Subject: cataloging question -- noting presence of green plate on usgs topos

Hello,
I have a question that I've been curious about for a while and has recently come up again in a project I'm working on. Some USGS topos have a green layer (presumably indicating forest cover?) -- often this green plate is the only feature different from an identical map (same dates, etc.). I was wondering if anyone has noted this "green plate" in cataloging individual sheets, and if so, which field and what language you used to describe it.
Thanks in advance!
-Susan
