Numerous changes in the marsh and aquatic flora of East Harbor State Park have occurred since 1895. Of the 89 species collected and identified before 1900, 22 are no longer present. This represents a loss of approximately 25% of the species originally reported by Moseley (1899) and Pieters (1901). The species lost would rise to 42%, if those species formerly abundant, but now rare, or occurring as one or two small, isolated populations disappear. Probable causes for these changes are wind and water erosion, fluctuating water levels, dredging, establishment and spread of species new to the park, and increase or decrease in abundance of species already present.
