The PeatPic project: Predicting plot-scale green leaf phenology across peatlands

This dataset comprises standardized plot-scale photographs and associated
metadata collected from 42 peatland research sites during the 2021 and
2022 growing seasons. Using the PeatPic protocol, participants
photographed dominant vegetation communities weekly to bi-weekly from
pre-growth through senescence, capturing seasonal dynamics across bog,
fen, and swamp ecosystems. Metadata includes vegetation type, microform,
site characteristics, and disturbance history. RGB imagery was analyzed
using the Phenopix R package to derive a greenness index, and seasonal
trajectories were modeled using a Gaussian function to estimate the timing
and magnitude of peak greenness. These data support cross-site comparisons
of peatland green leaf phenology (GLP) and facilitate broader
investigations into vegetation responses to climate and disturbance.
