Abstract

Abstract Morni Hills of Panchkula district, Haryana harbor floristically important tropical dry deciduous forests and are quite enriched with the phytodiversity of medicinally important plant species. But these forests are under huge pressure due to anthropogenic activities facilitating the establishment and spread of invasive plant species. So, the present study was conducted in the forests of Morni Hills to understand the ecology of invasive alien plant species growing there. During the study, the area was colonized by many invasive alien plant species, such as Ageratum conyzoides L., A. haustonianum Mill., Chromolaena odorata (L.) R.M. King & H. Rob., Lantana camara L., etc. In terms of longevity, the annual growth form dominated over the perennial. The family Asteraceae was dominant with 11 species, followed by Malvaceae and others. The biological spectrum showed that the dominant life form was therophytes followed by phanerophytes and others, indicating vegetation disturbance while during flowering phenology assessment, maximum plant species were found to be flowering throughout the year. Using the data of flowering (presence or absence), a hierarchical cluster analysis was carried out and a heatmap was prepared. The diversity of invasive plants was calculated along an altitudinal gradient and was found to be changing along with rising altitude in a hump-shaped pattern. The invasive alien plant species cause severe threats to the forest ecosystems. Hence, by policy planning and adopting appropriate management strategies in the forests of Morni Hills, the growth of invasive alien plant species should be controlled to retain the natural ecology of the area.
热带干燥落叶林中入侵植物的生物光谱、物候和多样性研究
哈里亚纳邦Panchkula地区的Morni Hills拥有重要的热带干燥落叶林,具有丰富的药用植物多样性。但由于人为活动促进了入侵植物物种的建立和传播,这些森林面临着巨大的压力。因此,本研究在莫尼山的森林中进行,以了解生长在那里的外来入侵植物物种的生态学。在研究期间,该地区有许多外来入侵植物,如Ageratum conyzoides L., A. haustonianum Mill.。,臭草(L.)R.M. King和H. Rob。Lantana camara L等。在寿命方面,一年生生长形式优于多年生生长形式。菊科为优势科,共有11种,其次为锦葵科等。生物谱显示,植物的优势生命形式为植生植物,其次是显生植物和其他植物,表明植被受到干扰,而在开花物候评估中,全年开花植物种类最多。利用开花数据(有无开花)进行分层聚类分析,绘制热图。入侵植物多样性沿海拔梯度进行了计算,并发现随着海拔的上升,入侵植物多样性呈驼峰状变化。外来植物的入侵对森林生态系统造成了严重的威胁。因此,应通过政策规划和采取适当的管理策略,控制外来入侵植物的生长,以保持该地区的自然生态。
