Population justification: Iqbal et al. (2013b) suggest the population may fall in the range 2,000-6,000 individuals, roughly equivalent to 1,333-4,000 mature individuals; placed here in the range 1,300-4,000 mature individuals. However, Java alone has been estimated to hold 2,000 individuals (Centurioni 2010), and with the much enlarged range now known it is likely that the population size is considerably larger than suggested by Iqbal et al. (2013b). If the species does occur as multiple subpopulations, the largest is therefore inferred to be larger than 1,000 mature individuals. 
During the ‘Big Month’ citizen science event (conducted in January 2020 comprising 22,054 checklists) across Java and Bali, the species was recorded in 132 (1.7%) of the 7,935 tetrads (2 × 2 km squares) visited (T. Squires and S. Marsden in litt. 2020), indicating a wide distribution around the coast.

Trend justification: There are no data on population trends. However,  Iqbal et al. 2013b (in Setiawan et al. 2019) had noted that records increased outside Java in recent years. This is potentially due to improved survey effort, or due to greater dispersal of individuals between islands in search of suitable habitat (brought on by rising pressure from coastal developments) (Iqbal et al. 2013b in Setiawan et al. 2019). Surveys on the Indralaya floodplain in southern Sumatra also noted an increasing trend between 2013 and 2018 (Setiawan et al. 2019). It is therefore possible that the species may see similar trends in other parts of its range. This however requires confirmation pending further surveys, particularly due to pressure from human disturbance, coastal development, and egg collection throughout the species's range. Therefore, despite not being at immediate risk, the Javan Plover is suspected to be stable or possibly declining.
