Influence of Regeneration Method on the Yield and Stem Quality of Black Locust (Robinia pseudoacacia L.) Stands: a Case Study

Black locust (Robinia pseudoacacia L.) is one of the most important forest tree species inHungary, covering approximately 23% of the forested land and providing 25% of the annual timberoutput of the country. One third of these black locust stands are high forests (planted with seedlings)and the remainder coppices. According to the forestry regulations black locust stands can beregenerated both by root suckers and with seedlings in Hungary. This study investigates the influenceof different regeneration methods on wood production, stem quality and health. Properly managedregeneration from root suckers produced a higher yield than regeneration from seedlings at a harvestage of 35?37 years. The results show that regeneration of black locust stands from root suckers can berecommended on good and medium quality sites without a decrease in yield or stem qualit
