Métodos de Amostragem
The waterbirds species to be counted during the survey were defined according to Waterbird Population Estimates 3rd Edition (Wetlands International 2002), which is the document used by the Ramsar Convention for identifying wetlands containing internationally important concentrations of waterbirds.
| Área de Estudo | The area surveyed consists of the lakes and reservoirs shown within Anhui and Jiangsu Province, extending over a distance of about 200 km upstream of Hongze Hu. All the lakes visited are connected by channels or rivers to the Huai He. |

| Controle de Qualidade | Observers generally underestimate the numbers of waterbirds present when counting large flocks (Rappoldt et al. 1985). Underestimation is also compounded by the common problem of missing birds when counting over large wetland areas. As very large concentrations of waterbirds were not encountered during this survey, it is believed that count accuracy (identification of species and numbers) was good. It is also believed that few birds were missed at the individual count sites. At most lakes only part of the wetland could be surveyed and, therefore, counts for lakes are probably underestimates of numbers actually present. |
Descrição dos passos do método:
- The count was conducted by one team of two experienced counters each using Zeiss 10X42 Victory roof prism binoculars and Leica Televid 77 telescopes, with 20-60X zoom eyepieces. We used geo-referenced satellite images (15m/pixel) to select count sites and entered the coordinates into GPS units. This enabled us to reach the sites with minimum problems. Sometimes we could drive directly to the sites; on other occasions we hired a local truck or walked to the site. On all mornings we aimed to arrive at the first count site at about 07.00 when it was just light enough to see birds. We were able to survey through to about 17.30, before it got too dark to see. The ease with which we were able to reach wetland shores varied between lakes. In some cases there were dykes or roads around the wetland that allowed good views of potential waterbird habitat to be obtained, whilst the shorelines of other wetlands were difficult to reach which seriously limited our ability to adequately cover these in the available time.
