Garden Snails and large brown snail.

This warn damp morning my garden is covered in large brown garden snails which are around 25mm across. They may be Cornu aspersum.

Are these an introduced invasive species?

My childhood memory of 50-60 years ago is of a much smaller snail around 15mm max across and much more varied in colour.
What is the effect of these big boys on the smaller ones and further down the line on the song thrush.
Again my childhood memory is of the thrush smashing the smaller snails on a favourite rock with a pile of broken shells around it.
