 The term "range extension" to me means that someone has found a naturally
occurring, long standing population outside of the area where we already
knew they lived. The "range" of many species is greater than what we know at
any point in time only because we haven't discovered the true limits to that
range.

An "introduction", by definition, is not a range extension. Pete K.
