Chronolog – Taking pictures for nature

Recently on a walk at a new local park, I came across a placard and place for my phone with instructions to take a picture of the area and email it. The system is from a startup called Chronolog. I had never seen anything like this on my walks through other local parks. Apparently, they’re using it to target specific areas for a variety of issues.

Chronolog sign post with bracket to take a picture that I took a picture of to remember where to email the photo later.

I like being able to do my part to help build the time lapse and give them more information about the park.

I couldn’t find anything about it on my county’s web site, but Greenbelt, MD had a news article about the system from September 2018.

When asked about what these stations are and how they should be used, Ky Wildermuth of Chronolog said “The idea was to create stationary reference points that would position cell phone cameras in a specific direction. Park conservationist would mount brackets in front of ecosystems they needed to monitor. People who ventured out into these areas could place their phone into the bracket, take a picture, and email it to be compiled for a time lapse. That time lapse could be analyzed to track plant life, a restoration project, or environmental change.”

The email I got back in confirmation and thanks said what they were looking to monitor with this particular site.

The North Branch Rock Creek flows directly into Rock Creek and ultimately into the Potomac River. This site is a popular creek crossing. We hope to monitor bank erosion and channeling of this creek.

Unfortunately, there is not a public-facing page for the site I contributed to but here’s an example from their site of the Vernal Pool that goes from dry to wet land as the seasons change.
