A spatio-temporal dataset for ecophysiological monitoring of urban trees.

A dataset was produced for 117 urban trees in four monospecific tree rows in the city of Rennes, northwestern France. The trees were measured in nine 2- to 3-day measurement sessions from Apr-Sep 2021. The dataset includes (i) leaf traits (, contents of pigments, water and dry matter) measured and in the laboratory; (ii) plant area density measured under the canopy and (iii) georeferenced data that describe the location, geometry and species of the trees.
