The effect of native forest dynamics upon the arrangements of species in oak forests-analysis of heterogeneity effects at the example of epigeal arthropodsLanger, Marco January 2011 (has links)
The heterogeneity in species assemblages of epigeal spiders was studied in a natural forest and in a managed forest. Additionally the effects of small-scale microhabitat heterogeneity of managed and unmanaged forests were determined by analysing the spider assemblages of three different microhabitat structures (i. vegetation, ii. dead wood. iii. litter cover). The spider were collected in a block design by pitfall traps (n=72) in a 4-week interval. To reveal key environmental factors affecting the spider distribution abiotic and biotic habitat parameters (e.g. vegetation parameters, climate parameters, soil moisture) were assessed around each pitfall trap. A TWINSPAN analyses separated pitfall traps from the natural forest from traps of the managed forest. A subsequent discriminant analyses revealed that the temperature, the visible sky, the plant diversity and the mean diameter at breast height as key discriminant factors between the microhabitat groupings designated by the TWINSPAN analyses. Finally a Redundant analysis (RDA) was done revealing similar environmental factors responsible for the spider species distribution, as a good separation of the different forest types as well as the separation of the microhabitat groupings from the TWINSPAN.
Overall the study revealed that the spider communities differed between the forest types as well as between the microhabitat structures and thus species distribution changed within a forest stand on a fine spatial scale. It was documented that the structure of managed forests affects the composition of spider assemblages compared to natural forests significantly and even small scale-heterogeneity seems to influence the spider species composition. / Um die Anpassungsfähigkeit von Organismen, bei sich ändernden Umweltbedingungen, sicher zu stellen, spielt die Erhaltung der Biologischen Vielfalt auf allen ökosystemaren Ebenen eine entscheidende Rolle. Eben diese Anpassungsfähigkeit kann durch waldbauliche Maßnahmen einschränkt werden, und zur Instabilität des Systems führen. Daher kommt der Untersuchung von aus der Nutzung genommenen Naturwaldzellen eine immer größere Bedeutung zu. Einerseits um die potentiell natürliche Diversität in Naturwäldern mit der in Wirtschaftswäldern zu vergleichen, andererseits um die ökologischen Zusammenhänge in einer natürlichen Waldentwicklung zu verstehen.
Ziel diese Studie war es eben diese natürlichen Waldynamiken auf das Artengefüge von Spinnen (Araneae) zu untersuchen. Dabei sollte Mithilfe eines experimentellen Fangdesigns, auch der kleinräumige Einfluss von Strukturheterogenität untersucht werden.

Management of Natural Stands of Acacia seyal Del. variety seyal (Brenan) for Production of Gum Talha, South Kordofan, SudanHamed Mohammed, Mohammed 29 June 2011 (has links) (PDF)
The present study was conducted in Umfakarin natural forest reserve, South Kordofan, Sudan. The main objective was to investigate the possibility of managing Acacia seyal Del. variety seyal for the production of gum talha. Three stand densities (strata), namely dense, medium, and slight, were distinguished based on the number of trees per hectare. During the sampling phase, the study adopted the method of identifying the competitors (neighboring trees) from the subject one (trees selected for gum production experiments). From the three stand densities, a total of 482 subject trees, covering variable diameter ranges (d= 9-11.5, 13.5-16, 18-20.5 and above 21 cm) were selected, based on the diameter at 0.25 m height (d0.25). In each stratum, competitor trees were identified within a radius equal to the height of subject tree multiplied by a factor (1.25). The diameter at breast height, height to crown base, height, crown radii, and tree coordinates were measured for each of the subject trees and its competitors. Subject trees were exposed to tapping on first of October, the fifteenth of October, and the first of November, using local tools (Sonki and Makmak). Additionally, untapped trees were used as controlling-variables. The initial gum collection was completed fifteen days after the tapping, while the subsequent (7-9 pickings) were done at an interval of fifteen days.
