"Native vegetation" means vegetation comprised of plant species, other than noxious weeds, that are indigenous to the coastal region of the Pacific Northwest and which reasonably could have been expected to naturally occur on the site. Examples include, but are not limited to, trees such as douglas fir, western hemlock, western red cedar, alder, big leaf maple and vine maple, shrubs such as willow, elderberry, salmonberry and salal, and herbaceous plants such as sword ferns, foam flower and fireweed.
