Renar och klövvilt på järnvägar : en studie i järnvägars effekter på ren, älg och rådjur i norra och mellersta Sverige under 2005

Roads and railroads have significant impact on the surrounding landscape and the wildlife living in it. This study aims to provide an overview of the effects caused by railways to reindeer, roe deer and Moose in Sweden in order to make more detailed assessments within this topic in the future. The method used is a study of literature on the subject and a synthesis of databases with information about wildlife mortalities, traffic intensity and fences in the study area; northern and central Sweden. The databases were used to compile digital maps using ArcGIS. Infrastructure brings change to the surrounding landscape and its function as habitat for wildlife. Railroads cause barrier effects such as fragmentation, wildlife mortality, loss of habitat and loss of connectivity.

Effects of brown bear (Ursus arctos) odour on the patch choice and behaviour of different ungulate species

The return of large predators to regions where they were previously extirpated has created a need for knowledge about their effect on prey species, not only their lethal but also their behavioural or risk effects. In this study the behavioural risk effects of brown bear (Ursus arctos) were tested on fallow deer (Dama dama), roe deer (Capreolus capreolus), red deer (Cervus elaphus), Moose (Alces alces) and wild boar (Sus scrofa). This was done by using patches of fur to simulate the presence of the novel predator (brown bear), a novel nonpredator (reindeer (Rangifer tarandus) and no fur as control. These three treatments were then compared. The response variables measured were increased vigilance, decreased feeding time and change in patch use.

Viltets inverkan på vegetationsutvecklingen i en Sydsvensk skogsföryngring :

Herbivore impact on the Swedish forest has under a long time been a common subject of debate. There are many different opinions depending on what direction the forest owner has with his/her forest. Populations of Moose and roe deer have increased significantly in Sweden during the last decades. The purpose of this study is to get a full picture of the herbivore impact on the regeneration areas. The field work was done once a year for seven years (1999?2005).

Betesskador på lärkplantor

The purpose of this study was to show how the Hybrid Larch (Larix eurolepis x) are used by large herbivores in terms of grazing and fraying. More specifically I studied how impact on the seedlings was affected by forest stand area, tree height and stem density (stems/ha).The survey was done in Jönköpings county in southern Sweden. About 50 % of all stems that are measured are damaged by grazing and 5,8 % was damaged from fraying. The conclusion of the study is that the biggest influencing factor is the height of the seedlings. The size of the stands and number off seedlings per hectare have almost no impact on the injuries on the seedlings. Fraying are common on trees smaller than 3 meters, and doesn?t occur on trees above that height.

Förändringen av tall- och granbestånden i eklandskapet söder om Linköping, 1927 jämfört med 2013

The aim of the study was to compare how the population of pine (Pinus sylvestris) and spruce (Picea abies) have changed between 1927 and 2013 in the oak landscape south of Linköping. A field study was carried out in 22 two kilometre lines which also had been studied in 1927. In these lines, which where ten meters broad and had a direction from west to east, the pines and spruces were counted, measured and classified by steam diameter. The obtained result was that the basal steam area (m²/ha) had increased for pine (44%) and spruce (57%) between 1927 and 2013. The amount of trees had increased in all diameter classes except thinner pine and spruce with a diameter of 5-10cm.

Metoder för att beskriva kumulativa effekter med avseende på biologisk mångfald och vägar :

Cumulative effects are seldom treated in Swedish Environmental Impact Assessments (EIA). This report treats these questions and which procedures and methods that can be used when assessing cumulative effects in EIA. This report is a literature study where also a case study is a part. The case study shows how existing methods for cumulative effects can be used in practice. The report is concentrated on biology and treats cumulative effects on premises of biodiversity and roads. Cumulative effects include both direct and indirect effects.

Rovdjurens påverkan på den svenska älgstammen och konsekvenser för dess förvaltning

Den svenska älgstammen har i stort sett levt i frånvaro av björn och varg under större delen av 1900-talet. Istället har stammen reglerats genom en intensiv älgjakt. Nu har både björn och varg återetablerats i våra skogar och expanderar i antal och utbredning. Syftet med denna studie är att ta reda på hur återkomsten av dessa stora rovdjur påverkar älgstammens antal, köns- och åldersstruktur och beteende, samt hur älgförvaltningen påverkas av närvaro av björn och varg. Rovdjursstammarna är ojämnt fördelade över landet och även älgtätheten varierar. Därför kommer en del områden att påverkas mycket och andra väldigt lite.

