How to get the benefits of wetlands in places they don't grow naturally? Make artificial ones

SINGAPORE - At Pekan Quarry on offshore Pulau Ubin, a constellation of artificial wetlands maps the once-plain water surface.

The new habitats mean that creatures that would not have been found on an open expanse of water, such as waterhens, kingfishers and damselflies, can now be seen flitting among the reeds and cattails swaying in the wind. Herons and otters, too, have been seen there.
