Summary of models selected to explain basal area increment (BAI) recovery of Pinus sylvestris from four study sites in eastern Spain after a 2001 climatic extreme cold event
| Site | Defoliation | Competition | Sapwood area | Soil depth | ΔAIC | Wi |
|---|---|---|---|---|---|---|
| Barranco de la Hoya-North | – | – | – | – | 1·38 | 0·35 |
| Barranco de la Hoya-South | −7·45* | – | – | – | 0·23 | 0·33 |
| Peñacerradilla-North | – | – | – | – | 1·73 | 0·30 |
| Peñacerradilla-South | −8·08* | – | – | 0·82 | 2·12 | 0·41 |
Generalized least square (GLS) models were used to explain BAI recovery in each site using as explanatory variables: defoliation level, competition index, sapwood area and soil depth.
The asterisks (*) indicate that the variable has a significant (P < 0·05) influence on BAI recovery.
