Abstract |
: |
This research presented a comparative study between two adjacent sectors ((Bhma Spihh)) Al-Baha, one inside the Hamma, and the other is open to grazing by sheep and goats. It should be mentioned that these two sectors has not previously had undergone such a study before. The comparison is made between those sectors over the four seasons during the period 1410/1411 his rank as follows: winter, spring, summer, autumn.
The comparisons Wim follows:
1) Vegetation:
A - plant species were counted in Balhama.
B - through the use of random squares method Random Quadrate been repeated plant knowledge sectors and thus the study was:
C - Measurement of density and production of vegetation.
D - was measured by the average height of shoots of these plants.
E - from the information gathered was the expense of the importance of each plant, hence the importance of community within the Hamma plant and beyond (IVI) Random Value Index.
2) soil
A - Fri soil from the center of each square random Random Quadrate, and bring samples to the lab was estimated:
B - amount dissolved in the water of calcium, potassium, magnesium, nitrogen and phosphorus.
C -% soil moisture (percentage).
D - electrical conductivity of the soil.
E - pH PH.
And - the strength of the soil.
Of the most important conclusions reached from the current research include:
A - Hamma successful system that maintains the range plants and helps to good use.
B - It also keeps the soil from erosion.
C - to preserve the Hamma plant diversity while preserving rare plants from extinction.
D - it is a base for several economic aspects, such as grazing, the pharmaceutical industry of medicinal plants, agriculture and tourism.
E - for all that must be revived and the development and dissemination of protected areas system in more parts of our Kingdom.
Z - show all of the results obtained, Hamma, where he was very rich pasture plants, soil has not washed it, and was rich in different plant species.
From the above we can say in short that further studies and follow-up to the pastures and reserves the demand holder, and to increase reserves and development of care of the demand dictated by the interest of humanity and the environment, and finally to prevent overgrazing should be the number of grazing animals commensurate with the capacity of the ecosystem in which they live. |
