Abstract
Recognizing the imperiled status of biodiversity and its benefit to human well-being, the world's governments committed in 2010 to take effective and urgent action to halt biodiversity loss through the Convention on Biological Diversity's "Aichi Targets". These targets, and many conservation programs, require monitoring to assess progress toward specific goals. However, comprehensive and easily understood information on biodiversity trends at appropriate spatial scales is often not available to the policy makers, managers, and scientists who require it. We surveyed conservation stakeholders in three geographically diverse regions of critical biodiversity concern (the Tropical Andes, the African Great Lakes, and the Greater Mekong) and found high demand for biodiversity indicator information but uneven availability. To begin to address this need, we present a biodiversity "dashboard"--a visualization of biodiversity indicators designed to enable tracking of biodiversity and conservation performance data in a clear, user-friendly format. This builds on previous, more conceptual, indicator work to create an operationalized online interface communicating multiple indicators at multiple spatial scales. We structured this dashboard around the Pressure-State-Response-Benefit framework, selecting four indicators to measure pressure on biodiversity (deforestation rate), state of species (Red List Index), conservation response (protection of key biodiversity areas), and benefits to human populations (freshwater provision). Disaggregating global data, we present dashboard maps and graphics for the three regions surveyed and their component countries. These visualizations provide charts showing regional and national trends and lay the foundation for a web-enabled, interactive biodiversity indicators dashboard. This new tool can help track progress toward the Aichi Targets, support national monitoring and reporting, and inform outcome-based policy-making for the protection of natural resources.Entities:

Biodiversity indicators summary and data sources.
| Framework Component | Pressure/Driver | State | Response | Benefit (Impact) |
| Indicator | Forest coverage and rate of gross forest cover loss | Red List Index | Protected area coverage in key biodiversity areas | Quality-weighted freshwater provision from natural ecosystems to downstream human population |
| Aichi Target | Target 5: Loss of habitats is at least halved by 2020 | Target 12: Extinctions of known threatened species has been prevented by 2020 | Target 11: At least 17% of terrestrial…areas, especially important areas for biodiversity and ecosystem services are conserved by 2020 | Target 14: Ecosystems that provide essential services are restored and safeguarded by 2020 |
| What does it show | Spatial data represents the percent of forest cover for each 18.5 km pixel in 2000 and percent gross forest cover loss (i.e., deforestation) from 2000 to2005. Tabular FAO data summarize forest land use coverage and "net forest cover change" by country in 2005 and 2010. | An index of aggregate survival probability of species that occur in the given spatial unit. Values range from 1 (all species Least Concern) to 0 (all Extinct). | Mean percent area of key biodiversity areas covered by protected areas | Quality-weighted delivery of clean freshwater from natural habitats to downstream human populations per unit area |
| Data Source | Forest cover for year 2000 and gross forest cover loss 2000–2005 through Global Forest Monitoring Project | IUCN Red List assessment for: | - World Database on Protected Areas (UNEP-WCMC) (2010) | - World WaterGAP 2 model runoff map |
| - Hydrological drainage direction | ||||
| - Amphibians (1980, 2004) | - Global KBAs as represented by Important Bird and Biodiversity Areas (IBAs) and Alliance for Zero Extinction (AZE) sites | |||
| - Landscan Global Population Database | ||||
| - Birds (1988, 2008) | ||||
| - GlobCover land cover | ||||
| - Mammals (1996, 2008) | ||||
| Time frame | 2000–2005 | 1980–2008 | 1950–2010 | 2010 |
| Limitation and caveat | - Resolution is too coarse (18.5 km) to detect deforestation in small areas. | - Differing assessment dates requires interpolation and extrapolation to estimate aggregate trends | - The WDPA omit recently decreed protected areas | - Values are relative, not absolute |
| - The gross forest cover loss data shows deforestation only, not taking account afforestation | - Because of the heterogeneous distribution of species, regional extinction risk can skew national indicator values | - The WDPA does not currently document management effectiveness | - Only baseline (2010) data currently available; not able to estimate trend | |
| - Forest degradation was not quantified | - The proportion of a species' range within a given analysis unit is not considered | - Key biodiversity areas for taxa other than birds that are not endemic to single sites have only been identified in some countries | - Spatial resolution is too coarse (2,5921km2 pixels) to estimate freshwater provision in small areas | |
| - Red List categories are necessarily broad classes of extinction risk, so the RLI is moderately sensitive |
