Abstract
The paper analyses three forest types belonging to the following associations: (1) fresh pine forest (Peucedano-Pinetum), (2) mixed pine forest (Querco roboris-Pinetum) and (3) oak-hornbeam forest (Tilio cordatae-Carpinetum betuli). They are located in north-eastern Poland. We compared the indicator value of three sets of data:(1) phytosociological relevés representing ancient forests (each type/association), (2) phytosociological relevés representing the youngest recent forests with the shortest regeneration period (each type/association) and (3) the ‘abstract pattern’ (representing the core of a specific type of plant community with a characteristic combination of species and clearly representing a separate type of ecosystem/association). Three sets of data together with their indicator values/numbers: light intensity (L), soil moisture (F), soil reaction (R), and nitrogensupply (N) according to the Ellenberg scale, constituted the basic material for comparative indicator analysis. The percentage shares of ecological groups of species have been calculated as well as the average indicator values for each of these within a data set. The results obtained show that the ‘abstract pattern’ can be treated as a good measure for the evaluation of ancient forest habitat conditions; it is clearly visible in the mean L and F indicator values of the Peucedano-Pinetum and Querco-Pinetum associations, and also in the N of Peucedano-Pinetum and R of Querco-Pinetum, which are closer to ancient forest than to recent forest. In all cases, we found ecological differences between the ancient and recent forests based on their indicator values. Statistically significant differences of the mean L indicator values between ancient forest and recent forest have been found in three types of forest community.

Abstract
Presented here are the means of generating and possibilities for applying a digital map of sequences of ‘forest/non‑forest’ states in a study area, as based on topographic maps for seven instances in time (between 1800 and the present day). There is also a brief description of cartographic material used, as well as the methods applied in generating a variability model. The study area was then analysed from the point of view of differences in the aforementioned sequences of ‘forest/non‑forest’ states, this revealing marked contrasts between two Polish regions that are adjacent, but were conditioned differently in the past, in political and social terms. The study ends by considering the relationship between the distinguished sequences and habitat type, as referred to in terms of potential natural vegetation.

Abstract
This paper presents: (1) a method by which to forecast future states of ecosystems onthe basis of deterministic models of development pathways, (2) necessary data to achieve this,and (3) an application of the above method to Poland’s Bory Tucholskie National Park. The threerequired datasets to predict vegetational states were a complex digital map of potential 1 and actualvegetation, scenarios concerning future anthropogenic impacts on vegetation and habitats,and general models of vegetation development. The chosen study area is shown to feature processesof vegetation transformation, such as degeneration, regeneration, restitution, succession,slow evolution from type to type, stabilization and fluctuation. The three scenarios applied entailed:(1) the development of plant communities in conditions of a stable habitat and persistenthuman impact; (2) fully spontaneous 2 development of vegetation in unchanged habitats and freeof human impact; (3) full achievement of a conservation plan’s recommendations. The resultsof modelling future states of vegetation show that regeneration and evolution will prevail as aresult of the first and second scenarios, resulting in noticeable changes in spatial and typologicaldiversity of vegetation, whilst regeneration and stabilization will be dominant processes accordingto the third scenario.

Abstract
This paper concerns the relationships between potential natural vegetation and geomorphologicalforms. The study area covers a fragment of the Vistula river valley for which unitsof potential vegetation were identified and a digital vegetation map constructed. Correlations betweenthe potential natural vegetation and geomorphological forms were analyzed, and generalconclusions drawn in regard to the geomorphology of the valley (beyond the range of the detailedmap). Some changes to the general map have also been proposed and a hypothesis on the presenceof an ‘island’ of Pleistocene deposits within the Holocene valley advanced.
