  1. 1. Optimal Discharge from a Hydropower Plant for Fish Reproduction: An Aquatic Habitat Model

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Hugo Lindbäck; [2023]
    Nyckelord :Weighted Usable Area WUA ; minimitappning; HEC-RAS; salmo; Helge å; den nationella planen för omprövning av vattenkraft NAP ; Technology and Engineering;

    Sammanfattning : Hydropower is the dominant source of electricity in Sweden, constituting 45% of the national supply. While pivotal for decarbonization and climate goals, its environmental impact on freshwater biodiversity is concerning. LÄS MER

  3. 2. Assessment of hydropower mitigation measures for fish habitat rehabilitation with a coupled eco-hydraulic model : A case study on the Skålan-Äldern stretch

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Francesca Polato; [2021]
    Nyckelord :hydropower; mitigation measures; ecological flow assessment; hydraulic modeling; physical habitat models; vattenkraft; begränsande åtgärder; ekologisk flödesbedömning; hydraulisk modellering; fysiska livsmodeller;

    Sammanfattning : In the past century, hydropower development in Sweden has been facilitated by the lack of appropriate environmental legislation. This exploitation has resulted in the current poor ecological status of most Swedish water bodies affected by hydropower, and in the need for new policies that reflect the 2000 European Water Framework Directive.

  4. 3. Restaurering av grön infrastruktur för fyra naturskogsarter på Söderåsen i Skåne

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Johanna Schroeder; [2018]
    Nyckelord :entita; mindre hackspett; taggbock; bokblombock; GIS; habitatmodell;

    Sammanfattning : Det intensiva brukandet av svenska skogar har inneburit att många arter missgynnats och hälften av landets rödlistade arter är knutna till skogslandskapet. Sverige har förbundit sig att bevara den biologiska mångfalden och ett verktyg i detta arbete är att jobba med grön infrastruktur. LÄS MER

  5. 4. GIS-based modelling to predict potential habitats for black stork (Ciconia nigra) in Sweden

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Malin Sörhammar; [2015]
    Nyckelord :black stork; habitat suitability analysis; reintroduction; geographical information systems;

    Sammanfattning : The black stork (Ciconia nigra L.) was lost from the Swedish fauna in the 1950’s. An increased understanding of the need to save endangered species has led to restoration or preservation of populations through reintroductions. To have background information about a species’ habitat requirements is important for introduction programs. LÄS MER

  7. 5. Planning green infrastructure using habitat modelling : a case study of the common toad in Lomma Municipality

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :William Walker; [2014]
    Nyckelord :adaption to climate change; green infrastructure; planning; ecosystem services; habitat model; common toad; Bufo bufo; Earth and Environmental Sciences;

    Sammanfattning : For an ecosystem to be able to continue to provide important services to society, it must be able to adapt to change. As part of an ecosystem, the ability of a species to migrate in the landscape is vital for the adaption to change. A green infrastructure allows the movement of species in a landscape fragmented by human influenced land use. LÄS MER
