Assessing landscape perception of urban rocky habitats

Abstract

The urban landscape structure and its changing characteristics have produced various effects on natural and human systems of its own and surroundings [Gilbert OL. The ecology of urban habitats.

By environmental literature conducted recently, it has been evidently comprehended that urban life quality for mankind and others can be improved by serving these systems with green and living elements. This study is to investigate urban rocky habitats that have special natural characteristics and that can be implicated for urban green areas. But these habitats have been considered as nature splits withstanding against the urban pressures by means of the unplanned build-up activities foremost, and road construction, poor quality or neglected remnants. Therefore, this study presents the environmental perception and preferences of urban rocky habitats which are threatening within excessive urbanization and human use of natural areas in the context of the city of Trabzon, Turkey. So, a total of 20 habitats selected from urban and surroundings were surveyed by using a questionnaire and landscape assessment approach. With surveying performed on 204 participants, visual preferences, landscape attributes and proposed management options for urban nature conservation were determined. The χ 2 -test results revealed clearly that the demographic and expertise status of the participants were correlated with the preferences for types of rocky habitat scene and management options. The scenes with natural elements and less human disturbance obtained higher scores on visual preferences than any of the urban rocky scenes lacking these characteristics. Also, in the quantitative phase, factor analysis based on principal component structure revealed the ‘ visual and spatial effects’, the ‘ usage and arrangement’, the ‘ naturalness and ecological value’, and the ‘ functionality’ components of the scenes. Consequently, some implications for the effective and efficient planning and development of urban nature conservation by assisting the better understanding of the various patterns of landscape preference, choice and satisfaction in habitats under the present study were suggested.
