Abstract

1 Forest Research and Training Centre, Pokhara, Gandaki Province, Nepal. *Email: raj_malla@yahoo.com 2 Forest Research and Training Centre, Kathmandu, Nepal 3 International Centre for Integrated Mountain Development, Lalitpur, Nepal Large-scale plantations of pine species were done in the bare hills of the Middle Mountain region of Nepal during the early 1980s. There is a growing concern on the sustainability of the planted pine forests in the country due to the presence of invasive alien plant species (IAPS). Invasive alien plant species are considered as one of the drivers of forest degradation and deforestation. Ageratina adenophora is one of the problematic IAPS found in the planted pine forests throughout the country. In this study, we employed different treatments to control the invasion of A. adenophora in the planted pine (Pinus patula) forest. The research design included four different treatments, viz., (i) control, (ii) stem felling, (iii) floor clearance, and (iv) stem felling cum floor clearance in one block (Block I), which was replicated in another block (Block II). The data were collected using circular sample plots with 2m radius. The ANOVA and TukeyHSD Tests were applied during the analysis process so as to determine the effects of treatments on invasion of A. adenophora. The "floor clearance treatment" was found to be significantly effective to reduce the presence of A. adenophora in the planted pine forest. On the contrary, the "opening of forest cover treatment" was found to be conducive to this invasive species to invade the area. The "stem felling cum floor clearance treatment" could be an effective strategy to control invasion of A. adenophora in planted forest, but as it demands a high cost, it is likely to be appropriate for small forest areas where promotion of regeneration is of high priority.
紫茎泽兰对尼泊尔人工林入侵的评估
1森林研究和培训中心,尼泊尔甘达基省博卡拉*电子邮件:raj_malla@yahoo.com2尼泊尔加德满都森林研究和培训中心3尼泊尔拉利特布尔国际山地综合发展中心20世纪80年代初,在尼泊尔中部山区的裸露山丘上进行了大规模的松树种植。由于外来入侵植物物种的存在,人们越来越担心该国人工松林的可持续性。外来入侵植物物种被认为是森林退化和森林砍伐的驱动因素之一。紫茎泽兰是在全国各地种植的松林中发现的有问题的IAPS之一。在本研究中,我们采用不同的处理来控制紫茎泽兰在人工松(Pinus patula)林中的入侵。研究设计包括四种不同的处理方法,即(i)对照、(ii)树干砍伐、(iii)地面清理和(iv)在一个区块(第一区块)中进行树干砍伐兼地面清理,并在另一区块(第二区块)中复制。使用半径为2米的圆形样地收集数据。在分析过程中应用ANOVA和TukeyHSD测试,以确定治疗对紫茎泽兰入侵的影响。研究发现,“地面清除处理”对减少人工松树林中紫茎泽兰的存在非常有效。相反,“开放森林覆盖处理”被发现有利于这种入侵物种入侵该地区。“树干砍伐兼地面清理处理”可能是控制紫茎泽兰在人工林中入侵的有效策略,但由于成本高,它可能适用于促进再生至关重要的小林区。
