Weak local adaptation to drought in seedlings of a widespread conifer

Tree seedlings from populations native to drier regions are often assumed to be more drought tolerant than those from wetter provenances. However, intraspecific variation in drought tolerance has not been well characterized despite being critical for developing climate change mitigation and adaptation strategies, and for predicting the effects of drought on forests.
We used a large-scale common-garden drought-to-death experiment to assess range-wide variation in drought tolerance measured by decline of photosynthetic efficiency, growth, and plastic responses to extreme summer drought in seedlings of 73 natural populations of the two main varieties of Douglas-fir (Pseudotsuga menziesii var. menziesii and var. glauca).
Local adaptation to drought was weak in var. glauca and nearly absent in menziesii. Var. glauca showed higher tolerance to drought but slower growth than var. menziesii. Clinal variation in drought tolerance and growth species-wide was mainly associated with temperature rat..., , , # Weak local adaptation to drought in seedlings of a widespread conifer

This dataset contains the raw phenotypic data of individual plants from the drought experiment conducted for the study. The data includes height growth, visual damage, and Fv/Fm measurements collected at five different time points. For the manuscript by Candido-Ribeiro and Aitken (2024), only the 73 provenances from \"natural\" origin and varieties *glauca* and *menziesii* were used. Provenances from \"orchard\" origin and the species *Pseudotsuga* *macrocarpa* (in the variety column as \"*macrocarpa*\") were excluded from the analysis.

**Description of the dataset (columns):**

* box = the boxes used in the experiment with 90 active plants (\"subplot\" column). In total, there were 16 boxes (8 for \"Dry\" treatment and the other 8 for \"Wet treatment\").
* block = Each block contains 2 boxes (1 for \"Dry\" treatment and 1 for \"Wet\" treatment). There were 8 blocks in total.
* provenance = provenance (population) number....
