In 2004, WWF-India introduced the concept of Community Conserved Areas (CCAs) by issuing a declaration of the first CCA covering an area of 312 sq km in Thembang village of West Kameng district. A CCA Management Committee comprising local villagers responsible for the conservation of natural resources as well as socio-economic development of the village was also set up. Encouraged by the success of this model, the area under the Thembang CCA was increased to 635 sq km in 2012. Till date, the team has formed four CCAs covering an area of approximately 635 sq km in West Kameng and approximately 215 sq km in Tawang districts of the state.
