Abstract
Habitat conservation is one of the most important issues facing the
environment today. However, in recent years habitat loss has attained a
fundamental importance for being the most severe threat to wildlife
across the globe (Brooks et al., 2002; Smith &Smith, 2003).
Many species globally are threatened due to changes in landscape structure which have been driven by anthropogenic activities, such as over-grazing, deforestation, and urbanization at local and global levels are the cause of major crises that face the ecological community (Solbrig, 1994; Ohl et al., 2007)
This crisis has several negative effects for humanity, economies, health, environmental services, and moral and spiritual prosperity< Wilson, 2002). There is therefore an increasing demand of monitoring and developing Conservation strategies for sustaining biodiversity (Pinto et al., 2008). br>Biodiversity might affected by changes of various spatiotemporal scales, as well as biotic and abiotic conditions. A particular
change in environmental conditions may increase the diversity of one
subset of organisms within a community while decrease the diversity of a different group of organisms. Also understanding diversity requires understanding the processes that regulate the composition, the structure and ultimately the diversity of communities (Semida et al., 2001)
Egypt participates in most of the environmental issues of developing countries. Egypt’s environmental problems emerge from its dryness, irregular population distribution, scarcity of productive land, and Introduction 2 pollution. Egypt’s major problems include: loss of agricultural land (due
to urbanization and industrialization) has resulted in a very fast
deterioration of environment; desertification; oil contamination menacing
coral reefs, shores, and pelagic habitats (Hopkins, et. al. 2003; Tantawi, et. al. 2009; Hussein Salama, 2010 ; USAID, 2010.
