The paper presents sedimentary records acquired as part of the research on the coastal cliff located between 221.3 and 221.4 km of the Slovincian (Słowinskie) Coast near Debina. Palynological and subfossil Cladocera analysis of sediments combined with geochemical data proves the existence of varying environmental conditions that occurred depending on the climate fluctuation. The Debina reservoir was formed in the Late Glacial period. Mud and gyttja were deposited in an initially cold proglacial lake. Species of Cladocera identified in this period indicate a deeper oligotrophic reservoir. The end of the Late Glacial cooling inhibited the development of fauna in the reservoir. Climate change at the beginning of the Holocene improved the habitat conditions in the Debina paleolake, which is reflected in the growth of zooplankton biodiversity and enrichment of the aquatic pollen content. We distinguished three phases that illustrate the evolution of the studied aquatic-mire ecosystem. In the following periods, the trophic level in the reservoir increased and significant water-level fluctuations led to periodic transformations of reservoirs into peat bogs. Gradually, the water-level lowering and the intensification of eolian processes led to terrestrialization of the paleolake.

The paper presents the results of a questionnaire carried out among landscape users in Suwałki and Augustów Region concerning the perception of goods of nature. Respondents were asked to assign services to 7 ecosystem types (deciduous forest, coniferous forest, swamp forest, grasslands, croplands, wetlands, water bodies) and rank them in order of importance. Our intention was to show the potential/capacity of each ecosystem type to deliver four cultural ecosystem services: sport and recreation, inspiration for creative work, education and science and spiritual experience in the view of local community and tourists.

The general objective of the study was to present different methods for identification and assessment of ecosystem services provided by various ecosystems in postglacial landscape. Our study focused on ecosystem-oriented approach in which the potential of ecosystems to deliver goods and services was analyzed. Other approaches, e.g. society-oriented (dealing with goods and services demands) or process-oriented (focused on uptake of goods and services) were applied only additionally.

W niniejszym artykule zaprezentowano wyniki badań nad przestrzennym zróżnicowaniem potencjału ekosystemów do dostarczania wybranych usług zaopatrzeniowych i regulacyjnych. Każde z wybranych do prezentacji świadczeń (cztery usługi zaopatrzeniowe – plony zbóż, miód, biomasa zwierząt kopytnych, zapas drewna na pniu; jedna usługa regulacyjna –sekwestracja węgla w glebie) jest przykładem innego podejścia do definiowania i obliczania wskaźników określających potencjał do świadczenia usług. Wyniki zróżnicowania przestrzennego potencjałów przedstawiono na mapach, obejmujących trzy gminy z Polski północno-wschodniej.

Nonetheless, to date, there has been rather a small number of scientific papers which verified in a comprehensive manner the methodological assumptions of the ES concept as a conglomerate of material and non-material benefits derived by human from natural environment and cultural heritage. Such scientific approach to ES concept has been adopted and implemented in the project “Ecosystem services in young glacial landscape – assessment of resources, threats and use” supported by National Science Centre (2012/07/ B/ST10/04344), carried out in Institute of Geography and Spatial Organization, Polish Academy of Sciences since 2012. This article presents the project objectives, assumptions and research methodology.
