Does It Add Up?

More than 24000 Adders, Grass snakes, Common lizards and Slow worms have been reportedly transported by van from a site in Essex where the £1.5bn London Gateway Container Port is being built to a now 'full' reserve in Wiltshire (http://www.guardian.co.uk/environment/2011/mar/21/essex-reptiles-wiltshire-homes?INTCMP=SRCH ). This actually seems a very odd thing to do as the introductions are very likely to alter the dynamics of the local Wiltshire populations of the reptiles and their prey.
