  • This dataset details the allometry and leaf trait measurements in three common gardens of fifteen juvenile tree species from the Colombian Andes planted along a thermosequence (14, 22 and 26 deg C) in the Antioquia region of Colombia. Allometric data includes tree diameter at the base, total tree height and height to the first branch, crown diameters, health status, survival and percentage of herbivory attacks over ten measuring campaigns from February 2019 until January 2022. Trait data includes leaf area, thickness, dry weight, leaf mass per area total number of branches and leaves per tree. Regarding the common garden plantations the trees were planted in the ground between November 2019 and January 2019 with planting height ranging between 50 and 100 cm (species dependent).

  • This dataset contains information on how variations on temperature and photoperiod affects poplar seedling growth in Eco chambers. Plants were propagated on sterile media (1/2MS, 0.7% Agar, 1mg/L IAA) by cutting the shoot tip and 3-4 leaves and placing them in a weck jar on new medium. Once the explants rooted after incubation at 200 mmol light, 21C day/18C night, long day conditions (16:8) and ambient humidity, they were transplanted onto soil (6:2:1 Peat-free: sand-vermiculite, fertilizer: 4 g/L Osmocote exact standard 15-9-12) and grown first under protective covers and then open in 24C, long day conditions (LD), 65% humidity, 350mmol light (experiments R1-3) or transferred into the Eco chamber (temperature as indicated in experiment, 80-98% humidity, 350mmol LED light, long day conditions). After 3-4 weeks, plants of R1-R3 were transferred in the conditions described in the experiment (R1: 24C SD vs 15C LD; R2: 15C SD vs 15C LD; R3: 15C LD vs 24C LD) and grown for a month before moving them into 5C low light conditions which resulted in senescence and leaf drop. Eco chamber plants were grown in the Eco chamber for about four weeks and after not showing senescence, harvested directly after the experiment without cold incubation. All plants were measured in height and diameter (6cm above soil), leaf number and area regularly and gas exchanged was measured with a TARGAS-1 instrument (Hansatech) at 500mmol light intensity. After the experiment, cross-sections were taken and embedded in resin for further microscopic analysis (data not ready and not included).

  • Phenotypes (growth and phenology) for Scots pine trees in a long-term common garden trial planted in three sites in Scotland, surveyed annually from 2013 to 2020. Full details about this dataset can be found at https://doi.org/10.5285/1c9367fb-ea87-47a1-8257-d9fed54215e7

  • This dataset contains daily temperature and temperature variance measurements recorded at three nurseries in Scotland between 2007 and 2012. Each nursery contained Scots pine trees grown using seed collected from 21 native Caledonian pinewood provenances, with 8 seedlings from each of 10 families per provenance (total 1680 trees per nursery) included. This dataset was created as part of a multi-site long term garden experimental trial investigating the effect of nursery environment on Scots pine growth and development, and is part of the newLEAF and PROTREE projects.

  • This dataset consists of survival and heights of trees planted for forest restoration in South and Southeast Asia and the associated analytical code. The data consists of tree censuses collated from published studies, grey literature and data provided by co-authors, up to/including May 2021. Data are collated from 176 sites in areas where disturbance or clearance of the natural forest had occurred and where trees were then planted and monitored over time. The analyses included here model height growth, extract annual size-standardised growth rates and test the effects of biophysical and climatic conditions and planting regimes on survival and growth. This dataset was created to represent the current state of knowledge on forest restoration outcomes in South and Southeast Asia. This is the full dataset for the survival and height analysis.
