Nyckelbiotoper - urskogsrester eller kulturprodukter? : beståndshistorik i tolv nyckelbiotoper i Lycksele kommun
Since 1993 the Swedish Forestry Administration conducts a nation-wide inventory of wood-land key habitats covering all forest land in Sweden. The inventory aims at mapping and describing habitats where redlisted species occur or can be expected to occur. According to the inventory stand history is crucial to the presence of red-listed species. However, the current knowledge of stand history in woodland key habitats is very limited.
The purpose of this work is to describe stand history in woodland key habitats, i.e. fire history, human activities - mainly cuttings - and structural changes.
Jämförande livscykelinventering
This bachelor?s degree thesis was conducted in mechanical engineering at Halmstad University during spring semester 2010 in close collaboration with the company Gremo AB, located in Ätran, Sweden. Gremo AB produces, developes and sales forest machines in both Sweden and on the international market.Gremo AB belongs to one of the market leaders in forest industry, especially with their forwarder. In order to become a market leader even with their harvester, the company decided to change the harvester to have a swivel and a leveling driver cabin.The aim with this bachelor?s degree thesis was to develop a design concept for the harvester driver cabin, which Gremo AB can apply on the new harvester.
Det sköna landskapet : med antroposofin som inspiration
Det finns inget som specifikt kan benämnas som antroposofisk landskapsarkitektur. Dock bidrar den antroposofiska helhetssynen till en omsorg om landskapet och en förkärlek att tydligare visualisera samband. Man menar att människan måste ta ett högre moraliskt ansvar för sin omvärld och tänka i kretslopp istället för avfall. Samtidigt finns inom antroposofin en ständig medvetenhet om de estetiska aspekterna på såväl detaljnivå som i det övergripande landskapet. Läran grundades av österrikaren Rudolf Steiner i början av 1900-talet, mycket av hans tankar var vidareutvecklingar av Johann Wolfgang von Goethes filosofier.
Mångbruksplan Äspinge 2:2
This plan of multiple-use is made on the private owned forestproperty Äspinge 2:2 in the middle of Skåne.
The term ?multiple-use? came to Sweden in the beginning of the twentieth century and has slowly grown until about 30 years ago when the laws of nature conservation and sustainability was written into the forest law. The so called ecoturism got more and more popular and people began to seek space and silence in difference to the life in the highly populated areas. This also encouraged foreign tourists to come to Sweden. Mostly danish, german, and dutch people.
Commercial thinning and its potential for contribution to the timber supply in British Columbia?s Interior forests : a look at Finnish and Swedish forest practices and their applicability in British Columbia?s Interior forests
Thinning is the partial removal of trees in a forest stand prior to final harvest. The term can be divided in pre-commercial thinning where little if any volume is removed from the stand and commercial thinning where removals are intended to provide a positive economic result. From a silvicultural point of view, the goal of thinning is to enhance future crop tree quality by removing low-quality stems and providing sufficient space for the accelerated development of retained ones (Huuskonen & Hynynen, 2006).
The goals of this study was to see if commercial thinning could positively affect the short and medium term timber supply (MTTS) in the Interior regions of British Columbia (BC), and whether or not Scandinavian forestry practices could be adopted in the BC context. The mountain pine beetle (Dendroctonus ponderosae Hopkins) has created significant forest planning problems in BC. The annual allowable cut (AAC) was raised to capture beetle-killed timber while still merchantable.
Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd
Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT.
The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.
Investment in project preventing deforestation of the Brazilian Amazonas
The aim of this thesis is to create an understanding of the incentives for forest companies to invest in reducing carbon dioxide emissions from deforestation and forest degradation, which is termed REDD. The Brazilian Amazonas was chosen as the base for the investment case. Brazil has the largest area of rainforest in the world, and also the biggest problem with deforestation. The Amazon region of Brazil comprises rainforest which is largely intact and unexploited. Accordingly, there is significant potential scope for prospective investments in a REDD-project, and so have a noteworthy impact in preventing deforestation.The research approach used the United Nation?s Clean Development Mechanism concept was used as a framework for ascertaining the investment costs in potential REDD-projects.
