The Use of Native Halophytes in Landscape Design in The Central Anatolia, Turkey

Abstract

In this study, the usability of some herbaceous halophytes grown naturally in salt marshes that dry most of the year in Central Anatolia Region were investigated in landscape design. Within the scope of the research, in the years of 2016 and 2017, seasonal field studies were carried out in saline habitats in the vicinity of Konya, Ankara, Aksaray and Nevşehir, and taken photographs and herbarium samples of halophytic plant species. The general botanical and ecological characteristics of the selected species are given and the values used in landscape design have been determined considering the aesthetic and functional properties. As a result of the field studies carried out during the vegetation periods, 59 halophytic plant species, belonging to 38 genera and 19 families that could be used in landscape design were identified. The most representative family was the Asteraceae with 11 species, followed by Plumbaginaceae (9 species) and Chenopodiaceae (8 species). The genus Limonium from Plumbaginaceae family is well represented with 8 species for landscape use. The endemism rate of halophytes used in landscape design is 42% (25 species) in the research area. The most common uses in landscape design are determined in roof gardens by 49 species, followed in ground conservation and erosion prevention by 31 species. Since these halophytic species, which are mostly succulent and endemic, are well adapted into both wet and dry areas. Their use in landscape design is of great importance for restoration of arid and barren land, which may increase as a result of global climate change, conservation of biodiversity as well as sustainable agricultural practices.
