“…A prominent reason for this is the divergent interpretations that have arisen shortly after the publication of Tüxen's concept. Maps that aimed at reconstructing pre-human or potential natural vegetation were produced in many countries or regions (e.g., Küchler 1964;Scamoni and Grosser 1964;Zólyomi 1967;Mikyška et al 1968Mikyška et al -1972Falińsky 1977;Michalko et al 1986). However, reconstructed vegetation and PNV maps were not clearly distinguished.…”

“…However, reconstructed vegetation and PNV maps were not clearly distinguished. For several of the countries, reconstruction of past vegetation without human disturbance, i.e., pre-human vegetation, were carried out (e.g., Zólyomi 1967;Mikyška et al 1968Mikyška et al -1972Michalko et al 1986). Some of them were correctly named reconstructed vegetation maps, while others were labelled geobotanic maps or maps of the natural vegetation.…”

Background: The concept of potential natural vegetation (PNV) embodies mature vegetation capable to survive under the environmental conditions of a site. Despite its widespread use, its applicability under the current level of human impacts on the environment has been criticised. Aims:We re-examine the original publication of the PNV concept and its development over time to identify the sources of tension between theory and application and to direct the discourse onto a common ground of understanding. Our focus is the relationship between human impacts and PNV.Arguments: Based on extended excerpts and detailed interpretation, we affirm that PNV applies to a specific point in time. Consequently, it is independent of any realised vegetation including past undisturbed (pre-human) vegetation. We track possible routes and reasons for alternative interpretations. We identify PNV as a mental concept, a neutral model, that represents baseline vegetation potential that excludes contemporary human management but includes past environment modifying impacts. We address how a concept reflecting unmanaged vegetation can be important for application in a world transformed by humans. Conclusions:Rather than abandoning the concept, we advocate adhering to using it in the original sense of its definition. This way PNV can serve research as a neutral model and support sustainable land use planning.

Context. Understanding biota distribution patterns and diversity within fragmented urban environments is essential for effective conservation and management. Objectives. The objective is to explore the impacts of fragmentation on plant and mollusc communities by examining their diversity and community composition in isolated urban forests and continuous forest stands along urban-rural gradients. The study aimed to explore plant and mollusc diversity variation across the urban-rural gradient in various landscape categories such as forest islands, peninsulas, and contiguous (control) stands and determine the responsible environmental drivers. Methods. The study surveyed 30 plots in Bratislava City, Slovakia, to evaluate the species richness and density of vascular plants and terrestrial gastropods in different landscape categories (see above); we also utilised microclimate data from selected plots. Results. The islands exhibited the highest number of non-native gastropod and plant species, whereas the control plots showed the lowest. Additionally, the forest islands were identified by an increased soil pH, coarse woody debris and litter content, enhancing the species richness of plants and molluscs. GLMs demonstrate that the landscape category had the most notable impact on the diversity of plants and molluscs. While fragmentation characteristics had an impact on the composition of plant species, they did not have a significant effect on the composition of molluscan communities. Conclusions. The research underlines the significance of landscape categories, environmental factors, and fragmentation characteristics when assessing biodiversity in urban forests. This finding can be used to formulate effective strategies for protecting native biota in fragmented urban forests.

Based on the geological and hydrogeological conditions, and in situ hydrogeological tests of the emergency groundwater source in Nantong City, China, a 3D numerical model of the heterogeneous anisotropy in the study area was established and calibrated using data from pumping and recovery tests. The calibrated model was used to simulate and predict the water level of the depression cone during the emergency pumping and water level recovery. The results showed that after seven days of pumping, the water level in the center of the depression cone ranged from −51 m to −55 m, and compared with the initial water level, the water level dropped by 29 m to 32 m. The calculated water level has a small deviation compared with that of the analytical solution, which indicates the reliability and rationality of the numerical solution. Furthermore, during water level recovery, the water level of pumping wells and its surroundings rose rapidly, which was a difference of about 0.28 m from the initial water level after 30 days, indicating that the groundwater level had recovered to the state before pumping. Due to the emergency pumping time is not long, the water levels of Tonglu Canal, surrounding residential wells, and other aquifers will not be affected. After stopping pumping, the water level recovers quickly, so the change of water level in a short time will not lead to large land subsidence and has little impact on the surrounding environment.
