The influence of plant diversity on people's perception and aesthetic appreciation of grassland vegetation AbstractThe conservation of biodiversity critically depends on the value that humans attach to it. Apart from an ecological and economic value, an aesthetic value has often been assigned to biodiversity. However, it is not known whether lay people appreciate the diversity of species and not just certain individual species or nature as a whole. We studied in a series of experiments and field studies people's perception and appreciation of species diversity. We presented meadow-like arrays of different species richness and evenness but random species composition to lay people and asked them to estimate plant species richness and rank the arrays by attractiveness. The experiments were complemented by two larger-scale field studies using natural meadows. Both in the experiments and the field studies the mean perception of species richness by people increased with true species richness, but was slightly overestimated at low and increasingly underestimated at high diversity levels. Lay people's aesthetic appreciation of both the experimental grassland arrays and the natural meadows increased with true species richness.Communities consisting of the same number of species were perceived to be more species-rich and were appreciated more when their evenness was high. Our results demonstrate that plant diversity in itself is attractive to humans. The current reduction of the diversity of grasslands due to intensification of management may thus reduce the attractiveness of regions where grasslands are a dominant feature of the landscape. This could have negative consequences for tourism and may add an economic argument for the conservation of biodiversity in grasslands.Lindemann-Matthies, P., Junge, X., Matthies, D. 2010.

This paper presents the results of interviews and a questionnaire study on public knowledge of the concept of biodiversity and of plant species richness in Switzerland.

Maintenance of the agricultural landscape, preservation of biodiversity and landscape aesthetics are part of a multifunctional agriculture. However, little is known about the influence of single agricultural landscape elements in different seasonal stages on landscape aesthetics. In a Swisswide photo survey, the aesthetic preferences of Swiss residents for typical agricultural landscape elements in the Swiss lowlands were investigated. Photographs of seven ecological compensation areas (ECAs) and seven other elements (crops, high-intensity meadows and pastures) were selected. Each element was presented in four to six different seasonal stages, each on single paper-based questionnaire pages to allow a random selection of elements and seasonal stages. In addition, each element was replicated in each seasonal stage. Four randomly selected elements were sent to each study participant for aesthetic valuation (preference rating scores). Overall, ECAs received higher preference ratings than crops or high-intensity grassland. Most preferred were ECAs with a vertical structure, i.e. trees and bushes, and species-rich elements. In addition, the seasonal stage of a landscape element strongly influenced preference ratings. Flowering stages were clearly liked most. Moreover, perceived diversity and naturalness of an element had a strong positive effect on its rating. The results indicate that ECAs, besides their ecological function, are powerful elements to enhance the public's preference for agricultural landscapes. Moreover, the results might be useful for the development and adaptation of quantitative methods to capture the aesthetic value of agricultural regions and might provide a basis for political decisions concerning direct payments for aesthetic services of agriculture. AbstractThe maintenance of cultivated landscapes, the conservation of biodiversity and landscape aesthetics are part of a multifunctional agriculture. However, little is known about the influence of single agricultural landscape elements in different seasonal stages on landscape aesthetics. In a Swiss-wide photo survey we investigated the aesthetic preferences of Swiss residents for different agricultural landscape elements that are typical in the Swiss lowlands.Photographs of seven crops and seven ecological compensation areas (ECAs) were selected.Each element was presented in four to six different seasonal stages on single paper-based questionnaire pages and, in addition, replicated four times. A random selection of four elements was sent to each study participant who had to rank the four in decreasing order of aesthetic value (preference rating scores). Overall, ECAs received higher preference ratings than crops. Most preferred were high-stem fruit trees, hedgerows, and low-intensity pastures, i.e. ECAs with a vertical structure. Study participants characterised ECAs as varied, speciesrich and beautiful. In addition, the seasonal stage of a landscape element strongly influenced preference ratings. Flowering stages of both ECAs and crop...
