“…The background data and findings outlined in this study provide an important baseline assessment against which restoration success in the Waimatā catchment can be measured in the future, recognising that an ongoing commitment to monitoring is required to assess the effectiveness of such initiatives (Guimarães et al, 2021). In the words of a Waimatā resident, ‘We are doing good, but we can do so much better’.…”

“…River restoration and its success are commonly guided by and measured through ecological, biogeochemical, geomorphological and engineering indicators (Eden & Tunstall, 2006). However, restoration extends beyond scientific and technical considerations, as sociocultural, economic and political processes formulate goals and objectives in efforts to meet community and institutional aspirations (de Bell et al, 2020; Guimarães et al, 2021; Johnson et al, 2018; Usher, 2023). Typically, emphasis upon human needs and aesthetic values include concerns for livability, safety and control (Dufour & Pi é gay, 2009; Eden & Tunstall, 2006; Junker & Buchecker, 2008).…”

Surveys of sociocultural relations to rivers provide critical baseline information to appraise the effectiveness of restoration programmes. Findings from a mixed‐methods case study (document analysis, catchment‐wide questionnaire, semi‐structured interviews) show how local relations to the Waimatā River vary in upper, middle and lower catchment areas, in part influenced by historical (family) connections. Personal interactions with the river, and implications for mental and physical well‐being, decline with the perceived condition of the river. While respondents indicate the negative influence of governance arrangements upon river condition, they also highlight positive prospects that blue spaces can shape the co‐design and implementation of restoration activities.

“…Past and present human alterations may have substantially altered geomorphic context. Recognition of the natural or human‐induced constraints that may limit heterogeneity, connectivity, and retention is critical to effective restoration (e.g., Grabowski et al, 2014; Gulmarã et al, 2021; Kondolf, 1998).…”

Process‐based river restoration seeks to restore processes such as channel‐floodplain connectivity that create and maintain river corridor functions. Process‐based restoration can fail to produce the desired results if geomorphic context is not effectively incorporated into restoration design. Geomorphic context of a river reach refers to the controls on contemporary river form and process. Controls at the catchment‐ to reach‐scale include geologic history, biophysical characteristics, legacies of past human alterations, position within the river network, river corridor geometry, base level stability, disturbance regime, and contemporary human alterations of the river corridor. We conceptualize a river corridor as reflecting the interactions among fluxes of material and the geomorphic context. We discuss how an understanding of geomorphic context can be used to select a restoration approach and provide examples of how restoration can fail to achieve desired outcomes when geomorphic context is not considered. Within the toolbox of methods used to implement process‐based restoration, we differentiate the alteration of inputs to the river corridor and fluxes of material through the corridor from alteration of form and/or connectivity within the river corridor. Historical, biotic, geologic/geomorphic, and reference sites can be used to inform process‐based restoration targets. Restoration is strongly influenced by human perceptions of what is appropriate and achievable at a site and diverse communities influencing restoration at a site may differ in their perceptions. Geomorphically based conceptual guidelines, such as the River Styles Framework, provide an effective platform for incorporating an understanding of geomorphic context into process‐based river restoration.

“…However, urban rivers are susceptible to severe habitat degradation and pollution in the past decade [19], and their ecological function on linking the fragmented habitats is neglected. Conservation, restoration and rehabilitation of the urban river can not only benefit to the river ecosystem itself, but also establish the network for biodiversity connections [20]. Reports showed that maintaining and restoring watershed vegetation corridors in urban landscapes can aid efforts to conserve freshwater biodiversity [18].…”

Background Urbanization process around the world has not only changed the patterns of land use, but also fragmented the habitat, resulting in significantly biodiversity loss. Urban rivers, serve as one of the natural corridors in urban ecosystems, are of importance for urban ecosystem stability. However, few studies have been done to explore the relationship between vegetation and pollinators in urban river segments. In this study, two urban streams in the city of Chongqing were selected as the study area, riparian vegetation, butterflies and bees were investigated along all four seasons of a year to illustrate the spatial and temporal distribution patterns. Simultaneously, the ecological functions of the river corridor were analyzed. Result In this study, 109 plant species belonging to 95 genera of 39 families were recorded; the number of sampled species for butterflies and bees were 12 and 13, respectively. The temporal and spatial patterns of species diversity among vegetation, butterfly, and bee are different, but the trends of variation among them are similar between the two streams. Bees were found to be more closely correlated with native flowering plants in riparian zone, rather than with cultivated riparian vegetation. Conclusions The native riparian vegetation in urban rivers plays an important role in urban biodiversity conservation by serving as a corridor. This study provides data supporting the protection of the remaining natural patches and restoration of damaged habitats in the city. The survey has accumulated data on native riparian vegetation and pollinators in urban rivers.