Mångbruksplan inriktning vilt och viltvårdsanpassning av skogen

This multiple use forestry plan is made on the property Basunda which is located in the southern parts of the province Östergötland. The owners of the property today are Jonas and Ulrik Saanum, but it has been in the family since their grandfather bought it 1933. There is a slaughterhouse on the property in which they take care of domestic cattle and animals from the forest. Jonas and Ulrik are also dedicated hunters. These are the two reasons to why the focus is wildlife and wildlife management. The question at issue of this work is simplified: what demands does the wildlife have; and how will the owners be able to fulfill these, what changes in the forest management must be made and will these changes result in a different budget, compared to the ordinary forest management. This work is based from a freshly made forestry management plan. I based my fieldwork on this plan, but made my own management proposals, that would benefit the game.

Mjölkraskorsningar i avelsvärdering av tillväxt hos svenska köttrastjurar

The concerning issue of declining number of hunters in North America is also apparent in Europe and Sweden. When the bulk of research found on human dimensions and hunting participation has almost exclusively been done in the United States, this report seeks to add to the needed knowledge on a national level focusing on the causes of hunter declines related to social factors within Sweden. Using hunter data reaching from commune, county to National level, this report describes the correlation between a number of variables and the hunting participation in Sweden.The typical Swedish hunter lives in an area with low population density, the person usually has higher education, the living situation is stable with no recent moving and there is relatively good access to forest land. Persons with weaker connection to the Swedish culture such as foreign citizens, people with foreign background and people born outside ?the Nordic countries? are less likely to start hunt or participate in hunting.A strong relationship was found between the favorite game, Moose (Alces alces), and the amount of hunters participating in the hunting.

Klövviltets nyttjande av foderraps på viltåker och betespåverkan på angränsande skog

Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.

Analys av hemområdesstorlek hos mellansvenska vildsvin (Sus scrofa scrofa)

The wild boar population grows rapidly in number in Sweden, and it has been predicted that the annual number of shot wild boar will soon exceed the cull of Moose. According to estimates, the Swedish population encompassed some 150 000 individuals in 2010. The mean annual harvest has increased by 30% since 1990, indicating that the wild boar is a species we must learn to manage sustainably. A successful management of the boars aims for a population in balance with agriculture and traffic, and also provides good hunting opportunities. For this to be possible, understandings of several aspects of the ecology of wild boar is needed. The sows in this study had an average homerange of 707 hectares during summer, and 659 hectares in winter.

Fullskale-simulerng av bil-älgkollision med älgkadaver

Dagens äldreomsorg kantas av kvalitetsproblem och arbetsmiljöproblem vilket titt som tätt uppdagas i olika mediala skandaler. Sedan en tid tillbaka har äldreomsorgen i Stockholm konkurrensutsatts och idag bedrivs lite mindre än hälften av stadens vård- och omsorgsboenden av privata utförare. Samtidigt anklagas vinstdrivna bolag för att ta ut höga avkastningar istället för att satsa på kvalitén. I denna studie undersöks hur Stockholms stad följer upp och säkerställer att privata utförare tillhandahåller en god äldreomsorg. Studien visar på att kvalitén i dessa verksamheter är komplex att följa upp och kräver en relation präglad av tillit och förtroende mellan kommun och utförare, och uppföljningen har visat sig likna biktens funktion inom den katolska kyrkan.

Reproduktion hos älg (Alces alces) i Blekinge och nordöstra Skåne 2012-2014 : en studie av honliga reproduktionsorgan, älgobservationer och klimatdata

Älgen är idag en art av stort intresse för det svenska samhället. Främst som resurs, men arten arten kan också orsaka problem i form av trafikolyckor och betesskador. Vid förvaltningsbeslut finns det flera olika faktorer att ta hänsyn till och för att bedöma stammens storlek finns ett antal olika inventeringsmetoder. Kunskap om reproduktionen är bland annat viktigt för att uppskatta stammens tillväxt. En metod vid datainsamling är att undersöka honliga könsorgan insamlade under jakt.

Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) in coastal areas of northern Sweden

Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) was studied on 12 sites in coastal areas of northern Sweden. On each site, sample plots were placed in adjacent Norway spruce and Scots pine stands with similar ages in between. Basal area, tree height, Site Index, volume production, simulated maximum mean annual increment (MAImax) and tree vitality were compared for the two species. Average basal area at the time of measurement was 30.4% larger for Scots pine stands than for Norway spruce stands. The difference between the two species in basal area increment during the last 10 years was related to stand age.

Influence of prescribed burning and/or mechanical site preparation on stand stem density and growth of Scots pine stands above the Arctic Circle : results 9-19 years after stand establishment

Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils. The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.
