Abstract
Based on data from 12 microclimate measurement networks placed in different gaps of various forest stands in Hungary, linear correlation was found between the gap size and certain daily meteorological parameters. The comparison of the forest and gap data to the nearest state meteorological observatory also revealed systematic differences. These provide opportunity to estimate certain climatic parameters, e.g. daily maxima or minima in various sized gaps and the surrounding forest stand, based on standard meteorological observations. Relationship between attributes of 109 gaps and species diversity were analysed as well as indication of microclimatic gradient by regrowth species. Effect of gap age and size are different by social behaviour type. The shape of gaps affects the species richness of regrowth. Positive correlation was detected between Forest Aridity Index and diversity variables. The total number of species, individuals and effective numbers of regrowth species are highest in the centre of the gaps. Shady, moist areas of gaps are indicated by regrowth of typical mesophilous tree species.
