Carausius scotti
Overview
Carausius scotti, or Scott's stick insect, is an insect species endemic to Silhouette Island in the Seychelles. It was assessed as critically endangered in The IUCN Red List of Threatened Species in 2007 as a restricted range species with an area of occupancy of 10 square kilometres (3.9 sq mi) with an estimated extent of occurrence (EOO) of 18 square kilometres (6.9 sq mi). The species is primarily threatened with declining woodland habitats due to invasive plants and also climactic factors such as droughts.
It is present in the protected area of Silhouette National Park as a part of conservation efforts, however more conservation actions are needed, as well as further research to determine population sizes and trends.
Carausius scotti faces severe threats from habitat destruction due to deforestation and agricultural expansion in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and human disturbance. Climate change poses additional risks through altered precipitation patterns and temperature shifts that could affect the specific microhabitat conditions this stick insect requires.
Habitat
Carausius scotti inhabits tropical forest environments, likely requiring specific host plants and microclimate conditions typical of undisturbed forest ecosystems. The species appears to be adapted to particular vegetation types within its restricted geographic range.
