The menace of Long Valley

The spread of mile-a-minute weed is threatening wildlife and covering swathes of farmland - but officials claim they are powerless to act

The highly invasive plant Mikania micrantha is smothering the ecologically important Long Valley and threatening bird life because the government lacks the power to eradicate the weed from private property.

Invasion of species should be taken seriously, say ecologists

The invasion of exotic plants or animal species must be addressed seriously by the government following the discovery of suspected red fire ants in a wetland park, experts say.

Apart from the ants, they say there are possibly a dozen similar invaders in Hong Kong.

First person

Cheung Kwok-wai, 44, is a senior country parks officer with the Agriculture, Fisheries and Conservation Department.

Plan for fighting weed menace hits hurdle

A plan to clear an exotic South American plant - which is engulfing Hong Kong's indigenous vegetation - by using a weed killer has been blocked amid fears it could do more harm than good.

Conservationists say the Mikania micrantha plant - nicknamed 'mile-a-minute' because of the speed it spreads - kills trees and plants by climbing them and blocking out sunlight.

Science joins fight to end spread of creepy green killer

ACROSS the New Territories spreads a vile green vegetal cancer.

It clings to the border barbed wire fence, to the frustration of police officers who endlessly hack it back with knives and clippers.

It climbs across the skeletons of dumped cars in the vehicle graveyards that speckle the Yuen Long plain.

Visitors that turn into natural killers

DID you know that the introduction by man of animals and plants into new areas can be lethal? Animals and plants living on islands are especially at risk since they have not developed any protective mechanisms against intruders.
