Functional traits of the tallest tropical tree species in Borneo, 2022

Samples were collected from 38 individual trees of five Dipterocarp species throughout May-July 2022. To measure trait values 1-2m length branches were extracted from each sample location in the tree crowns (upper crown, and when crown depth allowed, also mid-crown and lower-crown). Vertical height and horizontal distance from the main stem were recorded for each excised branch to enable hydraulic path length to be calculated. In addition, wood cores were extracted with increment borers at breast height (1.3m, or just above any buttresses). Immediately after sampling material was sealed in moist bags and transported to laboratories at the Sabah Forest Research Centre (10-30 minutes' walk), where functional traits were measured. The traits measured included leaf and wood structural traits, leaf and wood hydraulic traits and wood anatomy traits. The full list of traits measures and procedures used to measure the traits are laid out in the supporting information. All data were entered into a excel spreadsheet and saved as a .csv file.
