  1. 11. The effect of ecological forest restoration on bumblebees (Bombus spp.) in the boreal forest

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Raisja Spijker; [2018]
    Keywords : bumblebee; Bombus spp.; forest restoration; abundance; species richness; species composition; boreal forest;

    Abstract : Insect pollinators are an important part of biodiversity, yet the number of pollinating insects is declining all over the world. Of all the wild plant species about 80% are reliant on insect pollinators, with bees being most important. One of the main causes behind the decline of insect pollinators is the loss and fragmentation of habitats. READ MORE

  3. 12. Reforestation in the far north : comparing effects of the native tree species Betula pubescens and the non-native Pinus contorta in Iceland

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Elin Fries; [2017]
    Keywords : Iceland; non-native tree species; understory vegetation; P. contorta; B. pubescens;

    Abstract : The use of non-native tree species in forestry is both praised and questioned. Foresters have often promoted their use, mainly because of higher growth rates, resilience to pests and diseases and improved survival under harsh conditions. READ MORE

  4. 13. Overstory dynamics as an indicator of ecosystem services from the understory vegetation in coniferous forests in Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Daniel Boczniewicz; [2017]
    Keywords : berry production; biodiversity; ecosystem services; game potential; overstory vegetation dynamics; Picea abies; Pinus sylvestris; understory vegetation; Vaccinium myrtillus; Vaccinium vitis-idaea;

    Abstract : Understory vegetation is a wide and diverse part of the forest environment, which provides a lot of information about the forest, its condition and ecosystem services. Understory vegetation is affected and moulded by the species composition and density of the overstory, which changes growth conditions and productivity in the lower layers during the whole rotation period.

  5. 14. Effects of climate warming on the performance of three boreal tree seedling species in interaction with moss cover and fire history

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Maria-Theresa Jessen; [2017]
    Keywords : ;

    Abstract : Forest regeneration in the form of successful seedling establishment is a key factor for the persistence of a healthy forest ecosystem. Tree seedlings grow in a complex environment shaped by over- and understory and competition for light, nutrients and water. READ MORE

  6. 15. Biophysical changes following landscape restoration : in Changting model restoration site in Fujian province, southern China

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Martin Ewertson; [2016]
    Keywords : afforestation; biomass carbon pools; carbon and nitrogen in soil; broadleaves enrichment; eroded red soil;

    Abstract : China has promised to tackle climate change by decreasing its emission and promote carbon sinks primarily by forest plantations and restorations. There is a growing debate about the impacts of large-scale restorations using few fast-growing species on the kind of ecosystem we are creating and its adaptation to the future environmental conditions.
