Darts damage, please help!!!?

I have a Dart board in my sittingroom which has a wooden floor. The floor now as small chunks gone from the wood and pricks from the darts just below the board from the darts bouncing off the wire (not me!!!). Any suggestions on how I can make it look better without having to replace the floorboards.

Thanks.
Update: Thanks for suggestions so far. I did have the intelligence to buy a mat and always had the wall protected but eh... you learn huh?!
