Photo point monitoring is a method of repeat photography used to track changes on the landscape through time. One of the most well-known series of repeat photographs is the Mountain Legacy Project, which is recreating historical photos dating back to 1861 in the Canadian Rockies.
Here at Splitrock we use this technique to monitor the progress of re-vegetation on our ecological restoration projects. Below are two images from our Powerhouse site. The first was taken before restoration work in 2010, and the second one was taken almost exactly two years later after we had begun to remediate the soil, and re-plant the area with native wildflowers, grasses, and shrubs.
Currently, we are working on establishing permanent photo points at all of the wetlands in the Lillooet area. We hope to return to these photos through the years to monitor the health of our wetlands. Each image includes the surrounding landscape, because wetlands are dynamic features, which may grow, shrink, or move in response to human alterations on the landscape, ecological succession, geo-morphological processes, and climate change.
We would like to work with landowners and community members to re-monitor the photo points at each of our wetlands, so we are developing protocols, data-sheets, and other resources to help train new users on this exciting and powerful technique. If you are interested in photo point monitoring, or if you have a project which would benefit from repeat photography, please contact us, we would love to share what we have learned.
