  1. Landscape Fragmentation in the Lake Champlain Basin Charlotte Low Matt Gustafson Walker Brown Photograph: Caldwell Clark 2010 (Mt. Philo)

  2. Problem Statement Land Fragmentation, resulting from agriculture, industry, urban development, and transportation networks, in the Lake Champlain Basin, has a dramatic effect on the function, value, and quality of wetlands, forests, and herbaceous landscapes through disrupting the natural dynamics of these systems.

  3. Connections Matrix

  4. Goals • Develop an assessment of land fragmentation and its effects on habitats • Construct a relative risk ranking system and link/importance matrices Photograph: http://farm5.static.flickr.com/4153/5051555848_10a02fbe4e.jpg • Objectives • Research previous studies • Develop a diagram illustrating the existing connections • Create GIS maps analyzing land use and transportation networks • Assign risk rankings by sub-watershed Photograph: http://img5.visualizeus.com/thumbs/df/9c/eden,animals,bear,forest,road,funny-df9ceec4b92e8091ca15aa48d791f795_h.jpg

  5. Effects of Fragmentation • Habitat Loss, Isolation, Separation • Edge Effects • Decreased Connectivity • Biogeography • Loss of Biodiversity • Genetic, Species, Ecological • Increased Mortality • Predation, Collisions, Exposure Photograph: http://3.bp.blogspot.com/_ey0cXXT2kz8/TTN8AzmashI/AAAAAAAAFNk/5Ammw0HXRtQ/s400/EasterBunnyRoadKill4406.jpg

  6. Approach • 2 Phase Approach • 1st – Literature Review to direct link and importance matrix's • 2nd – GIS Analysis • Unique approach for land fragmentation as a stressor

  7. Findings

  8. Connections Matrix

  9. Conclusion/Management Recommendations • Ideally the sources of landscape fragmentation; roads, urban areas, agriculture, and recreational parks, can be controlled and reduced in the future. • Adopt policies and zoning regulations which keep populations localized around urban centers and villages and protect important wildlife corridors • Establishment of riparian buffers and wildlife corridors
