摘要：As the human population has grown significantly in the last 20 years throughout New England, Southeastern New Hampshire hasbecome increasingly susceptible to issues associated with urban development and sprawl. Urbanization has increased the amountof impervious surface in the area as well as fragmented many of the crucial habitats, especially forests. Mapping and analyzingthese fragmented habitats is of critical importance for conserving and protecting critical habitat for water quality, wildlife, andquality of life. Several methods for quantifying fragmented landscapes have recently been developed. These techniques include:FRAGSTATS (University of Massachusetts), the Forest Fragmentation program from the Center for Land Use Education andResearch (CLEAR, University of Connecticut), and a number of other image analysis techniques. This project used the NationalLand Cover Dataset Land Cover Retrofit product of Coastal Watershed, NH to evaluate various fragmentation techniques. Inexploring the results from FRAGSTATS and the CLEAR Forest Fragmentation program, we found no significant difference inthe land cover fragmentation between 1992 and 2001. These two methods were compared to determine the strengths andshortcomings of each. The CLEAR program provided the advantage of visual results while the FRAGSTATS results were onlynumeric. We found that each of these methods alone is insufficient to precisely map fragmentation, especially when applied tothe National Land Cover Dataset maps. Our continued work will be to develop a tool that combines the best of these techniquestogether to better map and analyze fragmentation
