agreements, financial incentives and regulatory systems) and onsite management options (e.g. remnant management, restoration plantings, weed and pest control, use of native species for commercial and amenity purposes, use of exotic species to facilitate native biodiversity). The importance of taking a landscape-based rather than a paddock-based approach to management is emphasized.     

Internet scientific name frequency as an indicator of cultural salience of biodiversity

Public interest in nature is an important driver of the success of conservation actions, such that increasing public awareness of biodiversity has become a major conservation goal (i.e. Aichi Target 1). Macro-scale monitoring of public interest towards nature has thus far been difficult, but the enormous quantity of information generated by the internet allows for new approaches using culturomic techniques. For example, other things being equal, we would expect that the vernacular (common) names of charismatic species with high levels of public interest (e.g. tiger, elephant) to appear on more web-pages than less ‘cultural’ species. Nevertheless, deriving metrics from such data is challenging because vernacular names often have multiple meanings (e.g. teal, jaguar) that could significantly bias culturomic metrics of cultural visibility. Scientific binomial names of species potentially avoid this problem because Latin is a ‘dead’ language and the scientific name typically applies only to the biological organism. Here, we investigate whether standard scientific names: i) are a robust proxy of web salience of vernacular species names, and; ii) have the same statistical relationship with vernacular species names across different cultural and language groups. Automated internet searches were carried out for scientific and vernacular names from a global bird species list and six national bird species lists (Australia, Brazil, Indonesia, Spain, Tanzania and USA). For national searches the results were restricted to country web domains. We found strong and consistent correlations between vernacular and scientific species names at both global and country level, independent of language and cultural differences. The universality of this relationship suggests that the web salience of scientific species names is a robust, cross-cultural indicator of species ‘culturalness’. Potential applications of this indicator include: i) the development of new indicators to assess public perceptions of biodiversity; ii) systematic identification of species with high cultural visibility; iii) empirical identification of the biogeographic, ecological, morphological and cultural characteristics of species that influence cultural visibility, globally and in different cultural settings, and; iv) near real-time monitoring of changes in species ‘culturalness’. The capture and processing of internet data is technically non-trivial, but can be replicated at low cost and has enormous potential for the creation of new macro-scale metrics of human-nature interactions.     

Monitoring for management of conservation and recreation in Australian protected areas

Protected areas are key to conservation of biodiversity, and Australia is one of the world’s megadiverse regions. Monitoring programs provide the information to assess the state of conservation resources, the severity of threats and the success of management responses. Here we compare the management priorities, monitoring priorities and actual monitoring practices of protected area management agencies in Australia, using four sets of data at continental scale and five at a more restricted regional scale. We track changes over a period of several years and focus at successively finer levels of detail. At both continental and regional scales, most management plans emphasise fire, invasive species and visitor management; and most monitoring programmes refer to visitor numbers and impacts as well as species and ecosystems. There is only a weak match, however, between reported management priorities and actual monitoring programmes; and the effectiveness of management responses is rarely monitored. The level of detail in visitor monitor programmes varies considerably: most parks count visitors, but few know what those visitors do. Threats from fire and invasive species receive more attention that those from recreation. At regional scale, the proportion of parks with defined monitoring programmes and priorities increased significantly from 2003/2004 to 2006/2007. Whilst only a proportion of protected areas monitor endangered species populations, for those that do this is the parameter reported in most detail, with many parks reporting single records of single individuals. Some parks also maintain anecdotal records of rare species outside routine monitoring programs.     

How to ensure threatened species monitoring leads to threatened species conservation

Monitoring is essential for effective conservation and management of threatened species and ecological communities. However, more often than not, threatened species monitoring is poorly implemented, meaning that conservation decisions are not informed by the best available knowledge. We outline challenges and provide best‐practice guidelines for threatened species monitoring, informed by the diverse perspectives of 26 conservation managers and scientists from a range of organisations with expertise across Australian species and ecosystems. Our collective expertise synthesised five key principles that aim to enhance the design, implementation and outcomes of threatened species monitoring. These principles are (i) integrate monitoring with management; (ii) design fit‐for‐purpose monitoring programs; (iii) engage people and organisations; (iv) ensure good data management; and (v) communicate the value of monitoring. We describe how to incorporate these principles into existing frameworks to improve current and future monitoring programs. Effective monitoring is essential to inform appropriate management and enable better conservation outcomes for our most vulnerable species and ecological communities.     

