This study was conducted to know the visitation aspect of Limosa spp. and the roles of Nakdong River estuary as resting ground for Limosa spp. This study was conducted during the two periods for the early 1990s (May, 1989 to April 1993) and the mid-2000s (May, 2002 to April 2008) in order to assess the state of long-term monitoring of Limosa spp. in Nakdong River estuary, an area characterized by rapidly changing environment. Among the 9 genus, 27 species and 116,761 individuals observed during the study (May, 1989 to April 1993, May, 2002 to April 2008, total of 10 years), 1,071 individuals of the black-tailed godwit (Limosa limosa) and 3,214 individuals of the bar-tailed godwit (Limosa lapponica) of genus Limosa of family Scolopacidae were observed. 2 species observed was 4,285 individuals and which was 3.67% of total individuals observed. Among the case of the 2 species and 4,285 individuals of genus Limosa, 834 individuals of the black-tailed godwit and 2,216 individuals of the bar-tailed godwit, for a total of 3,050 individuals, were observed during the early 1990s (between years 1989 and 1993), and 237 individuals of the black-tailed godwit and 998 individuals of the bar-tailed godwit, for a total of 1,235 individuals, were observed during the mid 2000s. Comparison of the visitation aspects of the two periods did not show significant difference between the early 1990s and the mid-2000s (P<0.14), and the individuals observed in the early 1990s (Mean=762.50) were greater than those observed in the mid-2000s (Mean=205.83). The average number of individuals of the 5 regions was 41.17 individuals, with the average number of individuals being 136.83 individuals in Daemadeung (DMD), 14.33 individuals in Jangja Shinjado (JJ.SJD), 30.00 individuals in Saja Doyodeung (SJ.DY), 17.83 individuals in southern Eulsukdo (LUD) and 6.83 individuals in Eulsukdo (USD). Statistical analysis showed significant difference among the 5 sites (P<0.05). A total of 1,235 individuals were observed during 6 years, including 821 individuals in Daemadeung, 180 individuals in Saja Doyodeung, 107 individuals in southern Eulsukdo, 86 individuals in Shinjado and 41 individuals in Eulsukdo.
