The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation
The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours.
In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.
Skiktning och strukturell utveckling i unga naturlika skogsplanteringar: :
Multilayered woodland types are an important part of the urban forest. The knowledge how to establish and maintain such plantations are not as deep as other knowledge fields concerning forestry. Therefore this study has looked upon how to achieve multilayered structures in young nature-like woodland plantations. As a theoretical base for the study three different major knowledge culture have been studied that concerns the subject, ecology, forestry and landscape management/design. This three theoretical framework concludes that many natural processes strive in the opposite direction of multilayered structures in their youth.
Skogsmarksgödsling : en ekonomisk analys av olika gödslingsstrategier för ett skogsinnehav i norra Sverige
The purpose of this study is to analyze the economic effects of different fertilization programs both on stand- and forest-level. The study is applied on an objective sample of inventory data for a forest area in Kalix in northern Sweden. The forest area belongs to the forest company Sveaskog. The study includes different economic models and will be used as a support when the company decides how to invest and how much to invest in fertilization.
The study investigates the economy of five different fertilization policies. For each program the rate of interest invested in fertilization and the cost for the extra produced volume has been calculated.
Mellanskogs medlemmars syn på röjning
The main purpose of this study is to investigate the needs of pre-commercial thinning on private owned forest properties, which is considered to be increasing. The reason is believed to be the high cost of labor that pre-commercial thinning brings. Furthermore thinning is costly, the revenue created through pre-commercial thinning are post-poned until the first thinning.
The study was made through a survey among members of Mellanskog forest owners association. The survey was distributed by e-mail. The time to answer was set to two weeks.
The answers indicate that the most common reason why the pre-commercial thinning is delayed, or not done at all, is the forest owner?s lack of time.
Marknadsundersökning om vad skogsägare vill ha för produkter/tjänster av skogsbolagen
The goal of this work is to get as good a basis as possible to explain what the owners want for products and services when those doing business with buying groups in Korsnäs purchases regions: Gävleborg, Dalarna, Uppland and Frövi. It should also provide Korsnäs knowledge of the most important factors to consider in business with the owners. Another important aspect is to find out what you have done better at the business with owners, to eventually be able to preserve and take them into account.
300 questionnaires sent out to randomly selected owners in these regions. This is to find out what the owners did not have the products/services of Korsnäs. 29 questions were asked in the affected areas to identify what was missing and to eventually be able to satisfy them.
Vad skapar stress respektive trivsel hos avverkningslag? : en jämförelse mellan bolags- och entreprenörslag
As a student during my studies, I have been told about entrepreneurs who have red numbers in their financial statements, and there is a forest machine operator shortage in Sweden. The basic idea of this thesis was to examine the underlying factors that may have caused the problems described above.
The aim of this thesis was to investigate the factors that create stress and job satisfaction as a forest machine operator. The study was performed as a comparison between forest companies own harvesting teams and entrepreneur teams to investigate if there are any differences in stress and job satisfaction between the two different types of team. The study was conducted in collaboration with SCA Skog.
The material for this study was collected by doing interviews with SCA's harvesting teams. A total of 27 forest machine operators were interviewed, divided into a total of 10 separate harvesting teams.
It was very similar between the different type of teams, which situations the operators experienced stress.
Sagans skog - textil vägg för flexibla rum i offentlig miljö
The story of the forest - A folded textile wall for flexible rooms in public spacesIn the story of the forest the dragonfly is spinning yarn shiny as the sun. In the story of the forest almost everything can happen and almost everything is also happen there.Inspiration from Lennart HellsingThe goal in this exam work was to create a calm, playful space for children in public spaces. A place where children can hide and relax without being disrupted by the surrounding, a place where their imagination can grow and take place. The goal was also to make a flexible space for public spaces that could be used in different ways. Today many libraries want to be more than a library, they will work as a meeting place and you can find several activities to join in.
Jaktens betydelse för Södermanlands landskap : Hur viltvård kan påverka variationen av lövträd och buskar
The fragmentation and reduction of deciduous forests in Sweden is threatening many species. Particularity worrying is the loss of broad-leaf trees, since a diversity of species is often associated to them. Today many deciduous trees are situated along the border between forested and open areas, and these small fragments can be important for biodiversity.The aim of this study is to analyze if wildlife management can affect the variation of deciduous trees and bushes in the landscape. In brochures and literature Svenska Jägareförbundet (the Swedish Association for Hunting and Wildlife Management) recommend hunters and landowners to promote deciduous trees ? often broad-leaf trees ? as wildlife management measures, while the Swedish forestry laws can be sensed as unclear regarding the treatment of these trees.Five properties in Södermanland, Sweden, were chosen as study areas and inventoried in respect of trees and bushes in September 2013.
