Third Views: The Value of Repeat Photography for Long Term Environmental Monitoring in Grand Teton National Park, Wyoming
Abstract:
<p>Repeat photography is a valuable yet underemployed technique for long term environmental monitoring and management decision-making in national parks and protected areas. In its most basic form, repeat photography involves finding the location of a historic image, capturing a contemporary photograph of the same scene, and then comparing the two images. These photograph sets can reveal landscape changes over time such as the paths of receding glaciers or shifts in forest cover change. With careful analysis and interpretation, physical geographers, geologists, and other environmental scientists can trace habitat loss, climate change, biodiversity, and ecosystem resilience. The technique also offers a portal for human geographers and social scientists to better understand the long-term effects of environmental policy and management decisions and visitor use in national parks and protected areas. This paper contributes to this vein of scholarship with a case study of an ongoing environmental monitoring project in Grand Teton National Park (GRTE) along the Upper Snake River in Wyoming. Three sets of repeat photographs collected over a span of almost 50 years present opportunities to trace changes in river channel geomorphology, riparian vegetation, the effects of park management policies on river use and recreation, the cultural landscape evolution of boating access sites, concessions impacts, and wildlife management. Findings from this work will be of interest to a wide range of physical and social scientists, park managers, public lands stakeholders, and environmental conservation groups. </p>
