2008年度清除紅樹樹苗工作

自1985年起，世界自然基金會每年均於觀鳥屋前的潮澗帶泥灘進行清除紅樹樹苗的工作。此項工作對維持泥灘作為水鳥覓食地、生態研究、教育及觀鳥地點，尤其重要(圖1)。

本會職員及外判承辦商將今天起至10月進行清除紅樹樹苗的工作。此項管理工作由漁護署監察，並連同地政署，就基金會每年提交的影響評估報告，批准進行。

本會職員及外判承辦商將只於后海灣退潮時份，亦即觀鳥屋前的水鳥數目極少時進行工作。請不要誤以為他們是非法漁民！你將見到他們把紅樹樹苗踩進泥中，漁民絕不會這樣做。

如欲查詢進一步資料，請聯絡米埔自然保護區李嘉慧或施百納，電話：2471-6212。

與此同時，漁護署的外判承辦商亦在泥灘進行清除海桑的工作。海桑是入侵性外來品種，除了能極快侵占泥灘，減少水鳥覓食地之外，研究亦發現牠們會與原生紅樹品種互相競爭，為原生種帶來不良影響。

Mangrove Seedling Clearance Works - 2008

Every year since 1985, WWF has cleared mangrove seedlings from the area of inter tidal mudflat in front of the floating bird-watching hides. This is necessary to maintain the area as a valuable feeding habitat for waterbirds as well as to promote ecological research, education and birdwatching (Figure 1).

WWF staff and contractors will commence the 2008 clearance works today and continue through to October. Our work is monitored by AFCD, who together with Districts Lands Office, give us their consent each year upon approval of a WWF impact assessment report.

Our staff and contractors will only work during periods of low tide when the waterbirds in front of the hides are very few in number. Please do not mistake these workers for illegal fishermen! You will see them stepping seedlings into the mud, something the fishermen would not be doing.

If you require any further information please telephone the WWF Mai Po Office on 2471-6212 and ask for either Janet Lee or Bena Smith.

At the same time, AFCD's contractors are working on the Sonneratia tree removal work on the mudflat. Sonneratia is an invasive exotic mangrove species which is found to out-complete the native species and can quickly invade the mudflat area, reducing the feeding area for waterbirds.
