Abstract(s)
JUSTIFICATION: Polydesmus ribeiraensis is endemic to São Miguel (Azores, Portugal). It has a very small Extent of Occurrence (EOO = 16 km²) and Area of Occupancy (AOO = 16 km²). There is a continuing decline in the EOO, AOO, extent and quality of habitat as well as the number of mature individuals as a result of the invasions of non-native plants and displacement by exotic millipedes. Increasing tourism in the island might also impact its habitat, being a scenic destination. The species occurs only at one location, and so it is assessed as Critically Endangered (CR). We suggest as future measures of conservation: (1) regular monitoring of the species; (2) control of invasive species namely Hedychium gardnerianum, and (3) measures to mitigate possible impacts from increasing tourism.
