- Rowan and hackberry for wood production in boreal forests, added 22 of May 2012
Rowan (Sorbus aucuparia) occurs throughout temperate and boreal regions of Europe and Asia. It is a significant component in the landscape, but is generally considered an inferior tree species in forestry. Nevertheless, its timber fetches high market prices for furniture, tools and other special uses, the berries are used in food and beverage production, and the tree substantially helps enhance forest biodiversity and forest aesthetics.

- Sycamore in mixed broadleaved forest in southern Sweden, added 26 of April 2012
Sycamore (Acer pseudoplatanus) is a natural component of the temperate mixed broadleaved forest although regarded as an exotic tree species in Sweden. In southern Sweden, we have approximately 50-100 planted Sycamore stands. Most of these are 30-60 years old and mixed with other broadleaves, in particular beech. This master thesis will study the occurrence and survival of natural regenerated Sycamore in surrounding stands and the future potential of Sycamore in mixtures. Results from this study will enable us to evaluating the effect of Sycamore in native broadleaved stands with different objectives; forest production and nature conservation. Is the Sycamore an obstacle or a possibility?

- Vessel size variation in young pedunculate oak, added 12 of April 2012
Subjects: silviculture, tree physiology, wood anatomy
The objective of this thesis is to investigate the early wood vessel size variation of young pedunculate oak (Quercus robur) at different heights along the stem, and the relationship with
time of flushing, ring width and silvicultural management.

- Total volume, stem volume and stem taper functions for sycamore (Acer pseudoplatanus)
Accurate volume and taper functions have been developed for several major tree species. Sycamore is a minor species in terms of area coverage, but it is a highly significant component of temperate forests in Europe and a significant contributor in the forest economy. The few functions available for sycamore are generally of poor quality and often inconsistent in their construction or formulation.

- Pattern of modern fire activity in Sweden: role of human factors
Despite efficient fire suppression, forest fires do occur in Sweden and it is of theoretical and practical interest to understand human and environmental controls of this fire activity. The fires caused by humans are often unintentional and small but in combination with climatic factors like low amount of summer precipitation, may quickly increase in size and pose a serious danger to growing stock and infrastructure. It has been proved in several studies that the natural fires usually occur over a large area and pretty seldom than human induced fires. Understanding the correlations between human presence in the landscape and long-term forest fire patterns helps optimize resource allocation for fire fighting activities. In this project we will use country-wide datasets on different properties of Swedish counties (economical, logistic-, and infrastructure-oriented), GIS, and modern fire statistics to understand non-climatic controls of fire activity in Sweden over the recent decades.

- Role of Gremmeniella epidemics in affecting biomass production of main coniferous species in Central Sweden
Fungal pathogens causing diseases of trees may significantly reduce tree productivity and increase mortality with negative ecological, economic, and social impacts. The fungus Gremmeniella abietina is one of the most serious pathogens on pine in the Northern Hemisphere. In Sweden, it attacks all three major conifer tree species (Norway spruce, Picea abies, Lodgepole pine, Pinus contorta and Scots pine, Pinus sylvestris). G. abietina causes dieback of shoots and buds and forms cankers on stems and branches. In this project we need to assess the damage caused by Gremmeniella through dendrochronological methods. The project involves sampling and analysis of tree-ring data to model the effects of Gremmeniella epidemics on regional scale in mid-Sweden.
This project is cooperation between DELA and Institutionen för skoglig mykologi och växtpatologi at SLU. More info on DELA.

- Development and dendroclimatic analysis of a regional beech chronology of Southern Sweden
The project will endavoir to extract climatic signals from a number of beech site chronologies and to develop a regional beech chronology. Further, the study will attemp to partition climatic, forest management, and masting effects on beech growth, and make sound predictions about dynamics of beech biomass accumulation under future climates.
