The Living Planet Index (trends in target and bycatch species) indicator is calculated using time-series data for vertebrate species. The underlying method is the same as for the global Living Planet Index (LPI) so the indicator uses data that is of high temporal resolution and spatially explicit through being tied to a particular location. This allows for recording of metadata on local threats and conservation action and allows for disaggregation at different scales. Being based on annual changes in species populations on site level measures, the index is sensitive to annual change and reflects environmental conditions and impacts. Data sources and methods are publicly accessible online (www.livingplanetindex.org) and traceable.

This indicator can be used to complement the existing indicators for target 6 by providing trends in populations of bycatch species. It can also show trends in target species that are not covered by the commercial stock data. This fills a gap for target 6 by providing a population level indicator for this target.
