Facts about intelligent bufferzones

Establishment of bufferzones provides multifunctionality with large potential benefit for nature, environment and production (Kronvang et al. 2010; Stutter et al. 2012). If bufferzones are placed and modified to local conditions, a range of benefits for nature and environment can be achieved. At the same time, it is possible to harvest the biomass in order to make profit and reduce nutrients from the soil in the bufferzone.

The following figure shows an illustration of a stream with its 9 meter buffer zone, which is the situation today (top) and an intelligent use of a bufferzone (bottom).

There are two types of bufferzones, as seen in the figure:
1.The dry peripheral zone that can be established with varying width along streams depending on terrain and local conditions. The vegetation can vary from landscaped or natural vegetation to trees.
2.The wet rim zone is established by altering the hydrology (groundwater) either by changing watercourse maintenance or by allowing drainage water to seep through a wet zone (for example, an established ditch) along the stream.
