19號基圍生境改善工程        
Habitat Enhancement Work at Gei wai #19

本年夏季19號基圍東面部份將進行生境改善工程，基圍中段的一條橫壆將被連接起來，把東面和西面分開。屆時西面靠海一方將灌進海水，東面靠岸一方將收集雨水，改為淡水濕地，作為兩棲類和蜻蜓的棲息地，而其中的蘆葦叢亦會復修為質素較佳的濕蘆葦叢，以供鳥類棲息。

改善工程預計於九月底完成，工程進行期間，若為閣下構成任何不便，本會謹此致歉。如欲查詢進一步資料，請聯絡米埔辦公室，電話：2471-6212。

This summer we are going to convert the landward end of Gei wai #19 into a rain-fed habitat by connecting the bund opposite to birdwatching Hide #3. The new rain-fed habitat will supplement Pond #24 in the southern end, serving as habitat for amphibians and dragonflies. Furthermore, wet reedbed will be restored to provide habitat for reedbed dependent birds.

Upon completion of the work at the end of September, the seaward end will be refilled with brackish water and the landward end with rainwater. We apologise for any inconvenience this may cause over the coming months. For further information please contact the Mai Po Office at 2471-6212.

泥灘莎草及紅樹樹苗管理工作2014
Sedges and Mangrove Seedling Management 2014

世界自然基金會每年於觀鳥屋前的潮澗帶泥灘，進行管理莎草及紅樹樹苗的工作。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。

今年，本會職員及外判承辦商將於7月開始此項工作，並於10月底以前完成。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。

為減低對水鳥的干擾，本會職員及外判承辦商將會於后海灣退潮時，亦即觀鳥屋前的水鳥數目較少時進行工作。如欲查詢進一步資料，請聯絡米埔自然保護區辦公室，電話：2471-6212。

Every year WWF carries out control of sedges and mangrove seedlings from the area of intertidal 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.

WWF staff and contractors will commence the 2014 works in July and will complete the work no later than the end of 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.

To minimise disturbance, our staff and contractors will only work during periods of low tide when fewer waterbirds are present in front of the hides. For further information please contact the Mai Po Office at 2471-6212.

23號基圍生境改善工程        
Habitat Enhancement Work at Gei wai #23

本年夏季23號基圍將進行生境改善工程，基圍中段的一條橫壆將被連接起來，把南面和北面分開。屆時南面一方將灌進海水，並維持淺水狀態，為水鳥提供棲息地；而北面將收集雨水，改為淡水蘆葦叢，以供依賴蘆葦叢鳥類棲息。

改善工程預計於七月開始，並於八月中完成，工程進行期間，若為閣下構成任何不便，本會謹此致歉。如欲查詢進一步資料，請聯絡米埔辦公室，電話：2471-6212。

This summer the northern end of Gei wai #23 will be converted to a rain-fed reedbed habitat by connecting the bund at the middle of the gei wai, so that rainwater can be collected above the existing operational water level. This will create a wet reedbed to provide habitat for reedbed-dependent birds. The southern end will continue to operate as a roosting area for waterbirds, with brackish water maintained at shallow depth.

The work will start in July and is expected to be completed by mid-August, we apologise for any inconvenience this may cause over the coming weeks. For further information please contact the Mai Po Office at 2471-6212.

13號基圍疏浚工程
Desilting Work at Gei wai #13

米埔的基圍按傳統運作方法，每月進行兩次換水，以助調節水溫和為紅樹、魚蝦等帶來養份。然而水流亦把后海灣幼細的泥沙帶到基圍中，日積月累令河道變得越來越淺，不適合魚蝦生長。因此，各個基圍需適時進行疏浚工程，以維持河道的深度並改善基圍水流。本年夏季13號基圍將進行疏浚工程，以大型挖泥機清除堆積在多條內河道及北面外河道的淤泥。

工程預計於十月底完成，工程進行期間，於7月及8月的平日可能需局步暫時關閉12及13號基圍之間的小徑。若為閣下構成任何不便，本會謹此致歉。如欲查詢進一步資料，請聯絡米埔辦公室，電話：2471-6212。

Following the traditional practice, water exchange is carried out twice per month at the Mai Po gei wai. This helps regulate the water temperature and brings nutrients to the mangroves, shrimps and fish in the gei wai. However, water exchange also carries silt from Deep Bay into the gei wai, which over time leads to the water channels in the gei wai becoming shallow and less suitable for the shrimps and fish. To reverse this problem, desilting work is carried out periodically in the gei wai to maintain water depth and facilitate water flow. The northern perimeter channel and the cross channels at Gei wai #13 are currently very shallow and will be desilted this summer.

During July and August, sections of the path between Gei wai #12 and #13 may need to be closed temporarily on weekdays. All work is expected to be completed by the end of October. We apologise for any inconvenience this may cause. For further information please contact the Mai Po Office at 2471-6212.

21號基圍生境改善工程        
Habitat Enhancement Work at Gei wai #21


21號基圍於2009年改造成開闊水域棲息地，於春秋為鴴鷸類提供潮漲棲息地，而在冬季亦為野鴨和鸕鶿使用。然而，靠岸的東面地區由於地勢較高和長期處於淺水狀態，原本的開闊水域漸漸被莎草科植物侵占。

本年夏季將進行生境改善工程，以推土機及挖泥機清除莎草，降低地勢以及修建數個適合水鳥棲息的小島。

我們現已將基圍放乾，以便於八月稍後開始工程。全個工程預計於十月底完成，工程進行期間，若為閣下構成任何不便，本會謹此致歉。如欲查詢進一步資料，請聯絡米埔辦公室，電話：2471-6212。

Gei wai #21 has been converted to open water habitat in 2009, serving as high-tide roosting area for shorebirds during spring and autumn, and at the same time attracting ducks and cormorants in winter. However, open water area at the landward side of the gei wai has been heavily invaded by sedges over the years.

Habitat enhancement work will be carried out with bull dozer and digger this summer. Sedges will be removed and open water area will be restored. A few small islands will also be constructed to attract waterbirds.

The gei wai has already been drained to facilitate the work which will be started later in August. The work is expected to be completed by the end of October, we apologise for any inconvenience this may cause over the coming months. For further information please contact the Mai Po Office at 2471-6212.
