USING HIGH-RESOLUTION SATELLITE DATA AND PHENOCAMS TO TRACK SPECIES AND SITE-DEPENDENT VARIABILITY IN URBAN VEGETATION PHENOLOGY

Vegetation phenology is an important characteristic of plant ecology. However, there is an absence of research on urban phenology at the individual species and spatial level. This research used high spatial and temporal resolution satellite data and phenological cameras to map urban tree phenology to determine the role of species and site characteristics within the single year and interannually. This study found that species have a role in determining phenological variability, with different tolerance to the temperature changes during the Start of Season, Summer Shoulder, and overall green-up period. Site factors, such as canopy and impervious surface coverage, was not statistically significant for influencing the timing of phenometrics. This may be due to influences that cause variability in phenological signal and should continue to be studied. These findings provide novel data on the plasticity of urban trees and layout of urban phenology monitoring using phenocams.
