Conservation and propagation of Pyrus L. species in the greater Caucasus: integrating biodiversity strategies with "Green Economy" principles

This study investigates conservation and propagation strategies for Pyrus L. species in the Greater Caucasus, integrating biodiversity preservation with “green economy” principles. Using in situ and ex situ assessments—including tissue culture, morphological analyses, and germination trials—we identified Pyrus salicifolia Pall. as a prime candidate for restoration. Results highlight adaptive divergence between wild and cultivated populations, and classify four species as Vulnerable or Near Threatened. The findings demonstrate how targeted conservation can enhance ecosystem resilience, support sustainable agriculture, and foster long-term socio-economic benefits.