Motiv och värdering vid köp av skogs- och lantbruksfastigheter i Kronoberg och Blekinge
The purpose of this study is to find out how buyers of forest-and farm land have valued the property's various parts. How buyers has valued the forest, field, pasture, house and the farm buildings on their property. A questionnaire with 22 questions was sent to 68 people how had bought a property in Kronoberg or Blekinge. They had bought the property in 2010 and first half of 2011, and the properties have been provided by LRF-konsult.
To each question there were several alternatives and the buyers would choose the alternative that was most similar to his or her opinion. The study is based on 57 responses.
Hur kopplad är asp till tidigare jordbruksmark? : en studie av aspförekomst och tidigare markanvändning i fem län i Mellansverige
Aspen (Populus tremula) is a tree that is important for biodiversity. It is a pioneer tree that is favored by much light. It is possible that aspens that regenerated on agricultural land have a different importance for biodiversity than aspens that regenerated in forests, since their conditions have been different. By studying how the land use have changed you can see how many of today?s aspens regeneretad on agricultural land.
Rotpostvolym = stämplingslängd?
This work was conducted during spring and summer 2012 together with the company Uppsala Academy of Management as the principal. The two main objectives for the work are that:
? Make a comparison between the measured volume in the standing forest and the measured volume at the industry on Uppsala Academy of Managements actual stumpage sale volume to see how well it conforms.
? Examine if the buyers see any particular advantages or disadvantages of actual stumpage sale volume and what they think of Uppsala Academy of Managements actual stumpage sale volume and structure in general.
I chose to use actual stumpage sale volume from the tree years 2009, 2010 and 2011 in my work. I divided the actual stumpage sale volume following four categories which was pine, spruce, pine/spruce and seed trees. After that I picked out sixteen actual stumpage sale volumes from each category to be a part of the work.
Träddelsuttag eller massavedsuttag i förstagallring?
The purpose of this study is to compare the economic differences between withdraw of forest fuel and withdraw of pulpwood in first thinning, to see which method gives the maximum profitability (income - cost). Another purpose is to investigate the economic impact of the thicket cleaning.
The study compares four different methods: i) pulpwood output with thicket cleaning, ii) pulpwood output without thicket cleaning, iii) forest fuel output with thicket cleaning and iv) forest fuel output without thicket cleaning. The study was conducted in a 30-years old stand, dominated by spruce, outside Harg in Uppland.
The method that generated the best economic net income was pulpwood without thicket cleaning. It generated a positive net of 1,383 SEK per hectare. Forest fuel output without thicket cleaning also generated a positive net in 720 kronor per hectare.
Marknadsundersökning om markägarens val av skogspartner
The driving forces from the forest owners point-of-view was studied on a market where several buyers attend to procure round-wood. It was concluded that forest owners prefer personal contacts to other means of communication, but that it is essential that the initial contact is a personal letter on paper. Furthermore, although price is always important, long standing relations is asked for. The buying companies need skillful experienced buyers that can provide more than just quick closures of deals..
Skattningar i gallringsskog med hjälp av flygburen laserskanning : beräkningar med massaslutenhet
This master?s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The study area was in the municipality of Älvsbyn (Latitude 65° 40´ N, Longitude 21° 00´ E), in northern Sweden.The Swedish authority Lantmäteriet is currently laser scanning most parts of Sweden, providing new opportunities and applications. The primary aim of the national laser scanning is to create a new elevation model, useful in consequence analysis of climate changes.
Traktstorlek före och efter omarrondering i Dalarnas län -frågor kring Lantmäteriets båtnadsberäkning
Land consolidation is a major problem in many countries in Europe. In Sweden, mainly the state of Dalarna, there is a strong consolidation of forestland, probably the strongest in all of Europe. The consolidation is a big obstacle for Forest management and ownership questions due to the often long and narrow strips of land. One of the main reasons for land consolidation in Dalarna results from the heritage procedure, were land is divided between all of the inheritors.
To improve the consolidation large surveys in the consolidated villages in Dalarna are carried out. Many laws have to be followed due to the survey.
