    University essay from SLU/Dept. of Urban and Rural Development

    Author : Hannes Skarin; [2018]
    Keywords : konflikt; naturmark; naturum; tillgänglighet; visuellt upplevelsevärde;

    Abstract : Naturmarker och dess upplevelsevärden förvanskas många gånger av de tillgänglighetsanpassningar som görs i dessa områden. Det finns en konflikt mellan tillgänglighetsanpassningar i naturmiljöer och dess upplevelsevärden. READ MORE

  3. 2. The role of adjacent vegetation on the recovery of riparian flora : Effect of upstream and upland vascular vegetation after stream restoration in a boreal catchment

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Lena Kretz; [2015]
    Keywords : Channelization; demonstration restoration; species composition; species richness;

    Abstract : Restoration of streams that were formerly channelized for timber-floating has become increasingly common. Generally, this restoration returns boulders from riparian zones to streams, leading to wider, more heterogeneous channels with slower flows. READ MORE

  4. 3. Stream channelization effects on fish abundance and species composition

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Ulf Johansson; [2013]
    Keywords : Channelization; Rheophilic species; nemoboreal streams; Nordic multi-mesh Stream Survey Net; lotic; relative abundance; fish community; limnophilic;

    Abstract : Streams are important habitats, providing shelter and feeding opportunities for a wide range of organisms. The species depending on running waters includes a wide array of fish species, using these waters for their whole or parts of their lifecycle. Streams are also the subject of different anthropogenic impact, e.g. READ MORE

  6. 5. Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Viktor Tylstedt; [2013]
    Keywords : Salmo trutta; stream restoration; longevity; erosion; spawning bed; Vindelälven;

    Abstract : Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. READ MORE
