A water fern called Azolla, originally from America has been spreading in the British Isles in recent years and has established itself in the pond at Beckenham Place Park. It is spread by wildfowl and spore dispersal and can quickly take over a pond, swamping the native vegetation and wildlife. It can develop a floating mat 30cm thick, which shades the sunlight from the water and chokes the pond. To control this invasive weed, weevils have been introduced into the pond that eat the Azolla. This should keep it under control and prevent it from taking over the pond. This is a safe natural way to control the weed without using harsh chemicals.
