The tool was developed in the, is synthesizing and complementing the knowledge on the effects of woody riparian buffers, and providing online learning tools for the four most important functions
- Nutrient and fine sediment retention
- Water temperature
- Ecosystem services
along rivers impact multiple ecosystem functions through shading and reducing water temperature, retaining nutrients from agricultural areas, providing leaves and wood as food and habitat for aquatic insects and fish, which in turn enhances biodiversity but also increases the recreational value of the river landscape (
Processes supporting these functions and services usually have a spatial connotation and are related to the local woody riparian buffers. However, the processes operate at different lateral scales (e.g. shading mainly depends on trees directly bordering the river while cultural ecosystem services like recreation are provided in the wider context of the valley). Moreover, these local conditions impact downstream sections (e.g. leaves entering locally being washed downstream) and can also connect upstream regions in habitat and migration contexts. Hence the functions operate at different spatial scales, and accordinglyof different width (buffers of fixed width, the whole riparian area and valley floor) and upstream conditions have to be considered.
For each of these four main functions of woody riparian buffers, the relevant spatial scales were identified, knowledge rules developed for the main causal relationships and shown in a conceptual model, which was translated to an interactivefor nutrient retention [ ] and water temperature [ ].
The conceptual models were applied in case-study catchments and results for the present conditions and three futureare presented for each of the four effects.
The results on each of the four functions is summarized and online learning tools available in the four boxes below. In addition,are available.
