Summary: Native riparian forests play a crucial role in supporting the ecosystem function for many species, but their regeneration is being hindered by human activities and climate change. To address this issue, a spatially-distributed riparian forest recruitment model was developed to identify the limiting factors and guide management and restoration efforts. The model showed that disturbance mechanism and hydrologic conditions influenced the success of native forest recruitment.

Summary: A restoration project on an alluvial wet-meadow system found that sizing the channel to the effective discharge (Q(e)) can lead to rapid dynamic equilibrium, while excessively wide channels may take nearly 300 years to reach equilibrium.

Summary: Livestock grazing in riparian areas has both positive and negative effects on vegetation. While reserving riparian areas can benefit native vegetation, livestock grazing can reduce exotic vegetation cover at the cost of native vegetation and ground condition. Quantitative monitoring and evaluation of cost-benefit trade-offs are essential for guiding reservation decisions.

Summary: Increasing iron concentrations in freshwaters across northern Europe have led to browning, affecting aquatic organisms and drinking water production. The contribution of different sources to stream iron concentrations is not well understood. This study investigated the role of riparian and mire soils in regulating iron patterns in a boreal stream network over 18 years. Results showed that riparian soils were major contributors to increasing freshwater iron concentrations, and drought events led to prolonged release of iron from organic soils, with potential long-term effects on stream iron concentrations.

Summary: This study used camera trap videos to document wildlife biodiversity and animal activities at several large wood complexes in Rock Creek, Oregon. The results showed that large wood plays an important role in supporting wildlife biodiversity and providing habitat connectivity between terrestrial and aquatic environments. The study also highlighted the variability in the effects of large wood across different stream locations.

Summary: The study compared the use of UAVs, ground surveys, and satellite imagery for evaluating riparian vegetation, showing that UAVs offer efficient and accurate assessments but have limitations in assessing multi-layered vegetation. A combined approach of UAVs and ground surveys is recommended for more comprehensive evaluations.

Summary: The accurate detection and mapping of instream wood is important for sustainable forest management. This study developed and tested a novel framework to use Airborne Laser Scanning (ALS) data to automatically detect and map instream wood. The results showed that the method had moderate overall accuracy and could be used for fish habitat modeling and assessing management practices.

Summary: This study assessed the loads of large wood (LW) in an urban stream and found that the recently reforested area had greater LW volume compared to the forested site and the site with low riparian vegetation density. The study also showed a positive relationship between riparian vegetation frequency and in-channel LW frequency. The findings suggest that a fully forested watershed is not necessary to provide the benefits of wood to urban streams.

Summary: Assessment of riparian vegetation ecology revealed significant variation between two rivers, with higher diversity observed in lower vegetation layers in Machhli river and in tree and herb layers in Maini river. The study highlights the importance of species-oriented plantation practices for successful restoration and conservation of riparian vegetation ecosystems.

Summary: This study analysed the factors influencing the storage of large wood (LW) by living woody vegetation in active channels. It found that as catchment area and channel width increased, and bed slope decreased, the volumes of LW pinned by vegetation decreased. However, the volumetric proportion of LW pinned by vegetation did not increase solely as a simple function of the increasing LW mobilisation rate or the increasing density of woody vegetation in the fluvial corridor. Stable vegetated patches in the channel were also found to play a crucial role in pinning LW.

Summary: The need for hydrologic restoration in stream ecosystems is essential, but funding often falls short. Stormwater mitigation interventions can provide stream mitigation credits by directly improving flow class or indirectly enhancing habitat quality. These interventions can have a positive impact on stream networks and stakeholders compared to conventional habitat restoration alone.

Summary: The study revealed that forested riparian buffers are associated with greater shading, increased gravel content in stream substrates, and faster flow velocities. It also found that riparian vegetation types influence the structural and functional composition of stream invertebrate communities, with implications for stream health and cross-ecosystem connectivity.

Summary: Woody riparian vegetation plays a vital role in supporting aquatic macroinvertebrate communities by providing various beneficial functions. However, these functions are limited by large-scale landuse stressors, although localized riparian vegetation can still have some effects. These findings are important for guiding restoration measures targeting macroinvertebrate communities.

Summary: Climate change and riparian management are significant drivers of hydrological change, impacting nutrient fluxes in lowland streams. Long-term assessment in a mixed land use catchment in northern Germany revealed how climatic variability influences hydrological dynamics, with discharge and groundwater levels closely linked to changes in temperature and rainfall. The study also highlighted the role of beaver dams in moderating flow regimes and facilitating groundwater recharge, as well as the complex dynamics of nutrient concentrations and fluxes in stream water systems.

Summary: This study highlights the impact of uncertainties, including ontological and framing uncertainties, on policy reform decisions. Despite efforts to objectively identify the most parsimonious classification, the final decision-making process was influenced by subjective factors and trade-offs among credibility, relevance, and legitimacy. The study suggests that reducing ambiguities and framing decision problems in terms of risks to management objectives could improve the decision-making process in policy reform.

Summary: Cultural monitoring has emerged in New Zealand as a mechanism to revitalize indigenous knowledge and support treaty-based governance. However, there is a need to be cautious about how institutionalization of cultural monitoring may modify or constrain its intent. By examining three examples of cultural monitoring, this study analyzes how different institutional mechanisms enable or hinder the decolonizing intent of cultural monitoring.

Summary: In Aotearoa New Zealand, catchment communities have actively worked on restoring river health, offering valuable knowledge to empower other groups and make restoration efforts more effective on a large scale. Through interviews with five catchment groups, we found that storytelling as a tool could inspire freshwater restoration action in their own community and beyond. Each group created a Catchment Journey, using graphical artwork to narrate their land, people, and restoration activities. Key elements for effective knowledge sharing in collective catchment storytelling include the role of respected storytellers, recognition of responsibility to act, and authenticity.

Summary: Metaphors are extensively used in environmental science and policy to simplify complex ideas and promote ethical engagement with the natural world. This study examines the institutionalization of metaphors in freshwater politics and governance in Aotearoa New Zealand, highlighting their origins, strategic purposes, and limitations. Scientists play a significant role in shaping metaphorical meanings and influencing both regulatory institutions and informal norms related to metaphor implementation.
