Methods

In the present study carried out in the country about 140 places of study site shorebirds the investigation of the environmental situation of the peripheral census and research site of Saunderss Gull Black-faced Spoonbill spoonbill common shelduck of endangered species. In addition in areas where freshwater of shorebirds is to try to concentrate also performs monitoring of paddy fields and agricultural arable land.? (?) Survey number of times: Based on the record of 10 surveys of the past to the Ministry of the Environment shorebirds population fluctuation monitoring survey conducted in the (1999 to 2002) site type has been selected by the following criteria: In the core site species in order to grasp the maximum number of each time more accurately perform three or more times per survey period. In other general site but three or more of research is desirable if difficult it may be a one-time survey. Selection criteria of core site 1 - Ramsar wetlands in the registration or the East Asia and Australia that are participating in the regional shorebirds important habitat network. 2 - that you meet the Ramsar criteria (Appendix ?). 3 - East Asia and Australia that the entry criteria of local shorebirds important habitat network is more than more meets. 4 - countries designated wildlife sanctuary or that has been designated as an important wetland 500. 5- is that track record that provided the data to the investigation of the national level. Record: In each study site counting start time and end time of the survey in the paper ( fill in the time close to the investigation time band) low tide time and high tide time to record the number of individual species of interest in the investigation range . In addition survey sites name study area code study site location to fill the investigator name. Each investigator is most of the selected the time zone in which the number of individuals can be counted to conduct a survey. Therefore in an environment where a tide such as tidal flats estuaries band investigation time is not matter whether it is at the time or low tide is at high tide.Aggregation of simultaneous investigation: The survey was conducted before and after 1 week (15 days) of simultaneous survey date and simultaneous investigation. Simultaneous investigation other than the survey date set to the time a lot of number of individuals in the study period. Spring and fall and winter of each one but is set to be carried out an investigation on the same day across the country this is by carrying out the count in the period in which to concentrate as much as possible snipes plovers that are brought over to Japan as a whole at some point in time Ru Dare to understand the majority of the total number of individuals of the kind. If we study all at once survey date it prevents the result by counting duplicate the same herd in a different place leading to the understanding of a more exact number of individuals . In particular in close proximity to the region study the combined date and time is desirable.Than shorebirds of observation record in the maximum number of counting each study site the maximum number of the things that was extracted the largest number for each species. This the maximum number of the investigation period by the (spring autumn winter) aggregated to to understand the seasonal changes and the annual change of the tri- state in each study site. Incidentally Aggregate subject is in all records obtained in the survey period the number of records used in the aggregate is not constant.? Unit of abundance = AggregatedCount, Unit of biomass = NA
