Food on land tiles is harvested as Grain; on water tiles, as Fish. All forest tiles may be cleared by a Pioneer (using the plow action) to turn them into a treeless terrain type:

Terrain Converts to
Boreal forest Tundra
Broadleaf forest Prairie
Conifer forest Grassland
Mixed forest Plains
Rain forest Swamp
Scrub forest Desert
Tropical forest Savannah
Wetland forest Marsh

The change is permanent and any forest bonus will be deleted. As a side effect, clearance produces some lumber in the nearest colony.
