“…Nevertheless, some interesting and isolated studies conducted in different climatic zones targeting unique ecosystems were screened. One of those studies, focused on using species diversity to measure the ecosystem service conditions, showed how lichen diversity can be used as a bioindicator to measure the air quality of rural-urban ecosystems which is very significant as it demonstrates how unique species can contribute to ecosystem service management [69]. Moreover, as a country with a traditional indigenous medicinal system, Sri Lankan traditional medical practitioners have been using the vast floral biodiversity in healing processes, but we found only one published study that focused on the significance of plant biodiversity in the healing of snake bites, in which they found that 341 different plant species are utilized for traditional snakebite medication [70].…”

Tropical island countries are often highly populated and deliver immense ecosystem service benefits. As human wellbeing depends on these ecosystems, proper management is crucial in the resource-rich tropical lands where there is less related research. Though ecosystem service and biodiversity studies are a promising path to inform the ecosystem management for these mostly developing countries, published evidence of using ecosystem service studies in decision making is lacking. The purpose of this study is to provide an overview of ecosystem services and related research in Sri Lanka, examining trends and gaps in how these studies are conceptualized. Out of the considered 220 peer-reviewed articles, the majority of articles (48.2%) were terrestrial and forest related while coastal ecosystems were considered in 33.2% of studies. In most studies, the ecosystem service category studied was provisioning (31.5%) followed by regulatory service (28.7%). Studies investigating and quantifying ecosystem services, pressures on ecosystems, and their management were fewer compared to studies related to biodiversity or species introduction. Moreover, studies investigating the value of ecosystem services and biodiversity to the communities or involvement of stakeholders in the development of management actions regarding the ecosystem services were rare in Sri Lanka, and an intense focus from future studies in these aspects is timely and necessary.

“…Sampling of the plants is somewhat easy in isolated areas due to their availability and its tolerance towards the different types of pollutants [10][11][12]. Accumulation capacity of lower plants such as lichens and mosses were higher, but these organisms are rarely available in urban areas which are subjected to high level of pollution [13][14][15][16][17][18][19]. Nowadays, lower plants are replaced by higher plants for bio monitoring purpose [20,21].…”

Plant species can be utilized for biomonitoring the quality of the environment and reform the extent of pollution in both urbanized and industrial regions. In this current study, the quantity of nine heavy metal components viz. Al, As, Cd, Cr, Cu, Fe, Mn, Zn, and Pb absorbed on the leaves of Saraca asoca and Syzygium cumini were examined by using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) during “February-March, 2019”. The samples were gathered from six different sites namely, Vellagate (Site1), CSI hospital (Site2), Near Cancer Institute (Site3), Moongilmandapam (Site4), Collectrate (Site5), Pallavarmedu (Control Site 6), of the Kanchipuram town, Tamil Nadu State. Metals Fe, Al, Zn and Mn were identified on the leaves of S.asoca and S.Cumini in all sites with varying concentrations out of which Fe (234.49mg/kg) and Al (364.18mg/kg) were higher level. Pb was identified only on the leaves of S.asoca in the sites 2 (2.21mg/kg) and site 4 (2.81mg/kg) which are subjected to heavy traffic and Cu was found only in site 3 and site 4 with minimum levels. The metals such as As, Cd, Cr was not identified on both species in all selected sites. Absorption of heavy metals on the leaves was probably due to emissions from vehicle, nonemission sources and mainly from other man-made activities. This work showed that both the selected species S.asoca and S.Cumini were suitable bio indicators, bio-monitors and used as greenbelt around the industrial areas for the mitigation of pollutants in the environment.

“…Biomonitoring by plant species has been carried out in two ways as passive monitoring and active monitoring techniques, first one is by planting or introducing the sensitive plants and the later one is using the plants existing at present in the environment (Nakazato et al, 2018). Polluted sites specifically with various metal pollutants were monitored frequently by the lower plants such as mosses and lichens due to their more accumulation ability (Jiang et al, 2018 andYatawara andDayananda 2019). Nowadays, higher plants (trees) are widely accepted in urban areas with more levels of pollution where mosses and lichens are rarely distributed (Arslan et al, 2009;Khattak and Jabeen, 2012;Deepalakshmi et al, 2014 andMaghakyan et al, 2016).…”

Biomonitoring of heavy metals is one of the economic methods to identify and improve the quality of air. The aim of this work was to identify the concentration of nine heavy metals viz. Fe, Pb, Cu, Zn, Al, Cd, As, Cr and Mn in the ambient air deposited on the leaves of five tree species such as Saraca asoca, Terminalia catappa, Syzygium cumini, Ficus religiosa and Pongamia glabra collected from six sites such as Pallavarmedu (Site I), CSI hospital (Site II), Moongilmandapam (Site III), Collectrate (Site IV), Near Cancer Institute (Site V) and VellaGate (Site VI) of the Kanchipuram town of TamilNadu State, in the months of February - March 2019. Even with some differences in the concentration of nine heavy metals on the species, few were identified with significant correlation, suggesting that these pollutants were emitted from similar sources. The deposition of iron (235.53mg/kg) and aluminium (157.91mg/kg) were higher on the leaves of S.asoca compared with other species. The metals such as Cu, Cd, As, Pb and Cr were nil and not detected on the leaves, but Pb concentration was high (185.79 mg/kg) only on P. glabra at Site 2 and Cr (2.37 mg/kg) was found on the leaves of S. asoca at Site 1. The heavy metal dust deposited on the leaf surface was probably due to vehicular emission and other anthropogenic activities. The analysis showed that all the selected tree species acted as a biomonitor and should be grown that may help to improve the air quality of the area.
