Age structure and growth of Dracaena cinnabari populations on Socotra

Popis výsledku v původním jazyce

Unique woodlands of Dracaena cinnabari on Socotra Island -- last preserved relics of the Mio-Pliocene xerophile-sclerophyllous southern Tethys Flora -- were examined in detail, especially with regard to their age structure. Detailed statistical analysesof the set of 50 trees at 4 localities were performed in order to define a model reflecting relationships between specific growth habit and actual age. The problematic nature of determining the age of an individual tree or specific populations of Dracaena cinnabari (DC) is illustrated on three models relating to orders of branching, frequency of fruiting, etc. which give conditions to calculate actual tree age. Based on statistical analyses as well as direct field observations, DC populations on Socotrado not regenerate to a greater extent and their age structure generally indicates overmaturity. The unique Firmihin DC woodland will reach the stage of intensive disintegration within 30-77 years with 95% probability. According to the an
