title: Data from: Survival and growth of three boreal conifer species transplanted to warm sites: Implications for responses to global warming and extreme climatic events

description: Understanding the responses of boreal conifers to climate change is
 essential for future mitigation and adaptation. In this study, 3-year-old
 seedlings of three Japanese boreal conifers, including Sakhalin fir, Yezo
 spruce, and Sakhalin spruce, naturally found in Hokkaido, Japan, were
 transplanted in spring 2016 to a cool control and two warm (air-dried
 interior and humid coastal) sites. We investigated survival, height, and
 ecophysiological traits based on three parameters: stable carbon isotope
 discrimination (δ13C), specific leaf area, and leaf mass-specific nitrogen
 concentration ( N) of seedlings during experiments. The survival rates of
 two spruce species were gradually significantly lower in warm sites, while
 that of Sakhalin fir did not significantly differ among sites. The
 relative growth rate (RGR) of two spruce species was significantly lower
 in the warm-interior site than in both cool control and warm-coastal sites
 in 2018, although in 2017, the RGR of two spruce species was lower in the
 warm sites than in the cool control site. The less negative δ13C value in
 2018 revealed that a vapor pressure deficit might decrease the spruces’
 RGR via stoma closure in the warm-interior site. We found that Sakhalin
 fir would be less sensitive to climate change than the two spruce species.
description: Three boreal conifers (Sakhalin fir, Sakhalin spruce, and Yezo
 spruce) are distributed in natural forests in Hokkaido, Japan. Seeds of
 three conifers collected from the University of Tokyo Hokkaido Forest
 (UTHF), Furano, central Hokkaido, Japan.  Saplings of three boreal
 conifers were grown in the nursery in the UTHF. In May 2016, 144 saplings
 (~12 cm in height) of each species were transplanted at the three sites:
 CBA, CCB, and FRN. 432 saplings (three species × three sites × 48
 individuals) were planted.

Height and diameter were measured in autumn 2016, 2017, and 2018. SLA, N, and δ13C were measured using current-year shoots from saplings of three boreal conifers: Sakhalin fir, Sakhalin spruce, and Yezo spruce.  SLA was calculated as the ratio of leaf area to dry mass after the needles were dried in an oven. N and δ13C were measured with an elemental analyzer coupled to a stable isotope ratio mass spectrometer.  RGR was calculated from biomass estimated from individual size.
