Robinia pseudoacacia L. in the Western Caucasus

Robinia pseudoacacia L., commonly known as black locust, does not reduce arboreal species diversity in riparian forests of the Western Caucasus despite its increasing dominance over native tree species. The study, conducted by Akatov et al. (2016), reveals that while R. pseudoacacia is most abundant where native dominants hold a middle-level presence, its proliferation does not negatively impact overall forest diversity. Researchers analyzed distribution, age structure, and population dynamics across the region, finding that most individuals are under 20 years old, suggesting rapid colonization but limited long-term persistence. The study highlights the resilience of riparian forests to invasive species, offering insights into ecological succession and conservation strategies for UNESCO World Heritage Sites like those in the Western Caucasus.
