   Författare :Lina Herbertsson; Miljövetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollinators; pollination; agri-environment schemes; beekeeping; oilseed rape; sown flower strips; agri-environment measures;

   Sammanfattning : Agricultural intensification and associated loss of semi-natural grasslands, has resulted in reduced landscape heterogeneity. A concomitant loss of forage and nest sites for pollinating insects has driven declines across several pollinator taxa. LÄS MER
