Kulturarv för evigheten? Studie av kyrkans utveckling och framtid med exemplet Skallsjö kyrka
The aim of this study is to describe and analyze the history and the current situation of the Church of Sweden. The renovation of Skalljö church in Lerum municipality has been used as an example to enlighten the common changes in the church buildings. The long history of the Church of Sweden as the state church has resulted in the fact that it carries a remarkable part of the Swedish cultural heritage. The reason why the Heritage Conservation Act (1988:950) was altered in January 2000 was due to the change of relations between the State and the Church of Sweden. According to the Act, all church sites owned or managed by the Church of Sweden shall be maintained in such a way that their cultural historic value is not diminished and their appearance and character are not violated.Sweden is today considered to be a secularised country where religion is an individuals? private matter.
Hur kan naturvärden och rekreativa intressen tas tillvara vid byggnationsprojekt? : Fallstudie Tyresö strand
Under det senaste årtiondet har 97 % av den totala folkökningen tillkommit inom fem kilometer från kusten, främst kring storstadsregionerna. Tyresö kommun är en av Stockholms förorter. Kommunen har under åren köpt loss tomter i ett kustnära område vid Tyresö strand. Ekologigruppen ab har på uppdrag av kommunen gjort bedömningar av områdets naturvärden såväl som rekreativa värden. Bedömningarna är tänkta att kunna vila som beslutsunderlag för planering såväl som byggnationer i området.
Aktör - Struktur : Förslag till utgångspunkt för studier av samverkansprocesser i förvaltningsområden med naturresurser
The focus on this essay is derived from an international and national dialogue for sustainable development. The recommendation from international level has been to find solutions for governments to implement strategies for sustainable development between local and regional level. This initiative is to improve and stimulate the dialogue between the local inhabitants, officials, entrepreneurs and stakeholders in the communities together with the authorities on the regional level. The purpose is to share knowledge and find ways to learn about the natural systems and how to co-operate in the work of preserving the natural resources and developing different processes for a sustainable development. Many scientists? today stress the importance that ecosystem resilience is promoted by biodiversity conservation and that we need to find solutions for local ecosystem management practices.This essay aims to find theoretical approaches and perspectives that can be used in a wider framework to study co-operative processes between the local (agent) and regional (structure) level.
Bokhögstubbar i Klåveröds strövområde : utbredning, egenskaper och betydelse för rödlistade vedlevande skalbaggar
Lack of dead wood is the main cause of decaying or loss of populations for many
forest species. To increase the amount of dead wood is a prerequisite to maintain
biodiversity in forests of northern Europe. In summer 2006 the recreation area
Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps
(snags) of beech, (Fagus sylvatica). The result of the inventory has been compared
with data of the real estate and forest management directories from the owner,
region Skåne. The results have also been matched with the results from an
inventory of saproxylic beetles in 2005, performed with windowtraps on selected
snags both in the area and the adjacent national park Söderåsen.
594 snags were found on 747 ha.
Lek hos Stinkpadda (Bufo callamita): jämförelse av restaurerade och ickerestaurerade hällkar
The natterjack toad (Bufo calamita) is one of three species of toads living in Sweden. During the last decades declines in population numbers have been detected and are thought to be primarily due to loss of habitat, overgrown breeding ponds and competition from common toad (Bufo bufo) and common frog (Rana temporaria). In 2012 20 ponds in the location of Glommeskallen in Smögen were restored by clearing the ponds from overgrowth. The aim of this study was to investigate if natterjack toads used the restored ponds and if the restoration had made an impact on the natterjack population on the location. Presence of common toad and common frog was recorded, as was the presence of eggs and larvae of any of the three species.
Ljudlandskap i kulturmiljöer
This bachelor thesis aims to draw attention to sound in the heritage sector in Sweden. In particular, to thesoundscapes that can be identified in our cultural heritage environments. Sounds in an environment, here calledsoundscapes, affect our perception of the environment and how we remember it.To find out how the heritage sector uses and would be able to use sounds, I have firstly studied if audio recording iscomparable with the visual photographic image. I then present examples of sound documentation concerning theconservation of built environment. In addition, I have interviewed five key informants who all have a centralresponsibility for five cultural heritage environments.
Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?
Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.
