    • Mangrove Species Dominance Map of Pohnpei, Federated States of Micronesia as Modeled by a K-Nearest Neighbor (KNN) Model

    Metadata Updated: November 20, 2025

    Mangrove species dominance on Pohnpei island, Federated States of Micronesia was modeled with two geospatial model types: k-nearest neighbor (KNN) and random forest (RF) and a common set of predictors. Dominant mangroves were defined as species comprising the largest basal area per field plot. The KNN model produced one map, which shows all species' dominance locations in one raster layer. The KNN model results were the best based on field data and in field knowledge of the area. The KNN RStudio model and resulting map are shared here.
