Wetlands are important areas for biodiversity and climate control, but since 1970, around 35 percent of the world’s wetlands have been destroyed by factors such as climate change and urbanization. In order to better understand the value of wetlands, the goal of this study is to research and compare the biodiversity in salt marshes and upland areas at Randall’s Island. To accomplish this, we will collect samples of invertebrates because of their notable impact on biodiversity. The invertebrates will be collected from two 9m2 locations in each environment, making four total collection areas. We will then process the specimens’ DNA by isolating it through the Silica method and amplifying it through Polymerase Chain Reaction (PCR). The biodiversity between the areas will be compared by looking at the species abundance and the variation of species between wetlands and uplands. This comparison will give us insights into the ecosystem of Randall’s Island and how invertebrates affect e
