Distribution Analysis of Invasive Plant Species at the Kleinstuck Preserve
MetadataShow full item record
Rapid urban migration has significantly decreased the amount of urban green spaces (UGS) in cities and the surrounding area. Although declining, the presence of UGS provide many benefits to both humans and the environment. Notably, UGS support local and regional biodiversity and are able to support a wide range of endangered species. However, many factors such as habitat destruction, climate change, and invasive species threaten the biodiversity of UGS. Invasive species pose a significant threat to the native vegetation within cities and rapidly decline their populations. Costly to the environment and economy, research surrounding invasive species is important to understanding how best to manage their populations. This study exemplifies an efficient and effective way to map the distribution of invasive plant species in an urban preserve using GIS. Furthermore, this study identifies anthropogenic and abiotic influences upon the presence of invasive plant species in order to effectively mitigate further introduction. The spatial distribution of eight invasive plant species were analyzed including species like bittersweet and garlic mustard. The logistic regression model show many of the factors such as distance from the trail, distance from the boundary, and elevation to be predictive of the presence of individual species. Furthermore, this study suggests human activity as well as natural conditions of the preserve influences the distribution of invasive plant species and provides insight to future management strategies.
