Wood in shore area mentioned (5)
I believe the answer is:
beech
'wood' is the definition.
(I know that beech is a type of wood)
'shore area mentioned' is the wordplay.
'shore area' becomes 'beach' (I've seen this before).
'mentioned' indicates a 'sounds like' (homophone) clue.
'beach' is a homophone of 'BEECH'.
'in' acts as a link.
(Other definitions for beech that I've seen before include "Tree (with green or copper leaves)" , "Timber tree" , "It has branches" , "Deciduous tree with smooth grey bark" , "Tree of Fagus genus" .)
