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 demonstrate that it is exceedingly rare for policies guidelines specify concrete objectives measurable targets can be assessed against outcomes. Most often, policy prescribe ‘to prevent or mitigate impacts’, this vagueness insufficient our waters. argue should clearer about (outcomes) go beyond simple idea presence, without further specification its conditions, always a successful strategy. One cannot measure effectiveness rules quantitative targets. Policy implications : In paper, suggest locally adjusted buffers must include quantifiable, goals what supposed achieved protected respect ecological functions, biological communities other values. It relatively move current vague such as ‘protect prevent’ defined range values parameters are provide. For example, these region‐specific shading levels microclimate targets, wood volumes, forest species composition. stress through an open dialogue between agencies, practitioners, land owners scientists. acknowledge there trade‐offs being too prescriptive vague. However, when excessively broad norm, lose capacity effectively implement, monitor evaluate outcomes measures.

Abstract Questions The River Continuum Concept (RCC) predicts a gradual shift of functional adaptations organisms along the longitudinal (upstream–downstream) gradient, as well maximization biotic diversity in mid‐reaches. Although this theoretical framework was originally developed for stream macroinvertebrates, we tested whether such pattern can also be observed riparian plant communities. Location study conducted upper catchments San and Wisłoka Rivers southeastern Poland. In both catchments, very preserved forests occur continuously rivers. Methods We studied cover species across two river networks. analyzed taxonomic indices, community‐weighted means traits relation to plots' positions catchments. Results richness divergence displayed unimodal patterns increasing values were similar, but some plots lowest reaches more diverse than expected, forming an additional increase diversity. largely line with predictions RCC. discovered significant decrease specific leaf area height herbaceous plants communities gradient.

We carried out randomized, plot‐based vegetation survey of systematically sampled 500 m‐long sectors along the whole river, dividing zone into two internal external strips. From historical aerial photos, within plots were detected classified age classes: (i) cut 8 years (recent); (ii) between 19 ago (intermediate); (iii) no signs last (distant). analyzed responses to strip position. Alien species richness was higher woody lower recently clear‐cut areas compared those with distant event. Moreover, woods had more alien synanthropic species. Intermediate levels invasion by cut. Riparian strips are impacted clear‐cutting, but seem recover 8–19 thanks their natural resilience. Conversely, recent or intermediate did not affect any investigated attributes since such already invaded after human disturbance. Our results confirm that can effects confirming vulnerability ecosystems suggesting need for caution management practices improve conservation status forests.

Riparian wetland ecosystems provide important ecological services but are also vulnerable to climate change and human activities. To understand the influence of natural factors (e.g. change, flooding, drought) activities agriculture) as well support management strategies, reconstructions past vegetation environmental changes needed. achieve this, we conducted a multi-proxy paleoecological analysis, including pollen spores, macro-charcoal radiocarbon dating, on sediment core taken from riparian area in Harapan forest Sumatra. Three distinct periods were identified: i) AD 1100 – 1400: Upland swamp with herbaceous vegetation, possibly part buffer zone riverbank), was present study under stronger dry season regime; ii) 1400 1870: freshwater swamps expanded site; iii) later, 1870 present, upland forests dominated strong season.

Then, HEC–RAS 2D modelling was analyse Further also created predict (i) invasive plant control, (ii) no maintenance, (iii) restoration (meadows). According results, since 19th Century, increased is responsible for 17-cm level increase, if grows even denser, further 7 cm could be expected. As increases, overbank decreases, crevasses conveyance zones gradually lose their function. Simultaneously, increases in channel (from 1 m/s 1.4 m/s), resulting an incision. Applying LiDAR-based makes it possible plan sustainable maintenance (e.g., forestry, species clearance) from both ecology control perspectives.

Freshwater ecosystems and their bordering wetlands riparian zones are vital for human society biological diversity. Yet, they among the most degraded ecosystems, where sharp declines in biodiversity driven by activities, such as hydropower development, agriculture, forestry, fisheries. Because freshwater characterized strongly reciprocal linkages with surrounding landscapes, activities that encroach on or degrade ultimately lead to freshwater-riparian ecosystem functioning. We synthesized results of a symposium freshwater, riparian, wetland processes interactions analyzed some major problems associated improving research management. Three distinct barriers lack involvement local people conservation management, absence adequate measurement separate legislation policy Based our findings, we argue efforts should be integrated more explicitly. Best practices overcoming 3 improved include sustainable use traditional other forms ecological knowledge, choosing appropriate metrics monitoring restoration efforts, mirroring close links between policy. Integrating these angles science practice will provide substantial benefits addressing crisis.
