- For ten years the Adirondack High Peaks Summit Steward program has utilized photopoint monitoring to document changes in alpine vegetation with a particular focus on areas subject to human trampling. Photopoints are photographs of a landscape area taken repeatedly from the same exact position, showing qualitative changes over a set time.
- In 2009, 40 of the 50 photopoints were re-taken, using a combination of film and digital cameras. Images were analyzed to examine changes in percent photocover of bare rock, exposed soil, and vegetation.
- Photopoint series were compared between mountains with regular steward presence versus mountains without a regular steward presence and showed a significant difference in change in vegetation over time.
