I think the common name for "rational concept of environmentalism" is probably conservationism.

Don't know of any good conservative conservationist (boy is that a mouhtful) groups though.

Try just about any hunting or 4WD advocacy group.

You are correct, actually there are a lot of conservative conservation groups, most deal with hunting / fishing issues.
