Lasy są dynamicznym tworem przyrody (i człowieka). Odpowiedzialność za nie spoczywa na całym społeczeństwie.

The Bulletin of the Polish Academy of Sciences: Technical Sciences (Bull.Pol. Ac.: Tech.) is published bimonthly by the Division IV Engineering Sciences of the Polish Academy of Sciences, since the beginning of the existence of the PAS in 1952. The journal is peer‐reviewed and is published both in printed and electronic form. It is established for the publication of original high quality papers from multidisciplinary Engineering sciences with the following topics preferred: Artificial and Computational Intelligence, Biomedical Engineering and Biotechnology, Civil Engineering, Control, Informatics and Robotics, Electronics, Telecommunication and Optoelectronics, Mechanical and Aeronautical Engineering, Thermodynamics, Material Science and Nanotechnology, Power Systems and Power Electronics.

Na czym polega proces rozkładu ściółki leśnej i jakie jest jego znaczenie dla ekosystemów leśnych? Czy w nadchodzącej przyszłości ciągle aktualne będzie stare powiedzenie: „Nie było nas, był las, nie będzie nas, będzie las”?

Aktualnym wyzwaniem dla leśników jest znalezienie sposobów na przebudowę polskich lasów, by dostosować ich skład gatunkowy do zmieniających się warunków siedliskowych.

The herbaceous understory is the lowest, ground-level layer of plants and fungi in the forest. What is its role and importance in the main ecological processes occurring in forest ecosystems?

What makes forest litter so important? How rapidly does it decompose? And how can it contribute to mitigating the effects of climate change?

The current challenge for Polish foresters is to properly reshape our forests, adapting the species composition to the changing habitat conditions.

Woda jest niezbędna do wzrostu i rozwoju roślin. Jej ilość decyduje o tym, jak wyglądają ekosystemy poszczególnych stref klimatycznych. Jak niedobór i nadmiar wody wpływają na szatę roślinną różnych obszarów świata i Polski?

Water is essential for plant growth and development, and the degree of its availability significantly shapes ecosystems in different climate zones. How does an overabundance or deficiency of water affect the flora in Poland and different parts of the world?
