أرى الكثير من المواضيع للكثير من المشاتل والأفراد الذي يحاولون بيع ونشر شجرة الباولونيا مستغلين جهل المزارع العربي بها وللأمانه الشجره لاينصح بنشرها ولا أدخالها للدول العربيه نظراً لطبيعتها الأجتياحيه والتدميريه فهي عدو شرس للنباتات المحليه حيث تنافسها على الموارد المائيه بسبب أنتشارها الرهيب في كل بيئه جديده تحل فيها.
الشجره تنتشر في جميع الطروف والبيئات وخصوصاً الرطبه منها وذات المسطحات المائيه كالدلتا في مصر ومزارع الرش المحوري في مصر والسعوديه والعراق وقد تنبهت ولاية كونكتكت لهذا ومنعت بيع بذورها بعد أطلاعها على الكوارث التي تسببت بها هذه الشجره في ست ولايات أمريكيه أخرى
Sale of the invasive Princess Tree is banned in Connecticut and it needs to be banned in all of the other states in which it has spread into natural areas. Continued sale of this plant is extremely irresponsible. If your local nursery is selling this tree, please inform them of how invasive and dangerous it is to our native ecosystems.

Invasive Species of Concern in Maryland (http://f.zira3a.net/ext.php?url=http%3A%2F%2Fwww.mdinva sivesp.org%2Farchived_invaders%2Far chived_invaders_2007_05.html)
Princess tree reproduces from seed, root sprouts and adventitious buds. A single tree is capable of producing an estimated 20 million seeds that are easily transported by wind and water. Seedlings grow quickly and flower within 8-10 years. This rapid growth and adaptability provides this tree with a competitive edge over native species in Maryland. Extensive colonies of princess trees have degraded native forest and riparian ecosystems, and its management difficulties make it a formidable enemy.
Once princess tree is established, it can be controlled using a variety of mechanical and chemical management techniques. Young seedlings can be hand pulled as soon as they are large enough to grasp. It is important to remove the entire root since broken fragments will re-sprout. Trees can be cut at ground level, but since Princess tree spreads by suckering, repeated cutting of re-sprouts or an herbicidal treatment may be necessary.

Paulownia tomentosa is an aggressive tree that invades disturbed natural areas including forests, roadsides, and stream banks

Princess tree is an aggressive ornamental tree that grows rapidly in disturbed natural areas, including forests, streambanks, and steep rocky slopes. It easily adapts to disturbed habitats, including previously burned areas, forests defoliated by pests (like gypsy moth) and landslides and can colonize rocky cliffs and scoured riparian zones where it may compete with rare plants in these marginal habitats

وللأخوه الذين يروجون لهذه الشجره ويكتبون نصف الحقيقه وهو أنها الأسرع نمواً .... نعم هي الأسرع نمواً والأكثر خطرا وللعلم الشجره الواحده ينتج عنها 20 مليون بذره تبقى حيه وفعاله لمدة ثلاث سنوات
تصوروا مصر بلا أشجار فاكهه أو العراق والسعوديه بلا نخيل .. هذا ماسينتج عن وجود هذه الشجره
