Population [top]

Population:Twenty three animals were recorded at 15 new sites between 2002 and 2014, indicating that the species may not be as rare as previously thought (Faustino de Lima et al. 2016).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Crocidura thomensis is associated with a variety of habitats from old-growth tropical moist forest to lowland plantations (Faustino de Lima et al. 2016).
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): Introduced species, the use of pesticides, and agricultural intensification have all been identified as threats to the survival of this shrew and provide reasonable causality for its decline in the agricultural matrix (Faustino de Lima et al. 2016).

Conservation Actions [top]

Conservation Actions: There are no direct conservation measures in place for this species. The species is found in the São Tomé Obô Natural Park, which protects the island’s main forest block (Faustino de Lima et al. 2016). There is a need to conserve areas of suitable forest habitat for this species. Additional studies are needed into the distribution, abundance, general ecology and threats to this little-known species.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
