Abstract AR
هذا البحث عبارة عن دراسة للتوالد الطبيعي للأنواع الخشبية في منطقة الدراسة.
و الأهداف الأساسية للدراسة هي اختبار التوالد الطبيعي و نمو الأنواع النباتية القائمة.
ثم تحديد كثافة التوالد الطبيعي في (42) مربع عينة.
كما أفادت الدراسة بأن كثافة التوالد الطبيعي للأنواع الخشبية يتراوح ما بين 464-286 شتلة في الهكتار.
كما أوضحت الدراسة أن معدلات التوالد الطبيعي بطيئة جدا و ذلك نسبةً للضغط الحيوي المكثف و يتمثل في إدارة الممارسات الزراعية، الرعي الجائر.
كما أوضحت الدراسة أيضا أن الأنواع السائدة في التوالد هي السمرAcacia tortilis subp.
Spirocapa و السيال Acacia tartilis subsp.raddiana الأنواع ذات التوالد الطبيعي الضعيف هي الهجليج Balanites aegyptiaca،اللعوت Acacia orefota، الكتر Acacia mellifera، طندب Capparis decidua، الطلح Acacia seyal، و السرح Mearua crassifolea.
Abstract EN
Observations were presented on the natural regeneration of woody species at the study area.
The main objectives of this study were to examine: survival of newly recruited seedlings and saplings of woody species.
Growth and survival of established plants.
Populations of new seedlings were monitored throughout the study area.
A total of 42 plots, with 10x 10 m each, were studied.
Natural regeneration of 10 woody species at the study area was recorded, with density ranging between 286- 464 seedlings/ha.
The natural rates of regeneration have been very slow due to intense biotic pressure (agricultural management practices, overgrazing, fuel wood and fodder).
The most dominant regenerating species were Acacia tortilis subsp.spirocarpa and Acacia tortilis subsp.raddiana.
The other woody species with poor regeneration were Balanites aegyptiaca, Acacia orefota, A.mellifera, Capparis decidua ,A.seyal var.
seyal, and Maerua crassifolia.
