Crown age estimation of a monocotyledonous tree species Dracaena cinnabari using logistic regression

Popis výsledku v původním jazyce

Unique woodlands of Dracaena cinnabari (DC) are at risk throughout most of their range (Socotra Island, Yemen) as a result of missing regeneration and overmaturity. Effective conservation measures depend on reliable predictions of future population dynamics, which depend on accurate data on current age structure. However, age determination of Dracaena sp. has long been a scientific challenge, because the common method of tree ring counts cannot be applied to this or to most other monocotyledonous trees.In the present study, the indirect method for crown age estimation proposed by Adolt and Pavlis (Trees 18:43--53, 2004) was further developed using a more appropriate statistical technique and an intuitive model formulation. This new technique is basedon the relationship between the number of branching orders and the number of flowering events that result from a specific growth pattern. We used logistic regression to directly model annual flowering probability, the reciprocal value of
