Abstract
Seasonal variations in climatic factors have a great effect on growth parameters of most plant species. The importance of the recent investigation is to evaluate the grazing value and availability of development the desirable plants for feeding livestock around the year and its relationship with climatic factors. Therefore, this study was carried out in 1998/1999 – 1999/2000  to make survey to the plant vegetation at wadi El Natron – El Almeen road (East Marsa Matrouh) at 5 sites in that area. every wet and dry season to evaluate the vegetation structure throughout 25 chart quadrates (5*5m2 each ) . Correlation coefficient between some climatic factors (rainfall, temperature, and evaporation) and each of the different vegetation parameters within each of the vegetation types was calculated.
              The results showed that most of the pasture measurements such as coverage %, Frequency %, Abundance %, fresh and dry production (Ton/fed.) reached their maximum during dry seasons except plant density (plant/m2) was greater in wet seasons. The results indicated that fifteen species belonging to eleven families were found. The majority of these species were perennial plants. Anabasis articulate and Thymelaea hirsuta were highest dominnet comparing the other plants to its adaptability to dry conditions.
               Generally, positive correlation between rainfall and each of annual palatable species was found, adversely, temperature take an opposite trend, incase of unpalatable and perennial species, each of the climatic factors had variable effect on each of the vegetation measurements.
