Alternative label Montane areas Definition Targeted planting of forests in headwater areas (e.g. with a slope) can help to stabilize hillslopes, thereby reducing erosion and potentially leading to greater water retention in montane areas. Afforestation may have beneficial effects on the hydrograph by reducing peak flows and helping to maintain base flows. The potential for water retention must be balanced against the increased ET and pollutant trapping that may be associated with forests. - Based on Stella definitions, adapted by NWRM project experts and validated by the European Commission Links Relation type Narrower Concept Natural Water Retention Measure External links Themes forestry Type of action Afforestation Biophysical benefits Decrease of runoff Decrease of erosion
