| 中文摘要 | 沿海鹽田被認為是水鳥的重要棲息地。然而，一旦鹽分生產停止，這些地區的生態管理往往受到限制。建立長期監測計劃對於有效為保護管理計劃提供資訊至關重要。我們在台灣水鳥的重要越冬地布台鹽田進行了監測計劃，並分析了調查數據，以評估 30 種的種群趨勢（2016-2024 年）和水鳥豐度與環境因素。共有四種涉水鴨物種出現顯著下降，但在較大的空間尺度上沒有觀察到下降趨勢，表明鹽田可能已經變得不適合它們。水深和鹽度是影響水鳥豐度的最重要因素。水深與濱鳥和大型涉水鳥的豐度呈負相關，但與潛水鳥類呈正相關。涉獵鴨子在中等水深的鹽田中含量最高。海鷗和燕鷗使用水深小於 40 公分的鹽田。鹽度對大多數公會都有負面影響。渾濁度與潛水鳥類的數量呈負相關。潮汐影響了小型濱鳥，漲潮時出現更高的數量。我們建議優先考慮在布代鹽田中涉足鴨子作為保護目標。保持平均水深20-30公分，鹽度低於40 psu，可以為鴨子提供合適的環境。創造不同的水深和降低鹽度是有助於鹽田水鳥保護的一般管理措施。 |
| 英文摘要 | Coastal salt pans are recognized as important habitats for waterbirds. However, once salt production ceases, the ecological management of these areas is often limited. Establishing long-term monitoring programs is essential for effectively informing conservation management plans. We conducted a monitoring program in the Budai salt pans, a critical wintering site for waterbirds in Taiwan, and analyzed survey data to assess population trends (2016–2024) of 30 species and waterbird abundance with environmental factors. A total of four dabbling duck species showed a significant decline, but no downward trend was observed at larger spatial scales, indicating that the salt pans may have become unsuitable for them. Water depth and salinity were the most important factors affecting waterbird abundance. Water depth was negatively correlated with the abundance of shorebirds and large wading birds, but positively correlated with diving birds. Dabbling ducks were most abundant in salt pans with medium water depths. The gulls and terns used salt pans with water depths of less than 40 cm. Salinity had a negative effect on most guilds. Turbidity was negatively correlated with the abundance of diving birds. Tides affected small shorebirds, with higher abundance appearing during high tides. We recommend prioritizing dabbling ducks in the Budai salt pans as a conservation target. Maintaining an average water depth of 20-30 cm and salinity below 40 psu could provide a suitable environment for dabbling ducks. Creating varying water depths and reducing salinity are general management measures that contribute to waterbird conservation in salt pans. |
