香港所有的蝙蝠均受到《野生動物保護條例》（第170章）的保護。蓮麻坑鉛礦場為蝙蝠提供了一個不受干擾的棲息場所，也擁有香港最重要的蝙蝠群落。礦場於冬季也為大量種群的蝙蝠提供庇護，例如長翼蝠尼泊爾亞種和大長翼蝠（在香港發現的品種）等超過2000多隻蝙蝠。蓮麻坑鉛礦場還為這兩個物種和為以下五個物種提供了夏季繁殖地：包括中華鼠耳蝠、大足鼠耳蝠、小菊頭蝠、中華菊頭蝠和棕果蝠。
在1872年後，短吻果蝠被重新於蓮麻坑鉛礦場被發現。這種特殊的果蝠作為種子傳播的媒界，具有重要生態作用。蓮麻坑礦場也是重要的歷史遺跡之一，記錄了香港採礦歷史上的傳奇故事。

All bats are protected in Hong Kong under the Wild Animals Protection Ordinance Cap.170. The galleries at this site provide an undisturbed resting ground for bats and has become one of the most important bat colonies in Hong Kong. The galleries harbour large winter populations of Miniopterus schreibersii fuliginosus (Coomon Bent-winged Bat) and Miniopterus magnater macroden (Greater Bent-winged Bat, a species discovered in Hong Kong) numbering more than 2000 bats. The site also provides a summer breeding ground for these two species and the following five species:
- Myotis myotis chinensis (Large Mouse-eared Bat)
- Myotis ricketti (Ricketts Big-footed Bat)
- Rhinolophus pusillus (Least's Horseshoe Bat)
- Rhinolophus rouxi sinicus (Rufous Horseshoe Bat)
- Rousettus leschenaulti (Leschenault's Rousette Bat)

Rousettus leschenaulti was re-discovered in this site after Hong Kong's lsat record in 1872. This particularfruit bat may have an important ecological role to play as a seed dispersal agent in local habitats.
Lin Ma Hang Lead Mine is also an important historical relic representing one of the most extensive systems in Hong Kong's mining history.
