    Abstract : The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. READ MORE

  3. 22. Effect of planting density and abiotic conditions on yield of Betula pendula and Pinus sylvestris seedlings in monoculture and mixture

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Jennifer McGuinness; [2014]
    Keywords : abiotic environment; Betula pendula; density gradient; Interaction effects; Pinus sylvestris; Planting density; planting composition; seedling yield;

    Abstract : How the yield of mature stands changes in response to factors such as stand composition, planting density and abiotic conditions is a developing topic, and underpins models and generalizations used by forest managers today. However, these generalizations are both the subject of debate and are limited to mature stands, leaving a knowledge gap concerning both mixed species stands and younger stands. READ MORE

    Abstract : Skogsforskningen i Sverige har alltid strävat efter att öka värdet på skogsmarken, vilket har skett genom växtförädling, markavvattning, gödsling men även genom att introducera utländska trädslag. Pågående klimatförändringar med ökad stormintensitet tillsammans med en ökad koncentration av renodlade granskogar i södra Sverige har bidragit till att blickar har riktats mot alternativa trädslag i skogslandskapet.
