Whether it be over hours, days, or even years, we observe change over time in a variety of ways. Observations can be made in a changing landscape, how fast our kids grow up, the expansion of a town’s business district, etc. There may be old photos of a building when it was first built in the 1800s which we compare to how the same building may look today. In my own experience, a photo has been taken on my first day of school in the same spot every year by my mother. She now has the photos in an album showing how much I have grown up since the first day of kindergarten to the first day of college. I have found that over the years my favorite color to wear all of those years has been pink… and the funny thing is, it still is today! Ha! In what ways have you seen or documented changes over time?
Recently, the Stewardship Crew has been busy conducting point photo monitoring in the parks around Oakland Township. Photo monitoring is using photos (just like my first day of school photos!) to document the changes of a specific area in our parks over time. We may want to see how our work is reducing the abundance of invasive Phragmites, or see how which a patch of autumn olive is expanding.
The materials needed to do these observations are pretty simple and easy for anyone to acquire: a camera with a tripod, a zebra board as a scale to measure growth, GPS or map with the locations of the photo points, a compass to face the correct direction, notebook to record information, and a identification card for the site being photographed. Expense for these materials is relatively low, making repeat photography a favorable monitoring tool for land managers. Some of the materials can be seen in the photos below.

Keeping all the data organized in a binder is helpful

Photo monitoring is a great tool to show the changes in a landscape over time – how different management strategies change an area, how fast invasive species can take over, or a prescribed burn affects the plant community. Check out some of the photos from our parks over the years!
Bear Creek Nature Park – Interpretive Node
Wow, the autumn olive and trees are filling in quickly! Better stick that on the list of things to do.
O’Connor Nature Park – Phragmites patch
We treated the Phragmites in 2014 and 2015. Looking a lot better!
Paint Creek Heritage Area – Wet Prairie
Official photo monitoring began in 2011. The photos before 2011 were taken at approximately the same location as the photo monitoring point.
Photos should be taken in the same place at specific intervals, whether it be once each season, once a year in summer, or once every five years, etc. Over time the changes in vegetation can be observed and assessed by land managers to help inform future management goals or changes in management practices. Only time can tell what changes in an area or what will stay the same.
This is a great activity for local residents interested in volunteering with Oakland Township Parks and Recreation to participate in. It is a great way to see the parks in a different light, go to places in the parks you may not have seen before, and maybe learn something new about the native flora and fauna!
