Biometric-Based Net Primary Production (NPP) and the Effects of a Masting Event on Production Allocation in a Secondary Lucidophyllous Forest in Central Japan
Lucidophyllous (evergreen broad-leaved) forests are the dominant forests in human-dominated subtropical/warm-temperate regions in East Asia. Biometric-based estimates of net primary production (NPP) were conducted in a secondary lucidophyllous forest on Mt. Kinka (35°26′ N, 136°47′ E) near the north...

| description | Lucidophyllous (evergreen broad-leaved) forests are the dominant forests in human-dominated subtropical/warm-temperate regions in East Asia. Biometric-based estimates of net primary production (NPP) were conducted in a secondary lucidophyllous forest on Mt. Kinka (35°26′ N, 136°47′ E) near the northern limit of their distribution in central Japan for three years, including the masting event. The forest stand mainly consists of <i>Castanopsis cuspidata</i> (Thunb.) Schottky and <i>Cleyera japonica</i> Thunb. in the canopy and subtree layers, respectively. In 2018, the total NPP of the masting year was 14.53 ± 2.03 ton ha<sup>−1</sup> yr<sup>−1</sup>, including woody NPP (above: 2.63 ± 0.35 ton ha<sup>−1</sup> yr<sup>−1</sup>; below: 0.57 ± 0.08 ton ha<sup>−1</sup> yr<sup>−1</sup>), foliage NPP (4.07 ± 0.23 ton ha<sup>−1</sup> yr<sup>−1</sup>), reproductive NPP (4.81 ± 0.77 ton ha<sup>−1</sup> yr<sup>−1</sup>), and fine root production (<i>P<sub>fr</sub></i>) (2.46 ± 1.84 ton ha<sup>−1</sup> yr<sup>−1</sup>). <i>P<sub>fr</sub></i> and belowground production comprised 16.9% and 20.9%, respectively, of the total NPP. The nut production of <i>C. cuspidata</i> in 2018 (4.31 ± 0.75 ton ha<sup>−1</sup> yr<sup>−1</sup>) was significantly higher than that in 2017 (0.77 ± 0.13 ton ha<sup>−1</sup> yr<sup>−1</sup>) and 2019 (0.23 ± 0.06 ton ha<sup>−1</sup> yr<sup>−1</sup>). No significant change was observed for the three years of foliage NPP and total NPP without <i>P<sub>fr</sub></i>. However, the woody NPP in 2018 (3.20 ± 0.43) was lower than in 2017 (5.37 ± 0.33 ton ha<sup>−1</sup> yr<sup>−1</sup>) and 2019 (4.71 ± 0.38 ton ha<sup>−1</sup> yr<sup>−1</sup>). This suggests that nut production in the masting years compensated by decreasing woody production in the <i>Castanopsis</i> forest. |
