英文摘要: Decline of dead wood in managed boreal forests has variously affected polypore species that use it as their substrate, some now being listed as threatened while some are still thriving. Management of polypore diversity requires species-specific information about their occurrence probabilities, which partially depend on stand dead wood availability and other properties. We implemented an ensemble of polypore habitat models to simulations of stand and dead wood availability estimated with a decomposition model we fitted to data. We asked how management of a boreal Norway spruce stand influences the dead wood availability and polypore occurrence probabilities and their diversity. Simulations of multiple polypore species with stand management scenarios provided insight to dead wood dynamics and polypore species management. In a managed stand, diversity thrived after final harvesting, but declined to low level by mid-rotation. Harvest residues and stumps, although low quality substrate for many species, were important for diversity in young managed stand due to their high quantities. High mixtures of naturalness in stand management were required to elevate diversity of managed spruce stands from the mid-rotation lows to levels in natural-like stands. Our study suggests that dead-wood supply of managed stands could be optimised to lift lowest species expectations towards levels in natural-like forests, but it seems that reaching these levels requires dead-wood quantities much higher than provided by conventional management. Management of stand diversity can presumably be facilitated with wise landscape planning but more research is needed in order to incorporate polypores to spatio-temporal management simulation context. © 2013 Elsevier B.V.
