Abstract: As biodiversity loss progresses to be an increasingly significant concern given societies’ reliance on natural resources and ecosystem services (De Groot et al., 2002, Cardinale et al., 2012), the use of conservation strategies to safeguard these resources and services provided by the natural environment are similarly growing in importance (Jordan, 1995). Among various conservation strategies, reserve site selection has been a favourable way to achieve conservation (Naughton-Treves et al., 2005). However, two main issues influence the effectiveness of conservation via protected areas or conservation sites. Firstly, conservation sites are often designated in an ad-hoc manner, without strategic planning to protect areas with the highest conservation potential (Pressey, 1994). Secondly, conventional conservation approaches often neglect the conservation value of nature spaces within the urban environment – spaces which can be both ecologically and socially important (Dearborn and Kark, 2010). In order to improve the effectiveness and efficiency of reserve site selection, Systematic Conservation Planning (SCP) has been conceptualised as a framework to identify conservation priority sites fulfilling defined conservation goals (Margules and Pressey, 2002). With urban biodiversity becoming increasingly important, cities like Singapore become important areas of focus. As such, this study focuses on applying the SCP framework to Singapore to demonstrate how its urban parks can be assigned relative quantitative values in terms of their importance for conservation, in turn exploring how these values may guide future land use planning. This study adopts the GIS-based Multi-Criteria Analysis (MCA) approach as a methodological framework to implement SCP. The outcomes of MCA indicated how conservation priority values can differ based on differing perspectives of decision-makers with regards to conservation objectives, suggesting interagency cooperation is beneficial for effective conservation planning. Results have also enabled discussions of possible future planning strategies, as exemplified by considering Pulau Ubin as a case study.
