Brief synthesisThe lush Lenggong Valley on the Malay Peninsula contains evidence in open-air and cave sites along the Perak River spanning all the periods of hominid history outside Africa from 1.83 million to 1,700 years ago. IntegrityThe Lenggong Valley has provided a fertile and environmentally stable habitat for repeated human occupation since early Palaeolithic times. The recent (post 1987) Lenggong Valley research relating to the story of early human migration ensures the reliability and authenticity of the property. Protection and management requirementsAll designated sites within the property are expected to be registered under the National Heritage Act 2005 and gazetted by 2012. The Property Management Plan for the Archaeological Heritage of the Lenggong Valley needs to be completed, approved by all parties concerned and then the Plan will set out objectives including the development of tourism and visitor management strategies, risk management strategies and provision for stakeholder participation and collaboration.
