The general term for the study of landforms and shapes is topography.
Plains: Campester is Latin for plain
Islands: Insula is Latin for island
Swamps: Palus is Latin for swamp
Mountains: Orography
Forests: Silvi-something-or-other
Some people use the word Silvics as a catch all term, but I would say that the study of forests is rather fragmented and we have Forest Ecology, Forest Genetics, Forest Pedology, and so on. Silviculture is more the study of cultivation of forests but it might be closer to the original question, I’m not sure.
On a whim, I went to the online Greek dictionary. Assuming "-logy" means "study of" (as in "biology" [s]b[/s]from bios life and logos study of) we could coin "dentrology" from "dentro," arbor, tree.
Silviculture is derived entirely from Latin, but silvology is half Latin half Greek.
Actually, there is a discipline called dendrology but refers to the study of individual trees (there is also dendrochronology, studying rings and relating them to environmental effects, e.g. fires).
I couldn’t find a word for "forest" in the online Greek dictionary, so I had to settle for "tree." I suppose the plural of tree is forest, but I don’t know how to form a plural in Greek. Maybe the ancient Greeks couldn’t see the forest for the trees?
[quote author=Stargzer link=board=what;num=1043042559;start=0#11 date=01/22/03 at 21:49:53] . . . the plural of tree is forest . . .
Oh, right. And the plural of car is traffic jam, the plural of cow is barn, and the plural of check is overdraft.
Seriously, it looks like we do need a word for the study of forests. If no-one beats me to it, I’ll research the subject a bit more over the weekend. (Too busy now scribbling for a living.)
And BTW, there’s nothing wrong with combining a Latin prefix with a Greek suffix: Orography is precisely such a construction.
From Webster’s New World Dictionary of the American Language, Second College Edition, Complete Reference Edition (1972):

Somedays it pays to check an actual hardcopy book.
