| Abstract: | Waterbird abundance and diversity is highly influenced by the productivity of its habitat. Remote sensing technique can be used to estimate productivity using NDVI as the surrogate. The present study examine the seasonal and interannual relationships between NDVI and waterbird abundance & diversity at two spatial scales in the Fuente de Piedra lagoon, Spain from 2000 to 2009 using time-series MODIS 250 m NDVI data. The NDVI has extracted at lagoon and 500 m buffer of the lagoon. The waterbird abundance has analysed based on body size, forage type and foraging habitat at individual species level and major waterbird guilds. The seasonal abundance of individual waterbird species is strongly correlated with forage type, body size and forage habitat while the interannual NDVI is moderately correlated with forage type and foraging habitat. The correlation of individual waterbird at the NDVI of the 500 m buffer of the lagoon was higher than the NDVI of the lagoon. The abundance of major waterbird guild is moderately correlated with the seasonal and interannual NDVI of the lagoon and the NDVI of 500 m buffer of the lagoon. The diversity of Anatidae family is strongly correlated with the NDVI of the lagoon and the NDVI of the 500 m buffer lagoon seasonally. The present study reveals that MODIS NDVI can be used as an efficient tool for monitoring seasonal and interannual waterbird abundance and diversity. Key words: Waterbird, Abundance, Diversity, MODIS NDVI, body size, forage type, foraging habitat, Anatidae. |
