Mountain Watch is an ongoing trail-side citizen science program that tracks plant development, aka phenology, of a small set of alpine and forest plants in the Eastern Appalachian mountains and other Northeast areas. AMC is also a partner with the USA National Phenology Network, the National Park Service, and the Appalachian Trail Conservancy in the AT Seasons project. This endeavor tracks plant and animal development along the AT corridor. Similar to AMC’s Mountain Watch, AT Seasons (https://www.usanpn.org/appalachian) will provide much needed information on climate impacts at upper elevations. These citizen science programs are components of the Appalachian Mountain Club alpine ecology and climate science research being conducted in the Northeast mountains.
