Four situations occur, depending of the size of the damaged tree (above or below “normal” nursery size) and depending on the need to remove the tree. The model applies only if the damaged tree is above “normal” nursery size.
| Size of damaged tree | Tree removal | No tree removal |
|---|---|---|
| Above “normal” nursery size | 1 | 2 |
| Below “normal” nursery size | 3 | 4 |
