Description

<p>Tree-ring analysis was performed for eight Cinnamomum camphora trees dead and fell after a typhoon storm surge at Ozato Matsubara coastal forest, Tokushima Prefecture, western Japan, to analyze the long-term growth process of broad-leaved trees planted in coastal forests. Tree-ring width in all four directions of the compass was determined on disk samples at 0.3 m ground height. Tree rings of 31 to 37 years were counted, and the mean tree ring width of each individual ranged from 5.5 ± 2.6 mm to 12.0 ± 4.6 mm with an overall mean of 9.4 ± 4.1 mm (±sd). The diameter at breast height was determined to reach 47.3 ± 9.6 cm within 30 years of the establishment, by using the ratio of diameters at 0.3 m and breast height. The sparse planting interval of 5.2 m to the nearest neighbor was causally associated with the quick thickening growth of the C. camphora trees.</p>
