    Abstract : Parkslide (Reynoutria japonica) har sitt ursprung i östra Asien, i bland annat Kina och Japan. Den introducerades till Europa som prydnadsväxt på 1800-talet och har sedan dess spridit sig från parker och trädgårdar ut i natur- och kulturlandskap. READ MORE

  3. 22. Limestone Quarry Restoration - Evaluation plan of restoration methods for Alvar establishment on northern Gotland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ola Ohlsson; [2020]
    Keywords : Limestone quarry; alvar; restoration; evaluation plan; ANOVA; environmental monitoring; Science General;

    Abstract : Alvars are globally rare habitats with rich and distinctive vegetation-communities. Alvars are found on limestone bedrock which is also subject to quarrying for cement production. The increasing global need for cement results in either expanding existing quarries or the opening of new ones. READ MORE

  4. 23. Att skydda det skyddade : korttidseffekter av hägn på trädföryngring i tre skånska skogsreservat

    Abstract : Biotiska och abiotiska faktorer har stor inverkan på vilka arter som växer i skogen. Graden av inverkan kan bero på betesskador från klövvilt och tillgång på ljus. Betesskador och ljustillgång kan dels reglera nivån på föryngringen, dels på fördelningen av trädslag i den tempererade skogen. READ MORE
