A forest trees production establishment and setting up for the restoration of watercourses banks.
The main objective of the project is the establishment of an origin secured production line of forest trees to protect and stabilise banks. The choosen trees species are : the black alder, the willow and the ash tree. The second objective is to store dormant trees in cold room till they are planted along the watercourses when banks are accessible. Third, the establishment and the management of stock-plants nurseries will be necessary to produce plants of certified origin.
Willow hardwood cuttings after 2 months and black alder rooted cuttings prepared for storage
After having prospected and fixed different origins in the 3 eligible regions : Wallonie – Lorraine and Grand Duchy of Luxemburg, we have to propagate these clones by cuttings or by in vitro culture. Planning and maintenance of stock-plants to provide cuttings continuously will be realised
Our previous work have showed that the black alder propagation by mean of cuttings was quite easy if we used young or rejuvenated stock-plants. About 50 different alder clones issued from the Walloon Region have been fixed and are already used as stock-plants for propagation. More than 200 clones of willow trees have been collected in the Walloon Region and are growing outside. Ash tree is more difficult to propagate by cuttings. Complementary trials are needed to improve this species rooting.
