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).
