Env Semi Natural Conditions Promote Ecological Recovery Of Urban Streams

Sep 28, 2022 This study considers the potential for recovery of invertebrate communities in urban streams based on 12 years of data from a city in Lower Saxony, Germany. The researchers report that streams with natural features and good water quality tended to recover well, given suitable climatic conditions.

Jul 9, 2022 Semi-natural conditions promote ecological recovery of urban streams. Freshwater ecosystems in urban areas face a variety of pressures and are often significantly degraded. This study considers the potential for recovery of invertebrate communities in urban streams based on 12 years of data from a city in Lower Saxony, Germany.

May 1, 2021 Although relict sites of natural and semi-natural ecosystems can be found in urban areas, environmental conditions and species composition of most urban ecosystems are highly modified, inducing the development of novel and hybrid ecosystems.

Jun 25, 2023 Our results underline that community changes following urban stream restoration are closely linked to the evolving environmental conditions of restored streams, in particular habitat availability initialised by riparian vegetation. It takes about a decade for the development of a rich and stable community.

Jan 5, 2021 The goal of this chapter is to identify potentialities and challenges in utilising a social learning approach to facilitate dialogue between a range of stakeholders involved in the restoration of an urban stream in a context of socio-ecological vulnerability.

Sep 1, 2011 The macroinvertebrate communities of both restored and urban degraded streams were correlated with environmental variables characteristic of degraded urban systems. Our study suggests that reach-scale restoration is not successfully mitigating for the factors causing physical and biological degradation.

Jan 7, 2021 In this study, we assumed that river rehabilitation refers to a set of ecological and managing actions aimed to recuperate the natural conditions of a river system to sustain biodiversity, permit recreational uses, manage floods, and conciliate the landscape progress.

Jun 1, 2021 Three recursive humannature coevolutionary scenarios were identified based on key observations: (1) socialecological temporal misfit scenario; (2) socialecological functional fit scenario; and (3) ecosystem service trade-offs scenario.

Oct 1, 2019 Rehabilitation of channel form is a common approach for undertaking urban stream ecosystem restoration. . Potential of alternative channel rehabilitation designs to restore instream hydraulic conditions was investigated. . Rehabilitated urban channels that increases geomorphic complexity can help to restore the hydraulic conditions. .

Sep 16, 2021 We compared ecosystem resilience across four time periods: before the implementation of ecological rehabilitation projects (19902000), during construction and partial implementation of ...

Urban stream renovation uses an iterative process whereby short-term ecological and societal outcomes generate public support for future actions, which may provide opportunities to address catchment-level causes of impairment that often exist across broad temporal scales.

Nov 29, 2022 Moreover, restoration of river ecological corridors can reduce the adverse effects of habitat fragmentation caused by rapid urban development, which is crucial to enhance the linkage of ecological patches, and recover the ecosystem function and service .

Jan 25, 2015 Stream restoration seeks to re-establish ecological structure and function of river systems, and understanding its ecological consequences is a current focus of stream ecology.

Nov 26, 2020 The tool called Urban stream Assessment system (UsAs) includes the assessment of (1) biodiversity, (2) ecological functions and habitat that are inherent components of the ecosystems, and (3 ...

The urban stream syndrome is of great concern because ecosystem functions and services can be profoundly diminished where in-stream conditions diverge from the range of conditions typical of natural streams.

Urban streams provide valuable ecosystem services including heat reduction, flood control, and recreational areas (Meyer et al. 2005). In lower-income countries, urban streams also are used for small-scale or recreational fishing, sources of building materials (e.g., sand, gravel), and water for irrigation and household uses (Corcoran et al ...

Feb 12, 2024 Our results show that despite some differences (e.g. top-down versus bottom-up and functional versus taxonomic approaches) and notably with distinct goals recovery of a defined historically determined target ecosystem versus recovery of natural processes with often no target endpoint ecological restoration and rewilding have a common ...

Jun 21, 2018 Expanding the area of high quality semi-natural habitat to cover 40% of these landscapes (an increase of 33%) to enable these large areas to be foci for the development of resilient ecological networks. (=Better & Bigger) (iii) Increase the area of habitats under long-term protection for nature. The Convention on Biological Diversity (CBD) has ...

Jan 6, 2016 Abstract The field of urban stream ecology has evolved rapidly in the last 3 decades, and it now includes natural scientists from numerous disciplines working with social scientists, landscape planners and designers, and land and water managers to address complex, socioecological problems that have manifested in urban landscapes. Over the last decade, stream ecologists have met 3 times at the ...

PMID: 34838565. DOI: 10.1016/j.scitotenv.2021.151974. Abstract. Urban expansion and the transformation of rural areas into suburban areas along with increasing human pressure can cause major changes in the environment. Typical effects of urbanization include degradation of aquatic ecosystems.

Jan 1, 2015 Ecological thresholds and resilience are powerful heuristics for understanding how lotic ecosystems change. Ecosystems may exist in self-organized states based on their taxonomic composition or the range of ecosystem functions, which are influenced by environmental drivers such as thermal or hydrologic regimes, channel morphology, and ...
