Extent of plant invasions has been expected to be low in protected areas such as national parks due to low anthropogenic activities and high wilderness. However, recent researches across the world have revealed that plant invasions can be severe in the national parks with negative impacts on the protected species and ecosystems. Unfortunately, the status of plant invasions in the national parks of Nepal is mostly unknown. In this study, we sampled at seven locations inside the Parsa National Park (PNP) to document diversity and abundance of invasive alien plant species (IAPS) and their impacts on tree regeneration. Altogether, 130 quadrats of 10 m × 10 m were sampled. We recorded 14 IAPS in the PNP. Three of the IAPS (Chromolana odorata, Lantana camara and Mikania micrantha) were among the 100 of the world’s worst invasive alien species. C. odorata was found to be the most frequent IAPS with the highest cover. The frequency and cover of the IAPS were higher at the sites close to the settlements than at the sites away from the settlements. The species richness of the IAPS was also higher at the sites closer to the settlements than away. The sapling density of the tree species was found to have declined with the increasing cover of the IAPS suggesting that the IAPS had negatively affected tree regeneration. Our data revealed that the PNP has already witnessed massive plant invasions with widespread occurrence of three of the world’s worst invasive species. Therefore, it is high time to integrate management of invasive alien species in the management plan of the park.

One of the problems encountered by the Bukit Barisan Selatan National Park (TNBBS) is the presence of invasive alien species. Invasive alien species are plants that grow outside their natural distribution and have the ability to cover the area; hence it could suppress the growth of the other plants. The presence of invasive alien species in the national park has been widely reported to cause negative impacts on the ecosystem, local biodiversity, socio-economic, and human health in the vicinity. This study was carried out in the rehabilitation zone of the Sukaraja Atas Resort of TNBBS that had shifted into open land. This study aimed to determine the species and dominance of invasive alien species that exist. The sampling method was used by laying plots consisted of the combination of the line and multiple plot methods with a total plot of 25 plots. Data analysis was performed by selecting invasive alien species observed based related-literature, while the dominance of invasive alien species was calculated by the importance value index (IVI). The results identified 121 species, of which 29 species or 35% of them were classified as invasive alien, which originating from 19 families. Three invasive alien species become the most dominating, namely: Clidemia hirta with an IVI of 22.61, Imperata cylindrica with an IVI of 18.03, and Calliandra calothyrsus with an IVI 17.96. The environmental conditions and species characteristics supported the three invasive alien species domination; hence it inhibited the growth of native species. Keywords:  Bukit Barisan Selatan National Park, invasive alien species, rehabilitation zone

ABSTRACT A problem of global dimensions, the occupation of areas by invasive alien species is studied in this paper focusing on the increasing presence of Pinus sp in the Lagoa do Peixe National Park, at Rio Grande do Sul State, Brazil. From satellite imagery and the use of remote sensing and geoprocessing techniques, this paper presents a space-time mapping of the presence of this invasive alien species in the northern area of the Park, from 1985 to the 2017. Planted and disseminated areas of Pinus were mapped through visual analysis and pixel classification by the Spectral Angle Mapper (SAM) method, using images from the Landsat and Rapid Eye satellites. The results showed a constant growth rate in the areas of Pinus, with acceleration at the end of the analyzed period, confirming the invasive capacity of Pinus sp and the dispersion of their seeds by the wind. The excellent performance of the SAM algorithm in the identification of Pinus areas was demonstrated, as well as the importance of the use of satellite images in the analysis of the question.

Abstract Vachellia nilotica (Acacia nilotica), as an invasive alien species (IAS), was introduced to Baluran National Park from the Bogor Botanical Gardens in 1969. The purpose was for firebreak to prevent jumping fires from the savanna to the teak forests plantation. However, unexpectedly V. nilotica growth was uncontrollable and invaded the 6000 ha savanna. The rapid growth of this weed has killed the grass in the savanna leading to a decline in the Banteng population in Baluran National Park from 325 in 1998 to 22 in 2011. Since the 1980s, researche on V. nilotica control has been carried out by various universities and research institutions in Indonesia but has not yet obtained an effective and efficient control method. The study aimed to investigate the efficacy of herbicide with the active ingredient of triclopyr by stump brushing to control V. nilotica. Ten triclopyr herbicide concentrations with a solution of diesel and water were tested. The results showed that 1% triclopyr concentration in diesel oil could control 100% of V. nilotica weeds, while water solutions could only control 50% of V. nilotica weeds.

The Kruger National Park (KNP) has developed and refined a system of management called ‘strategic adaptive management’ (SAM), which rests on the concept of ‘threshold of potential concern’ (TPC). TPCs represent end-points in a continuum of change. When thresholds are reached – at which point concerns of negative impacts on biodiversity are raised – management options are explicitly considered and implemented. This paper describes the TPCs developed for monitoring and managing invasive alien species (IAS). More importantly, however, it describes the conceptual understanding, principles and hypotheses adopted as the foundations for setting these TPCs. In accordance with adaptive management practices, the TPCs will be revised as the ecological and conceptual understanding of invasions grows and information is gained through research in the KNP and elsewhere.Conservation implication: In accepting that species and systems are variable, and that flux is inevitable and desirable, these TPCs developed for invasive alien species specifi cally, provide end points against which monitoring can be assessed. Once a threshold is reached, the cause of the threshold being exceeded is examined and management interventions recommended.
