“…Overall, invasive plants pose various impacts on the native biodiversity which could be summarized as follows: decrease in the diversity, density and abundance of the species (Kandwal et al 2009); replacing the economically and ecologically important fodder grasses, medicinal plants, etc. (Bughani & Rajwar 2005); favouring the invasion of other alien species over the native endemic species (Dobhal et al 2011); inhibiting the seed germination and growth of native flora (Bhardwaj et al 2014); reducing the nutrient content of the soil by altering the soil physico-chemical properties (Bhatt et al 1994) and homogenization of natural habitats (Dar & Reshi 2015, Pathak et al 2019.…”

“…They occur in practically all kinds of terrestrial ecosystems (Vitousek 1994) and comprise 20% or more of the continental flora and 50% or more of the island flora (Seabloom et al 2006, Sardans et al 2017). Among the different kinds of terrestrial ecosystems, montane ecosystems are considered to be at the lower risk of plant invasions due to the various ecological filters faced by the mountains as they move along high altitudes (Pauchard et al 2009, McDougall et al 2011, Pathak et al 2019.…”

“…The rapid expansion of the invasive plant species with/without human influence has resulted in drastic modifications of natural ecosystems, threatening various ecosystem functions and services (Gordon 1998, Uddin & Robbinson 2017. The invasion of exotic plant species could change entire ecosystems by altering physical, chemical and biological properties of the habitat, communities and ecosystems, by altering fire regimes, hydrology, nutrient cycling and other ecological processes (Pathak et al 2019). The introduction of a new species in a new area exerts a great effect on the structure and/or ecosystem functioning.…”

Biological invasion is considered as one of the major threats to native ecosystems. Here, we review the impacts of invasive plants on the physical, chemical and biological aspects of ecosystem functioning. Introduction of invasive plants impact ecosystems profoundly in a multitude of ways by modifying the physical (soil temperature, soil moisture, etc.), chemical (elemental composition, litter dynamics, nutrient cycles, allelopathy, etc.) and biological components (plant community structure, soil microbial biota and fauna). Most studies have shown a negative feedback of biological invasion on the physical, chemical and biological aspects of the ecosystems. Very often, a positive feedback has been generated between the physico-chemical and biological aspects that favour invasion success. Hence, the in-depth and long-term monitoring is needed to focus on the impact of invasive plants on the species diversity, soil biogeochemistry for better understanding of plant invasion processes in ecosystems, so that proper management strategies could be developed for combating the negative impacts of plant invasion.

“…The Himalayan region, one of the global biodiversity hotspots, is quite vulnerable due to climate change and other abiotic and biotic drivers of change including the rapid spread of IAS. Some of the most obnoxious IAS in this region includes Lantana camara , Ageratina adenophora , Parthenium hysterophorus , and Ageratum conyzoides [ 13 ]. During the past few decades increasing anthropogenic pressures such as unabated linear infrastructure development, uncontrolled tourism, livestock grazing, agricultural expansion and extraction of non-timber forest products (NTFPs) have led to the degradation of wildlife habitats and the spread of a large number of invasive species [ 14 ].…”

Ageratina adenophora and Lantana camara in Kailash Sacred Landscape, India: Current distribution and future climatic scenarios through modeling

The Himalayan region is one of the global biodiversity hotspots. However, its biodiversity and ecosystems are threatened due to abiotic and biotic drivers. One of the major biotic threats to biodiversity in this region is the rapid spread of Invasive Alien Species (IAS). Natural forests and grasslands are increasingly getting infested by IAS affecting regeneration of native species and decline in availability of bio-resources. Assessing the current status of IAS and prediction of their future spread would be vital for evolving specific species management interventions. Keeping this in view, we conducted an in-depth study on two IASs, viz., Ageratina adenophora and Lantana camara in the Indian part of Kailash Sacred Landscape (KSL), Western Himalaya. Intensive field surveys were conducted to collect the presence of A. adenophora (n = 567) and L. camara (n = 120) along an altitudinal gradient between 300 and 3000 m a.s.l. We performed Principal Component Analysis to nullify the multi-colinearity effects of the environmental predictors following MaxEnt species distribution model in the current and future climatic scenarios for both the species. All current and future model precision (i.e., Area Under the Curve; AUC) for both species was higher than 0.81. It is predicted that under the current rate of climate change and higher emission (i.e., RCP 8.5 pathway), A. adenophora will spread 45.3% more than its current distribution and is likely to reach up to 3029 m a.s.l., whereas, L. camara will spread 29.8% more than its current distribution range and likely to reach up to 3018 m a.s.l. Our results will help in future conservation planning and participatory management of forests and grasslands in the Kailash Sacred Landscape–India.

The western Himalayan region is one of the unique biodiversity hotspots is rapidly getting invaded by alien invasive species and become a major management concern to save many economically and culturally important indigenous endemic species of this region. The present study aims to investigate the probable current and future apposite invaded habitat of Eupatorium ( Ageratina adenophora ) and Lantana ( Lantana camara ) in the Kailash Sacred Landscape-India in response to representative concentration pathways (RCP) 8.5 of global climate change. Intensive field surveys were conducted to collect the presence locations of Eupatorium ( n = 400 ) and Lantana ( n = 250 ) along the altitudinal gradient of 300 to 2500 masl that covers diverse vegetation and landscape features. We performed Principle Component Analysis to nullify the multi-colinearity effect of the environmental predictors followed by M axEnt species distribution model in the current and future climatic scenario of both the species. All current and future model precision for both these species was higher than 0.81 with the area under the curve (AUC). If the climate change continues to follow the higher emission RCP8.5 pathway, Eupatorium will spread 45.3% more of its current distribution area and will spread up to 3024 masl. Whereas, Lantana will spread 29.8% more of its current distribution area and will reach up to 3018 masl. The further distribution of this alien species may cause a serious threat to the local biodiversity results into a change in ecosystem processes and reduced ecosystem services in the area. Therefore, our current and the projected future map of their distribution will be helpful for local managers to take necessary action to overcome the adverse effect of this plant invasion in future.
