Abstract

This paper describes a study on the vegetation and floristics of the territory of Beit Jibrin in Palestine, in areas such as Forest the Snabreh (Qasa), Khallet Mahmoud and Khallet AL-Taweel, among others. In view of the lack of studies on the phytosociology and communities of plants in the south-west of Palestine, as this region represents a unique diversity of plants, and the addition of these plants to Mediterranean Basin region plants, we conducted this study to identify and describe the plants of this region. Beit Jibrin is an ancient Canaanite Palestinian city that belongs to inframediterranean and thermomediterranean thermotypes, as well as arid, semi-arid and dry ombrotypes. This area is very important floristically, with a high rate of endemism: of the 290 species documented, 37 of them (12.75%) were endemic to the region. Vegetation was sampled on twelve representative plots (releves) and analyzed using the Braun-Blanquet phytosociological analysis method. Two communities of forest maquis, macchie and steppe vegetation were found. Forest vegetation were represented by the Cupresso sempervirentis–Pinetum halepensis ass. nova. association, in the class of Quercetea ilicis Br.-Bl. ex. A. and O. Bolòs 1950, the order of Pinetalia halepensis, Biondi et al. (2014), and a new alliance: Cupresso sempervirentis–Pinus halepensis; forests maquis vegetation as the association of Pistacio lentisci—Quercetum calliprini ass. nova., with the suggested new class of Quercetea calliprini or palaestini in addition to Quercetea ilicis Br.-Bl. ex. A. and O. Bolòs 1950 and the order of Quercetalia calliprini (Zohary 1960), with an alliance of Quercion calliprini (Zohary 1960). These were adapted in arid, semi-arid, dry and sub-humid ombrotypes, as well as infra- and thermotropical to mesomediterranean thermotypes, with many different types of soils, such as limestone, brown ruinsenas, terra rossa and others.

Highlights

  • Palestine is a hotspot for biodiversity and flora, and is considered one of the most biodiverse countries in West Asia and the Mediterranean coast

  • The purpose of this paper is to study the phytosociology of this paper is to study the phytosociology and plant taxa species of the Beit Jibrin region and taxa species of the as Jibrin in the southwest of region, Palestine as well as of in theplant southwest of Palestine well as ofregion the Mediterranean

  • We used a phytosociological nomenclature code in the dedescription of the new syntaxons in the study [36,37,38] and Euclidean distances as well as principal component analysis to evade any lack of data on whole-plant analysis; the XLSTAT Statistical Software for Excel program was used in the analysis process

Summary

Introduction

Palestine is a hotspot for biodiversity and flora, and is considered one of the most biodiverse countries in West Asia and the Mediterranean coast. Palestinian coastal waters and mountain highlands possess a large level of biological diversity, in addition to many endemic and native species. Geographical and biological diversity is very important, consisting of landscapes and ecosystems that include areas of mountainous heights, plains, valleys, cliffs, sand dunes, steppes and forests. This prompted us to study the plant species of an important region located to the southwest of Palestine, west of the Jordan River and the Dead Sea, with the varieties of wild and forest plants it represents, as it is fertile and rich in forests of various plants.
