Fluvial landscapes are one with the highest capacities of ecosystem services. Ecosystem services are ecological characteristics, functions, or processes that (in)directly contribute to society’s wellbeing (Costanza et al.,1997). For example, the river provides freshwater, fish, or materials. This fact has been known for centuries as people settled around rivers and profited from their benefits. However, today’s rivers are under anthropogenic pressure. Therefore, the provided ecosystem services can be limited due to the degradation of the channels. We focussed on two contrast fluvial corridors located in the Odra and the Ostravice rivers, with the aim to i. map their general ecosystem services, ii. to highlight differences between them, and iii. to reveal ecosystem services of large wood that occurred in both localities but different spatiotemporal patterns. Both studied reaches are located in the city of Ostrava, in the Moravian-Silesian region, Czechia.
