While working on the Appalachian Trail, I realized that many of the campsites used year in and year out by Thru-hikers are growing in size and degree of impact. Yet, many of the organizations tasked with monitoring campsites keep records in paper form and have no tangible concept of the way impacts are adding up.

In the video above, I used ArcMap to enter in a hypothetical centerpoint for a campsite. I then compile polygons, representing monitoring trips. Ideally, this data would be collected in such a way as to contain monitoring metrics in the attribute table, so the symbology can be classified by the severity of impact.

The video shows how one campsite grows over time. Typically, however, campsites don’t exist in isolation. This technique can be expanded to show multiple campsites bleeding into each other.

The area data can be compiled in either excel or R, and used as an input to a linear regression analysis. This can be used to project, that if impacts continue at the current rate, they would result in campsites over ever increasing size, until you wind up with giant camping areas.

By finding trouble spots on the trail and analyzing them over a five year period, enough data can be compiled to extrapolate useful modelling, which can help inform better management decisions.

Currently management decisions are being made without data to show whether they are working or not. Anecdotally, the impacts appear to get worse every year. Management and monitoring need to go hand in hand. When a decision is made, the impacts of that decision need to be monitored and that data needs to inform future decisions. Otherwise, we cannot be said to be making rational decisions.
