Our aims were to examine, parallel to their phenology, the stand level Net Ecosystem CO2 Exchange (NEE) and evapotranspiration (ET) fluxes as well as the dependence of NEE on leaf area (LA), air temperature (Tair) and light (PPFD) in three spring forest geophytes that are widespread in Europe. Furthermore, we compared the leaf and stand level net photosynthesis. The methods used included open chamber measurements with an infrared gas analyser in permanent plots on a weekly basis. The results showed that the stand levels of all three species proved to be carbon sinks from the beginning of the vegetation period until the end of it or until the last phase of fruit formation. The largest amount of carbon sink was observed at the peak of blooming. A positive linear correlation was measured between NEE and PPFD as well as between NEE and LA, while a negative linear regression was measured between NEE and Tair. The remarkable carbon uptake capacity indicates the non-negligible role of geophyte vegetation in the carbon flux of temperate forests. In addition, the research provided new proof about the role of stand level operation, stability and regulation.

However, most of these do not focus on woody species, and few examine the entire annual phenological cycle of woody species. In this paper, we explore the phenological pattern of seven woody species native to Europe under ex situ conditions for 3 years, in two urban areas with different mesoclimates. The average temperature differs by 1.81 °C between the two sites. The investigated plants were clonally identical for each species, and the exact same care protocol was kept at both sites. Despite the large variation in the phenological pattern between years, during the study, spring phenophases occurred earlier, while the examined autumn phenophases were delayed at the site observing a higher average temperature. The phenological sensitivity of flowering was significantly higher than that of leaf bud burst. The growing season was 14.8 days longer at the site with a higher average temperature. In most cases, a significant correlation was obtained between the examined phenophases and climatic factors at both sites. Among the autumn phenophases, the strongest correlation was found between the maximum temperature between July and October and the beginning of leaf coloring.

Here, the soil seed bank of a wet grassland type, an ecotone and a semi-dry grassland type, all formed along a slope in NE Hungary, were compared from the aspect of recovery potential. For this, a vegetation survey and a seedling emergence examination were performed. The seed banks of the three grassland types differed significantly in terms of density. It was significantly higher in both the wet and the ecotone grassland types than in the semi-dry one. The seed banks of the three grassland types proved to be very similar in terms of diversity. The floristic similarity between the vegetation and the seed banks was much higher in both the wet and the ecotone grassland types than in the semi-dry one. Most of the abundant species of the vegetation had transient seed banks, but more of the characteristic species of the wet and the ecotone grassland types maintained dense and/or persistent seed banks than those of the semi-dry one. In the case of degradation, a complete recovery is not ensured by the seed bank of either studied grassland type; however, compared to that of the semi-dry grassland, the wet grassland’s seed bank better supports an increase in diversity within a limited period. In the case of restoration, within five years after destruction, it could be more rewarding to deal with wet grassland types prior to dry ones.
