Manor parks are characteristic objects in the agricultural landscape of Poland. Lack of proper management after World War II, however, led to their devastation from a cultural point of view, but may allow the regeneration of rare and endangered species. The aim of our study was to determine if the presence of forests in the vicinity of manor parks will work as an accelerator of the regeneration process of oak-hornbeam and ancient forest species. Phytosociological analyses were conducted in manor parks adjacent to forests and not adjacent to the forest as well as natural forests. The total number of plant species, number and percentage share of ancient forest species, and plant species consistent with oak-hornbeam habitat were analyzed using a GLM model. Characteristic species were identified using detrended correspondence analysis. Parks adjacent to forests and natural forests showed higher numbers of total species, ancient forest species, and oak-hornbeam species compared with parks not adjacent to forests, but there were no differences in percentage shares of ancient forest species and oak-hornbeam species. For all three types of studied objects, characteristic species could be identified. We conclude that adjacent forests allow greater regeneration of ancient forest species and oak-hornbeam forest species in manor parks.

AbstractThis study investigates how methodological aspects of seed-bank sampling affect seed-bank records in temperate deciduous forests. We focused explicitly on seed-bank records of ancient forest species, which are assumed to lack a persistent seed bank; a hypothesis suspected to be partly due to methodological shortcomings. Through a quantitative review of 31 seed-bank studies in temperate deciduous forests of central and north-west Europe, we quantified the role of sampling methodology in constraining total seed-bank records and seed-bank records of ancient forest species (γ-diversity, average species' retrieval frequency and average seed density). A major methodological trade-off was established between sampled plot area and the number of plots: at an increased number of plots, the area sampled per plot decreased significantly. The total surface area sampled in a study was the primary determinant of γ-diversity, both for overall species richness and for ancient forest species richness. A high retrieval frequency of ancient forest species indicated that few plots were intensively sampled. The parallel increase in total species richness and ancient forest species richness and the non-significance of their ratio in relation to methodological variables suggests that ancient forest species are not particularly rare in the seed bank compared to other species. These results imply that sampling methodology has a far-reaching impact on seed-bank records such as γ-diversity, the detection of ancient forest species and ultimately seed-bank composition. We formulate a set of guidelines to improve the quality of seed-bank studies in temperate deciduous forests.
