The appearance and surface relief of bark impress with their diversity, determined by species characteristics, plant age, and growing conditions. Considering that the correlation between bark architecture and its response to ecological stresses remains largely unexplored, the distribution of Douglas fir trees was traced based on bark type in a uniform-age stand in the forest-steppe of the Voronezh region. It was established that already at 40-45 years, when differences in bark become noticeable, effective forest management activities can be conducted, and seeds can be collected for selective breeding based on this trait. Trees with cracked bark type should be designated for thinning, excluding them from the prospective seed fund.
