In recent years, urban models that traditionally describe the built environment have evolved towards digital twins. Advanced platforms also allow for taking temporality into account. This also brings interesting new opportunities for vegetation modeling – how to model growing trees and shrubs, seasonal changes, or the effects of climate change. In December 2024, the HRI Loves Developers: Modeling the Natural Environment remote event was organized. The event addressed the issues of modeling the natural environment from the perspective of urban modeling. In addition to vegetation modeling, the discussion focused on the format in which new data should be collected to make it interoperable between different cities. In addition, among other things, consideration was given to how to support the operating conditions of science-based small businesses operating within the framework of urban ecology when considering the structure of data.
