Long-Term Socio-Ecological Research Programme

The Long-Term Socio-Ecological Research Programme (LTSER) is an NParks programme launched in 2021 to monitor, document, and understand socio-ecological change in Singapore over long timescales. It brings together interdisciplinary projects that use dedicated study sites and repeated measurements to generate evidence for science-based solutions, policies, and programmes. LTSER is one of a small number of tropical long-term ecological research programmes with an urban focus (NParks, LTSER Programme).

Three focal domains

LTSER research is organised around three focal domains. Urban biodiversity examines the diversity and distribution of organisms in natural ecosystems and urban green spaces, supporting long-term conservation under urbanisation and climate change. Biogeochemical and biophysical research studies the flows and stocks of carbon, nutrients, water, and energy, including how City in Nature initiatives affect ecosystem resilience and nature-based solutions. Socio-behavioural research examines changes in values, beliefs, social norms, behaviour, human-nature relationships, well-being, social cohesion, national identity, and environmental stewardship (NParks, LTSER Programme).

The long-term approach matters because ecological processes operate across broad spatial and temporal scales. Repeated observations can reveal trends and relationships that a one-off survey cannot establish, while comparisons across natural, managed, and built-up settings can help identify how environmental and human drivers interact.

Study sites and spatial scales

NParks lists nine designated terrestrial long-term sites: Bukit Timah Nature Reserve; Central Catchment Nature Reserve including Nee Soon Swamp Forest; Sungei Buloh Wetland Reserve together with Mandai Mangrove and Mudflat; Singapore Botanic Gardens; Bishan-Ang Mo Kio; Jurong Lakeside District; Pulau Ubin; Bukit Batok-Tengah Nature Corridor; and Sungei Kadut-Kranji (NParks, LTSER Programme). Site selection reflects ecological significance, proximity to key green areas, existing long-term data, and anticipated changes associated with City in Nature initiatives.

Projects can also compare multiple sites along a natural-to-built gradient or examine change at city or population level. The nine-site figure is therefore the designated terrestrial-site list, not a limit on every spatial scale used by LTSER research.

Ongoing projects and status

NParks currently lists five ongoing projects. They cover long-term forest ecological monitoring; mammal and bird diversity and plant-frugivore interactions; phenological monitoring at the Singapore Botanic Gardens; shorebirds and passerines at Sungei Buloh, Mandai Mudflat and other wetlands; and long-term socio-behavioural impacts of City in Nature (NParks, LTSER Programme). The five-project count is the current page listing, not a lifetime award total or a claim that every project has completed its research outputs.

NParks currently states that there are no ongoing grant calls for LTSER. The programme should therefore be distinguished from an open public grant scheme or a one-time biodiversity survey. Its purpose is to maintain coordinated long-term evidence that can support ecological management, climate resilience, and social understanding of Singapore's City in Nature transition.
