Hi,
There should be no need to edit 'Pines Flora & Fauna Reserve' as that comes from government data. Assumes that no one has altered it from when it was first entered. Try to leave these government entered data alone.

I have tried to detail the trees in this area using bing. As it is a reserve the trees would not be used for produce thus not a 'landuse=forest'. When looking a 'green' area does not always mean 'trees' - could be scrub, heath etc.
