Events, facts, documents and evidence: Bark beetles pose an interesting, difficult and multi-level problem on the specially protected natural territories. The timber business regards the influence of bark beetle as a negative one to the forest, since they destruct spruce stands (and quite often on large areas). Still, the environmental role Bark beetles play in the forest, especially on areas with a primary character, is much more complicated and specific than the simple destruction of spruce stands. Bark beetles exert influence upon the development and formation of stands build up of a complicated composition and structure and they play a role in defining the preservation and formation of communities of living organisms which are ecologically connected to spruce forests. In this way they are an important part in conservation and enriching biodiversity. It is necessary to know and understand the mutual relations and connections that exist between components of the forest ecosystem, which allows us to choose the correct strategy and methods of the struggle with the bark beetle. On specially protected natural territories conservation of biological diversity and conservation of the natural complexes of the whole forest community and its living and dead organisms is the primary goal.
Read more detail on the page "Large-scale cutting of forest infected by Bark beetle (May 2001 - December, 2002)" about how forest ecosystems should be conserved and managed in the right ecological way (including cuttings down), being in the conditions of bark beetle outbreaks on specially protected natural territories .
Forest sites of Belovezhskaya Pushcha suffered from bark beetles are shown in these pictures. These sites are located either in areas which are difficult of access to woodcutters, or the timber is not of great commercial value there. For this reason the primeval wild forest was not cut down there.
Dead trees are an integral and important part of a primeval forest. Furthermore, they create peculiar, primordial and fantastic shapes of this forest which you can see in the photos below.

The advanced international practice and experience with the struggle of bark beetle has often been ignored in Belovezhskaya Pushcha National Park or is under a poor result. Large-scale felling of forest stands affected by bark beetle or lost already is conducted all-the-year-round. The practice of primitive timber-enterprise which results in different ecological violations is often used in protected compartments of Belovezhskaya Pushcha rather than problem-solving. The basic idea of preservation of wild nature, the idea of wild life and proceeding investigations on ecological knowledge and approaches are rejected in this respect as "unwanted".
Nevertheless,some positive tendencies of the right-ecological attitude to the protected forest and friendly-ecological management in bark beetles' centers are outlined last years.
As an example, we demonstrate the same plot of the mixed forest in compartmentå 843 where in 2007 the features of cutting down of living spruce trees were found out in the old and nearly disappeared bark beetle center.
Two spruce trees, still alive but already with obvious attributes of the death after the attack of bark beetles, were found out at the border of the plot - with partially yellowed needles, dead branches at the top and below or the falling off bark. They were not cut down.

The survey carried out half a year later has confirmed that the trees are yet not felled.

The survey carried out one and half a year later has also confirmed that the trees are still preserved in the forest.
Please, pay attention (!) – these spruce trees were still alive but being demonstrated the same attributes of death! It means that even dying trees can be living in conditions of the disappeared bark beetle center during many years but being weakened. This is the best proof of the fact that the treatment of each tree regarding the selection it for felling in a unique and protected forest, such as Belovezhskaya Pushcha, should be very careful and attentive!

Though, it is not inconceivable that woodcutters simply "have forgotten" to cut down these trees two years ago because you can see in the photos below that they were marked as selective for felling. Apparently, it is not economically beneficial repeatedly to come back to take a few individual trees….
