Oyster reefs and salt marshes are dominant, intertidal habitats that provide the foundation of ecosystems and exhibit noticeable changes over time. We placed the repeat photography stations to view a mudflat with natural reefs of different shapes and sizes, as well as marsh habitat with varying plant species across an elevation gradient. We also installed a station overlooking a new oyster castle, a type of artificial substrate used in reef habitat restoration, to illustrate how restoration projects progress over time.
Since installing the five stations in summer of 2021, we’ve already received over 150 photo submissions. Through these images, we’ve documented episodic events of rafting (or wrack) along the marsh and macroalgae on top of the oyster reefs. With longer time-lapses and a changing climate, I expect we will see shifts in marsh plant communities, oyster reef structure, and the shorelines over the coming years.
Many of these changes are being documented with long-term data collected by scientists working with the Virginia Coast Reserve Long-Term Ecological Research (VCR LTER) program. This 35+ year program uses long-term studies and monitoring to better understand the present and make future predictions of coastal ecosystems. The outputs of the outreach tool will contribute a unique collection of data to the VCR LTER program because it’s the first dataset of photos viewing the same landscapes over long spans of time. This type of dataset can spark new research questions and reveal changes not yet observed with the VCR LTER’s existing datasets. The time-lapses are also a way to bring long-term data to the public in a simple, accessible way.
In addition to outward engagement and ongoing scientific research, the processing and analysis of photographs offers another opportunity for the community to get involved. In August of 2021, I presented an overview of our outreach tool to K-12 educators from Accomack and Northampton Counties participating in a nature-based education workshop led by The Nature Conservancy. Alongside the teachers, we brainstormed ideas about how repeat photography could be used in their classrooms for educational purposes. We discussed different types of scientific data that could be gathered from the time-lapse imagery to support their classroom curriculum, such as plant and animal identifications, cloud cover, and tidal heights.
Although COVID-19 put a lot of my plans for field research on hold and added stress to earning a Ph.D., co-developing this outreach tool with Serina has been a silver lining. We started planning when quarantine first began in 2020, in a time when we were all seeking some sense of normalcy. Watching these time lapses and seeing our idea come full circle has been really rewarding. We’ve unlocked a tool that has increased accessibility, made connections with the local community, and introduced a new method of long-term monitoring for scientific research.
