Sitting here with snow on the ground this is very pleasant - it's definitely summertime in THIS forest. The opening is pastoral, with birds twittering amidst a chord-structure that indeed suggests trees, well-established, tall and straight, probably decicuous, sunlight filtering through the canopy...
It will be necessary to be careful about volume if this is to be used during a game - at my normal listening level it would intrude too much and be a distraction, although played more quietly it can be hard to distinguish the 'sounds of nature' - birdsong and even the odd frog croak - which take this work beyond a pleasant piece of music to a distinctly outdoors forest scene-setter.
One great advantage is that is is wholly-novel music, too often one gets distracted by hearing something you know, and end up thinking about the song rather than the game.
If you like background music, this could - played quietly! - provide a good background to peaceful meanderings through woodland. Perhaps lulling the players into the feeling that everything here is friendly... but is it? You'd need to stop the music if you decide something overtly hostile has arrived, though.
