Forest dwellers seeing prophet come back to Earth? (5,5)

'forest dwellers' is the definition.
(type of tree)

'prophet come back to earth?' is the wordplay.
'prophet' becomes 'seer' (both can mean someone who tells the future).
'come back' says the letters should be written in reverse.
'to' means one lot of letters go next to another (I've seen this in other clues).
'earth?' becomes 'planet' (Earth is an example).
'seer' reversed gives 'rees'.
'rees' after 'planet' is 'PLANE-TREES'.

'seeing' acts as a link.
