The Macroinvertebrate Community in a Nature-like Fishway with Habitat Compensation PropertiesGustafsson, Stina January 2012 (has links)
Nature-like fishways are often constructed to restore connectivity in streams exploited for hydropower. They also have the potential to compensate for important habitats that have been degraded or lost. The aim of this thesis was to improve knowledge of the concept of nature-like fishway design, with special focus on their habitat compensation potential. This was done by comparing a nature-like fishway with four different habitat types, termed the biocanal, to six nearby natural reference creeks. In paper I the macroinvertebrate colonization of the biocanal was studied and the community composition was compared to that of the natural reference creeks. Furthermore, the potential for the biocanal to contain a diverse macroinvertebrate fauna was investigated. The results showed that the species composition of the benthic fauna in the biocanal was approaching that of the reference creeks and that the different habitat types in the biocanal contributed to the increased family diversity. In paper II the functional organization of the biocanal was studied using the functional feeding group approach. The results showed that after two years, the functional organization in the biocanal resembles that of the natural reference creeks.

Jag trivs bäst när havet svallar, och måsarna ger skri : En textanalytisk studie av biologisk mångfald i läroböckerGranquist, Anna, Mårdfjäll, Eva January 2007 (has links)
Biological diversity is one out of four dimensions, characterizing the subject of Biology ac-cording to the school curriculum. As a concept, biological diversity had its break through at the UN environmental conference in Rio de Janeiro in 1992, where the convention about bio-logical diversity, named CBD, was signed. According to the convention, almost all the na-tions of the world have engaged themselves to preserve the national diversity of species, in-cluding the diversity of genetics and ecological systems. This thesis focuses the biological diversity from the perspective of school books. The aim is to find out how the biological diversity is presented in biology books for students aged 12-15 years. In 1994, the current Swedish secondary and high school curriculum called LPO-94 was pre-sented. The biology books used in this study were published between 1994 and 2007, all of them exist in many editions and are published by three different publishers. The conclusion of the study is that all the biology books that were examined have reached different levels of the development in the field of biological diversity.

Implementation of the European network: Natura 2000 : Determined according to overarching EU directives or through compromising ecological aspects?Westfahl Backlund, Martina January 2008 (has links)
Global biodiversity is currently being lost at an unprecedented rate, posing a threat to vital ecosystems and hence the generation of ecosystem services that human society is entirely reliant upon. Within the European Community, the EU has set a target of halting biodiversity loss within the territory by 2010. This goal is intended to be operationalized by the implementation of the Habitats Directive and the Birds Directive. These directives constitute the framework for the establishment of a coherent ecological network, referred to as the Natura 2000 network. This study examines and analyses the socio-ecological complexities surrounding the designation of Natura 2000 sites in Östhammar municipality, Sweden. The use of a case study-approach to focus on this area is applied in pursuit of identifying and explaining the inherent intricacies in the designation processes and linking them to the broader global context. Throughout Europe, biodiversity exists in a rich variety of grasslands, but only a few studies have been performed to establish appropriate conservation management strategiesrequired for each habitat. This study makes a significant contribution towards shedding light on the Natura 2000 designation process, a phenomenon which has previously been only modestly documented, especially in Sweden. Ecosystem management is discussed and utilized as the theoretical basis for managing ecosystems sustainably, and an important aspect of note is the recognition that the distinction between man and nature needs to be understood as artificial and arbitrary. The study explains how social-ecological factors have had a prominent effect on the designation process of Natura 2000 sites. The main determining factor behind the designation process has been the time-constraints, which have affected the designation of SCIs as well as the interaction between the Uppsala CAD and local stakeholders. The lack of adequate participatory approaches used during this process has heightened the risk of compromising the aim of the network: to achieve Favourable Conservation Status (FCS) for natural habitat types as well as species. / Biodiversiteten världen över minskar i en tidigare aldrig skådad hastighet vilket resulterar i ett hot mot fundamentala ekosystem, samt dess produktion av de ekosystemtjänster som det mänskliga samhället är beroende av. På grund av detta har EU satt upp målet att stoppa förlusten av biodiversitet inom unionens gränser tills 2010. Detta mål skall uppnås genom implementeringen av Habitat- och Fågeldirektivet. Dessa direktiv utgör ramen för etableringen av ett sammanhängande ekologiskt nätverk, det så kallade Natura 2000 nätverket. Denna studie utreder samt analyserar de socio-ekologiska aspekter som omger utpekandet av Natura 2000 områden i Östhammars kommun, i Uppsala län i Sverige. Genom appliceringen av en fallstudie av området söker denna uppsats att identifiera samt förklara inneboende svårigheter i processen av dessa utpekanden, samt att sätta dem i ett globalt sammanhang. Inom Europa existerar biodiversitet bland annat i olika typer av ängar, dock har endast ett fåtal studier tagit sig an uppgiften att formulera anpassade förvaltningsstrategier för dessa habitat. Denna studie bidrar till att sprida ljus över implementeringen av Natura 2000, ett fenomen som tidigare endast studerats i blygsam utsträckning, speciellt i Sverige. Den teoretiska grunden utgörs ekosystemansatsen, som appliceras för att utvärdera ett uthålligtförvaltande av ekosystem. Vidare understryks vikten av att betrakta ekosystem och mänsklig aktivitet som ett och samma system, och att synen på dem som skilda system bör anses artificiell och motsägelsefull. Denna uppsats förklarar hur socio-ekologiska aspekter har påverkat utpekandeprocessen av Natura 2000-områden i Östhammars kommun. De avgörande faktorerna bakom detta är en identifierad tidsbrist, vilket har influerat utpekandet av områden av gemenskapsintresse samt interaktionen mellan Länsstyrelsen i Uppsala och lokala markägare. Bristen på samverkan och information har resulterat i en förhöjd risk av att målet med nätverket inte kommer att nås: att åstadkomma gynnsam bevarandestatus för arter och habitat.

