personally i think the "wilderness" is kind of special, at least the birds are. grassland is a form of ecological successional phase from the newly reclaimed land. and spore no grassland. so it may be something worthwhile to keep? (spre like to have alot of things from various parts of the world what heh)
Actually it is very prone to fire; oh yah thanks for mentioning that! fire is natural in grassland and happens quite often and some grassland plants rely on fires in reproduction, oops. this brings to question whether a grassland kind of resort is possible, cos cant possibly burn the place down once in a while.
yah i tink damn hard to wrestle the place out of original development plans. hopefully main argument is:
residential development can still go on but not at punggol end spot, leave it for a mix of tourists and locals, for memory's sake, for people's yearning for natural, open spaces, for a peek into the grassland environment (and import chipmunks in? j/k heh). the small scale tourist facilities can act as some sort of income. and jetty can be a minihub for malaysian tourists and to changi, to ubin, to coney island.
