Visitor demographics, perceptions and their relationships are investigated to determine the problems and issues for outdoor recreation, which has been a neglected part of the Turkish national park system, using the case of Termessos National Park, located in the south of Turkey. The park is attractive for both its historical and natural resources. Five demographic characteristics (gender, age, nationality, education level and income level) were used to test perceptions of the park resources, preference for number of groups and perception of crowding. The data was collected via a questionnaire survey administered on-site. Chi-square tests demonstrated that perceptions are significantly influenced by the nationality of respondents. Archaeological ruins were perceived as the most popular park resource, and were more appreciated by the older age groups, French visitors and those with higher education. Although the park was not perceived to be crowded, at least 25% of all age groups and 30% of all nationalities preferred not to encounter any other groups, whereas a significant majority of Turkish visitors (over 95%) did not mind having one or two groups present during their visit. Visitors with higher education and income levels preferred to encounter fewer groups. At least 60% of the visitors were comfortable with the actual condition of the park. The trails, signage and brochures were considered major problems. As an integrated part of the ruins, redesign of trails was perceived as necessary. Signage was perceived to be the second most important problem, which is also related to trails and orientation, whereas brochures were suggested as supplementary materials.

Abstract In this study, the extent and distribution of visual and morphological characteristics and diversity based on seven origin sites for 37 chaste tree (Vitex agnus‐castus) genotypes selected from the east coast of Antalya Province (southern Anatolia, Turkey) were determined. Plant size, growth habit, and flower colour were used as visual characteristics. Morphological characteristics included primary and secondary panicle lengths and flower numbers, petiole length, mid‐leaflet length and width, and flowering branch diameter. Genotypes differed significantly in both overall and within origin sites in terms of frequency for visual characteristics. Similar large diversities were recorded between and within origin sites for morphological characteristics. Pearsons coefficients revealed that there were several significant and positive correlations between morphological characteristics of V. agnus‐castus genotypes. Cluster and principal component analyses based on means of genotypes for morphological characteristics confirmed large variations between V. agnus‐castus genotypes.
