In the present study the cultivation and management of Black Alder (Alnus glutinosa (L.) Gaertn.) in Estonia are researched, and some recommendations are given. Black alder grows in all parts of Estonia, but Black Alder stands can more frequently be found in eastern and southwestern parts of the country. Due to the low stemwood quality in natural stands, the cultivation of black alder is recommended. Suitable areas for such cultivation are forest lands and also periodically excessively moist lands no longer used in agriculture, where the growth of many other species may tend to be poor or fail altogether. Black Alder is also a suitable species for afforesting wastelands produced as a result of oil shale mining. In Estonia conditions, the planting density of 2500 trees per ha is advised. Because of higher density of natural stands in young age, they should much be thinned. Very little is known about artificial pruning of Black Alder and therefore some more experiments are needed. To favour the natural pruning of Black Alder, the density of a stand has to be sufficient
