This study has revealed that climate change will significantly affect adversely the distribution of some of the most important medicinal, ecological and economically important tree species of the Valley. This change will not only modify the landscape but the whole socio-ecological system of the area. Plants like Abies pindrow, Pinus wallichiana, Cedrus deodara and Pinus roxburghii will be directly affected by the a2a climate change scenario for the year 2080.
This study also predicts the trend in altitudinal movement of species as a consequence of climate change; as the northern parts of the Valley provide high altitudes of significantly colder environment than the southern parts. The ethno-cultural study revealed that the people of the area have a well established ethnomedicinal culture in place and some plants could be at high risk of extinction from the unsustainable practices of plant collection. The core plants of the ethno-culture were Berberis lyceum in five calculated indices: Salience Index (SI), Relative Importance Index (RII), Cultural Value Index (CVI), Cultural Importance Index (CII), and Ali’s Conservation Priority Index (CPI); Skimmia laureola ranked second in the SI, fifth in the RII, seventh in CVI, third in CII, but ninth in CPI, and Mentha longifolia ranked third in the SI, and RII.
Detailed biodiversity analysis has revealed that different parts of the Valley have different biodiversity index values. Some locations like location 1(Landakay, Kota, Aboha and Barikot), Location 4 (Aqba and Saidu Sharif) and Location 7(Fateh Pur), have high rankings in various biodiversity indices and further GIS analysis has identified present and future biodiversity hotspots. Digital Elevation Models (DEMs), extrapolated in the GIS, have revealed species preferences for certain altitudinal zones and the Ordination Analyses confirmed plant-plant and plant-location interaction responses in the area. It is concluded that a real threat to the biodiversity, forests and MAPs exists and only careful policy planning can rescue the area from permanent biodiversity loss in the Swat district.
The Swat district has very varied vegetation structure due to the great geophysical variation. There is a great potential for the Valley to act as an economic hub for Pakistan in the Medicinal and Aromatic Plants (MAPs) industry. However, the forest ecosystem services of the Valley are under continuous threat from the direct and indirect anthropogenic stresses.

Zusammenfassung der Kapitel (Chapter Summaries)
Chapter 1 General Introduction: This chapter introduces the concept of biodiversity and its importance, highlighting the rapid depletion of forest resources globally and in Pakistan. It emphasizes the economic value of forest ecosystem services, including timber and non-timber forest products (NTFPs), particularly medicinal and aromatic plants (MAPs). The chapter profiles the Swat Valley, detailing its history, topography, climate, and socio-economic structure. It establishes the study's justification, outlining objectives and the thesis's overall structure.
Chapter 2 GIS, Climate Change and Species Distribution: This chapter reviews the literature on GIS applications in ecological research, focusing on habitat mapping, species distribution modelling, and the impacts of climate change. It covers various modelling techniques and their applications in Pakistan, emphasizing the need for integrating GIS with field data for accurate predictions and effective conservation planning.
Chapter 3 Medicinal and Aromatic Plants (A Literature Review): This chapter provides a comprehensive review of the literature on medicinal and aromatic plants (MAPs), globally and in Pakistan. It discusses current global trends in the MAP trade, the plant species involved, the threats to their conservation, and various conservation measures. The chapter also reviews existing ethnobotanical research in Pakistan, focusing on studies from the Swat Valley and highlighting the region's rich ethno-medicinal knowledge and the threats to its sustainability.
Chapter 4 Climate Change and Species Modelling: This chapter details the methods and results of species distribution modelling using Maxent, a maximum entropy approach. It describes the data used (species presence records and bioclimatic variables), the modelling process, and presents the results as GIS maps predicting current and future (2080) distributions of selected tree species. The chapter discusses the implications of these predictions for conservation and the local economy.
Chapter 5 Ethnobotany of the Swat Valley: This chapter presents the ethnobotanical study of the Swat Valley, investigating the cultural significance of medicinal plant use. It uses questionnaires and freelisting interviews to gather data on plant uses, knowledge sources, and community perceptions regarding conservation. Several indices (Salience Index, Relative Importance Index, Cultural Value Index, Cultural Importance Index, and a newly developed Conservation Priority Index) are calculated and analyzed to quantify the cultural importance of plant species and to identify those at high risk of extinction.
Chapter 6 Vegetation Analysis of the District Swat: This chapter focuses on the biodiversity analysis of different locations within the Swat Valley. It utilizes quadrat sampling, hierarchical clustering, and the calculation of various biodiversity indices to compare different sites. The chapter identifies biodiversity hotspots, discusses factors affecting species richness, and assesses the conservation status of different plant communities, linking findings to anthropogenic disturbances and ecological interactions.
Chapter 7 GIS Mapping of the Plant Communities: This chapter presents GIS-based mapping of plant communities in the Swat Valley. It uses digital elevation models (DEMs) to create altitudinal maps of tree species and employs ordination techniques (DCA and CCA) to analyze species-environment relationships. The chapter integrates the results of the Maxent modelling and biodiversity analysis to identify current and future biodiversity hotspots and to assess the extinction risk to plant species under future climate change scenarios.
