  1. 1. Birds and butterflies at the forest-farmland interface

    Författare :Dafne Ram; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conservation; Monitoring; Forestry; Grassland butterflies; Farmland birds;

    Sammanfattning : Land-use change is one of the greatest threats to biodiversity. Through intensification of land-use, the agricultural landscape has become more homogenous and a result, many species associated with traditional farmland or other semi-natural open habitats have declined. LÄS MER

  3. 2. Plant community assembly during succession from arable fields to semi-natural grassland

    Författare :Barbara Christine Schmid; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diversity; arable-to-grassland succession; space-for-time approach; land-use history; plant community assembly; grazing management; connectivity measures; dispersal vector; vascular plants; grassland specialist conservation;

    Sammanfattning : Large areas of grazed, species rich semi-natural grassland were lost in Europe during the last two centuries and as a consequence led to decreases in grassland specialist species. Therefore, today the “restoration” of grassland on previously arable fields is recommended for the protection of grassland specialists. LÄS MER

  4. 3. PV water pumping systems for grassland and farmland conservation

    Författare :Pietro Elia Campana; Jinyue Yan; Bengt Perers; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Grassland degradation is considered as one of the worst environmental and economic problems in China because of the negative impacts on water and food security. The application of the photovoltaic water pumping (PVWP) technology for irrigation is an innovative and sustainable solution to curb the progress of grassland desertification and to promote the conservation of farmland in remote areas.

  5. 4. Disturbance regimes in dry sandy grasslands – past, present and future

    Författare :Anja Ödman; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Grassland conservation; sand steppe; land use history; conceptual model; soil disturbance; lime; nutrient availability; vascular plants; bryophytes; ground beetles; propagule supply;

    Sammanfattning : A number of sandy grassland habitats of interest for biodiversity conservation can be found in Europe. One such habitat is the threatened xeric sand calcareous grassland, which is home to a large number of endangered species. LÄS MER

  7. 5. Conservation of semi-natural grasslands : Effects of different management methods on biodiversity

    Författare :Malin Tälle; Lars Westerberg; Per Milberg; Uno Wennergren; Hans Henrik Bruun; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Species-rich semi-natural grassland are valuable habitats in the agricultural landscape as they may contain a high diversity of both plant and animal species, as well as provide essential ecosystem services like pollination. To keep these habitats open and to maintain the biodiversity in them, management like grazing or mowing is necessary. LÄS MER
