Tutkimuksessa selvitettiin prosessimallinnukseen ja kokeellisiin tutkimuksiin perustuen jatkuvan kasvatuksen ja tasaikäismetsätalouden vaikutusta metsäisiltä valuma-alueilta tapahtuvaan typpi- ja fosforikuormitukseen. Laskennan perustana oli, ett

Many recent studies have indicated upward trends in carbon and nutrient concentrations from drained peatland forests over time since their initial drainage, but the mechanisms behind these trends are still poorly understood. We gathered data on nitro

Half of the Finnish peatland area is drained for forestry. The remaining undrained peatlands are not all pristine, because surrounding drainage may disturb their hydrology. This concerns especially aapa mires, which are dependent on hydrological conn

1. Growing bioeconomy is increasing the pressure to clear-cut drained peatland forests. Yet, the cumulative effects of peatland drainage and clear-cutting on the biodiversity of recipient freshwater ecosystems are largely unknown. 2. We studied the i

Spatiotemporal information on historical peatland drainage is needed to relate past land use to observed changes in catchment hydrology. Comprehensive knowledge of historical development of peatland management is largely unknown at the catchment scal

Highlights • Streams in Fennoscandian production forests are subject to number of disturbances. • Operations during the forestry rotation cycle introduce stressors to small streams. • Individual stressors interact in time and space causing mult

Contradictory results for the long-term evolution of nitrogen and phosphorus concentrations in waters discharging from drained peatland forests need reconciliation. We gathered long-term (10–29 years) water quality data from 29 forested catchments,

Highlights • Nutrient and SS estimations were predicted by comparing different approaches. • Peatland drainage strongly affected TN, TP, and SS loads and concentrations. • Uncertainty in estimates captured 29–90% of measured TN, TP, and SS va

Highlights • N, P and TOC export from forests to streams needs more reliable assessments. • Long-term data were used to assess export at different spatial scales in Finland. • N, P and TOC concentrations increased with temperature sum, i.e. fro
