The results of three years mycological observations, a part of the Czech-Italian-Polish joint project "Mycological monitoring in European oak forests" (Perini, Ławrynowicz and Fellner 1995), are presented in the paper. The Ińsko Landscape Park is the most northerly situated locality investigated in this project. The macrofungi were studied in the <i>Stellario-Carpinetum</i> association on two plots (1000 m<sup>2</sup> each:I - with <i>Quercus petraea</i> snd II - with <i>Qu. robur</i>. The collection of 229 species (157 saprotrophes and 72 mycorrhizal ones) is the subject ofe ecological analysis. Among the collected fungi 9 species associated with oak were distinguished as well as 12 threatened species and l species new to Poland.

Climate change may foster pest epidemics in forests, and thereby the fluxes of elements that are indicators of ecosystem functioning. We examined compounds of carbon (C) and nitrogen (N) in insect faeces, leaf litter, throughfall and analysed the soils of deciduous oak forests ( Quercus petraea  L.) that were heavily infested by the leaf herbivores winter moth ( Operophtera brumata  L.) and mottled umber ( Erannis defoliaria  L.). In infested forests, total net canopy-to-soil fluxes of C and N deriving from insect faeces, leaf litter and throughfall were 30- and 18-fold higher compared with uninfested oak forests, with 4333 kg C ha −1 and 319 kg N ha −1 , respectively, during a pest outbreak over 3 years. In infested forests, C and N levels in soil solutions were enhanced and C/N ratios in humus layers were reduced indicating an extended canopy-to-soil element pathway compared with the non-infested forests. In a microcosm incubation experiment, soil treatments with insect faeces showed 16-fold higher fluxes of carbon dioxide and 10-fold higher fluxes of dissolved organic carbon compared with soil treatments without added insect faeces (control). Thus, the deposition of high rates of nitrogen and rapidly decomposable carbon compounds in the course of forest pest epidemics appears to stimulate soil microbial activity (i.e. heterotrophic respiration), and therefore, may represent an important mechanism by which climate change can initiate a carbon cycle feedback.

Natural Stands

This research was carried out in natural stands of sessile oak (Quercus petraea agg. Ehrendorfer 1967) on Miroc mountain. Three comunities were investigated: Pure sessile oak forest (Quercetum montanum Cer. et Jov. 1953. s.l.), sessile oak-common hornbeam forest (Querco-Carpinetum moesiacum Rud. 1949. s.l.) and sessile oak-balkan beech forest (Querco-Fagetum Glis. 1971). Pure sessile oak forests are found on the following soils: dystric ranker and acid cambic soil on sandstone, dystric ranker and acid cambisols on phyllite, and acid cambic soil on schists. Sessile oak-hornbeam forests grow on sandstone, granite and schists. Sessile oak-beech forests are found on acid cambisol on phyllite and sandstone conglomerate. Various ecological conditions (exposition, slope, altitude, soil types and bedrock) on Mt Miroc caused the occurence of diverse sessile oak forest communities, while different states of these forest stands resulted from the implementation of management measures.

Mycosociological observations were carried out between 1994-1996 on permanent plots within a <i>Tilio-Carpinetum</i> association in the Białowieża National Park. The project was carried out with international cooperation within the "Mycological monitoring in European oak forests" programme which was a result of multiple signals concerning the disappearance of oaks in our continent. Almost 40 years before mycosociological research in the same plant association and at the same plots were carried out. Studies were mainly concerned with analysing the terrestrial macromycetes, predominantly <i>Boletales</i> and <i>Agaricales</i>. They analysed the occurrence of saprotrophic and mycorrhizal fungi. Totaly 215 species from the above listed ecological groups, but there were only 34 species common to both studies. Dominating species within the mycorrhizal group were found.
