Wild snake caught on film for first time in north Wales
An imported snake species believed to be breeding in the wild in north Wales has
been caught on film for the first time.
The snake - the Aesculapian Rat Snake
(Elaphe longissima) - can be seen on this week's Iolo's Welsh Safari (Wednesday 17
May 2006, BBC ONE Wales, 7.00pm).
The Aesculapian Rat Snake arrived in Conwy during the mid-Sixties when the founder
of the Welsh Mountain Zoo, Robert Jackson, imported reptiles from Italy.

The first indication of their presence were baby snakes found in the zoo grounds
in the early Seventies which were first thought to be grass snakes due to the

Over the next
30 years occasional adults and babies were observed at the zoo in Colwyn Bay,
only very rarely being found outside the grounds.
The snakes have focussed on
the zoo grounds and not spread.
The population of snakes has been the subject of a study by Bangor University
students since 2004, which is co-ordinated by Dr Wolfgang Wuster.
Zoological Director Nick Jackson said: "The Aesculapian snake is a harmless, non-venomous species which feeds mainly on rodents.
"They have never proved to be a
problem in the local area, and some see their presence as beneficial due to a
decrease in the number of rodent pests."
BBC Wales presenter Iolo Williams explained: "There had been rumours for a long
time that the species had escaped from the zoo and I thought it would be lovely
to get it on film for the first time.
"We were lucky enough to have two experts
on hand - BBC Wales snake expert Rhys Jones and Peter Litherland, a keeper at

outside the zoo as well, no two ways about it. But there's nothing for people to
