| Species | 4 | 3.670 | <0.008 |
| Bark treatment | 1 | 1.594 | 0.210 |

Percentage mass loss (logit transformed) was modelled over 24 months as function of number of days (2nd order polynomial), bark treatment, species and all two-way interactions (for the full model and summary see Table S3 in supplementary material). There were five species: Kleinhovia hospita, Tectona grandis, Cunninghamia lanceolata, Dipterocarpus turbinatus, Toona ciliata, and bark treatment had two levels: branches with bark and branches without bark. DF denotes degree of freedom. Denominator DF = 98.
