Identification of hydrophytes will improve the delineation and classification of wetlands on remotely sensed imagery. Spectral reflectance measurements of 10 species of hydrophytes were made with an Exotach radiometer during three phenological stages, flowering and early seed, senescence, and early emergent. Reflectance data were analyzed to determine significant (≥.95) reflectance differences between species in each of four spectral regions during each phenological stage. Eight species had significantly (≥.95) different reflectances during the flower and early seed stage. Only one species could not be spectrally separated during at least one phenological stage. The results indicate that films sensitive to both visible and infrared spectra (e.g. ektachrome infrared) should provide best results for recognizing different species of hydrophytes.
