As you've noted the National Park Boundary isn't going to always be
natural=wood, so maybe keeping them in separate ways/multipolygons is
best? Regarding the coastline, does the NP boundary extend to the
coastline? Do the trees also extend that far? Normally you would get
some rock or sand between the trees and the coastline, so they
probably won't match up. It depends how much detail you want to put
into it.
