text: There are a lot of detailed pieces of landcover on the grounds here. They seem to come from an import by user brentengust, and could be improved: some divisions seem arbitrary, the pieces should be merged. 
    
  Also, there are a lot of tags "landcover=Lawn" or "landcover=Garden". Values in OSM are supposed to be lowercase. 
    
  Additionally, I believe "landcover=grass" would fit better in many cases, maybe with leisure=garden. See the proposal for landcover and its discussion page:  https://wiki.openstreetmap.org/wiki/Proposed_features/landcover
