Biodiversity is the prerequisite for well-functioning ecosystem services that are crucial, like clean water and clean air. Invasive alien species (IAS) are a serious and long-term issue that is actively threatening the genetic diversity within ecosystems. In Sweden, 20 percent of 2000 alien species is estimated to be invasive or potentially invasive. One of the species that is assessed to be an IAS is garden lupine (Lupinus polyphyllus), which today is widely spread over big parts of Europe and it is established and reproducing in Sweden. The aim of the study was to find out wether the occurence of garden lupine in Jämtland (last 30 years) has an association with a certain type of land cover and soil moisture, and wether reported findings have increased over the years. This analysis was carried out by first statistically testing the association between the number of lupine observations and the reporting year. After that, a 5m-radius buffer was created around the reported species observations, to then compare the area of each class from National Land Cover Database (NMD) and SLU Soil Moisture Map within the buffer against the total area for each class within Jämtland County. The results of the study showed that the occurence of garden lupine can be associated with the type of land cover and soil moisture that is found on the place of occurence, and that the reports of occurence has increased over the years. The area of the land cover classes within the buffer was not proportional to the total area of those classes in Jämtland County. Lupine occured most commonly within land cover classes exploited land (50%; mainly "exploited land road/railway"), forest (30%), and other open land (20%). As for soil moisture, the garden lupine was only observed within two classes, and the area for these classes within the buffer was not proportional to the area of the same classes in Jämtland County. The soil moisture class with the highest percentage of reported occurence was the class "mesic-dry". These results are in agreeance with the literature describing nonnative habitats for garden lupine, however they do not reflect the facultative status it has received in native habitats. The spread of garden lupine can in other words be linked to the land cover and soil moisture that is found in the place of occurence. Future efforts that are needed are continous monitoring of garden lupine, harmonization of data through standardized inventory methods and validation of data. / Biologisk mångfald är förutsättningen för att avgörande ekosystemtjänster som rent vatten och ren luft ska fungera väl. Invasiva främmande arter (IAS) är ett allvarligt och långsiktigt problem som aktivt hotar den genetiska variationen inom ekosystem. I Sverige bedöms 20 procent av de 2000 främmande arterna vara invasiva eller potentiellt invasiva. En av de arter som klassas som IAS är blomsterlupin (Lupinus polyphyllus), vilken idag är vitt sprid över stora delar av Europa samt är bofast och reproducerande i Sverige. Syftet med studien var att ta reda på huruvida förekomst av blomsterlupin i Jämtland över 30 år har ett samband med viss typ av marktäcke och markfuktighet, samt om inrapporterade fynd har ökat med åren. Denna analys genomfördes genom att först statistiskt testa sambandet mellan inrapporteringar och rapporteringstillfälle. Därefter konstruerades en buffert med en radie på 5 meter runt inrapporterade artobservationer, för att sedan jämföra arean av respektive klass från Nationell Marktäckedata (NMD) och SLU Markfuktighetskarta inom bufferten mot den totala arean av respektive klass i hela Jämtland. Studiens resultat visade att blomsterlupinens förekomst kan associeras med vilken typ av marktäcke och markfuktighet som finns på platsen, samt att inrapporteringen av arten har ökat över åren. Arean av markatäckeklasserna inom bufferten för artobservation var inte proportionell mot den totala arean av respektive markatäckeklass i Jämtlands län. Lupin förekom vanligast inom marktäckeklasser exploaterad mark (50%; framförallt ”exploaterad mark väg/järnväg”), skog (30%) och övrig öppen mark (20%). Vad gäller markfuktighet så observerades endast blomsterlupin på två klasser, och arean för dessa klasser inom bufferten var inte proportionell mot arean för samma klasser i Jämtlands län. Markfuktighetsklassen som hade störst procentuell andel av inrapporterade fynd var klassen ”torr-frisk”. Dessa resultat överensstämmer med litteraturen som beskriver icke inhemska habitat, däremot reflekterar inte dessa resultat den fakultativa statusen som blomsterlupin har fått i dess inhemska habitat. Mina resultat visar att blomsterlupinens utbredning kan kopplas till den marktäcke och markfuktighet som finns på fyndplatsen. Framtida insatser som behövs är fortsatt övervakning av blomsterlupin, harmonisering av data genom standardiserade inventeringsmetoder och validering av data.

The area above Labyrintgrottan was most likely covered by much denser vegetation than today at the time of stalagmite growth (9500-7500 years ago) and was, unlike today, probably situated below the local tree-limit between 9000 and 8000 years ago. The δ¹⁸O record of a stalagmite from Korallgrottan covering the last 4000 years agrees with the concept of a warmer period, the so called Medieval Warm Period, centred around AD1000 and a colder period, the so called Little Ice Age, somewhere between AD1000 and today.</p><p>Studies of luminescence properties in fast growing speleothems from Uppsala indicate that the variations in luminescence intensity are annual and that the annual lamiae of the luminescent record represent a flush of organic material.</p>

Detta är en ekokritisk studie av Kerstin Ekmans samhällsrealistiska roman Händelser vid vatten (1994). Dramat utspelar sig mellan år 1970 fram till 1990-talet i byn Svartvattnet som ligger i norra delen av Jämtland. Ekman beskriver folkets relation till skogen i bygden, och vad som sker i och med tillämpningen av storskalig skogsavverkning med stora kalytor som följd.

