Saving graces

The struggle to preserve Long Valley is destined to become an important chapter of Hong Kong's conservation movement. But that chapter may have a sad conclusion unless efforts to save the 36-hectare wetland are carried through to the end by putting in measures to maintain its ecological value forever.

Although the Kowloon-Canton Railway Corporation has been obliged to build a new rail line through the valley, at an additional cost of $2 billion - by means of a tunnel instead of a viaduct - fears remain that the site's environmental attributes could be jeopardised if farmers drained the land, which is privately owned, to push for commercial development. If they did, the huge cost of building the tunnel would be wasted.