Evidence-Based Knowledge Versus Negotiated Indicators for Assessment of Ecological Sustainability : The Swedish Forest Stewardship Council Standard as a Case StudyAngelstam, Per, Roberge, Jean-Michel, Axelsson, Robert, Elbakidze, Marine, Bergman, Karl-Olof, Dahlberg, Anders, Degerman, Erik, Eggers, Sönke, Essen, Per-Anders, Hjältén, Joakim, Johansson, Therese, Müller, Jörg, Paltto, Heidi, Snäll, Tord, Solovity, Ihor, Törnblom, Johan January 2013 (has links)
Assessing ecological sustainability involves monitoring of indicators and comparison of their states with performance targets that are deemed sustainable. First, a normative model was developed centered on evidence-based knowledge about (a) forest composition, structure, and function at multiple scales, and (b) performance targets derived by quantifying the habitat amount in naturally dynamic forests, and as required for presence of populations of specialized focal species. Second, we compared the Forest Stewardship Council (FSC) certification standards’ ecological indicators from 1998 and 2010 in Sweden to the normative model using a Specific, Measurable, Accurate, Realistic, and Timebound (SMART) indicator approach. Indicator variables and targets for riparian and aquatic ecosystems were clearly under-represented compared to terrestrial ones. FSC’s ecological indicators expanded over time from composition and structure towards function, and from finer to coarser spatial scales. However, SMART indicators were few. Moreover, they poorly reflected quantitative evidence-based knowledge, a consequence of the fact that forest certification mirrors the outcome of a complex social negotiation process.

Creating Partnerships Between Governmental Authorities and Indigenous peoples: a New Strategy for Biodiversity ConservationDuboisset-Broust, Lauren January 2013 (has links)
Securing the interactions between plants, animals, microorganisms and the physical environment forms the foundation of sustainable development (Global Biodiversity Strategy, World Resources Institute, 1992). Facing the ongoing depletion of the natural resources, new strategies to ensure biodiversity conservation were developed. The establishment of protected areas by governmental authorities rarely led to successful results, in terms of environmental protection and social justice (Alcorn, 1993). A shift of thinking in the 1970s allowed the conservationists to see the indigenous peoples no longer as barrier to biodiversity conservation but as the holders of complex and historical knowledge of the natural environment. Consequently, partnerships were developed between governments and indigenous communities within the protected areas. This study investigates the results of the creation of partnership, whether it is a good means to achieve biodiversity conservation or not, and under which conditions it can be successful. It also aims to find the perceived benefits and potential limitation of cooperation. Through the analysis of two case studies: the World Heritage site in Laponia, Sweden and the Kaa-Iya del Gran Chaco National Park in Bolivia, the study finds that partnership for biodiversity conservation is utterly related to social and political claims: because a successful partnership cannot be imposed from above, a process towards indigenous peoples’ right to self-determination must be initiated.

