Abstract

Taxus baccata Linn., commonly known as Yew is a temperate conifer tree usually small to medium in size. The barks, leaves, and twigs have traditional medicinal uses. It is also processed to make taxol which is used in the preparation of anti-cancer drugs (breast and ovarian cancer). The plant is rare, endangered, and listed in Appendix II of CITES. In this study, we used the maximum entropy (MaxEnt) model to predict the potential distribution of the species. The results show an area of 2444.01 km2 (88.77%) as least suitable, followed by 237.06 km2 (8.61%%) as moderately suitable and only 72.01 km2 (2.62%) as highly suitable category. The model performance was reasonably good and reliable with a mean Area under curve (AUC) of 0.934 and a standard deviation of 0.018. Isothermality, precipitation seasonality, and mean diurnal range of temperature significantly contributed to predicting the suitable habitat of T. baccata. An examination of the model results shows the northern part of the district is the potential area of occurrence for T. baccata in the natural stand and suitable for regeneration. Thus, the model outcomes could be used to explore the natural population status of the plant.
