تأثير طرائق إعادة تأهيل المراعي الطبيعية في الإنتاجية العلفية و التنوع النباتي في موقعي الشدادي و جبل وقارة المعزة في بادية محافظة الحسكة السورية

الملخص EN

The research was conducted in Spring of 2010 in Al Badia developing project of Alhasska province.

Two sites of rangelands rehabilitation (Jabal wakaret meazah and Shadadi ) were selected in order to study the effects of rangeland rehabilitation methods on Plant diversity, vegetation cover, plant density, forage productivity, and the frequency of species.

Three different methods of rehabilitation have been applied on these sites, transplanting of range plant, drill seeding and protection.

The biological attributes were recordeed by using modified double step method adopted by ACSAD.

The results Indicated to the positive effects of transplanting , and drill seeding methods, on the forage productivity and plant diversity, in comparison with protected areas for the two sites.

In Jabal wakaret meazah site, The forge productivity for transplanting sites were 203 -182 Kg/h and for drill seeding was 245 Kg/h in comparison with protected site 31 Kg/h.

In Shadadi site the result was the same; the foraage productivity for transplanting range plants and drill seeding were 552 and 672 Kg/h respectively in comparison with 209 Kg/h.

in protected site the plant diversity was increased in transplanting range plant and drill seeding.

However, the dominant species for most sites were annual grass and unpalatable plants except for two sites, in Jabal wakaret meaz ( drill seeding ) and Shadadi site (transplanting 2) .

Those results indicate also to inefficient protection method for rangelands rehabilitation of sever deteriorate rangelands because there is no seeds reserve of palatable perennial species in the soil.

Therefore, we recommended that for the rehabilitation deteriorated rangeland is to plant the suitable range species in order to increase the productivity and the biodiversity of species.