Maple Sugar Bush Management and Biodiversity Conservation in Eastern Ontario, CanadaClark, Kristin 27 October 2011 (has links)
This thesis examines the extent to which sugar bush management in Eastern Ontario might contribute to biodiversity maintenance and conservation and therefore be promoted as a form of rural sustainable development. Ontario government policy seeks to actively promote actions that strengthen the province’s rural communities and protect biodiversity. Therefore sustainable development is an important concept to encourage in rural areas. The production of maple syrup on sugar bushes has already been demonstrated to be economically, socially, and in some aspects ecologically sustainable. This study seeks to determine how the operation of sugar bushes might also contribute to ecological sustainability through the maintenance and conservation of forest biodiversity.
I identified three documents published by the Eastern Ontario Model Forest (EOMF): a set of management principles for conserving biodiversity on private woodlots, a list of biodiversity indicators, and a manual for monitoring them. I monitored three of the biodiversity indicators (spring ephemerals, birds, and frogs) on three of the larger sugar bushes in the Eastern Ontario and established that the EOMF biodiversity monitoring practices and guidelines were suitable for working sugar bushes. Using the management principles for biodiversity conservation developed by the EOMF, I interviewed 22 sugar bush operators in Eastern Ontario. With these interviews I addressed two objectives:
1. To generate empirical information regarding the management practices of maple sugar bush operators in Eastern Ontario and to compare these with established management principles for forest biodiversity conservation in the region
2. To generate suggestions for woodlot operators and government policymakers alike about future opportunities for research and management decision-making.
The results of the study show that although most operators do not have a formal management plan for their sugar bush, many of their management practices are consistent with prescribed biodiversity conservation principles. Sugar bush operators are receptive to conserving biodiversity on their properties. The findings suggest that through sound management and planning, small-scale commercial sugar bush operations generally can be made environmentally sustainable, and become important components in broader rural development strategies.
This study provides new insights into how small-scale sugar bush management, when practiced well, is consistent with conservation principles and with sustainable development principles more generally. It shows how sugar bush operators in Eastern Ontario can help the province reach its goals of biodiversity conservation and rural development set out in Ontario’s Biodiversity Strategy (2005) and Ontario’s Rural Plan (2004).

Naturhänsyn på slutavverkade hyggen i Östergötlands län.Jonsson, Sofia January 2011 (has links)
95% of the productive forest land in Sweden are now being exploited for forestry. The new Forestry Act of 1993 equate the goal of production and the environmental goal which means that the objective for forestry is a sustainable yield, while the biological diversity must be preserved. Recent years results from the inventories of the Board of Forestry show declining trends in how nature conservation aspects taken into consideration at the felling sites.The aim of this study is to investigate what happends with the nature consideration taken at felling sites in the long run. 20 final fellings in the county of Östergötland were re-inventoried 7-9 years after final felling. These felling sites had previously been inventoried before final felling (P0) and one year after final felling (P1) in the inventory Polytax by the Board of Forestry. On 18 of 20 felling sites nature consideration had decreased significantly from P1 inventory to re-inventory. Retention trees had declined the most, 7.9% of the total volume of retention trees was gone. Taking conservation in to consideration at final felling sites by retenetion of trees and habitats with high conservation value is an important step in preserving biodiversity and increasing the chances of survival for the species considered sensitive to forestry. In order to improve the consideration of nature and thereby increase the chances of species survival a functional follow-up of conservation efforts at the felling sites is required.

Deforestation Impacts on Biodiversity Conservation in the Dja Biosphere Reserve of CameroonOke, Ndum Fidelis January 2009 (has links)
Abstract The tropical rainforest of the world are very important for the global ecosystems. Most of the remaining rainforest in Africa is concentrated within the Congo Basin forest area. The Congo basin rainforest is second that of the Amazon basin and with the Indonesian forest are the most important rainforest in the world. The Dja Biosphere reserve which is located in the South Eastern part of Cameroon forms the upperparts of the Congo Basin Forest. Despite the fact that this area is a natural reserve implying that certain human activities like cutting down of forests around the buffer zones and hunting without permission are outlawed, we notice that there is increasing damage being done to this reserve especially around its periphery. The study aimed at examining the impact of deforestation activities on the Dja biosphere reserve to see if the exploitation is in a sustainable way or not. It also aimed at looking at the importance of the reserve to local communities who live around the area, the reasons for exploitation and the impacts, which stakeholders and what roles they play, and finally to find a better management strategy for the future. To be able to meet the objectives, the study was mostly analytical using carefully selected data to illustrate the problem and showed loopholes in policies. Suggestions for better management were made after looking at certain theories (Triple bottom line concept, Adaptive environmental planning, and Market instruments of Charge and Permit systems) and their possible applications. The study showed that the reserve was still 90% untouched but that some species were endangered even though none was critically under threat. It also showed that some species were conservation dependent and the reports of threats were increasing. Also, it was noticed that the reserve was very important to local populations not just as a means of subsistence but also as a way of increasing their household incomes. Recommendations are made with regards to the consideration for autonomous management, increase public participation in decision making and enforcement, and the creation of a special fund for collected charges from logging companies so that the funds can be used to increase conservation efforts. It is very necessary to increase conservation efforts as a precautionary step than to wait for the level of degradation to increase before taking action.
