Hi Mike D.,
I'm not sure about job specifics, but I do know Poland doesn't lack interest in environmental conservation. There are 23 protected national parks in Poland (8 of which are on the UNESCO list of World Biosphere Reserves) with many endangered or unique species of flora/fauna. For more info just check out some web-sites (even general tourist ones would be a great place to start getting an idea of the possibilities open to you), like this one for instance:

As for the quiet life, Poland can certainly offer you that, the country-side is beautiful and varied with many smaller towns, ranging from tiny farm hamlets to small villages to larger towns - cities are usually just a few miles away, in case you need them. It's really just a matter of doing a bit of research into what exactly tickles your fancy - rolling plains, forests, mountains, lakes - and then seeing what towns and villages occupy a particular region (taking into account places of employment of course).
Sorry I couldn't be more specific, I guess I just wanted to say 'good on you' and hope you follow your dreams - the details usually iron themselves out along the way
