It looks like you may have modified some of your files, and the pattern of fields no longer matches where the game is being directed to plant trees.
There is nothing in the AnKor programming code that could modify or create new tree spawns in the game.
As far as the sparkle in the trees there is a new rendering function to allow transparency in the space between the leaves. To minimize the effect set
AlphaToCoverage=0 in the d3d8.ini file. If you already have it set that way, then it may be the transparency anti-aliasing setting on your video card that is creating it.
