An inventory of biodiversity data sources for conservation monitoring

share and publicise data sources and make existing tools and data freely available for the man- agers who most need them, we might be able to mainstream biodiversity data into decision- making and ultimately stop biodiversity loss. Supporting information S1 Table. Global biodiversity data sources of potential value in monitoring biodiversity state. Those data sources where at least some data (or mapping of data) appear to be instantly, freely and openly available are flagged with a star (�). Those data source on priority sites (AZE sites, G200 ecoregions, KBAs, etc) will usually need to be used in tandem with other data sources to be relevant to monitoring certain indicators (e.g. number/abundance of threatened species in priority areas). Note that some data sources would need updating before they could be of use. An updated list, with additional information, will be posted on https://www. speciesmonitoring.org/data-sources.html. Data source managers are encouraged to send any additional information or updates to SpeciesMonitoringSG@gmail.com. (DOCX) S2 Table. Global data sources of potential value in monitoring pressures and threats to biodiversity. Those data sources where at least some data (or mapping of data) appear to be instantly, freely and openly available are flagged with a star (�). Note that some data sources would need updating before they could be of use. An updated list, with additional information, will be posted on https://www.speciesmonitoring.org/data-sources.html. Data source managers are

Global data sources of potential value in monitoring conservation responses to biodiversity loss. Those data sources where at least some data appear to be freely and openly available are flagged with a star (�). Note that some data sources would need updating before they could be of use. An updated list, with additional information, will be posted on https:// www.speciesmonitoring.org/data-sources.html. Data source managers are encouraged to send any additional information or updates to SpeciesMonitoringSG@gmail.com. (DOCX) S4 Table. Global data sources with multiple uses for biodiversity monitoring. Those data sources where at least some data seem to be freely and openly available are flagged with a star (�). Note that some data sources would need updating before they could be of use. An updated list, with additional information, will be posted on https://www.speciesmonitoring.org/data- sources.html.
