Abstract

The broad-scale inventories of alien species reveal macroecological patterns, but these often fall short in guiding local-level management strategies. Local authorities, tasked with on-the-ground management, require precise knowledge of the occurrence of invasive species tailored to their jurisdictional boundaries. What proves critical at the local scale may not hold the same significance at national or regional levels. In this context, we present a comprehensive inventory of alien vascular plant species across the ecologically diverse Jammu, Kashmir, and Ladakh (JKL) regions of India. Our study identifies 312 alien plant species belonging to 210 genera and 61 families. These alien plant species are predominantly herbaceous dicots. Of these, ca. 62% are naturalized, and 28% exhibit invasive behavior in the region. Introductions have been primarily unintentional, with a notable fraction (26%) introduced for ornamental purposes. The families with the highest number of alien plant species are Asteraceae (46 species), Fabaceae (28 species), and Amaranthaceae (23 species). The genera with the most species are Amaranthus (10 species), Solanum (8 species), Iris (7 species), and Oenothera (5 species). The Jammu region has the highest number of alien plant species, with 221 documented species, including 99 unique to this region. This is followed by the Kashmir Himalaya, with 212 alien species, 70 of which are exclusive to the area. In Ladakh, 76 alien species are recorded, with only one exclusive to the region. Fifty-five alien species are common across all three regions. In each region, more than 50% of species are naturalized, while invasive species constitute about 30% of the total. Therophytes are the dominant life-form category across all regions. Only 18% of species are shared across the three regions. Our findings emphasize the imperative of integrating local-scale knowledge into invasion management frameworks, ensuring targeted and effective strategies aligned with local administrative capacities. By bridging the gap between broad ecological patterns and localized management needs, our study advocates for a nuanced approach to invasive species management that accounts for regional and local specificity.

有效管理外来物种的地方清单:来自印度查谟、克什米尔和拉达克外来植物群的见解
大范围的外来物种清单揭示了宏观生态模式,但这些往往不足以指导地方一级的管理战略。负责实地管理的地方当局需要精确了解入侵物种的发生情况,并根据其管辖范围进行调整。在地方层面被证明至关重要的事情,在国家或地区层面可能没有同样的重要性。在此背景下,我们提出了一份全面的外来维管植物物种清单,涵盖印度生态多样化的查谟、克什米尔和拉达克(JKL)地区。本研究共鉴定出外来植物312种,隶属于61科210属。这些外来植物种类主要是草本菊科植物。其中,大约62%是归化的,28%在该地区表现出入侵行为。引进主要是无意的,有相当一部分(26%)是出于观赏目的而引进的。外来植物种类最多的科是菊科(46种)、豆科(28种)和苋科(23种)。种数最多的属分别是苋属(10种)、茄属(8种)、鸢尾属(7种)和野花属(5种)。查谟地区外来植物种类最多,有221种记录在案,其中99种是该地区独有的。其次是克什米尔喜马拉雅,有212种外来物种,其中70种是该地区独有的。在拉达克,记录在案的外来物种有76种,其中只有一种是该地区独有的。55种外来物种在这三个地区都很常见。在每个地区,超过50%的物种是归化的,而入侵物种约占总数的30%。植生植物是所有地区的主要生命形式类别。只有18%的物种在这三个地区共享。我们的研究结果强调了将地方规模的知识整合到入侵管理框架中的必要性,确保有针对性和有效的战略与地方行政能力相一致。通过弥合广泛的生态模式和局部管理需求之间的差距,我们的研究提倡一种细致入微的入侵物种管理方法,该方法考虑了区域和当地的特殊性。

期刊介绍: Environmental Monitoring and Assessment emphasizes technical developments and data arising from environmental monitoring and assessment, the use of scientific principles in the design of monitoring systems at the local, regional and global scales, and the use of monitoring data in assessing the consequences of natural resource management actions and pollution risks to man and the environment.
