Allometric management models for Greek fir (Abies cephalonica Loudon) at Parnassos Mt., Greece

The Greek fir (Abies cephalonica Loudon), is a significant species in Greece of high ecological and economic value. However, despite its high importance, a notable lack of allometric models regarding its basic dendrometric attributes at tree level can be observed. The current study aimed to fill this knowledge gap. Based on a sample of 2873 well-documented fir trees from 47 sample plots in Parnassos Mt., in central Greece, nonlinear mixed-effects allometric models for the prediction of total hei
