Evaluation of an ectomycorrhizal macrofungi as an indicator species of high conservation value pine-heath forests in northern Sweden
Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.
Effekter av kalavverkning på mindre boreala sjöars vattenkvalitet
Forestry is an important industry in Sweden, with clear-cut as the most commonly used method for harvesting. Here the long-term impact of clear-cut on lake water quality (dissolved organic carbon (DOC), nitrogen, phosphorus and pH) has been investigated, based on 23 lakes sampled during autumn. Data for additional 15 lakes sampled for the Swedish monitoring program were also used. Lakes were classified as 5, 25, 40 and 60 year based on data of the forest age in the catchment, gathered from the Swedish national forest inventory. Clear-cut lakes were classified as 5 years (>20% of the catchment clear-cut during the last 10 years).
Alumner från SLU, Skogsmästarskolan säger sitt
The purpose of this study is to investigate the forest managers view of the edu-cation at the School for Forest management at SLU and the first years of em-ployment. Surveys were sent to batches 05/08, 06/09 and 07/10 a total of 136 question-naires were sent out. 80 people answered the survey, this gives a response rate of 59 percent
The former students rated according to a 9-grade scale how satisfied they were with the different courses they had attended during their years as students at the school. The courses in mathematics and statistics got the highest marks with an average of 7.3, while the entry-level course in law only got an average of 4.6.
A major part of the former students had in the questionnaire enquired a leader-ship course and a business course with focus on negotiation techniques during their education.
There is a wide variety of employment opportunities for the graduated students. Timber buyers and forest managers or planners are just a few positions that for-mer students now possess.
The study shows that there is a big difference in the first introduction to a new work place depending on where the student got hired.
Urskogen med de stämpelbleckade gammeltallarna : en skogshistorisk tolkning av Brännlidens naturreservat
People have used forest resources in northern Sweden for different purposes. Before the 20th century the forest was used for many different reasons, but during the past 200 years it has become an industrial raw material. The presence of people in the forest has left different kinds of traces in the forests. One example is culturally modified trees (CMT´s). The aim of this study was to study and document how people have used the forest resources during the last centuries in Brännlidens nature reserve, and what kind of traces this land use has left.
Taktisk planering med geografisk hänsyn : fallstudie med Heureka PlanVis på SCA Skogs distrikt Liden
SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational.
The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.
Skogsbrukets framtida arbetskraftsförsörjning : skogsmaskinföraryrkets attraktionskraft
The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.
Skötsel av vägnära skog för trafiksäkerhet och naturupplevelse :
A great deal of the nature experience we get today is from travelling along our roads, which to a large extent go through the forest landscape. This makes the forest along our roads interesting to look at from a nature experience perspective. The main idea of this work is to increase the awareness of how we are affected by the forest when we travel through it and find out how the forest should be adapted to the road environment to create a pleasant nature experience as well as increase traffic safety.
0.9 % of Sweden's total forest area (equivalent to 200 000 hectares) is in close proximity to roads. Additionally, in Sweden 440 million hours are spent behind the wheel of which a great deal probably is spent on roads surrounded by forest in some form.
Uppfölining av naturvårdande skötselåtgärder(NS) i ekopark Storklinten
This study's primary purpose was monitoring of conservancy operation measures. The fixed sections within ekopark Storklinten owned by the forest company Sveaskog. These measures are performed with the purpose of creating and maintaining hardwood forest and mimic natural processes. The sections were divided into different categories depending on the type of measures they were exposed with. The monitoring showed that the purpose of these measures was fulfilled in general.
Possibilities for, and attitudes towards, a potential reintroduction of wild forest reindeer Rangifer tarandus fennicus Lönn. to parts of Sweden.
AbstractThe wild forest reindeer is a subspecies of the reindeer. Wild forest reindeer earlier had awide distribution range in Sweden, but it was extinct in the middle of the 19:th centurybecause of extensive hunting. In Finland, the w.f.reindeer was extinct a few decades later bysimilar reasons. Later they migrated back to the eastern parts of Finland in the middle of the20: th century. Around 1980, the w.f.reindeer was actively rentroduced to western Finland,and there the population has had a positive development.
Svenska hushålls vedarbete : en fallstudie i Umeåregionen
In Sweden there are 354 000 private individuals owning forest. Of these forest owners there are at least two thirds that are self-employed, which means that about 215 000 forest owners conduct some kind of work in their own forest. Those numbers do not refer to firewood production, but every year 7.3 million piled cubic meters of firewood are used for heating Swedish households. This implies that many households are also producing firewood.
The objective of this study was to assess and analyse the small-scale firewood production in the Umeå-region in terms of persons engaged in the work, equipment used, produced volumes and share of forest-owning households involved in these activities. According to results from a questionnaire, the average firewood producing person is a man between 40-60 years old.
Släktöverlåtelser av skog och jord i två byar i Sverige
The way to acquire forest in Sweden from parents has been unequal, men were prioritized over women, which was the traditional inheritance pattern. Research has made this clearer by using gender, which ?values? our stereotypes of sexes and can help us understand inheritance patterns. The gender determined who would inherit but also the form of ownership, praxis, property rights, regulations, power and work invested made by a sibling could influence. The purpose with my study was to find what conditions governed inheritance of forest on the properties I investigated and what influence gender had.
Hur bokskogslagen blev till ? konflikter och lösningar 1964-1974
During the early Middle Ages beech forests (Fagus sylvatica L.) spread out over large parts of southern Sweden. They had a crucial role in human survival for hundreds of years. For various reasons, the beech forest area has decreased since the 1600s. Spruce planted on former beech forest land was the primary reason for the decline during the second half of the 1900s, which made many worried about the future of the beech forests and led to a beech forest act in 1974. This study describes the background to the beech forest act based on parliamentary official documents.
Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län
The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.
Utveckling av en effektmätare för landsvägscykling
Over 90% of forestry work is carried out today by contractors, thereforeclear agreements between the client and the contractor it is of utmostimportance. Contract Packages for work within the forest sector (APSE) is acollection contract templates that the industry jointly developed for thispurpose. The purpose of this thesis is to examine how forest contractors doto keep themselves updated of the current laws and government regulations,which channels are available to accomplish this and what possible obstaclesmay occur. 20 interviews were conducted with contractors engaged inlogging. The results show, among other things, the availability of and whichchannels most contractors use out of which aggravating circumstances existand how strong they are perceived and what is expected of the client in thisregard..
Betydelse av lövinslag, död ved och variation i träddiameter för artrikedomen hos småfåglar
Forest management contributes to the changes in forest structure by turning heterogenous forests of varied age into homogenous forests of similar age and thus affect bird species depending on different structures or habitats which are lost during forestry. In this report, a study was made to investigate how the amount of decidious trees, dead wood and variation in tree diameter affect bird diversity. The purpose of this study was to be able to give forest management guidelines to increase bird diversity. This study was conducted by investigating 65 transects in forests of different structure south of Linköping, Sweden. Along the 65 transects, birds were inventoried as well as the vegetation.
