    Abstract : Öppna gräsmarker är viktiga för många olika djur och växtarter, de är dock inte lika vanliga som de en gång var och i samband med ett moderniserat jordbruk. Dessa gräsmarker är ofta beroende av skötsel i form av till exempel slåtter eller bete för att bibehålla sina ekologiska strukturer, som till exempel låg näringshalt och stora öppna ytor. READ MORE

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Stephanie Jonsson; [2021]
    Keywords : Dead wood; arthropod; pest mitigation;

    Abstract : Forests provide humans with a range of valuable ecosystem services, but current forest management practices may increase susceptibility to damage from disturbances such as pest insects. One such practise is the harvesting of residue, which decreases the amount of dead wood in the forest. READ MORE
