Following the Flowers: Tracking Appalachian Plant Phenology with iNaturalist

Aiesha Parmar, Ecology Assistant – Scientists in Parks with the Appalachian Mountain Club, will present a project studying plant phenology along the Appalachian Trail corridor.
Since 2004, AMC has been tracking flowering and fruiting times of plants across Appalachia, with help from hikers and naturalists. AMC administers multiple iNaturalist projects as part of our efforts, notably the Flowers and Fauna along the Appalachian Trail Corridor. The observations on these projects help AMC researchers study how climate change is affecting seasonal patterns in plants along one of the largest expanses of minimally disturbed temperate deciduous forest– the Appalachian Trail corridor.