Förskolors inställning till och användning avstadens natur :
This master thesis is made in co-operation with the Department of Forest Management and Products at the Swedish University of Agriculture in Uppsala and the Forestry Association in Stockholm. The purpose of the Master thesis was to describe how pre-schools in Sweden use forests and green areas, and to understand how different factors can affect the use of the nature. The purpose of the interviews was to create a picture of attitudes and routines of the pre-schools, in the matter of visiting the nature. The thesis is built on interviews where fifteen pre-schools in five large cities around Sweden participated. Among these pre-schools, five of them worked with special focus on nature, while the other ten did not have any particular focus connected to their activity.
Återförvilda Sverige?: En studie av rewilding som strategi för att bevara kulturlandskapet och gynna biologisk mångfald
Through millennia, humans have shaped the European landscapes. Agriculture, hunting andforestry have influenced virtually every ecosystem on the continent and formed what we todaythink of as the cultural landscape; a mosaic pattern of cropland, fields, pasture and forests. Thepast two centuries, globalization, industrialization and urbanization have come to pose a threatto the existence of these landscapes. European farmlands are now being abandoned at analarming rate, and the associated loss of landscape preservation, biodiversity and ecosystemservices is a concern to the scientific community and public alike.This thesis studies if the implementation of the relatively new conservation strategy rewilding(recreating self-sustaining ecosystems and reintroducing keystone species) can be a part of thesolution to preserve cultural landscapes and biodiversity in Sweden. Through interviewssupplemented with studies of published works, expertise from different fields has beencompiled to provide an overall picture of the capacity of rewildings as conservation method.
Epixylic lichens and bryophytes in young managed forests : substrate preferences and amounts of dead wood
Dead wood is important for many species. The amount of coarse dead wood (diameter >10 cm) is much lower in managed forest than in unmanaged forests. Stumps constitute the largest proportion of the volume of coarse dead wood in managed forests. Since stump harvest for biofuel may increase, the amount of dead wood will decrease even more, which may threaten biodiversity. The first aim of this study was to compare the amounts of fine woody debris (FWD, .
Gestaltning och förverkligande av Icehotels utemiljö säsongen 2009/2010
This paper constitutes graduate work at the landscape
architecture program at the Department of Urban
and Rural Development at the Swedish University of
Agricultural Sciences, Uppsala. The main purpose of this
paper is to create a project from an idea to reality. The
place for the project is the environment of Icehotel in
Jukkasjärvi in the north of Sweden. Icehotel is a unique
hotel concept and each winter a hotel, a church and a
bar is built at the area of only ice and snow, and each
spring it all melts down and returns to the Torne river.
During the project a plan for the environment, in ice and
snow, will be made and then a part of it will be built in
January 2010. The purpose is to improve the outdoor
environment with landscape architecture to enhance the
experience of Icehotel and create an exciting entrance to
the area.
Små skogliga vattendrag i Värmland - Generell beskrivning, förekomst av traktorspår samt spårens inverkan på bottenfaunan :
Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.
Re-design of Toledo Riverfront : from industrial past to sustainable biodiverse future
Effects of climate change, urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient
urban biotopes which also can be used by local urban communities.
The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design
competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields.
In my proposal I applied ecological design principles on three scales:
the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged
material.
Utsikt från höghastighetståg : om reseupplevelsens krav på landskapet
As we travel more and more by train it becomes increasingly important
that the time we spend traveling, is of great quality. This has been the foundation of this master thesis and has shaped the outcome of it. The traveling experience, that is, the experience of the landscape that flashes by outside the train window, is an important aspect in railway planning and an aspect that should be taken into greater consideration. The purpose of this master thesis has been to examine how to compose or improve the travel experience for an already planned high speed railway and how the travel experience can be combined with other aspects, which have claims on the landscape. This thesis is based on a literature study and a case study of Ostlänken.
The work describes Ostlänken, a planned high speed railway in Sweden between Järna and Linköping, with top speeds at 300-320 kilometers per hour.
