Water chemistry in 179 randomly selected Swedish headwater streams related to forest production, clear-felling and climate
From a policy perspective, it is important to understand forestry effects on surface waters from a landscape perspective. The EU Water Framework Directive demands remedial actions if not achieving good ecological status. In Sweden, 44 % of the surface water bodies have moderate ecological status or worse. Many of these drain catchments with a mosaic of managed forests. It is important for the f...
متن کاملRelationship between structural features and water chemistry in boreal headwater streams—evaluation based on results from two water management survey tools suggested for Swedish forestry
Forestry may cause adverse impacts on water quality, and the forestry planning process is a key factor for the outcome of forest operation effects on stream water. To optimise environmental considerations and to identify actions needed to improve or maintain the stream biodiversity, two silvicultural water management tools, BIS+ (biodiversity, impact, sensitivity and added values) and Blue targ...
متن کاملThe Role of Headwater Streams in Downstream Water Quality1
Knowledge of headwater influences on the water-quality and flow conditions of downstream waters is essential to water-resource management at all governmental levels; this includes recent court decisions on the jurisdiction of the Federal Clean Water Act (CWA) over upland areas that contribute to larger downstream water bodies. We review current watershed research and use a water-quality model t...
متن کاملForest age, wood and nutrient dynamics in headwater streams of the Hubbard Brook Experimental Forest, NH
Instream processing may substantially alter nutrient export from forested watersheds. This study tested how instream uptake of N and P were affected by successional differences in the accumulation of large wood and debris dams in a 66-year chronosequence formed by five watersheds within the Hubbard Brook Experimental Forest (HBEF), NH. Nutrient enrichment releases in summer 1998 were used to me...
متن کاملConditions in Agricultural Headwater Streams
11 Whilst the processes involved in the cycling of dissolved phosphorus (P) in rivers have been 12 extensively studied, less is known about the mechanisms controlling particulate P concentrations 13 during small and large flows. This deficiency is addressed through an analysis of large numbers of 14 suspended particulate matter (SPM) samples collected under baseflow (n = 222) and storm event (n...