Six stand height functions were tested and the results illustrated that the Michailow stand height function was suitable for predicting the height of Acacia seyal in Umfakarin natural forest. The predictive ability of this height function ranged from 19.3% to 24%. The volume function used in this study was able to predict the volume of standing trees with more than 92 percent accuracy.
Competition among trees of Acacia seyal was assessed in terms of competition indices. Eight competition indices were quantified using the CroCom program. The relationship between these indices and tree dimensions (diameter at breast height, height and crown diameter) was tested using logarithmic models. Among these indices, the Hegyi_2 index is considered a suitable index to be applied for estimating the degree of competition in natural stands of A. seyal of dense stratum when using diameter at breast height as a predictor. About 70% of the total variability is explained by this logarithmic model.
Gum yielded by each subject tree per season was obtained by summing up the gum samples collected from all pickings. Gum production per unit area was also determined. Regression tree, general linear model (GLM) and logistic regression techniques were used for analyzing the obtained data. The results of the study indicated that the gum yield is independent of stand density. Tapping has influence on gum yield. Trees tapped by sonki on the first of October at medium stand density have the highest gum with an average value of about 56 g/tree/season. Significant difference (p = 0.021) was detected between two groups of dates; the first of October and first of November in medium stand density. The results also revealed that the most important variable influencing gum production was found to be diameter at breast height with 23.95 cm threshold. Between 41-53 percent of subject trees produce gum less than 50 g/season. The results indicated that A. seyal species produces a very low quantity of gum talha (3.6-4.8 kg/ha) and for economic reasons, its tapping is not recommended. The findings of the regression analysis revealed to a model which could be used to estimate the yield of gum talha from A. seyal natural stands in the Umfakarin forest, South Kordofan, Sudan. Conducting experiments on the production of gum talha in permanent plot trials in different climatic regions of the Sudan is highly recommended.

Social Impact Assessment of the Natural Forest Protection Program on forest-dependent communities and households in Western China - Case studies in Gansu Province and Chongqing MunicipalityWang, Yi 11 January 2011 (has links) (PDF)
Social Impact Assessment (SIA) is the process of analyzing, monitoring and managing the social effects of planned or implemented development interventions. The primary purpose of SIA is to bring about a sustainable and equitable biophysical and social environment. SIA is a prerequisite in FAO and World Bank aided projects which cover sectors of mining, agriculture, fishery, dams and transportation. In forestry it has the great potential of enhancing sustainable forest management, taking into account rural development objectives and local needs. SIA can be applied before and after the implementation of projects and programs.
In the context of recent policy changes in China, the Natural Forest Protection Program (NFPP) has been implemented in a “top-down” process from 1998 to 2010. A large part of the forests on main river basins in Western regions are being conserved with severe restrictions for commercial use. The social effects of the NFPP are still debatable, indicating a need for conducting a SIA of the NFPP using a systematic conceptual approach.
Objectives of the research are: (1) To understand how and to what extent the NFPP affected the local forest-dependent communities and their households; (2) To identify the local strategies currently used to cope up with the impacts; and (3) To develop the optimal strategies likely supported for a better harmonization between livelihood and the NFPP implementation in different regional contexts.
The empirical research is approached through quantitative and qualitative social research methods for data collection and analysis. For the case studies, four villages with a total number of 175 respondents were selected for field surveys where questionnaires, interviews and group discussions were employed.
The research findings indicate that, the NFPP has significant impacts on the population characteristics, institutional arrangements and infrastructure and public services at the community level and at household level, the income derivation, expenditure, labour time distribution, perceptions on public health/safety and changing values of forests perceived by individuals.
