description Sumba deciduous forests Overview
The Sumba deciduous forests are a terrestrial ecoregion located on Sumba Island in the Lesser Sunda Islands of Indonesia. Characterized by a tropical climate with a pronounced dry season, the vegetation consists primarily of deciduous trees, scrublands, and patches of grassland. The isolated nature of the island has resulted in a high degree of endemism, making the forests a critical habitat for restricted-range bird species such as the Sumba hornbill and the Sumba green pigeon. The ecoregion faces ongoing threats from agricultural expansion, logging, and human-induced fires.
