The majority of land within Great Parks of Hamilton County (GPHC), Ohio, USA, is managed as natural area; and while threats to preservation are growing more numerous, resources to manage these natural areas are limited. We develop a quick method for GPHC staff to prioritize the natural areas in GPHC parks through the use of GIS tools and existing data. This study applies the scoring approach, which evaluates candidate sites individually using scores for multiple factors and then selects priority sites from the top of a ranked list. Three sets of multiple factors are used to compute the prioritization index, and they generate similar priority index maps. This method will help GPHC staff to make a better plan for habitat restoration activities in their parks.
A non-native invasive shrub, named Amur honeysuckle, has caused various problems to the habitats of native plants and animals. Local governments, private landowners and non-profit groups spend numerous efforts on removing these species from forests. The first step to remove the species is to know their spatial distribution. The major objective of this study is to explore how to quickly map honeysuckle distribution by using high resolution satellite images. The case study is located in Great Parks of Hamilton County (GPHC), Ohio. A World-View2 satellite image acquired on Nov. 9th 2013 was classified into several land use types, including low density honeysuckle area, medium/high density honeysuckle area, grass/crop, bare soil/construction, and water/wet land. Half of the field data that we collected in Nov. 2013 and some high resolution aerial photos (with 4 inch spatial resolution) were used to validate the classification result. The study result demonstrates that the World-View2 image delineates honeysuckle distribution fairly well, in particular, for medium/high density honeysuckle areas. As a pilot program utilizing advanced geospatial analysis, this project will provide important information for understanding the status of wildlife habitats and for implementing site-specific management in parks and nature preserves.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
