I have a problem with fir trees 'growing' all over the place near the airport perimeter.

Frankly I am uncertain who to address with this issue, as I am not sure if those fir trees come with fly tampa libraries or if they are FTX HD trees.
Whats weird about it is they only show up close to the airport. Did not find any of them going a little farther from the airport.
Any suggestion on this matter other than call 0800-LUMBERJACK? I am experiencing this with FSX gold edition.
