... media (珠海自然資源 2021), but this report has yet to be verified. Based on AFCD’s unpublished data and communication with experts, populations of the Romer’s Tree Frogs at most of the natural and translocation sites in Hong Kong have been relatively stable, with occasional sightings in other localities (see...

... 2014 及 2015 年數目大幅上升後，2016 年的海豚 數目卻減少至較低水平。由於大嶼山西南面水域近年已成為海豚一個日益重要的 生境，該水域的海豚數量和趨勢需要密切留意。 中華白海豚在香港的平均群體數目、及覓食活動佔整體海豚目擊次數的比 率，均在 2016 年創下自 2002 年以來的新低，但此情況未知是否與人為活動造成 的干擾、或與海豚的食糧分佈與資源改變相關。幼豚的整體比率亦在 2016 年跌 8 至自 2002 年以來最低水平，牠們在去年的罕有出現，並在過去十五年出現的比 率持續下降，均顯示海豚出生率處於極低水平，此嚴峻的情況令人憂慮。 研究員於 2016-17 年間辨認出 150 隻個...

...新的「被動水底聲音監察項目」亦於本年度展開，主要是將名為 C-POD 的先進儀器，長期放置於海豚棲身環境中偵測及記錄牠們發出的卡嗒聲 音調。在為期一個月、位於龍鼓洲東面水域進行的試驗計劃中，於 813.7 小時的 監察裡共錄得 1,253 分鐘的海豚發聲紀錄；分析結果發現，海豚不分晝夜地使用 龍鼓洲水域作為其棲身地。由於此研究發現海豚在夜間甚為活躍，我們建議在還 未完全瞭解海豚在夜間的行為及棲息地運用以前，應不要貿然容許任何在海豚生 境內的工程在夜間進行，以確保海豚在夜間的發聲行為及覓食活動不受影響。 一項利用精密經緯儀、在陸上追蹤中華白海豚的移動模式及行為變化之研究 仍持續進行。在 2012...
