除了需要因應農作物不同成長階段調整水流，我們同時亦會監察水質的變化。我們與香港教育大學合作，定期於水口沼澤的不同位置抽取樣本，測試水的溶解氧、酸鹼值和其他的參數。同學們首次踏足這片沼澤時舉步維艱，後來身手開始純熟，慢慢地更有效率了。有些位置需要躬著身、涉著水穿過一大片沼澤（圖二），才能達到水源位置。感謝他們不辭辛勞，我們才可以取得水口沼澤的水質數據，這些數據對於制定生境管理方案是必不可少。

In addition to managing water flow following the growth stages of the crops, we also maintain continuous vigilance over water quality. We have established a partnership with The Education University of Hong Kong to routinely test parameters such as dissolved oxygen and pH levels in the water sources within the Shui Hau swamp in different areas.

Initially, students found navigating the swamp to be quite challenging. However, their efficiency improved as they became more familiar with the environment. Accessing specific water sources even required them to bend low, wading through expansive taro fields (as depicted in Figure 2). Grealy appreciates their relentless efforts that we have managed to gather vital water quality data from the Shui Hau swamp. These data are integral to the development of a holistic habitat management plan.