Igensättning av långsamfilter i Östby vattenverk i Kramfors : studie av påverkande faktorer
Östby waterworks in the community of Kramfors has since 2003 had problems of fast clogging of the slow sand filters. As the clogging appears more often, they must be cleaned more frequently which has made the drinking water preparation difficult. Wintertime it has sometimes been impossible to clean the filters which has led to their closing and this has influenced the water quality negatively.The waterworks is a surface waterworks which takes its raw water from the lake Sjöbysjön. The water is flocculated and filtered in a contact filter with the flocculent EKOFLOCK 91. Thereafter it is alkalinized before it reaches the outdoors placed slow sand filters.
Kulturmiljövärden utan synintryck, en studie med synskadade
This graduate thesis takes its hold in an idea that many values, in cultural heritage environments, other than the onesthat can be seen with the eyes are as important for the experience of the environment as the visual ones; however theenvironments are usually defined by values that can be experienced visually!Interviews were held with four visually impaired persons. This to get a better understanding for how big part othersense modalities play in the experience of the cultural heritage environments. Questions were asked about what thevisually impaired especially value in cultural heritage environments and what is of value for preservation. Also whatcan be done to make the environments more impressive for them, how they experience the material part of theheritage, architecture, shape and color and with what senses they primarily remember. Furthermore the thesis aims todraw attention to how value definitions made by the conservation field affects the experience of the environmentsand therefore the accessibility for visually impaired.
Omkonservering av Vattendr?nkt L?der Analys och Metodutveckling f?r Vasaskeppets L?derartefakter
In the collections of the Vasa Museum, 100 leather objects have exhibited salt precipitations. The objects,
that have previously been impregnated with PEG, have become deteriorated and fragmented due to the
precipitations. During a previously conducted study it was established that the precipitations consisted of
iron and sulphur. However, it was not established whether they occurred in the leather?s inner structure
and no treatment plan was developed.
Förvaltning och skogsskötsel av ett tätortsnära naturreservat : en fallstudie om Lugnets naturreservat i Falun
Naturens betydelse för människan är stor och den tätortsnära skogen utgör en viktig plats i den växande urbana befolkningens närhet. Ungefär två kilometer nordost om Falu centrum ligger Lugnets naturreservat, ett tätortsnära område som nyttjas av allt från motionärer och barnfamiljer till elitidrottare. Syftet med den här studien var att genomföra en syntesanalys över hur skötseln av Lugnets naturreservat kan utformas för att tillgodose så många intressen som möjligt. Genom kvalitativa intervjuer med ett urval av områdets intressenter kartlades deras nyttjande och synpunkter. Tillsammans med befintlig teori inom området utformades generella och specifika skogsskötsel- och förvaltningsförslag för reservatet.
Människan i urskogen : vegetationshistoria i Hamra nationalpark under 2500 år
Pollen analysis of a peat core was used to reconstruct the last 2500 years of vegetation history, with focus on the impact of anthropogenic disturbance, in Hamra National Park, central Sweden. In addition, analysis of pollen in soil samples was performed in an attempt to locate ancient cultivation plots in the National Park.
The analysis of the peat core shows a development of the vegetation that can be divided into four stages of different degrees of human impact: A - virgin forest (c. 500 B.C.-A.D. 1300), B - grazed forest (c. A.D.
Skillnader i kungsörnens (Aquila chrysaetos) flyttningsmönster beroende på ålder och klimatfaktorer : En studie för skyddet av kungsörn
This study examines the factors that influence the seasonal movements of Golden Eagles (Aquila chrysaetos), and can thus provide important information that helps to improve the protection of the species. There were two main purposes of this study. First, I wanted to analyze the difference between preferences of juvenile and adult Golden Eagles in their choice of southern or northern hibernation areas. Do younger eagles prefer moving longer distance to southern areas of Sweden? Second, I wanted to investigate how the climate influenced the choice of date of migration in the fall.
Stabilisering av insektsangripna möbler : en jämförande studie av konsolidanter
Denna rapport är en jämförande studie av utvalda konsolidanter som används till att stabilisera nedbrutet insektsangripet trä. Av de trägnagande skadeinsekter vi har i Sverige är det främst den strimmiga trägnagaren som är intressant i möbelsammanhang. I rapporten beskrivs den strimmiga trägnagaren, en liten skadeinsekt som kan åstadkomma stor skada om den får verka ostörd. Insekten finns utspridd i hela Europa och är ett stort problem då den angriper alla typer av träslag. Nedbrutet insektsangripet trä förlorar sin styrka och kan behöva konsolideras genom att injicera konsolidanter in i träet.
