I think 'exterminate' is a little harsh, Dave. The prime Dorset habitat where L.agilis has coincidentally dissapeared since the introduction of muralis, has caused concern for various people round here that want any of the few remaining areas suited to the future and safeguard of agilis's survival, to stay that way. As you say, this topic was done to death last year, and i think most people got to aire their views on the matter then. However, to answer your other question, i don't personally have a problem if an introduced species resides somewhere where it is not likely to compete or threaten in any way a native species, especially a species that is known to fall under the title 'nationally endangered fauna/flora'.

hi Davew I cant see why you have a problem with the reintroduction of naturals as many of us think  this is the best way  we can preserve our declining species that have lost so much habitat in this country over the years .keith

I personally love seeing Wall lizards in the UK, they add that little extra bit of diversity and  interest in parts of the South.

I am strongly against their introduction in places where they may impact upon our native ecosystem. We don't know for certain that they have a negative influence on native species, but not knowing is no excuse for introducing them.

They are also full of alien pathogens, and we don't know how such organisms will affect native Sand lizards...we really don't want a repeat of the Red Squirrel issue!

In summary...no problems where they occupy an isolated ecological niche...but introduction where they may affect native species is downright irresponsible!

my 2 cents.

Hi - to answer the two points;

How is exterminate harsh. People caught Wall Lizards and though supposed "nature lovers" actually killed them. Exterminate seems about right to me.

In the birding world many reintroductions have been made perhaps the most famous being the Red Kite. I can see only one reason for reintroducing an extremely abundant world species into a country where it hadn't been truly present for centuries - vanity. Somebody had the "nice " idea that wouldn't it be lovely if Red Kites were back here and with no more firm reason than that it started (and yes I've looked into it and I couldn't find a concrete reason). Waste of time and money. If a species is globablly threatened then perhaps it's worth it otherwise why bother.
