Hyperspectral Reflectance Data for Flowers, Fruits, Bark, and Leaves of Plants on Barro Colorado Island, Panama

This dataset contains hyperspectral reflectance measured on flowers, fruits, bark, seeds, and conspicuous leaves of plants collected on Barro Colorado Island (BCI), Panama. Samples were collected mostly from fallen material on the forest floor or from understory plants, were placed in individual zipper storage bags in a cooler with ice for transport back to the lab, where hyperspectral reflectance was measured using an ASD FieldSpec 4 Standard Resolution spectrometer. This version release contains data for samples collected between 2024/03/28 and 2026/03/05, and encompasses a total of 866 samples of 207 species across 24 orders and 55 families. This includes 380 flower samples of 116 species, 325 fruit samples of 123 species, 112 leaf samples of 43 species, 34 bark samples of 30 species, and 16 seed samples of 11 species. The goal of this project is to contribute to the basis for automated species identification of woody plants in diverse tropical forests using hyperspectral imaging.