Institutions and incentives for biodiversity conservation

Incentive measures for biodiversity conservation cannot be evaluated and compared outside the context of institutional performance and relationships. The institutional framework for biodiversity incentives includes a variety of organizations operating on different spatial scales. The institutional actors with an impact on biodiversity include community groups, local and national governmental structures, NGOs, business enterprises and international organizations. But the positve influence of conservation-oriented organizations is often significantly outweighed by the negative influence of other sets of institutional actors who are largely unaware of biodiversity as a concept and not unduly concerned with its conservation. There are several options for improving the institutional framework for biodiversity incentives: (1) decentralization of resource management decision making to local levels; (2) engaging and reorienting government institutions; (3) establishing new national and international institutions; and (4) establishing functional linkages between key institutional actors. The role of local, national and international institutions in designing and implementing effective incentive measures for biodiversity conservation will be critical. But the dynamics within and between institutional actors influencing biodiversity conservation are complex, variable and insufficiently understood, somewhat like biodiversity itself.     

Managing ski resorts to improve biodiversity conservation: Australian reptiles as a case study

Alpine/subalpine environments are diverse systems that support many endemic species. Worldwide, these ecosystems are under threat from ski resort disturbances – even in areas broadly designated for biodiversity conservation. The effects of ski resorts on reptiles are largely unknown, making it difficult to implement effective conservation actions. Many ski resorts do not currently address the needs of reptiles, even those listed as threatened, in their management plans. If reptiles are to continue inhabiting ski resorts in Australia, strategies must be implemented that target their conservation. To begin to address this problem, we summarise current research investigating the effects of ski resorts on reptiles. Based on this information, we recommend strategies that will enhance the conservation of reptiles in areas affected by ski‐related disturbances. Suggested strategies include (i) restricting intensive disturbances to already highly modified areas of Australian ski resorts, (ii) avoiding disturbance of remaining native vegetation and structural complexity in ski resorts and (iii) re‐establishing structural complexity at highly modified sites through revegetation programmes, or through the cessation of mowing during peak reptile activity periods. While these strategies are designed to facilitate the persistence of reptiles in ski resorts, their long‐term success can only be evaluated by monitoring their effectiveness.     

Postgraduate Veterinary Training in Conservation Medicine: An Interdisciplinary Program at Murdoch University, Australia

Although many veterinarians in Australia have been interested in wildlife conservation, the concept of active and worthwhile involvement in biodiversity conservation has often seemed difficult to achieve. There are many boundaries which may hinder the ability of veterinarians to contribute effectively to wildlife conservation initiatives. This article discusses postgraduate veterinary educational initiatives at Murdoch University, Perth, Western Australia, which aim to train veterinarians to effectively participate in biodiversity conservation programs. The Master of Veterinary Studies (Conservation Medicine) and the Postgraduate Certificate in Veterinary Conservation Medicine have a flexible program structure and can be undertaken entirely by distance education. Their establishment required the removal of disciplinary, institutional, cultural, experiential, and professional development boundaries, which have traditionally impeded veterinary involvement in wildlife conservation projects. The programs have proven to be very successful and have attracted students across Australia and internationally. The strong commitment of Murdoch University to interdisciplinary study and distance education, the goodwill of staff from other divisions within the university, and enthusiastic support from collaborating institutions were critical for the development and establishment of the programs.     

Capacity of large-scale, long-term biodiversity monitoring programmes to detect trends in species prevalence

There is a critical need for monitoring programmes to assess change or trends in species status to inform conservation. A key aspect in developing such programmes is evaluating their statistical power—the ability to detect a real change. Here we examine the capacity of a broad-scale biodiversity monitoring programme in Alberta, Canada to measure changes in species prevalence. Using observed variation in detectability and prevalence for 252 species monitored at 85 sites, we simulated 3% annual declines and evaluated sample size (6 different sizes) and length of monitoring (5 different durations) necessary to detect change with a 90% certainty (power) at an α of 0.1. Our results suggest that after four monitoring cycles (e.g., 20 years for a 5-year cycle) a power of 90% can be expected for 99% of species when monitoring 1,625 sites, 65% of species for 300 sites, 27% of species for 75 sites, and 8% of species for 25 sites. We found that 66% detectability and 50% prevalence were needed to ensure that 3% annual change is detected at 50 sites over a 20-year period. Our results demonstrate that broad-scale monitoring programmes cannot effectively detect trends in all species at all spatial scales. The time period and spatial scale necessary to detect a real change at a specified level needs to be provided to stakeholders to ensure the short-term success of biodiversity monitoring programmes and to ensure that the most robust indicators of biodiversity are selected.     

