Vascular plants of Honaz (Denizli) Forest Planning Unit

Abstract

This study was conducted to determine the vascular plants of Honaz Forest Planning Unit between 2009-2010. The study area is located between the Mediterranean and Iran-Turanian phytogeographic regions in Denizli province. Because of this study, 276 vascular plant taxa belonging to 56 families were determined. Three of the identified plant taxa belong to Pteridophyta section and 273 belong to Magnoliophyta section. Seven (2.5%) of the plant taxa in the Magnoliophyta section belong to the Pinidae subclass and 266 are within the Magnoliidae subclass. Number of endemic taxa identified was 39 and the endemism rate of the study area was calculated as 14.1%. The distribution of the threat categories is as follows: one taxa in Endangered (EN), 3 taxa in Vulnerable (VU), 11 taxa in Near Threatened (NT), 24 taxa in Least Concern (LC). The richest family was Asteraceae (with 41 taxa), followed by Lamiaceae (with 25 taxa), Brassicaceae (with 21 taxa), and Fabaceae (with 21 taxa). The phytogeographic regions of 125 taxa represented in the study area are as follows: East Mediterranean 17% (47 taxa), Mediterranean 13% (36 taxa), Irano-Turanian 3.9% (11 taxa), Euro-Siberian 2.2% (6 taxa), East Mediterranean (mount) 0.4% (1 taxon), Omni-Mediterranean 0.4% (1 taxon), and multiregional or of unknown phytogeographic origin 55% (153 taxa). Raunkiaer’s life forms showed that Hemicryptophytes with 138 taxa, Therophytes with 51 taxa and Phanerophytes with 41 taxa were the most frequent life forms.
