Resort development and coastal beach erosion have led to declines in beachbreeding habitat for the near-threatened Malaysian Plover (Charadrius peronii) in the Gulf of Thailand.Semi-natural saltflats may provide supplementary nesting areas. We compared theenvironmental conditions, incubation behaviour and nesting success of ploversbreeding on sandy beaches and saltflats in Thailand. In total we monitored 21and nine nesting attempts in 2004 (beaches and saltflats, respectively) and 26and 22 nesting attempts in 2005. Despite higher air temperatures in thesaltflats (P < 0.0001), wedetected no significant differences in nest attendance (P = 0.542 and P = 0.885 for2004 and 2005, respectively), number of incubator changes between parents(P = 0.776 and P = 0.823) or number of parental nest departures (P = 0.087 and P= 0.712) during 120 incubation observations on 55 nests. There was also nodifference in hatching success between beaches in 2004 (beach = 0.65, saltflat =0.55; P = 0.692, n = 26) and 2005 (beach = 0.46, saltflat = 0.35; P = 0.539, n =41). These results suggest that saltflats may provide nesting habitat forMalaysian Plovers and could help enhance overall hatching success rates byreducing nesting densities on beaches. Although there are few remaining intactsaltflats in coastal Thailand, there are currently vast areas of abandoned tigerprawn aquaculture ponds that could be rehabilitated into saltflats at relativelylow cost. Given the large area of disused aquaculture ponds throughout Thailandand South-East Asia and the substantial human pressure on coastal habitats,there could be considerable conservation benefits to the restoration ofaquaculture ponds.
