    dct:description "Cattail (Typha) is a common plant found throughout the Prairie Pothole Region (PPR) of the United State. Typha x glauca, a hybrid between Typha latifolia and Typha angustifolia, is considered an invasive species that has spread across the PPR, negatively impacting the regions important wetlands and other aquatic habitats. The distribution of the various cattail taxa, however, is not well understood in the PPR. This data release reports genetic and morphologic data from a study intended to assess the distribution of the invasive hybrid cattail. Genetic-based taxonomic data (cattail taxa) are provided from nearly 500 cattail tissue samples collected from over 80 PPR wetlands." ;
