"การกระจายพันธุ์ของพืชต่างถิ่นที่รุกราน ในพื้นที่ป่าอนุรักษ์บ้านโปง อำเภอสันทราย จังหวัดเชียงใหม่The study of the distribution of invasive plants in Bann Pong Conservation Forest, Sansai District, Chiangmai Province was conducted during March 2017-September 2018. The objectives of this research were to study plant invasive distribution, species index, and invasion. Two characteristics of activities, more and less, areas were chosen for sample plots. It was found that ten species of invasive plants distributed in the area; Mikania cordata (Burm.f.) B.L.Rob., Bidens pilosa Linn., Crassocephalum crepidioides, Mimosa diplotricha C. Wright ex Sauvalle, Chromolaena odorata (Linn.) R.M.King & H.Rob., Ageratina adenophora Sieber ex Steud., Penisetum pedicellatum Trin, Imperata cylindrical Linn., Paederia foetida Linn. and Pennisetum polystachyon (L.) Schult. There were 5 species widely distributed in both sites; Crassocephalum crepidioides S.Moore, Chromolaena odorata (L.) R.M.King & H.Rob., Ageratina adenophora (Spreng.) R.M. King & H. Rob., Pennisetum pedicellatum Trin.) and Paederia foetida L. The sample areas with high activities, open space, and more light were more suitable for invasive distribution than the fewer activities areas.". มหาวิทยาลัยแม่โจ้. 2560