The NSW Environmental Services Scheme: Results for the biodiversity benefits index, lessons learned, and the way forward

Summary   In 2002 the Environmental Services Scheme (ESS) was launched in New South Wales, Australia. Its aim was to pilot a process to provide financial incentives to landholders to undertake changes in land use or land management that improved the status of environmental services (e.g. provision of clean water, healthy soils, biodiversity conservation). To guide the direction of incentive funds, metrics were developed for use by departmental staff to score the benefits of land use or land management changes to a range of environmental services. The purpose of this paper is to (i) report on the development of one of these metrics – the biodiversity benefits index; (ii) present the data generated by field application of the metric to 20 properties contracted to the ESS; and (iii) discuss the lessons learned and recent developments of the metric that aim to make it accessible to a wider range of end-users and applications.     

Potentials for monitoring gene level biodiversity: using Sweden as an example

Programs for monitoring biological diversity over time are needed to detect changes that can constitute threats to biological resources. The convention on biological diversity regards effective monitoring as necessary to halt the ongoing erosion of biological variation, and such programs at the ecosystem and species levels are enforced in several countries. However, at the level of genetic biodiversity, little has been accomplished, and monitoring programs need to be developed. We define “conservation genetic monitoring” to imply the systematic, temporal study of genetic variation within particular species/populations with the aim to detect changes that indicate compromise or loss of such diversity. We also (i) identify basic starting points for conservation genetic monitoring, (ii) review the availability of such information using Sweden as an example, (iii) suggest categories of species for pilot monitoring programs, and (iv) identify some scientific and logistic issues that need to be addressed in the context of conservation genetic monitoring. We suggest that such programs are particularly warranted for species subject to large scale enhancement and harvest—operations that are known to potentially alter the genetic composition and reduce the variability of populations.     

Area prioritization for biodiversity conservation in Québec on the basis of species distributions: a preliminary analysis

Results are presented which prioritize areas for potential protection in Québec on the basis of biodiversity considerations. These results are relevant to the ongoing public discussion in Québec about designating new parks and refuges so that the province may fulfil its obligations to Canada's Endangered Spaces Campaign. The prioritization algorithm used in this analysis is based on rarity and complementarity. It attempts to sample biodiversity in as area-efficient a way as possible. The biodiversity surrogates used here comprise a subset of 743 species for which data on spatial distributions are publicly available; the analysis begins with 394 species at risk. It is shown that: (i) the existing network of protected areas in Québec does a poor job of protecting these biodiversity surrogates; (ii) adding adjacent areas to this network will not be the optimal way of protecting these biodiversity surrogates; (iii) many of the areas that have highest priority are in southern Québec, which has a high human population density; (iv) because of (iii), designating parks may not be economically or sociologically feasible and more adaptive alternative conservation plans will have to be devised; (v) coastal areas, riparian habitats, and other wetlands should have high priority for protection but are currently very inadequately represented in the reserve network; (vi) there is some reason for concern about the clear-cut logging of boreal forests in northern Québec; and (vii) the islands, Île d'Anticosti and the Îles-de-la-Madeleine, emerge as being of very significant conservation value and plans for the protection of areas on them should be an immediate goal for biodiversity conservation in Québec.     

Objectives versus realities: Spatial,temporal, financial and social deficiencies in Australia’s public revegetation investment model

Past and continuing fragmentation and modification of ecosystems, as well as other threatening processes, cause ongoing biodiversity losses and species extinctions in Australia. At the same time as biodiversity declines, government funding for conservation and restoration is diminishing, leading to reduced action and greater reliance on private investment and community groups. In order to maintain and restore biodiverse ecosystems and the essential services they provide, both conservation of existing vegetation and habitat reconstruction are required. In this paper, we summarise the available data on planting area and cost from the Australian Government’s 20 Million Trees programme (2014–2020), the largest recent national‐scale revegetation incentives programme in Australia. We find that the current spatial scale of effort and investment in habitat reconstruction is insufficient to match the scale required to meet national conservation objectives. Furthermore, the funding rate ($/ha) and contracting arrangements are inadequate for the establishment of high‐quality self‐sustaining vegetation needed for the recovery of Australia’s threatened species and ecological communities. We estimate that the minimum amount of funding required for habitat reconstruction is at least five times higher than is provided for current national flagship programmes such as 20 Million Trees. We provide recommendations, designed to assist future habitat reconstruction programmes achieve their long‐term biodiversity objectives.     

