Continuous cover management on peatland forests has gained interest in recent years, part because the tree biomass with significant evapotranspiration capacity retained selection cuttings could be used as a tool to optimize site water table level (WTL) from both growth and environmental perspectives. This study reports WTL responses six field trials established fertile Norway-spruce-dominated drained across Finland. At each site, replicates of different intensity (removing 17–74% stand basal...
Continuous-cover forestry (CCF) is expected to reduce the negative environmental impacts of peatland in comparison with rotation (RF), but unknown profitability CCF on peatlands limits its application practice. The was analyzed by simulating management scenarios a process-based ecosystem model, EFIMOD, which complemented describe interplay between tree growth and water table depth, typical forests. A variety harvest intervals post-harvest basal areas for mature Norway spruce (Picea abies...
<ja:p>An imbalanced nutrient status in Scots pine stands on drained mires is primarily a consequence of excess nitrogen (N) relation to mineral nutrients such as phosphorus (P) and potassium (K). In this study, the variation foliar N, P, K concentrations relative some site environmental characteristics was examined. Foliar were determined needle samples collected from representing different drainage ages, types, geographical locations annual weather conditions. overall data (n = 971 333...
Strip-cutting management has been proposed as an alternative to clear-cuts in drained boreal peatland pine (Pinus sylvestris L.) forests. We explored the hydrological feasibility of strip cutting, that is, under which conditions post-harvest water table (WT) peat remains sufficiently deep (here, a WT −0.35 m during late growing season) enable undisturbed tree growth. approached question by (1) measuring WTs harvested and adjacent unharvested stand forests southern Finland (2) simulating...
Treatment of conifer stumps with a control agent effectively prevents Heterobasidion spore infections in summer cuttings and protects the residual stand next tree generation from damage caused by root rot. Thus far, stump treatment experiments have been carried out mineral soils, no information is available on efficacy agents boreal peatland conditions. In present study, biological chemical (Phlebiopsis gigantea urea, respectively) were tested Scots pine Norway spruce stands subjected to...
<ja:p>A large proportion of drained spruce mire stands is currently approaching regeneration maturity in Finland. Traditional methods with effective site preparation and planting generally result satisfactory seedling also mires. However, natural may be more appropriate protecting watercourses minimizing costs. We studied the survival advance growth establishment new seedlings small canopy openings that were cut at three different diameters two experimental Northern Finland (Tervola Oulu)...
<ja:p>Watering up typically ensues after clearcutting forestry-drained peatland forests. Thus, the effectiveness of maintenance drainage and soil preparation procedures becomes paramount for establishing a new generation commercial forest. Mounding is primary method applied in regeneration sites lying on deep peat. As raised planting spots, mounds are resistant to waterlogging assumed be beneficial organic matter (OM) decomposition via, e.g., increased aeration temperature, which would also...
<ja:p>A large proportion of drained spruce mire stands is currently approaching regeneration maturity in Finland. We studied the effect cutting â small canopy openings (78, 177, and 314Â m) clear-cuts (0.25â0.37 ha) with or without site preparation (scalping) on establishment natural Norway seedlings one experimental stand northern The cuttings were made winter 2004â2005 scalping early June 2005. design was composed four blocks altogether 33 openings. seedling surveyed annually (2006,...
We studied the establishment of natural seedlings after seed tree cutting and scalping in two drained Scots pine peatland stands northern Finland (Simo Sievi). Approximately, 50 ha−1 stems were retained on both sites. During six subsequent years, five seedling surveys conducted. The effect site preparation was analysed using generalized linear mixed models (GLMM). mean density increased more quickly scalped plots ca. 1.1 m−2 years compared to 0.87 non-scalped plots, average. Scalping number...
Artificial and natural seeding of Scots pine in old drainage areas – Unique features forest regeneration on peatlands The aim this dissertation was to investigate site characteristics unique nutrient-poor, forestry-drained from the standpoint establishing second post-drainage generation forest. Specifically, effects ground vegetation succession, surface peat structure composition, water table level, retention capacity success after articial were examined. As Sphagnum moss cover declines...
AbstractThe need to regenerate peatland forests is expected increase in the near future Finland due harvest of large amounts peatlands drained during 1950s and 1960s. In anticipation this, a new type excavator-mounted rototiller for soil scarification has been developed improve moisture conditions seedbed by mixing ground vegetation, raw humus layer, peat. The regeneration result was compared with traditional patch (i.e. scalping) direct seeding Scots pine three forestry-drained sites...
Abstract We studied the effect of regeneration (planting/seeding) and soil preparation methods (no preparation/scalping/mounding) on success Scots pine ( Pinus sylvestris L.) three drained peatland stands in northern Finland. After ten years, planting sowing showed no differences total number seedlings (one seedling per spot accepted) with exception Sievi experiment. Without was 350–600 ha. Scalping increased to 550–900 ha, seeding at Sievi. In mounded plots, seeded plots site, planted or...
