Grass snake expansion in southern Netherlands

This video is called Britain in COLD BLOOD – The Grass Snake (Natrix natrix).

From Reptielen-Magazine in the Netherlands:

In late August this year, in a hotbed in a small nature reserve in Limburg, the first grass snakes of this southern Dutch province were born! Ever since 2005, grass snakes have been observed regularly along the border river the Wurm. However, so far there had not been a stable population, including breeding, yet.
