- Abstract
In order to improve biological diversity in managed and protected forests it is necessary to develop suitable management methods. Woody debris, especially with large diameter, is of great importance for sustaining biodiversity. To maintain this diversity, continuity of woody debris in space and time is required. There is a lack of knowledge about decomposition rate of woody debris in the boreo-nemoral zone. In order to develop management plans and to ensure continuity of woody debris such knowledge is important. We selected 9 circular plots (15-m radius) in relatively undisturbed (by humans) Norway spruce (Picea abies (L.) Karst.) stands located in the southern part of Kemeri National Park. Diameter of snags and logs was measured, only those with diameter ≥0.2 m at 1.3 m above the original ground level were used for our study. All logs were classified according to decomposition stage using a 5-point scale. To determine time since death of a tree, we collected cross-sections and cores for cross-dating. For the master chronology we used cores collected from living trees growing nearby. In cases when cross sections and cores were considered undatable, due to high degree of wood decomposition, cross sections of saplings and cores from nearby trees were collected for "growth release" analysis. In total, 70 logs were measured and dated.
