Peatlands worldwide are being threatened by intensive land use and drainage, which leads to soil subsidence. This has consequences for farming, especially on low-gradient cultivated peat-dominated lowlands with high flood risk. In this study, we combined historical elevation data new lidar improve the estimation of subsidence its lowland river systems. The results showed 202−349 mm within last 24–51 years, a mean rate 5.15–9.47 y−1 riparian peatland west coast Finland. was partly explained...
Peatlands have been degrading globally, which is increasing pressure on restoration measures and monitoring. New monitoring methods are needed because traditional time-consuming, typically lack a spatial aspect, sometimes even impossible to execute in practice. Remote sensing has implemented monitor hydrological patterns impacts, but there of studies that combine multi-sensor ultra-high-resolution data assess the hydrology peatlands. We optical, thermal, topographic unmanned aerial vehicle...
Peatland restoration aims to achieve pristine water pathway conditions recover dispersed wetness, quality, biodiversity and carbon sequestration. Restoration monitoring needs new methods for understanding the spatial effects of in peatlands. We introduce an approach using high-resolution data produced with unmanned aircraft system (UAS) supported by available light detection ranging (LiDAR) reveal hydrological impacts elevation changes peatlands due restoration. The were assessed analyzing...
Remote sensing (RS) can be an efficient monitoring method to assess the ecological impacts of restoration. Yet, it has been used relatively little monitor post‐restoration changes in boreal forestry‐drained peatlands, and particularly linkages between RS plant species remain vague. To understand this gap, we utilize data from Finnish peatland restoration network spanning 150 sites a 10‐year period. We employ Bayesian joint distribution models (Hierarchical Modeling Species Communities) study...
Remote sensing (RS) has been suggested as a tool for peatland monitoring. However, there have only few studies in which post-restoration hydrological changes quantified with RS-based modelling. To address this gap, we developed an approach to assess spatiotemporal the water table (WT) optical Sentinel-2 and Landsat imagery. We tested eleven northern boreal peatlands (six restored, five control sites) impacted by forestry drainage Finland using Google Earth Engine cloud computing...
In Finland over half of the mire habitat types are endangered mainly due to drainage-induced succession towards more forested type ecosystems. Restoration is thought be an important tool improve status degraded peatlands. National and European Union level strategies nature conservation have a target increasing allocation restoration actions peatlands in Finland. Thus, effects peatland need understood.Peatland drainage lowers water table exposes peat decomposition. aims raise table, but it...
Most northern peatlands are severely degraded by land use and drainage. Peatland restoration is an effective way to return the natural functions of in catchment hydrology, discontinue peat degradation re-establish long-term carbon sinks. The main aim rewetting direct water flows back pristine routes increase water-table levels. Conventional monitoring methods such as stand-pipe wells typically limited sparse locations cannot give a spatially representative overview.We introduced novel...
