Complete Species & Cultivar List included in the GALK 2022

The list of species and cultivars included in the GALK Street Tree List (April 2022) constitutes a taxonomic inventory of tree taxa assessed by the German Working Group on Urban Trees for their functional performance in street environments. Each taxon is evaluated with respect to growth morphology, dimensional parameters, light transmission (L1), light requirement (L2), physiological tolerance to urban stressors, and overall suitability for use in constrained or highly anthropogenic planting sites.
