Forest areas can be easily traced from low resolution landsat imagery. It is thus possible to locate 100% of forest areas with the available satellite imagery.

NRSC LULC

The National Remote Sensing Center has released the Landuse/Lancover data for India at a scale of 1:1 million into the public domain. The dataset is available as a WMS server which can be loaded into [JOSM]

Tagging

Tag wooded areas with natural=wood, natural=scrub or the appropriate natural=* tag. If you are sure that the are is a reserve or protected forest use landuse=forest.

For protected areas like national parks, wildlife sanctuaries and reserve forest boundaries use boundary=protected_area + protect_class=*

Note: Agricultural areas may also look deceptively similar to wooded areas in low res imagery, however if you look closely you can see noisy patterns showing human activity.
