摘要

Site conditions, vegetation and structure of Norway spruceforests situated on peat bog margins (two natural, one slightlydrained) in Bavarian Forest National Park (Germany)were studied on three transects.Spruce forests of bog margins exhibit mean water levels of27 cm under natural conditions, and 47 cm below surfaceafter draining, high cover of Sphagnum mosses and highvariance of tree diameters. They are distinguished fromspruce plantations by high tree ages, low site index (< 25 mdominant height at age 100) and high deadwood stocks.Water levels, cover and composition of the Sphagnum layerindicate that they might act as net carbon sinks. As a richlystructured component of natural zonations spruce forestsof bog margins deserve the attention of nature conservation.Close-to-natural stands should be preserved and left tonatural development. Structural and ecological criteria forrecognizing such stands are developed. In bog restorationsuch spruce stands should not be dismissed and possibly removedas unnatural spruce plantations. Moderately drainedspruce stands can be restored to a more natural state byslowly raising the water table.
