Window to the Past: Providing a Framework for theFuture By Carol McNulty-Huffman Historians are fond of saying that those who forget the past are doomed to repeat it. Such thinking can be valuable for park nato- ral resource managers as well. Taking the timetolookatwhereyouhavebeenandwhat has happened in your park in the past can provide a valuable framework for determin- ing future direction. Often, however, with daily activities demanding your attention, it is difficult to find the time for reflection and research. In choosing atopic for my master’s thesis, I looked for something the park staff would find useful but probably would not have time to do on their own. Dave Haskell, Chief of NaturalResourcesandScienceatShenandoah NP (SNF’), expressed a desire for a compre- hensive record on the evolution of resource monitoring activities in the park. Ijumped at Big Meadow. an ecologically diverse open area at Shenandoah NP. is both a cultural and a natural the opportunity to dig through park files, old resource.
