More Trees Consultancy B.V. has given an ACT team of Wageningen University the task to carry out a literature research on growth tables and management plans about Robinia pseudoacacia (Black locust) in Europe. Black locust is a deciduous, nitrogen fixing tree, originated from North America and valued for its many purposes (saw wood, furniture, biomass, honey production, nitrogen fixation etc.). The tree is used as a crop tree on plantations in many countries in Europe. However, due to ecological, economic, and socio-cultural conditions, the profits from these Black locust plantations differ very much between countries and sites. With optimization of the profit from Black locust plantations as the main goal, this research project involves three parts:
1 - Compilation of all found available information on growth tables of Black locust
2 - Case study on two plantation sites in Europe (France and Hungary respectively) with the aim to develop two management plans concerning the cultivation and maintenance of Black locust, with different cultivars and tending operations
3 - Economic analysis, involving a cost and benefit analysis and an economic model to simulate profit outcomes.
Furthermore, it is clear that there are many differences in yields of Black locust, depending on soil type, cultivar, climate etc. High yields can be found for example on former agricultural soils in young stages of Black locust plantations.
Based on a comparative analysis, the case study highlights that the France has possibilities for profitable Black locust plantations in comparison with Hungary, making use of More Trees Consultancy clones. However, according to the economic model, this is only advantageous for big estates. In Hungary, total costs for management, cultivation etc. are much lower compared to France, but environmental conditions are less suitable. More research on prices, conditions and economical processes is necessary to come up with reliable conclusions and recommendations. Nevertheless, it is clear that the Black locust has a high economical value as construction material and it provides possible profitable alternatives for biomass production.
