ABSTRACT In 2002, world leaders committed, through the Convention on Biological Diversity, to achieve a significant reduction in the
rate of biodiversity loss by 2010. We compiled 31 indicators to report on progress toward this target. Most indicators of
the state of biodiversity (covering species’ population trends, extinction risk, habitat extent and condition, and community
composition) showed declines, with no significant recent reductions in rate, whereas indicators of pressures on biodiversity
(including resource consumption, invasive alien species, nitrogen pollution, overexploitation, and climate change impacts)
showed increases. Despite some local successes and increasing responses (including extent and biodiversity coverage of protected
areas, sustainable forest management, policy responses to invasive alien species, and biodiversity-related aid), the rate
of biodiversity loss does not appear to be slowing.

    • "They can provide reliable and cost-effective means of tracking environmental changes that are otherwise difficult to measure directly (Fleishman and Murphy, 2009), as well as for reporting on progress of policy and conservation interventions. For example, biodiversity indicators were widely used to test the progress towards the target of reducing the rate of biodiversity loss by 2010, set at the 2002 World Summit of Sustainable Development and eventually to conclude that the target had not been met at the global level (Butchart et al., 2010; Secretariat of the Convention on Biological Diversity, 2010).

    ABSTRACT: Multi-species indicators are often used to assess biodiversity trends. By combining population trends across several species they summarise trends across a community. Composite indicators such as these are useful for examining general temporal patterns and may suggest important drivers of biodiversity change. However, they may also mask substantial spatial variation in population trends, particularly when they are calculated over large spatial regions. We produced spatially-explicit indicators for farmland and woodland bird communities in the UK and further separate these into trends for generalist and specialist species within each group. We found considerable spatial variation in the indicators, which is masked by indicators calculated at the national level. The farmland community indicator showed mostly positive trends in western areas and extensive declines in south-east England. The woodland community indicator showed a north–south divide, with increases in Scotland and northern England and stability in the southern regions. For both communities, indicator trends for specialist species were more negative than those for generalists. We found no significant difference in farmland community indicators between arable land and improved grassland. Woodland specialists had significantly more negative trends in broadleaf compared to coniferous woodlands, suggesting habitat-type is one of the drivers of changes in the woodland community. These spatial patterns in bird population trends may be used to highlight regional conservation priorities and identify where those may differ from the national scale. In combination with information about other environmental changes, they may also be used to develop hypotheses about potential drivers of change. We advocate that this approach is adopted for other taxa and geographical areas.

    ABSTRACT: Ecological signs of Earth's biosphere forewarn an alarming trajectory towards a global mass-extinction. Assessing species performance and susceptibilities to decline is essential to comprehend and reverse this trend. Yet it is challenging, given difficulties associated with quantifying individual and population processes that are variable across time, space, and life-stages. We describe a new approach to estimating and comparing species performances that combines empirical data, a novel theoretical consideration of population dynamics, and modern statistics. Our approach allows for a more realistic continuous representation of individual performances along development stages while taking into account non-linearity, and natural variability as captured by spatio-temporally replicated observations. We illustrate its application in a coral meta-assemblage composed of populations of the three major reef-building taxa Acropora, Pocillopora, Porites. Using a unique set of highly replicated observations of individual coral dynamics under various environmental conditions, we show how taxa differ in their investment in recruitment and size-specific aptitude for growth and survival, notably through different use of clonal shrinkage, fragmentation, fission, and fusion processes. Our results reveal contrasting life-history trade-offs among taxa which, along with differing patterns of density-dependent recruitment, modulate species responses to decline. These differences in coral life history traits reflect opposing life-strategies, imply regulation at differing life-stages, and explain divergence in species trajectories. Our findings indicate a high potential for resilience in Pocillopora and Porites populations, thanks respectively to a sustained recruitment that promotes demographic elasticity through replacement of individuals, and a steady resistance to mortality which confers persistence through lingering of individuals. Resilience in Acropora appears more arbitrary, given high susceptibility to perturbations and dependency of recruitment on presence of established local populations. We identify management actions that can complement Acropora's life history and benefit recovery of its populations following mortality events. Our regression-modelling approach to quantifying and comparing species performances in different population processes is applicable to all taxa, as illustrated even those with complex clonal life histories, and can be implemented at wide spatio-temporal and taxonomic coverage. It can promote more accurate representation of species dynamics in both descriptive and predictive modelling approaches. The semi-parametric contrast curve method we develop facilitates comparing response variables along continuous explicative metrics while accounting for multiple sources of complexity in empirical data. It should widely benefit investigations in ecology and quantitative science.

    • "Despite an urgent need to develop mechanisms to promote biodiversity conservation (Ehrlich & Pringle, 2008; Butchart et al., 2010; Bayon & Jenkins, 2010; Estes et al., 2011), developing such mechanisms in human-dominated landscapes, where private ownership prevails and the cost of land purchase and opportunity costs of conservation can be substantial, is challenging (Naidoo et al., 2006; Wunder, 2007). One potentially cost-effective route to conservation in such areas may be to promote private land conservation easements or covenants that prohibit land use changes likely to reduce conservation values in exchange for monetary or other compensation (Merenlender et al., 2004; Knight et al., 2011).

    ABSTRACT: Conservation initiatives to protect and restore valued species communities in human-dominated landscapes face challenges linked to their potential costs. Conservation easements on private land may represent a cost-effective alternative to land purchase, but long-term costs to monitor and enforce easements, or defend legal challenges, remain uncertain. We explored the cost-effectiveness of conservation easements, defined here as the fraction of the high-biodiversity landscape potentially protected via investment in easements versus land purchase. We show that easement violation and dispute rates substantially affect the estimated long-term cost-effectiveness of an easement versus land purchase strategy. Our results suggest that conservation easements can outperform land purchase as a strategy to protect biodiversity as long as the rate of disputes and legal challenges is low, pointing to a critical need for monitoring data to reduce costs and maximize the value of conservation investments.
