Seedlings were sourced from local nurseries, with the coordinates of seed source used to determine the climate of origin for the source populations (Table 1, Supporting information S1, Supporting information S2). Nursery guidelines recommend a seed collecting strategy of collecting from multiple individuals (Commander, 2021), however seed donations were also accepted by the nurseries, and the total number of mother trees for the seedlings used in our common garden was unknown. Seedlings of upland origin were sourced from the Atherton tablelands, and seedlings of lowland origin were largely sourced around Cape Tribulation and Diwan, close both geographically and climatically to the DRO common garden site (Supporting information S1).
