Ecological Notes On The Floristic Composition And Endemic Species Of Saint Catherine Mountains, South Sinai, Egypt

Abstract

The present study is aimed at (1) giving complete list of all plant speciec growing in Saint Catherine mountains, (2) studying the relationship between species number and the amount of precipitation at the time of study (1992 -1994), and (3) reporting on the geographical distribution of the ten most endangered and endemic species in the study area. Presence / absence tests were applied to forty-five stands distributed in Saint Catherine mountains. Distribution and ecological data (including a detailed description of the microhabilals) of 221 species are given. The results show a positive correlation between the number of species and amount of precipitation in the mountain ecosystems and revealed the distribution pattern of ten endemic and endangered species growing within very limited area
