Workshop, Copenhagen, 5/05/2014 Changes in the structure of tree stands on boreal spruce forest in the Białowieża

The boreal spruce forest association changed their tree stand composition by increasing numbers of broadleaved species typical for mesotrophic broadleaved forest such as: Quercus robur, Carpinus betulus and Acer platanoides. The increasing share of Corylus avellana was observed in the shrub layer.

The major change was a quantitative increase of the late- successional species: cordata and Carpinus betulus.

„It was probably caused by a lack of major disturbances during the study period.”

Species preferring old growth dense forest:

• Pytho kolwensis Typical habitats are virgin spruce-mire forests with a stand continuity of at least 170-300 years, and a high volume of dead wood (70-110 m3/ha).

• Wrinkled Bark Beetle - Rhysodes sulcatus Habitat is old growth forest with high amount of dead wood.

• Lucanid beetle - Ceruchus chrysomelinus Inhabits forests with a high density of moist red-rotten logs of both coniferous and deciduous trees.

Disturbances creates habitats for many species. For example mass dieback of ash caused by fungal pathogen Chalara fraxinaea creates optimal habitats for endangered beetle Cucujus cinnaberinus, ie. high amount of dead standing trees on wet, sun exposed sites.

Workshop, Copenhagen, 5/05/2014 Conclusions

Strict protection of old growth forest safeguard continuity and high amount of dead wood, what creates habitats for many saproxylic species.

The increase of shadowing caused by trees and shrubs development due to succession changes is the main danger for the species occurred in more open forests conditioned by pasture and fire disturbances.

However there are as many species which cannot be successfully protected in strict reserves. Those species except of continuity of dead wood, demand also specific conditions for example related to high requirements concerning sun exposure. To safeguard those species active conservation measures are required.

The spontaneous regeneration and raising of habitat fertility conditioned by both historical factors (changes in forest use) and those ongoing today (the influx of biogenic compounds from the atmosphere and climatic change) is merely increasing the degree of non- concordance between the species and the habitat in which they occur.

The strict protection implemented on the considerable area of the BNP ensures maintaining of natural processes of plant communities regeneration. The implementing of such protection pattern in areas, where plant communities were formed as a result of centuries of extensive agricultural use and fire, leads to vanishing of same species.