The aim of this study was to investigate and analyze what is required for the environmental quality objective Good built environment to be fulfilled by 2020 in the Swedish county Jämtland. The focus of the study was to gain an understanding of the work that the local government does and further investigate the problems that the officials face with implement these questions in themunicipal planning. The study is based on semi structured interviews with officials in the municipalities of Jämtland county. General plan and programs for the municipality have been reviewed, based on how the plans highlights these issues linked to sustainability and Good built environment. The results of the study show that there are major problems with the formulations of the environmental quality goal in itself and its specifications. The environmental quality goal is formulated to suit the entire Sweden. But as it turns out in the analysis it does not work on the basis of the conditions inJämtland with sparsely populated areas and scattered dwellings. The environmental quality goal needs to be formulated after the conditions that the county has to be measured and fulfilled by 2020. The officials agreed that a regional vision is needed, adapted to Jämtland conditions.

This essay is about two areas called Hackås and Myrviken, situated in the middle of Sweden around the lake Storsjön. In Hackås we can see traces after an early agrarian settlement, and in Myrviken we find Jämtlands largest concentration of ironmaking sites from around 400 AD. There are no clear evidence of the agrarian settlement in Myrviken, and only two ironmaking sites in Hackås. These two economies functioned at the same time, but were clearly separated. My purpose is to discuss if it was the farmers of Hackås who made iron in Myrviken, or if it was somebody else.

Local participation in nature conservation has gained more attention over the last decades due to international conventions as well as local and national initiatives. This development can be seen as a reaction to a more expert oriented nature conservation characterized by centralized control and strict preservation of so called "original" nature. The overall objective of this thesis is to contribute to research on new forms of conservation where democracy and local participation is included. The case study focuses on the process of producing a pre-study for a suggested national park in southern Jämtland in the Swedish mountain region, and aims to investigate to what extent local participation was included. The pre-study was led by the Swedish Environmental Protection Agency (SEPA) and the County Administrative Board (CAB) in Jämtland. The thesis is to some extent grounded in a political ecological perspective, which highlights connections between politics, societies and the environment. The methods used are semi-structured in-depth interviews and literature studies. The results show that although the stakeholders interviewed to some extent share views on the process, there are also differences. The SEPA and the CAB are generally satisfied with the result while there is some dissatisfaction among others. However, all stress that respect and dialogue are important and most actors see zoning and channeling within a potential park as part of a solution to past conflicts in the area. How the management structure will take form and to which extent it will include local participation has not been discussed in detail so far, although the Sámi demand to be included in any future management. These questions will be further investigated by the SPEA if they decide to proceed in a national park process. / Bortom konflikter: utmaningar och möjligheter i svenska fjäll

Objective of this thesis is to identify potential energy savings regarding engine heating of cars within the Jämtland-Härjedalen county, northern Sweden. This could contribute to energy consumption reduction goals of Sweden. Potential energy savings are defined by comparing the current energy consumption with the energy consumption of different energy saving scenarios in terms of behavioural change and technological choices. Energy consumption, both current and potential is modeled in excel based on data derived from quantitative investigation and literature review. Engine heating is identified as an energy consumer, the energy saved by fuel consumption reduction (7,77 TJ/year) does not overcome the invested energy to heat engines (26,36 TJ/year). Engine heating reduces engine wear, fossil fuel consumption (0,34 TJ/year) and emissions currently. Regarding the choice of technology using more automatic time adjustment reduces energy consumption, engine wear, emissions and fossil fuel consumption. Other scenarios show a compromise between energy consumption reduction on one side and fossil fuel consumption reduction in combination with reduced engine wear and emissions on the other side.

Immigrant-receiving societies emphasize the need for immigrants to integrate intomainstream life. In Sweden, this trend has manifested itself in integration policies. Inthe present study, the author aims to understand sports and outdoor events experienceand its effects on social integration of immigrants and refugees’ in the JämtlandCounty, Sweden. By ‘giving voice’ to 19 participants from different nationalities, thisstudy explores the new Swedes’ perspectives on social integration process andconceptualizes their engagement and experience of sports and outdoor eventsthroughout this process. The participants speak of the benefits and needs to participateactively in the society of settlement, but they also describe the barriers and obstaclesthat they may face. Their perception of integration is based on their life stories andexperiences. Based on findings and results, three descriptive themes are described.The outcomes of three descriptive themes are interpreted in one overarching themeelaborating the role of sports and outdoor event as a social connection leading to socialintegration of newcomers. It is assumed that sports and outdoors are not strongenough to achieve social integration, rather they can act as social bridges and providea common ground where integration can be cultivated. The results of this study canbe useful for the sports and events planners and organizers specifically in 2021 whichis appointed as ‘Friluftslivets år 2021’ (Year of outdoor life) as well as those who dealwith newcomers’ integration in Sweden and Jämtland. / <p>2021-02-01</p>
