    Dragon's blood tree -- threatened by overmaturity, not by extinction: Dynamics of a Dracaena cinnabari woodland in the mountains of Soqotra

  • Original language description

    Age determination of tropical trees, and monocotyledons in general, is not an easy task. Representatives of the Dracaena genus have survived in woodlands on dry margins of the Tethys tropical forest since the Tertiary Period. Here we present analyses ofDracaena cinnabari (DC) stand dynamics via direct and indirect methods of age determination. The direct method has taken advantage of historical photographs of DC mountain woodlands from Soqotra during an Austrian scientific expedition in 1899 by comparing these with the woodland stage in 2004. A decline in the number of tree individuals is obvious, but considering the little that is known about dynamics of DC woodland, one cannot simply state that such decline means forest destruction. The results fromthis direct method are compared to an indirect mathematical method of age determination using data from 2003. Indirect age determination values differed only about 6.5 % from those obtained with the direct method, indicating that the ind

    Dračinec - ohrožený stárnutím, nikoliv vyhynutím: dynamika hájů dračinců v horách Sokotry

  • Czech description

    Zjišťování stáří tropických stromů, natož jednoděložných stromů není jednoduchý úkol. Jedinci rodu Dracaena dokázali přežít na okrajích moře Tethys od třetihor až dodnes. Předkládaný článek se zabývá analýzou porostů Dracaena cinnabari pomocí přímé a nepřímé metody zjišťování stáří porostů. Výsledky přímé a nepřímé metody se liší pouze o 6,5 %.
