【后海灣一分鐘】一、 甚麼是濕地保育區 (WCA) 和濕地緩衝區 (WBA) ?

2019/1/31 — 15:47

后海灣濕地及泥灘是各種水鳥及冬候鳥的重要覓食地及棲息地。七八十年代期間,米埔沼澤區逐漸獲得香港法例的保護,並邀請世界自然基金會積極管理該區的生境。但直至 1997 年「后海灣地區魚塘生態價值研究」完成後,政府才正式確認魚塘具有重要的生態價值。事實上,魚塘與米埔沼澤區在生態上具有緊密的關連,是后海灣濕地生態系統的一部分。因此,我們應同時保育后海灣相連的濕地及魚塘,包括豐樂圍、南生圍、甩洲、新田、馬草壟等地區,以維持其生態完整性。

隨著后海灣一帶的發展壓力增加,城市規劃委員會(城規會)為后海灣制訂規劃指引(規劃指引編號12),並成立「濕地保育區 (Wetland Conservation Area) 」及「濕地緩衝區 (Wetland Buffer Area) 」,以規管在后海灣地區的土地使用和開發。 濕地保育區旨在保護由大小不一但相連的魚塘所組成的核心區域,而濕地緩衝區則是以保護濕地保育區為目標的緩衝區。 在濕地保育區內,除非是保育該區的生態環境,或具有絕對壓倒性的公眾利益而必須進行的基礎設施項目外,不容許任何新發展。濕地緩衝區則在不損害濕地保育區魚塘生態價值的前提下,或許容許一些住宅或康樂發展,以移除現有的開放式存儲用途和恢復一些被破壞的魚塘。

本會認為任何發展項目都必須嚴格遵守濕地保育區/濕地緩衝區的規劃管制,以保護后海灣濕地生態系統的生態完整性。

【Deep Bay In A Minute】1. What is WCA and WBA?

The Deep Bay wetlands and mudflats is a globally recognized foraging and roosting ground for waterbirds and other migrant winter birds. The Mai Po marshes were gradually protected under Hong Kong legislation and actively managed during the 1970s and 80s. Yet, it was not until the Study on the Ecological Value of Fishponds in the Deep Bay Area completed in 1997 that formally recognized the ecological value of fishponds. In fact, the fishponds are ecologically connected to the Mai Po Marshes and form an integral part of the Deep Bay wetland ecosystem. Therefore, the continuous and adjoining wetlands and fishponds in the Deep Bay, including such areas as Fung Lok Wai, Nam Sang Wai, Lut Chau, San Tin and Ma Tso Lung should be conserved in order to maintain its ecological integrity.

As the development pressure increased, the Town Planning Board established the “Wetland Conservation Area” (WCA) and “Wetland Buffer Area” (WBA) to regulate applications for different land use and development in the Deep Bay Area. Under the Town Planning Board Guideline No 12 the WCA was designated to conserve the core area which consists of continuous and adjoining fishponds, while WBA was designated as a buffer zone to protect the WCA. No new development is allowed within the WCA unless it supports nature conservation in the area or is an essential infrastructure with overriding public interest. Residential or recreational development in the WBA, which helps to remove the existing open storage use and/or to restore some of the fishponds and would not have adverse ecological impacts on the WCA may be allowed.

HKBWS considers that the WCA/WBA planning control should be strictly followed in order to conserve the ecological integrity of the Deep Bay wetland ecosystem.
