Standing up, tree collapsed (6)
I believe the answer is:
repute
'standing' is the definition.
(I've seen this before)
'up tree collapsed' is the wordplay.
'collapsed' is an anagram indicator.
'up'+'tree'='uptree'
'uptree' anagrammed gives 'REPUTE'.
(Other definitions for repute that I've seen before include "Known character, standing" , "Fame, renown" , "Distinction" , "Public estimation" , "What is generally believed about a person" .)