Addressing the threats to biodiversity from oil-palm agriculture

Oil-palm agriculture is the greatest immediate threat to biodiversity in Southeast Asia. Despite the efforts of environmentalists, oil palm continues to expand across the tropics. Those concerned about the impacts of oil palm on biodiversity must face some harsh social, economic, and ecological realities: (i) oil palm has been a very profitable crop; (ii) palm oil is used in so many products that simple, direct actions, such as boycotts, are unlikely to succeed; (iii) there is currently insufficient demand for certified sustainable palm oil and inadequate political clout from environmental groups in two of the biggest markets for palm oil—China and India—to slow the rate of forest conversion; and (iv) oil-palm agriculture has improved the lives of poor rural communities in Southeast Asia (although it has also disenfranchised some indigenous communities). To address the threats posed by oil-palm agriculture to biodiversity, environmentalists must change the behavior of the palm oil business through: (i) regulations to curb undesirable activities (e.g., a ban on converting forests to oil palm); (ii) financial incentives to promote desirable behavior (e.g., production of certified, sustainable oil palm); (iii) financial disincentives designed to discourage undesirable behavior (e.g., consumer pressure on major manufacturers and retailers to use palm oil that does not come from plantations created at the expense of forests); and (iv) the promotion of alternative, more biodiversity-friendly uses of forested land that might otherwise be converted to oil palm. There is no single best approach for dealing with the oil-palm crisis in Southeast Asia; a mixture of regulations, incentives, and disincentives targeted at all sectors of the oil-palm industry is necessary to protect the region’s rapidly disappearing forests.     

Funding begets biodiversity

Aim Effective conservation of biodiversity relies on an unbiased knowledge of its distribution. Conservation priority assessments are typically based on the levels of species richness, endemism and threat. Areas identified as important receive the majority of conservation investments, often facilitating further research that results in more species discoveries. Here, we test whether there is circularity between funding and perceived biodiversity, which may reinforce the conservation status of areas already perceived to be important while other areas with less initial funding may remain overlooked. Location Eastern Arc Mountains, Tanzania. Methods We analysed time series data (1980–2007) of funding (n = 134 projects) and plant species records (n = 75,631) from a newly compiled database. Perceived plant diversity, over three decades, is regressed against funding and environmental factors, and variances decomposed in partial regressions. Cross‐correlations are used to assess whether perceived biodiversity drives funding or vice versa. Results Funding explained 65% of variation in perceived biodiversity patterns – six times more variation than accounted for by 34 candidate environmental factors. Cross‐correlation analysis showed that funding is likely to be driving conservation priorities and not vice versa. It was also apparent that investment itself may trigger further investments as a result of reduced start‐up costs for new projects in areas where infrastructure already exists. It is therefore difficult to establish whether funding, perceived biodiversity, or both drive further funding. However, in all cases, the results suggest that regional assessments of biodiversity conservation importance may be biased by investment. Funding effects might also confound studies on mechanisms of species richness patterns. Main conclusions Continued biodiversity loss commands urgent conservation action even if our knowledge of its whereabouts is incomplete; however, by concentrating inventory funds in areas already perceived as important in terms of biodiversity and/or where start‐up costs are lower, we risk losing other areas of underestimated or unknown value.     

Review of the ecology of Australian urban fauna: A focus on spatially explicit processes

Abstract Cities have a major impact on Australian landscapes, especially in coastal regions, to the detriment of native biodiversity. Areas suitable for urban development often coincide with those areas that support high levels of species diversity and endemism. However, there is a paucity of reliable information available to guide urban conservation planning and management, especially regarding the trade‐off between investing in protecting and restoring habitat at the landscape level, and investing in programmes to maintain the condition of remnant vegetation at the local (site) level. We review the literature on Australian urban ecology, focusing on urban terrestrial and aquatic vertebrate and invertebrate fauna. We identify four main factors limiting our knowledge of urban fauna: (i) a lack of studies focusing at multiple ecological levels; (ii) a lack of multispecies studies; (iii) an almost total absence of long‐term (temporal) studies; and (iv) a need for stronger integration of research outcomes into urban conservation planning and management. We present a set of key principles for the development of a spatially explicit, long‐term approach to urban fauna research. This requires an understanding of the importance of local‐level habitat quality and condition relative to the composition, configuration and connectivity of habitats within the larger urban landscape. These principles will ultimately strengthen urban fauna management and conservation planning by enabling us to prioritize and allocate limited financial resources to maximize the conservation return.
