The word does conjure up trees (8)
I believe the answer is:
redwoods
'trees' is the definition.
(type of tree)
'the word does conjure up' is the wordplay.
'conjure up' indicates an anagram (I've seen 'conjuring up' mean this).
'word'+'does'='worddoes'
'worddoes' with letters rearranged gives 'REDWOODS'.
(Other definitions for redwoods that I've seen before include "Giant trees" , "Tall sequoia trees" .)
