“…Niemel~i et al, 1988). One component of the primeval forest is considered to have exceptionally high species diversity: the wood-decomposing system (Speight, 1989;Albrecht, 1991;Rauh and Schmitt, 1991). Nevertheless, the sub-cortical fauna in the managed forests surrounding the Pyhii-Hiikki National Park has not previously been investigated owing to the scarcity of decaying wood.…”

The sub-cortical beetle fauna of dead Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) trunks was compared in primeval forests and managed forests in central Finland. The numbers of both individuals and species were higher in the managed forest in spite of the smaller trunk surface area examined. The proportion of rare species was higher in the primeval forest. Although most species occurred both in primeval and managed forests, there were striking differences in the abundance relations: there was only one species (Pytho depressus) in common among the ten most abundant species. The proportion of bark beetles (Scolytidae) was more than 50% in the managed forests, and less than 5% in the primeval forests. The number of species per site was associated with observation date, occurrence of snails and trunk position (standing or lying) in the primeval forest, and with trunk diameter in the managed forests. The occurrence of rare beetle species in dead conifer trunks was related to man's effects on the forest. Although many sub-cortical species can live in managed forests, the fauna differs drastically from that of primeval forests.

“…In virgin forests and seminatural forests in Germany, the volume of dead trees ranged from 50-200 m 3 ha -1, whilst in forests under conventional management it ranged from 1-5 m 3 ha -1 (Albrecht, 1991). Only a few studies appear to have been made on the amount of dead wood in northern European forests.…”

“…Decay class was assessed for each log and measurement position according to a 4 stage classification system (Albrecht 1991 for P. abies and P. sylvestris), modified for F. sylvatica by Müller-Using and Bartsch (2009). Based on the decay class and the associated known wood densities, log volumes assessed in field inventories can be converted into CWD mass and C content (Grove et al 2009).…”

Decomposition dynamics of coarse woody debris of three important central European tree species

Background: Coarse woody debris (CWD) is an important element of forest structure that needs to be considered when managing forests for biodiversity, carbon storage or bioenergy. To manage it effectively, dynamics of CWD decomposition should be known. Methods: Using a chronosequence approach, we assessed the decomposition rates of downed CWD of Fagus sylvatica, Picea abies and Pinus sylvestris, which was sampled from three different years of tree fall and three different initial diameter classes (>10 -≤ 20 cm, >20 -≤40 cm, >40 cm). Samples originating from wind throws in 1999 were collected along a temperature and precipitation gradient. Based on the decay class and associated wood densities, log volumes were converted into CWD mass and C content. Log fragmentation was assessed over one year for log segments of intermediate diameters (>20 -40 cm) after 8 and 18 years of decomposition. Results: Significantly higher decomposition constants (k) were found in logs of F. sylvatica (0.054 year

“…An impressive resource of literature has now accumulated on the ecological role of deadwoods in forests (e.g. symposia held in Chambéry, France in 2004, Mantova in Italy in 2003 and in Reno-Nevada, USA, in 1999; studies in the UK [4,10], Germany [1,2,17], Poland [6] and Scandinavia [9]). A useful reference resource is the WWF booklet 'Deadwood -living forests', published in 2004.…”

The Ecological Role of Deadwood in Natural Forests

Veteran and dead trees at different stages of decay have an important ecological role to play in conserving forest biodiversity and are recognized as Pan-European indicators of a sustainable management.Dying and dead trees, either standing or fallen and at different stages of decay, are valuable habitats (providing food, shelter and breeding conditions, etc.) for a large number of rare and threatened species: saproxylic insects, invertebrates, lichens, bryophytes, birds and mammals. Hollow trees, in particular, provide suitable microhabitats for mammals (e.g. rodent species, squirrels, martens, bat species and wild cats) and cavity-nesting birds (e.g. woodpecker, tit and owl species).In natural forests in Romania, deadwood is associated with several relict, rare and protected animal species (e.g. Rhysodes sulcatus, R. americanus, Cerambyx cerdo, Lucanus cervus, Rosalia alpina, Camponotus herculeanus). Many lichens (Parmelia, Peltigera and Lobaria species) indicate the continuity of natural forests and the presence of more than 20 species of fungi contribute to the ever-present processes of decay. Large quantities of deadwood (50-130 m 3 /ha) also play a significant role in forest nutrient cycles, carbon budgets, soil morphology and natural regeneration. Natural forests in Romania provide exceptional conditions for research into the ecological role of deadwood habitats.
