“…The results support the finding of a previous community-perception study reporting L. camara as one of the three most problematic IAPS in the natural ecosystems of central Nepal (Shrestha et al 2019b). Modification of the plant community structure and suppression of native plant species growth by L. camara have also been reported in India (Singh et al 2014), Africa (Jevon & Shackleton 2015) and Australia (Gooden et al 2009). In BNP, L. camara is currently prevalent mainly in the Babai River valley and Karnali floodplain, but it is highly likely that the weed will continue to spread to new areas within BNP and the surrounding landscape because species distribution models have predicted an increase in climatically suitable areas of L. camara in Nepal and Asia (Taylor et al 2012, Priyanka & Joshi 2013.…”

Summary Invasive alien plant species (IAPS) are spreading into protected areas worldwide; however, knowledge of these invasions and their impacts in Nepal’s protected areas is poor. Here, the spatial distribution pattern of IAPS in Bardia National Park (BNP), Nepal, was analysed using roadside surveys and grid sampling. The impacts of the most abundant IAPS, Lantana camara, on plant communities were analysed by comparing 60 pairs of non-invaded and invaded quadrats. Twelve IAPS, including two of the most prolific species globally, L. camara and Chromolaena odorata, were recorded from BNP. The Karnali floodplain in the south-western region of the park, a prime habitat of one-horned rhinoceros, was highly invaded by the IAPS. Tree canopy and distance to road, river and settlement were the major factors affecting IAPS occurrence. Lantana camara modified plant community structure and significantly reduced plant species richness and diversity; species richness of native plants was reduced to less than half in invaded plots. Plant invasions and impacts on native plant diversity have been increasing in BNP. We recommend management interventions involving immediate eradication of C. odorata and other species with single satellite populations and control measures for other widespread species such as L. camara and Ageratum houstonianum.

Lantana camara L. is an invasive alien shrub of worldwide significance due to its impacts on biodiversity. It can alter the soil properties of invaded ecosystems and, as a result, affect management outcomes. However, knowledge on the impacts of L. camara on soil properties is scanty, especially in South Africa, despite the pervasive presence of the plant in the country. In this comparative study, the soils underneath L. camara were assessed in order to determine if they had different properties (soil physico‐chemical properties, penetration resistance, infiltration, hydraulic conductivity and water repellency) in comparison to the soils in adjacent natural sites in the Eastern Cape, South Africa. Soil samples were collected from the top soil beneath the canopy of both L. camara‐invaded and adjacent natural sites in five different locations over three summer months. The soils that were collected from underneath L. camara had a significantly higher total C, total P, gravimetric soil moisture (in November and December) and were repellent, compared to the soils in the adjacent natural sites. Soil penetration resistance was significantly higher in the natural sites than in the L. camara‐invaded sites. The soil hydraulic conductivity, soil infiltration rate, soil pH, exchangeable cations and total N showed no significant difference between the invaded and the natural sites. It appears that the soils underneath L. camara have a high total C and total P, soil moisture and are repellent, thus influencing nutrient cycling, potentially making the soil properties underneath it ideal for its own growth. This could contribute to the success of L. camara as an invasive species.

Pristine tropical ecosystems are currently suffering under extreme demographic pressure. This has led to habitat destruction and disturbances, an important precondition for the invasion of exotic species into pristine ecosystems, with detrimental effects on biodiversity. In this study, we analysed the chronology of land cover changes along rivers in south-eastern Kenya using historical aerial photographs and current aerial pictures taken from a drone. We assessed quantity and quality of riparian thickets along these rivers in 1961, 1980 and 2015/ 2016 and analysed effects of fundamental land cover changes on arthropod abundance and diversity. Our data show effects from demographic pressure by the increasing number of human settlements rising by 425% from 1961 to 2015/2016 (i.e. from 36 to 189 settlements). 58.5% of the land surface originally covered by pristine riparian forests was cleared and transformed into agricultural land. After clearance and agricultural usage it frequently became fallow land and was invaded by the exotic shrub species Lantana camara. While the total coverage of riparian vegetation did not change over time, its quality declined dramatically. Currently 36.6% of the cleared pristine riparian forest is covered by L. camara thickets, and only 22.5% of the pristine riparian forest has remained unchanged over time. This modification of the vegetation structure impacts biodiversity. The abundances of three guilds of arthropods significantly differed between pristine and L. camara-dominated riparian vegetation, with herbivorous arthropods and ants being more abundant in pristine than in L. camara-dominated vegetation. Our data show that habitat destruction and disturbance is the prerequisite for subsequent invasion by exotic plant species, having a strong effect on species composition and diversity at higher trophic levels.
