Dudley No.1 Canal at the Waterfront, Brierley Hill has been hit by a water fern outbreak. An army of 10,000 bugs have been released into a Dudley canal to feast on a problematic water weed. The borough's first water fern 'outbreak' has left the surface 'looking like a football pitch'. |
It’s the first time this has happened in the West Midlands, according to the Canal & River Trust.
A spokesperson for the trust said: “It grows really quickly in warm, wet weather – which is why it’s gone absolutely crazy.”
The trust said to tackle the problem - thousands of weevils have been released to eat the weed and stop it spreading further along the waterway.
It said the 2mm-long weevils will munch up the invasive water fern (Azolla filiculoides) which, if left unchecked, can cover canal surfaces with a thick weedy mat.
The weevils are said to be an effective natural means of tackling the problem as they rapidly eat up a very large mass of the water fern, and they feed exclusively on azolla - without damaging other native species.
The canal is said to be "one of the worst affected areas in England" at the moment. One passer-by thought the stretch of water, near Merry Hill shopping centre, had been 'filled in' due to it's solid-like appearance.
