Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable biodiversity loss
Abstract Improving our ability to detect changes in terrestrial and aquatic systems is a grand challenge the environmental sciences. In world experiencing increasingly rapid rates of climate change ecosystem transformation, understand predict how, when, where, why occur essential for adapting mitigating human behaviours. this context, long‐term field research infrastructures have fundamentally important role play. For northern boreal landscapes, Krycklan Catchment Study (KCS) has supported...
Abstract Forested riparian buffers are recommended to mitigate negative effects of forest harvesting on recipient freshwater ecosystems. Most the current best practices buffer retention aim at larger streams. Riparian protection along small streams is thought be lacking; however, it not well documented. We surveyed 286 flowing through recent clearcuts in three timber‐producing jurisdictions—British Columbia, Canada (BC), Finland, and Sweden. The jurisdictions differed implementation. In BC,...
Riparian vegetation research has traditionally focused on channel-related processes because riparian areas are situated the edge of aquatic ecosystems and therefore greatly affected by flow regime streams rivers. However, due to their low topographic position in landscape, receive significant inputs water nutrients from uplands. These may be important for vegetation, but role plant diversity is poorly known. We studied relationship between influx groundwater (GW) upland composition along a...
Protecting water quality in forested regions is increasingly important as pressures from land-use, long-range transport of air pollutants, and climate change intensify. Maintaining forest industry without jeopardizing sustainability surface therefore requires new tools approaches. Here, we show how management can be optimized by incorporating landscape sensitivity hydrological connectivity into a framework that promotes the protection quality. We discuss this approach operationalized...
River systems form dendritic ecological networks that influence the spatial structure of riverine communities. Few empirical studies have evaluated how regional, dispersal‐related processes and local habitat factors interact to govern network patterns species composition. We explore such interactions in a boreal watershed show riparian plant richness increases strongly with drainage size, i.e., downstream position network. Assemblage composition was nested, new successively added downstream....
Abstract Groundwater discharge along streams exerts an important influence on biogeochemistry and thermal regimes of aquatic ecosystems. A common approach for predicting locations shallow lateral groundwater is to use digital elevation models (DEMs) combined with upslope contributing area algorithms. We evaluated a topography‐based prediction subsurface zones 1500 m headwater stream reach using temperature water isotope tracers. deployed fiber‐optic distributed sensing instrumentation...
Abstract Traditional approaches aiming at protecting surface waters from the negative impacts of forestry often focus on retaining fixed width buffer zones around waterways. While this method is relatively simple to design and implement, it has been criticized for ignoring spatial heterogeneity biogeochemical processes biodiversity in riparian zone. Alternatively, a variable zone adapted site‐specific hydrological conditions suggested improve protection ecological functions However, little...
Abstract. The riparian zone (RZ), or near-stream area, plays a fundamental role in the biogeochemistry of headwaters. Here, wet, carbon-rich soils can change groundwater chemistry before it enters stream. In boreal forest, RZ an especially important export dissolved organic carbon (DOC) to streams. However, is not uniform, and spatial variability hydrology be large. Terrestrial topographic depressions create hydrological pathways towards focal points RZ, which we refer as “discrete inflow...
Hillslope water is routed through preferential locations in the riparian zone, where its chemical composition can be altered before entering a stream (Ledesma et al., 2018; Lidman, Boily, Laudon, & Köhler, 2017). These are often referred to as zero-order streams, inflows, groundwater seepages, or discharge zones (Kuglerová, Ågren, Jansson, 2014; Meinzer, 1923; Tsuboyama, Sidle, Noguchi, Murakami, Shimizu, 2000). Albeit being frequently used, these terms fail emphasize dynamic hydrological...
Riparian buffers are the primary tool in forest management for protecting habitat structure and function of streams. They help protect against biogeochemical perturbation, filter sediments nutrients, prevent erosion, contribute food to aquatic organisms, regulate light hence water temperature, deadwood, preserve biodiversity. However, production forests Sweden Finland, many headwater streams have been straightened, ditched, and/or channelized, resulting altered hydrology reduced natural...
Abstract Generally, governments and industry have implemented some degree of protection to reduce the impacts forestry on aquatic ecosystems. Here, we consider widespread application streamside management in terms riparian buffer retention protect freshwaters from practices across three jurisdictions with large intensive sectors (British Columbia, Finland Sweden). This perspective was developed by working researchers, practitioners policymakers mitigation measures decrease streams. We...
Abstract Clearcutting increases temperatures of forest streams, and, in temperate zones, the effects can extend far downstream clearcut itself. Here, we studied whether similar patterns are found colder, boreal and if riparian buffers prevent stream water from heating up. We recorded temperature at 45 locations across nine streams with varying buffer widths. In these compared upstream (control) reaches clearcuts up to 150 m immediately clearcut. summer, daily maximum 4.1°C, warmest week...
Abstract Riparian habitats are highly susceptible to invasion and the spread of non‐native plants. Many freshwater organisms processes dependent on allochthonous subsidies, thus, riparian invasions often associated with changes in aquatic ecosystems. We studied potential effects plant instream decomposition detritivore communities. compared rates ( k ) leaf litter from species native invasive coastal British Columbia, macroinvertebrate assemblages local novel resource subsidy.

In this paper we describe how forest management practices in Fennoscandian countries, namely Sweden and Finland, expose streams to multiple stressors over space time. region, forestry includes several different actions explore these may successively disturb the same location 60–100 year long rotation periods. Of actions, final harvest associated road construction, soil scarification, and/or ditch network maintenance are most obvious sources of aquatic ecosystems. Yet, more subtle such as...
Riparian buffers are commonly used to mitigate the negative effects of forestry operations near water, particularly sediment transport streams. In Sweden, current practices typically involve 5-7 m wide riparian along small Historical forest management, which favored conifers up channel edge, has resulted in these narrow having a simplified tree species composition and structure, making them prone windthrow. While windthrow can contribute large wood (LW) streams, also risks increasing inputs...
