I think it's both those answers, burra!
The love of trees wasn't the only reason, there has been much inconvenience between the elves and the dwarves. The destruction of Doriath is one of the greater ones. Also the 'too deep delving in moria' was one, I believe. For afterwards the elves had to leave Eregion. Nevertheless the relationship seems to improve after the War of the Ring and Bilbo's adventure...
- Gimli is let into Lothlorien, he is the first to enter it after the coming of the Balrog in moria.
- The relationship between Legolas and Gimli.
- Dain Ironfoot who established peace with both the men of Dale and the Elves of Mirkwood.

So it seems that many relationships that were forgotten are returning again at last. And all this because of the finding of the Ring by Bilbo.
