Structural diversity of abandoned chestnut (Castanea sativa Mill.) dominated forests: Implications for forest management

► Under no management chestnut is outcompeted in the overstorey by admixed species. ► Chestnut blight is a major stress factor and an important driver of species decline. ► Retained seed regeneration potential of chestnut is ascertained. ► Management of chestnut in high forests alternative to coppices is advocated.
