Avian Reintroduction & Translocation

Summary Charts

These charts present various characteristics of the reintroduction programs entered in the database; the charts are updated as data are added or edited in the database. For example in Chart A, an ARTD user can observe whether the species that are reintroduced are more likely to be listed as one category than another in the IUCN Red List, the conservation community's accepted standard. The user can draw their conclusions from the data but on the website, we do not interpret the data to conclude why one category may be greater than another. The data are dynamic and depend on the species, sites, source population and release events that are entered in the database.

The sample sizes (N) vary between charts depending on the subsets of data that are included in the analyses and the frequency of values that are unknown (see The Data page) for the relevant variable.
