British NVC community OV6 ("Cerastium glomeratum" - "Fumaria muralis" ssp. "boraei" community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of six arable weed and track-side communities of light, less-fertile acid soils. Using only the above description and what you know about the world, "British NVC community is the biggest amongst six arable weed communities of less fertile acid soils" is definitely correct, incorrect, or inconclusive?
