Approximately 550 elephants out of the 1700 elephants in Sumatra are located in Aceh, northern Sumatra in fragmented habitat. In order to protect this segment of the elephant population, there are 7 CRUs working in partnership with government conservation agencies. Utilizing captive elephants, their mahouts, and local community representatives for direct, successful field-based conservation interventions, these units support the conservation of wild elephants and protection of habitat, and create opportunities for local communities achieving positive outcomes for both elephants and people. Continuing the activities conducted by the CRU units is important for sustainable management, for mitigation of HEC, and to support local community awareness and involvement in forest protection. IEF is supporting their operation and continuing patrol activities as well as capacity building efforts.
