Holocene vegetation history of the southern Levant based on a pollen record from Lake Kinneret (Sea of Galilee), Israel

摘要

Lake Kinneret, also known as the Sea of Galilee and Lake Tiberias, is located in the northeast of Israel. At a lake level of 211 m b.s.l. (below mean sea level), the central basin is 43 m deep. The maximum length of the lake is 21 km (N-S) and its maximum width is 12 km (W-E). Lake Kinneret's surface area is 166 km(2). A new 17.8 m long sedimentary core was drilled in 2010. Here, we present the entire palynological record from it, which covers the last 9,000 years. Special emphasis is given to the natural and human-influenced vegetation history of Galilee in comparison to that of the more southerly Dead Sea region. Significant signs of human impact are the first Olea (olive) increase during the beginning of the Chalcolithic period between 7,000 and 6,500 years ago, as well as the prominent Olea phase during the Hellenistic/Roman/Byzantine period between 2,300 and 1,500 years ago. Mediterranean macchia and bathas scrub vegetation, as known in the area today, has developed in the southern Levant under human impact since the last ca. 1,500 years.
