Preparation of PBR is mandated under the Biological Diversity Act, 2002 and is the responsibility of BMCs. It is a register that contains comprehensive information on availability and knowledge of local biological resource (flora and fauna), their medicinal or any other use and any other TK associated with them. The current PBR preparation methodology being considered for widespread official use, has been developed by the NBA. This elaborates and presets a set of formats with tables and kind of information required that needs to be filled by BMCs with the help of students, researchers and knowledgeable individuals and be validated by BMC with the help of TSG/SBB as needed. This information will be kept in the safe custody of BMC. PBR is a legal document for purposes of determining Access and Benefit Sharing provisions under the Act.
