Sandıras Dağı'ndaki (Muğla) Four new tree-ring chronologies from old black pine forests of Sandıras Mountain (Mugla, Turkey)Abstract: Sandıras Mountain is located in southwest of Gölgeli Mountain, which lies parallel to border of Aegean and Mediterranean Regions, in Southwestern Anatolia. This mountainous area is one of the natural distribution areas of black pine (Pinus nigra Arn.) and has the oldest black pine communities in Turkey. Monumental black pine stands and the large number of individual monumental trees can be observed between the 1200 and 2000 m elevations of the mountain (especially north slope of the mountain). In this paper, we present preliminary results of a dendrochronological research on old black pine trees of Sandıras Mountain. Four new tree-ring chronologies were built from upper and lower elevations of south and north slopes of the mountain. The shortest and the longest chronologies were 241 and 820 years-long (obtained from upper elevation of the north slope), respectively. In this research, we record the most sensitive black pine trees (mean sensitivity value is 0.27) of Turkey from the north slope of Sandıras Mountain.

Influence of Climate on Radial Growth of Black Pine on the Mountain Regions of Southwestern Turkey

“…We used four black pine tree-ring chronologies built by Doğan and Köse [44] which represent upper and lower distribution limits in south and north slopes of Sandıras Mountain. Samples were taken from Eskere, Çiçekli (Denizli) for north slope of the mountain, and Köyceğiz, Ağla (Muğla) for south slope (Figure 8).…”

“…Samples were taken from Eskere, Çiçekli (Denizli) for north slope of the mountain, and Köyceğiz, Ağla (Muğla) for south slope (Figure 8). Following steps were performed to build the chronologies by Doğan and Köse [44]: At least two increment cores per tree (from living trees) at breast height (1.30 m) were collected. Cores were glued onto grooved boards and sanded until annual rings were clearly visible.…”

“…The mean sensitivity, which is a metric representing the year-to-year variation in ring width [2], was calculated for each chronology and compared (Table 1). Summary site information and statistics of the chronologies were given in Table 1 [44]. Monthly total precipitation and mean temperature records of Muğla Meteorological Station (1936–2006) were used in the analysis.…”
