Trade-offs in berry production and biodiversity under prescribed burning and retention regimes in boreal forests

摘要

1. Green tree retention and prescribed burning are the practices used to mitigate negative effects of boreal forestry. Beside their effects on biodiversity, these practices should also promote non-timber forest products (NTFPs). We assessed: (1) how prescribed burning and tree retention influence NTFPs by examining the production of bilberry, Vaccinium myrtillus and cowberry, Vaccinium vitis-idaea; (2) if there are synergies or trade-offs in the delivery of these NTFPs in relation to the delivery of species richness, focusing on five groups of forest-dwelling species.
