Phenology can be considered Nature’s calendar. It is the study of seasonal and cyclical changes in plants and animals, like the flowering of plants, the emergence of insects, or the migration of birds.
The timing of these events are influenced by environmental triggers (sunlight, temperature, and precipitation) making phenology a leading indicator of climate change.
Phenology records around Mohonk Lake date back to 1925, when Daniel and Keith Smiley started noting the date of spring bird arrivals. The Preserve’s Daniel Smiley Research Center continue this tradition of natural history observation and have expanded the scope of the Smileys’ phenology records to monitor seasonal changes in plants and other fauna at Mohonk Preserve on local, regional, and national levels.
Mohonk Preserve Phenology Trail
Phenology Project Volunteer Observers document distinct stages in select trees, shrubs, spring ephemerals, butterflies, amphibians, and reptiles throughout the year.
- Foothills Phenology Trail
- Originated in 2014
- Located on the Mohonk Preserve Foothills near the iconic Testimonial Gateway tower.
- View the 2016 Mohonk Preserve Foothills Phenology Trail Map
- View the 2017 Mohonk Preserve Foothills Phenology Datasheet
Volunteer as a Phenology Observer
- Join a dynamic group of volunteers
- All ages and experience levels are welcome
- No prior science or research background required
- Receive training and group learning opportunities and workshops
- Spend time outdoors
- Scheduling incredibly flexible
- Hone skills in data collection, species identification, and botany
- Gain a deeper understanding of the local impacts of climate change
- Receive the Phenology Trail Newsletter to see what is happening out on the trail
When and How to Observe
- Once trained, volunteers observe on their own schedule
- Observers look specific life cycle stages occurring for a given species at each visit.
- “Negative data” is collected too (observation continues during the winter months, even when observed species are mostly dormant)
Our Species List
Plant profiles featuring photographs of key phenophases for many of our species, can be found on the New York Phenology Website.
Connections Regionally and Nationally
Mohonk Preserve’s Phenology Project is a participating member of the New York Phenology Project, a regional network of preserves, nature centers, and educational institutions working together to study climate and urbanization impacts on plants and pollinators.
On a more national note, The Phenology Project uses protocols developed by the USA National Phenology Network (USANPN) for their program, Nature’s Notebook. This data is immediately available to scientists, land managers, educators, and citizens everywhere to answer questions about how plants and animals are responding to environmental change.
