Development And Assessment Of A Spatial Decision Support System For Conservation Planning, Sean Murphy
Development And Assessment Of A Spatial Decision Support System For Conservation Planning, Sean Murphy
Electronic Theses and Dissertations
Land conservation is frequently cited as the most effective means of limiting the detrimental effects of anthropogenic forces on natural resources. Because governmental entities can be hampered by fiscal and political concerns, land trusts are increasing relied on to protect habitat. However, these groups often lack the analysis and research tools necessary to meet their mission. Geographic Information System (GIs) technologies such as Spatial Decision Support Systems (SDSS) offer the promise of allowing decision makers to explore their decision space at a landscape level of analysis.

Representational Analyses Of Conservation Lands In Maine, Stephanie Orndorff
Electronic Theses and Dissertations
The three studies reported here (i.e., statewide, southern Maine, and state and federal wildlife areas) identify what areas should be conserved to represent the natural diversity of Maine. Geographic Information System (GIs) technology was used to conduct the analyses comparing the distribution of abiotic and biotic variables representing natural diversity on and off conservation lands. In the statewide analysis, 10 environmental variables were compared on and off conservation lands using ArcGrid with a cell resolution of 1.86 x 1.86 km. The areas found to contain variables that were underrepresented were. combined to identify and map regions with under-represented characteristics. The …
