Island biotas are threatened by habitat loss, anthropogenic pollution and climate change, as well as the effects of introduced species. The Azorean Biodiversity Group conducts several projects to assess the impact of these threats on the invertebrate communities in the Azorean archipelago. Most of the projects focus on the fauna of the remnants of the native humid forests. These forests once covered almost the entire surface of the islands but nowadays they only can be found at high elevations and steep slopes to where people rarely venture. Although they have been protected by law for several years, many introduced species that became invasive negatively affect native communities and climate change is also likely to have an adverse impact.
