Yes, the stories are very much centred on those trying to despoil and those trying to defend nature and their world. Which is very similar to LOTR, with the industrialised Sauron and Saruman and their creation of orcs, and the other races (especially the elves) who are much more in harmony with Middle-earth. The 'Sunbane' which appears in the 'Second Chronicies' is an astonishingly creative transformation of nature into a weapon to be used against the inhabitants of 'the Land'.
Whereas Tolkien's world is filled with hope, love and a real feel-good factor, Donaldson's is full of hate, despair and even when (sometimes) things work out right, you never feel (or at least I didn't) any feeling of satisfaction. The protagonists such as Hile Troy, Linden Avery and Covenant himself are (at best) dislikable characters, and a world away from the likes of Aragorn, Boromir, Gandalf and Sam. Perhaps Donaldson's characters are more true to life than Tolkien's heroes, but it doesn't make them necessarily 'better'.
