Abstract Small water bodies play a specific role in the landscape, as they increase the mosaic pattern of a given area, retain water and affect hydrological regime in adjacent soils. These water bodies are the most important in landscapes that have been largely transformed by man, such as agricultural and urban landscapes. The author of this study assessed the ecological status of small water bodies using the Q index and determined the impact of the development of adjacent areas on their ecological status. The analysis of the Q index referring to water bodies showed that its values changed considerably not only during the whole study period but also during one year (from 1.74 to 4.28). The land use analysis in the designated buffer zones stretching within 500 m and 1000 m from the water bodies showed that arable land occupied the largest area. This fact determines the ecological status of these water bodies. Ecotones that develop around ponds can function as biogeochemical barriers reducing pollution in the area. A total of 116 species of vascular plants were identified in the water bodies under study. Herbaceous plants constituted the largest group – 87 species. Trees and shrubs were represented by 16 species and macrophytes by 16 taxa.
