The Forest Monitoring Network of Belize (FORMNET-B) is a systematized group of PSPs that was established in 1992, as a part of the Forest Planning and Management Project. Initially, only 30 PSPs were established under the FPMP, but in recent years, the Belize Forest Department revived the network under their Sustainable Forest Management Program where more establishments were made. FORMNET-B is an efficient standardized monitoring of Belize’s forests, where country-specific data on tree growth, mortality and the overall health of these forests are assessed. FORMNET-B plays a vital role in providing country-specific emission factors for the FREL and GHG inventory.
