Another notable achievement of the ‘Restoration of Freshwater Biodiversity in Lake Dianchi’ project
(see previous entries--part 1
and part 2
) was the discovery and action taken against a number of invasive alien species which had not been recorded from the lake before the surveys initiated by the project. These include the Golden Apple Snail
, Louisiana Crayfish, Red-eared Slider
(the turtle or terrapin commonly found in pet shops the world over), and Muskrat. Their introduction to the area, as with many alien invasives, “seemed a good idea at the time” but they all have – or likely will have – serious negative economic and ecological impacts. The Golden Apple Snail has a predilection for young rice plants, the Louisiana Crayfish burrows into bunds, and the Red-eared Slider predates on fish.