The research reveals that, synthesizing de facto impacts of the NFPP makes potential negative social impacts predictable. The policy-makers and project teams implementing the NFPP should be aware that, the NFPP results in dynamic change processes which include the de facto and potential impacts as well as the influence factors; among these, contribution of strategies derived from local communities and households as the spontaneous reactions to cope with the NFPP impacts should be taken into consideration. Recommendations are given referring to a better implementation of the NFPP and the need for future researches concerning the SIA for sustainable forest management in different regional contexts. / Social Impact Assessment (SIA) ist ein Prozess, der Analyse, Monitoring und Bewältigung der sozialen Effekte geplanter oder durchgeführter Entwicklungsinterventionen umfasst. Das Hauptanliegen von SIA ist, eine nachhaltige und gerechte biophysische und soziale Umwelt zu schaffen. SIA ist für Projekte der FAO und der Weltbank in den Sektoren Bergbau, Landwirtschaft, Fischerei, Talsperren und Transport eine Grundvoraussetzung. Für die Forstwirtschaft ergibt sich daraus das Potenzial, nachhaltige Waldbewirtschaftung zu stärken und dabei die Ziele ländlicher Entwicklung und lokale Erfordernisse zu berücksichtigen. SIA kann vor und nach der Durchführung von Projekten und Programmen angewendet werden.
Im Zusammenhang mit den aktuellen politischen Veränderungen in China wird das Natural Forest Protection Program (NFPP) im Zeitraum von 1998-2010 nach dem top-down-Verfahren durchgeführt. Die sozialen Auswirkungen des NFPP sind noch immer umstritten. Das unterstreicht die Notwendigkeit der SIA unter Anwendung einer systematischen konzeptionellen Herangehensweise. Ein besonders kritischer Faktor dabei ist, dass ein erheblicher Anteil der Wälder in den Wassereinzugsgebieten wichtiger Flussläufe in den westlichen Regionen durch strikte Einschränkungen der kommerziellen Nutzung geschützt wurden.
Die Ziele der Forschung sind: (1) Aufzeigen wie und in welchem Ausmaß das NFPP die örtlichen waldabhängigen Gemeinden und ihre Haushalte beeinflusst hat; (2) Identifizieren lokal entwickelter und angewandter Strategien, um die Auswirkungen des NFPP zu bewältigen; und (3) Entwickeln optimaler Strategien für eine bessere Harmonisierung der Lebensgrundlagen mit der Umsetzung des NFPP in unterschiedlichen regionalen Kontexten.
Die empirische soziale Forschung bedient sich quantitativer und qualitativer Methoden zur Datensammlung und Datenanalyse. Für die Fallstudie wurden vier Dörfer mit insgesamt 175 Befragten ausgewählt. Bei der Primärdatenerhebung kamen Fragebögen, Interviews und Gruppendiskussionen zur Anwendung.
Die Forschungsergebnisse zeigen, dass das NFPP signifikanten Einfluss ausübt auf Größe und Anteil armer Bevölkerung, auf institutionelle Rahmenbedingungen, die Infrastruktur und den öffentlichen Dienstleistungssektor auf Gemeindeebene. Auf Haushaltsebene wurde signifikanter einfluss nachgewiesen für die Generierung von Einkommen, die Ausgaben, die Arbeitszeitverteilung, die Vorstellungen über Gesundheitswesen und Sicherheit als auch auf die Wahrnehmung der sich verändernden Werte des Waldes.
Es wird ersichtlich, dass durch Zusammenführen der de facto-Auswirkungen des NFPP potenzielle negative soziale Einflüsse vorhersagbar werden. Entscheidungsträger und Projektteams sollten sich darüber bewusst werden, dass das NFPP zu dynamischen Veränderungsprozessen führt, welche die de facto- und potentiellen Auswirkungen sowie die Einflussfaktoren betreffen. Dies schließt den Beitrag der lokal entwickelten Strategien ein. Empfehlungen betreffen die bessere Umsetzung des NFPP sowie die Notwendigkeit weiterer Forschung hinsichtlich der SIA im Zusammenhang nachhaltiger Waldbewirtschaftung in verschiedenen regionalen Kontexten.
