Annual mortality and growth index for 17 tree species across entire size classes in the Ogawa Forest Reserve, an old-growth deciduous forest, central Japan

We estimated demographic parameters across entire size classes for 17 tree
species (Betula, Carpinus, Fagus, Quercus, Castanea, Acer, Cerasus, Swida,
Kalopanax, and Styrax) using a dataset over 18 years obtained from the
Ogawa Forest Reserve, an old-growth deciduous forest located in the
southern part of the Abukuma Mountains, Ibaraki Prefecture, central Japan
(36° 56', 140° 35', 610 m in elevation) 1). Size classes were
represented by 12 categories defined based on age, height, and diameter at
breast height (DBH): new seedling (age < 1), aged seedling (age ≥ 1
and height < 30 cm), sapling (height 30 cm to 2 m), juvenile
(height ≥ 2 m and DBH < 5 cm), D10 (DBH 5–15 cm, D10 was denoted by
the midpoint of this range; later classes were similarly defined), D20,
D30, D40, D50, D60, D70, and D80 (including trees with DBH ≥ 85 cm). We
derived the annual mortality and growth index (i.e., the probability of a
living tree transitioning to the next size class) for each species and
size class using estimates of transition probabilities between size
classes (i.e., stasis, progression and retrogression)2). The stem
densities of these 17 species in each size class are also presented3).
