Dracaena cinnabari Balf. On The Soqotra Island is a spectacural relict of the Tethys tropical forest.

All seedlings are threatened by goats grazing. Age structure of Dracaena populations indicates maturity and overmaturity depending on browsing.The objective of this work is to predict growing dynamics of Dragon's Blood Trees in permanent sample plot at Firmihin, where there is the largest existing stand of Dracaena species.
