These requirements and practical guidance were developed by SPKS (Serikat Petani Kelapa Sawit - Oil
Palm Farmers Union) in collaboration with the HCSA (High Carbon Stock Approach) Secretariat, the
SHWG (Smallholder Working Group), and the HCSA Executive Committee.
The Oil Palm Farmers’ Union (SPKS, Serikat Petani Kelapa Sawit) carried out field tests of draft versions
in West Kalimantan, Indonesia in 2019, 2021 and 2022.
The High Conservation Value Network (HCVN) supported its development as part of the HCSA SHWG
and provided recommendations for the development of proxies and adaptations of High Conservation
Value (HCV) categories for a smallholder context.
The HCSA Secretariat thanks all concerned for their valuable contributions.
