Does black locust performs in any forest sites?
Black locust is a non-native tree species introduced in Romania like an ornamental tree around 1750. One hundred years later the first plantation was established. The fast-growing capacity and apparently low ecological requirements made black locust so attractive that it was established not only in suitable sites but also in unsuitable sites, in these last cases with unsatisfactory results. Examples are stands with black locust from Razboinicu Working Circle, Forest District Strehaia. Data from management plans were analyzed for pure black locust stands and mixtures in terms of age, composition, regeneration pathway, and yield. More than 70% are pure stands; others are mixtures with oaks (Turkey and Hungarian oak) and other tree species like European hornbeam, field maple, European aspen, European ash, field elm. Stands older than 20 years are usually mixtures with a small percent of black locust. There are different regeneration pathways, stump stools, and root suckers in case of old stands, plantation for some the younger stands. The productivity is lower than the average national yield table for similar pathway.
