Semi Natural Conditions Promote Ecological Recovery Of Urban Streams





Semi-natural conditions promote ecological recovery of urban streams

28/09/2022 They advise that authorities could enhance the ecological quality of urban streams by reducing organic pollution and stream degradation. They recommend avoidance of high-intervention management regimes such as total removal of aquatic plants and streambed stabilisation; and instead, to allow/promote the development of more natural stream structures through low-intensity maintenance.

Semi-natural conditions promote ecological recovery of urban streams

28/09/2022 Semi-natural conditions promote ecological recovery of urban streams Biodiversity 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.

ENV - Semi-natural conditions promote ecological recovery of urban streams

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.

Ecological resistance in urban streams: the role of natural and - USGS

However, the heterogeneity also may arise from variation in hydrologic, biological, and physicochemical templates that shaped stream ecosystems before urban development. We present a framework to develop hypotheses that predict how natural watershed and channel attributes in the pre-urban-development state may confer ecological resistance to urbanization.

Ecological resistance in urban streams: the role of natural and legacy

Abstract. Urbanization substantially changes the physicochemical and biological characteristics of streams. The trajectory of negative effect is broadly similar around the world, but the nature and magnitude of ecological responses to urban growth differ among locations. Some heterogeneity in response arises from differences in the level of urban ...

The importance of natural versus human factors for ecological - USGS

12/11/2019 Covariation between natural and human factors accounted for a higher proportion of explained variance of in-stream environment than unique effects of human factors in most ecoregions. Ecoregions with relatively weak effects by human factors had relatively high levels of covariance, high levels of human disturbance, or small ranges in human disturbance.

Urban environment

16/11/2022 Reusing materials from existing buildings (or urban mining) has been proposed as a means to reduce demolition waste, raw material consumption and greenhouse gas emissions. This study models the opportunities for urban mining in the Netherlands under practical constraints, up to the year 2050.

The importance of natural versus human factors for ecological - PubMed

20/02/2020 PMID: 31810677. DOI: 10.1016/j.scitotenv.2019.135268. Streams are influenced by watershed-scale factors, such as climate, geology, topography, hydrology, and soils, which mostly vary naturally among sites, as well as human factors, agriculture and urban development. Thus, natural factors could complicate assessment of human disturbance.

Global perspectives on the urban stream syndrome

18/12/2015 Urban streams are prevalent throughout the world, and the altered ecosystem structure and the reduction in services provided by these systems has led to an exponential increase in research on urban streams in recent years (Wenger et al. 2009, Smucker and Detenbeck 2014) and to multiple descriptions of the suite of typical physical and ecological responses to urbanization, collectively termed the urban stream syndrome (Meyer et al. 2005, Walsh et al. 2005). The urban stream syndrome provides ...

Temporal changes of biodiversity in urban running waters Results of a

01/02/2022 Intensive maintenance with regular removal of vegetation can negatively impact macroinvertebrate abundances and assemblages (Monahan & Caffrey, 1996), thus less intensive maintenance may promote recovery by reduced disturbance and by development of more natural stream conditions (WVT (Wasserverbandstag e.V. Bremen, Niedersachen, Sachsen-Anhalt), 2020). Interestingly, as two-sided bankside mowing was reduced to alternate bankside mowing in 2012, the increase in taxon richness in the second ...

Recovery and resilience of urban stream metabolism following Superstorm

06/04/2017 However, the recovery intervals exhibited by these urban streams were similar to those found in naturally flashy desert streams (Fisher et al. 1982, Grimm 1987), suggesting that urban streams can adapt to floods and other disturbances in spite of myriad environmental stressors (Grimm et al. 2017). Overall, we found that urban streams can exhibit high metabolic activity despite a multitude of physicochemical stressors and that this metabolism rapidly recovers from floods, regardless of magnitude.

We tested the applicability of a rapid visual socialecological stream assessment method for restoration planning, complemented by a citizen survey on perceptions and uses of blue and green infrastructure.
