Has anyone any good Books or some sort of Compendiums about Druids their motivations and such?
Preferably close to DnD/Pathfinder.If it goes a little away from the treehugger theme that would be especially interesting.

Sleet, are you referring to actual real-world Druids (the celtic ones)? Or general wilderness oriented spellcasters in myth, legend and literature?
No, I don't have any good books other than books about Merlin that might be instructive (The Crystal Caves and The Hollow Hills come to mind).
However, some commentary might be helpful.
"Treehugger" is my least favorite druid trope. I can accept it as being a legitimate druid type but I find it to be utterly derivative and downright silly.
There are some basic druid concepts that I like:
1. The guardian: This is a druid who has adopted some wildland or some portion of a wildland as their own domain and they protect it from harm. This is primarily a spellcasting druid who generally travels and works in humanoid shape. They befriend, assist and at times educate the local animals and tend to the local plants. They typically have an animal companion that travels and lives with them. They usually live in the midst of the wilderness they are protecting but in such a way that a casual passer by probably would not even recognize the druid's home as a place of residence. The wildland would typically include some populations of magical creatures such as dryads or unicorns.
2. The avenger: This is a druid who is out for vengeance. It might be a druid that was once a guardian, but whose wildlands were ravaged or destroyed by outside forces. Avengers are frequently in beast shape, especially excessively large beasts that are particularly ferocious. They typically have a grudge and might even attack certain creatures without cause or warning, just because they are similar to the creatures that performed whatever atrocidies the avenger is avenging. Avengers sometimes travel with packs of angry animals, so an encounter might be against the avenging druid and a pack of grizzly bears.
3. The nurturer: These druids are all about spreading the joy of life. They are the type of druid most likely to cooperate with a village by helping them farm or raise livestock. They recognize that civilization and wilderness are both valid examples of the cycle of life. They typically view humanoid species as a particularly vexing form of life, but a valid one nonetheless. Nurturers sometimes have no home and wander from place to place healing sick areas of the world and nurturing the new growth they find. They like spells like "control weather" or spells which increase a crop's yield.
4. The intelli-centric: These druids have decided that all life is important, but that some life is more important than other life. They promote the growth of civilization as an end in itself. These are the druids that typically become "urban druids". They view intelligence as the end result of the survival of the fittest and will do what they can to ensure that intelligence is protected. They view wilderness focused druids as naive and ignorant. To cut down a forest to build a wall around a city is perfectly acceptable to the intelli-centric druid.
Just some examples off the top of my head.
