These factsheets are based on the guidelines of the Biodiversity Indicators Partnership (Biodiversity Indicators Partnership, 2011), with the addition of explicit sections on how to define the confidence interval for each metric, the properties of the indicators. These indicators are used as part of the report series "The status of biological invasions and their management in South Africa" For the latest version of the report see http://dx.doi.org/10.5281/zenodo.7414803 for general details see http://iasreport.sanbi.org.za Much of the information on how the indicators are scored and how confidence levels are calculated are inherited from the metadata to the list of alien taxa for South Africa https://doi.org/10.5281/zenodo.7433112 or from workflows associated with the national status report on biological invasions https://doi.org/10.5281/zenodo.7433129 There are several additional facilitating mechanisms that are vital for successful interventions, specifically: accessibility of data and information; research; organisational, infrastructure, and human capacity; and public awareness and engagement. Indicators for these are not included as they are not used for measuring outcomes or outputs of the interventions themselves.
