This is the bonus experimental dense forests by alpilotx (Andras Fabian), downloaded from http://www.alpilotx.net/downloads/x-plane-10-hd-mesh-scenery-v3/ and combined with XP11 elements to a library with Andras' and Laminar Research permission.
A few things to consider with this experimental(!), dense forest replacement: It will probably make your FPS worse! Depending on your 3D card, this effect might be more or less strong.
PLEASE DON’T REDISTRIBUTE this forest replacement pack! Its experimental, and should remain as such. If you want to donate Andras work, on his website you'll find a donate button, click http://www.alpilotx.net/
Just copy the folder "Dense_Forests_Library" of the archive to your custom scenery folder.
