Geographical Attributes Analysis for Egyptian Hypericum Sinaicum
Journal Title: Universal Journal of Environmental Research and Technology - Year 2012, Vol 2, Issue 6
Abstract
A study was carried out on a wild herb Hypericum sinaicum (Family: Hypericaceae) in Saint Katherine Protectorate, South Sinai, Egypt to increase the understanding about some applications of Geographical Information Systems (GIS) in analysis, management and making suitable decisions in plant conservation strategies. Also to detect the effect of environmental factors (Topography) on the distribution of Hypericum sinaicum as well as geographical attributes. The results showed that it was found that H. sinaicum has a narrow range of distribution between 1515 and 2036 m. It was shown that the highest presence for H. sinaicum was in elevation between 1800-2000m (42.7%) and the lowest presence detected was at elevation between 1400- 1600m (0.8%). Extracted data came from 3d analysis by GIS found that H. sinaicum communities strongly affected by aspect and this shiny appears in the species distribution within special aspects. H. sinaicum was recorded at North East (44%), North (15.5%), East (15.5%), North West (13.8%), West (7.7%), South (1.7%), South East (0.8%) and Flat (0.8%), there was no records for the plant at the South West aspect. The slope degree of the populated sites was very high, as the species was found in slope aspect between 89.98 and 90 degree. Results showed that topography (elevation, aspect and slope) influences on physical and chemical properties of soil, plant morphology and plant community structure.
