Birchbark (5)
I believe the answer is:
canoe
'birchbark' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for canoe that I've seen before include "Light boat propelled with paddle" , "Light boat propelled by paddle(s)" , "Boat (that can be dug out!)" , "Ocean (anag)" , "Kayak-like boat" .)
