Resumo(s)
Cheiracanthium floresense is a single-island endemic species restricted to Flores island in Azores, Portugal (Borges et al. 2010). It has a small Extent of Occurrence (EOO = 20-56 km²) and Area of Occupancy (AOO = 20-56 km²). The species is rare and only known from two subpopulations, at Natural Forest Reserves of Caldeiras Funda e Rasa and Morro Alto e Pico da Sé. The surrounding area is highly invaded by alien plants, and in the past, the species has probably strongly declined due to changes in habitat size and quality. Currently, invasive plants Hydrangea macrophylla, Hedychium gardnerianum and Rubus ulmifolius are changing some of the areas of the species' range and decreasing the quality of the habitat. Based on Ferreira et al. (2016) the habitat will further decline as a consequence of climate change. Based upon the small EOO of the species and continuing decline of its habitat area and quality, it is assessed as Critically Endangered. Therefore, we suggest as future measures of conservation: (1) regular monitoring of the species; and (2) control of invasive species namely Hedychium gardnerianum.
