From: Alternative approaches to assessing the natural regeneration of Scots pine in a Mediterranean forest
Method | Edaphic and topographic variables | Competition and stand variables |
|---|---|---|
GLMM | Na (−); P (−) | Number of stumps (+) |
GLMM after PCA | n.s. | Component related to the number of stumps (+) |
NMDS | n.s. | n.s. |
CHAID | Na (−) | Number of remaining trees (non-linear) |
Random forest and conditional inference tree | Na (−) | Number of stumps (+) |
