  1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Rasmus Staaf; [2024]
    Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  2. 2. Dynamic minimum flows in the bypass reach of Juktån : A post-implementation evaluation of the effects on riparian vegetation

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Walter Gezelius Gezelius; [2024]
    Nyckelord :Restoration; Environmental flows; riparian vegetation;

    Sammanfattning : The purpose of the paper was to evaluate the effects of the restoration efforts in Juktån on the plant species richness and composition, vegetation zonation and soil composition. The restoration involved implementation of a dynamic flow, in addition to hydro-geomorphological alterations. LÄS MER

  3. 3. Sensitivity of Norway Spruce (Picea abies) to inundation.

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Whitney Cleopatra Vlahakis; [2023]
    Nyckelord :Inundation; riparian zone; spruce seedlings; restoration; mortality;

    Sammanfattning : Alteration of river flow regimes due to dams result in modifications of riparian ecosystem, with impacts on vegetation, landforms, and habitats. A key characteristic that differentiates riparian zones from adjacent aquatic and terrestrial environments is the event of periodic flooding and water logging. LÄS MER

  4. 4. Major forest companies and owner associations interpretation of policies and certification programs regarding riparian buffer zones

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Eric Lundström; [2023]
    Nyckelord :Buffer zone; Water quality; Buffer zone policy; Forestry; Policy interpretation;

    Sammanfattning : Human intervention in forests such as clearcut forestry have a negative impact on water quality and biodiversity. To maintain water quality and its biological values a commonly used method is to leave trees and shrubs closest to the water, in so called a buffer zone. LÄS MER

  5. 5. Biflödens effekt på mångfald och abundans av växter i strandzonen utmed älvar : Test av hydrochorins effekt och den longitudinella teorin

    Kandidat-uppsats, Karlstads universitet

    Författare :Daniel Berger; [2023]
    Nyckelord :biology; ecology; hydrochory; plants; biological diversity; riparian; riparian zone; river collector hypothesis; ume river; vindel river; biologi; ekologi; hydrochori; växter; biologisk mångfald; strandzon; kantzon; river collector hypothesis; umeälven; vindelälven;

    Sammanfattning : The riparian zone is a changeable and species-rich habitat with important ecological functions that have long been affected by human activities such as hydropower and forestry. Rivers and their adjacent riparian zones also constitute a transport route for plant parts and seeds in a form of passive transport, called hydrochory, which can contribute to the establishment of plants or the preservation of diversity in the riparian zone.
