Please join the Appalachian Mountain Club (AMC), Adirondack Mountain Club (ADK), Green Mountain Club (GMC), and Baxter State Park (BSP) in documenting flowering times of plants in northeast alpine areas.

By sharing photo observations using iNaturalist from your next hiking trip above treeline, you can contribute to ongoing phenology (timing of biological events) research. Your photos can become research-grade data that will help us discover, monitor and ultimately conserve these unique and treasured mountain ecosystems.

The more photos that are posted on iNaturalist, the more we can capture the large variability that is inherent in mountain environments across space and time in the northeastern United States. This data will be merged with our ongoing plant phenology studies and used to discover long-term trends in mountain ecosystems. Northeast Alpine Flower Watch is funded by the National Geographic Society.
