The wood elf theme makes it sound like a ranger, especially with the bow, however wardens often use spears, shields, and javelins. A highlamder however doesn't really seem to fit, as that would imply mountains or hills now a forest protector. You could go with something from warhammer fantasy and call it the glade guardian. In warhammer fantasy wood elf units tend to have both bows or spears, and glade riders were horseback riders using javelins, glade guard used bows, eternal guard used double blades staves, then they had war dancers that used spears or dual wielded swords. So a glade guardian would be more like a traditional protector type, however with w wood elf feel, it would be a protector of the forest, using bow and spear, with a combination of healing magic.
So I suggest going with glade guardian.
