There are seven zonal forest plant communities in Bosnia and Herzegovina. As zonal vegetation is regarded as a large-scale expression of macro-climate, using data from Bosnia and Herzegovina, we aimed to reveal whether macro-climate is indeed the most important factor determining the existence of zonal forest plant communities. In addition, we wanted to find out if zonal communities would demonstrate similarities in Grime’s ecological (CSR) strategies. Ordination revealed that the species turnover between the zonal communities is strongly correlated to the macro-climatic gradient (annual mean temperature, mean temperature of the coldest quarter and precipitation of the warmest quarter), while no correlation with topographic factors (slope and aspect) and soil reaction was detected. Functional analysis of all layers showed that competitive ecological strategy has the highest proportion, while analysis of the herb layer alone expressed a shift of CSR signatures towards the middle of the C–S axis. Ruderality was overall poorly expressed. Statistically significant differences between communities were discovered along the C–S axis. Our study confirmed that macro-climatic gradient is the most important determinant of the species turnover along zonal forest plant communities. CSR signatures showed that zonal forest vegetation is represented by productive communities in a terminal stage of succession.
