Chronolog is a citizen science environmental monitoring platform that enables public participation in time-lapse photography projects. It is used by parks, nature centers, wildlife organizations, schools, and museums to document ecological changes over time. Visitors to participating locations take photos at designated stations and submit them via email, contributing to crowdsourced time-lapse sequences. As of 2024, Chronolog operates in 48 U.S. states and 10 countries and has collected over 100,000 submissions since its launch in 2017.{{Cite web |last=Dietz |first=Nina |date=18 December 2024 |title=6 Creative Ways People Are Preserving Nature—And You Can Too |url=https://www.sciencefriday.com/articles/tiny-nature-triumphs-protecting-nature-roundup/ |website=NPR Science Friday}}{{Cite web |last=Cook |first=Meghan |date=13 March 2024 |title=Coming to a park near you: This clever phone mount frames up a stunning photo... and helps you save local wildlife |url=https://www.goodgoodgood.co/articles/chronolog-nature-time-lapses |website=GoodGoodGood}}
History
Chronolog was founded in 2017 by Jake Rose and Ky Wildermuth. The platform began with a small number of photo stations in state parks in Maryland, United States. Since then, it has expanded to include sites across the United States and internationally. Chronolog has been adopted by national organizations in the United States such as the National Park Service and Bureau of Land Management.{{Cite journal |last=Swann |first=Don |date=29 December 2023 |title=The Devoted People behind Big Data in National Parks |url=https://www.nps.gov/articles/000/the-devoted-people-behind-big-data-in-national-parks.htm |journal=Park Science Magazine |volume=37 |issue=2}}{{Cite web |title=Citizen Science |url=https://www.blm.gov/learn/science-in-blm/citizen-science |access-date=29 May 2025 |website=U.S. Department of the Interior Bureau of Land Management}}

Participating organizations–like state and national parks, wildlife preserves, museums, schools, local and state governments, nature conservancies, and wildlife nonprofits–install fixed photo stations at specific locations, typically overlooking landscapes of ecological interest. These stations guide visitors to align their smartphone cameras at a consistent height and angle. Users then email the photos to Chronolog, where software extracts metadata and assigns the image to a corresponding time-lapse sequence.
Each contributor receives an automated response with information about the site and the ecological changes being monitored. The aggregated photos form visual records that help track changes in vegetation, wildlife activity, water levels, and other environmental features.
Long-term ecological monitoring projects often face challenges related to cost, staffing, and continuity.{{Cite web |last=Brennan |first=Laura |date=10 July 2020 |title=Park Visitors Chronolog Ecosystems To Help Monitor Change |url=https://www.citizenscience.gov/2020/07/10/park-visitors-chronolog-ecosystems/# |access-date=2 May 2025 |website=CitizenScience.gov}} Chronolog's crowdsourced model has been adopted as a low-cost method to collect consistent visual data over time at participating sites.
