This dataset contains information about temperature response curves of ACi (i.e., CO2 response curves of net photosynthesis) that were collected on Colombian Andean forests tree species that were planted in three, common-garden tree plantations along a 2000m altitudinal gradient. Specifically, individuals of cold- and warm-affiliated species were planted under common soil and water conditions, exposing them to the hot and cold extremes of their thermal niches, respectively. This work was supported by the UK Natural Environment Research Council (NE/R001928/1) Full details about this dataset can be found at https://doi.org/10.5285/cc4c656f-4e4d-4f26-af23-69b4f007e43f
