Impacts of the non-native aquatic plant water chestnut, Trapa natans, on inland freshwater nitrogen and oxygen dynamics, and host-specificity testing of the biological control insect, Galerucella birmanica
Water chestnut, Trapa natans, is a non-native aquatic plant with floating rosettes of leaves that has established and continues to spread in northeastern North America. Growing in calm freshwater environments, T. natans can grow densely on water surfaces, transforming open waters into thick …

Tidal Wetland Inundation and Vegetation Phenology from Space: A Synthesis of Approaches for Characterizing Ecological Status and Inundation Dynamics in Tidal Wetlands with Remote Sensing Observations
… to map invasive aquatic water chestnut (<em>Trapa natans</em>) with greater than 96% accuracy. This decision tree approach utilized multitemporal Sentinel-1 C-band SAR imagery. The same decision tree classification was utilized to map non-persistent emergent vegetation, an indicator of tidal …
