West Rail runs through the very rural Kam Tin Valley, home to two rare species: the narrow-mouthed frog and the painted snipe.
A study is just starting to establish whether the snipe, a freshwater wetland bird, feeds as well as breeding in the wetlands. A new 12ha habitat is to be created.
Though the frog is less rare than first believed (its status is being downgraded from rare to uncommon) the new habitat is being designed with it too in mind.
