“…Despite the anthropophilic species such as brownheaded barbet, red-vented bulbul, and yellow-billed babbler [26,31] some forest loving birds such as Sri Lanka wood pigeon and emerald-collared parakeet [21] were observed to actively utilize resources available in these habitats. Although these observations are from our area of study, avian assemblages were typical to other neighborhood study systems available in literature [15,32,33]. The most important factors influencing avifaunal community structure were elevation, distance from the edge, and the canopy closure.…”

Distribution patterns corresponding to habitat characteristics in tropical forests have not been largely studied. Natural forest structure as well as the anthropogenic alterations to the forests equally affects the distribution patterns of wet zone avifauna. The study reveals the importance of % canopy closure, distance from the forest edge, tree density, diversity, and elevation to the community composition of local forest birds inhabiting Gannoruwa Forest Reserve, Sri Lanka. The most important factors resulting in the study for shaping the avian distribution pattern are distance from the edge,elevation, and the % canopy closure. With the increase of favouring resources to the avian fauna at the edges and the juxtaposition of the edge, many forest loving species were observed to move towards the edge. The pattern is proven advantageous, but harmful in the long run. Thus, it is advisable that the conservation plans should focus on habitat destruction and the anthropogenic disturbance along forest edges.

“…Limited research associated with terrestrial ecosystem biodiversity and ecosystem services attempted to estimate the composition of income in the peripheral communities from forest products [51,[63][64][65] but a proper assessment of ecosystem services and biodiversity in Sri Lanka's diverse terrestrial ecosystems is lacking. On the other hand, we found some studies related to biodiversity assessments in remote locations of Sri Lanka [55,57,66] but studies covering and discussing the interrelatedness of ecosystem services in all the climatic zones of Sri Lanka were rare or there were none.…”

“…One of the most rapidly emerging threats to food and livelihoods is the loss of biodiversity from traditionally species-rich agroecosystems [65] due to development projects, increased monoculture, and urbanization. However, these significant changes often go unnoticed because conventional conservation efforts repeatedly focus on endemic or charismatic species and intact ecosystems [73].…”

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.

“…The bird species were surveyed using a standard fixed radius point count method (Subasinghe et al, 2014) with the radius set at 25m, during most active 6:00 to 9:00 hr period and bird composition was identified up to the species level using the Birds guide (Kotagama and Ratnavira, 2010).…”

Water regimes and ecosystem in lowland paddy field: a case study in Awlegama, Kurunegala, Sri Lanka

Paddy fields are manmade ecosystems. These fields undergo three water regimes namely, aquatic, semi aquatic and terrestrial within a cultivation season. Accordingly, the ecosystem also changes. In addition, agronomic practices can affect biodiversity and the overall ecology. A study was conducted to assess the water regime and respective ecosystem so that ecosystem can be enhanced as an adaptation for climate variability in paddy cultivation. The study was conducted in a command area of Bayawa minor irrigation system located in Awlegama Agrarian service division in Kurunegala District, Sri Lanka. Six randomly selected locations in the field were used in the fauna survey at different growth stages in Yala season in 2015. A water management index (WMI) was developed to assess the water regime using physical factors of the field and social capacity of farmer. Results revealed that wet condition is expected in more than 69% of farmers since their WMI is more than 0.5. Water regime varied among head, middle and tail sections. Tail end of the command area has more reliability for water than the head and middle sections. The water fluctuation leads to higher biodiversity. The initial water regime and crop growth stages have provided more habitats for the both terrestrial and aquatic invertebrates.The abundance of aquatic invertebrates were significantly (p= 0.01) varied over the five growth stages anddragonflies' diversity was varied temporarily with respect to the species richness.Alternative wetting and drying have created more favorable habitats for aquatic fauna to increase the biodiversity of the fields. Increase of biodiversity promotes naturally enemies/predators for pests while aquatic fauna improve the nutrient availability in the fields. Therefore, water management in the fields could be used to enhance biodiversity in the rice field to achieve sustainable paddy cultivation.
