By assigning the mean AGC stock per species per area to the map, carbon stock distributions were visualized spatially, allowing future conservation efforts to be directed to carbon dense stands.Ĭitation: Woltz VL, Peneva-Reed EI, Zhu Z, Bullock EL, MacKenzie RA, Apwong M, et al. In 2018, Pohnpei mangroves contained over 1.07 million MgC in AGC pools. Mean AGC was 167 ± 11 MgC ha -1, which is greater than the global average of mangroves (115 ± 7 MgC ha -1) but within their global range (37–255 MgC ha -1) Kauffman et al. The k-nearest neighbor model performed better than random forest models to map species dominance in these forests. A gridded or wall to wall approach is suggested when possible for defining carbon stocks of a large area due to high variability seen in our data. Forest structure and aboveground carbon (AGC) stocks were inventoried using a systematic sampling of field survey plots and extrapolated to the island using k-nearest neighbor and random forest species models. Change analysis indicated a slight (0.76%) increase of mangrove area between 19, contrasting with global mangrove area declines. In 2018, the island had 6,426 ha of mangrove forest. ![]() As part of a multi-component assessment to evaluate vulnerabilities of mangrove forests on Pohnpei, mangrove forests were mapped at two points in time: 19. ![]() Mangrove forests are the most important ecosystems on Pohnpei Island, Federated States of Micronesia, as the island communities of the central Pacific rely on the forests for many essential services including protection from sea-level rise that is occurring at a greater pace than the global average. ![]()
