I ask P.O. about these forest giraffes (6)

I believe the answer is:

okapis

I'm a little stuck... Click here to teach me more about this clue!

'giraffes' is the definition.
(okapi is a kind of giraffe)

'i ask p o about' is the wordplay.
'about' indicates an anagram.
'i'+'ask'+'p'+'o'='iaskpo'
'iaskpo' is an anagram of 'OKAPIS'.

'these forest' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for okapis that I've seen before include "African animals related to the giraffe" , "Ok, Pa is wrong about the giraffe-type animals" , "Relatives of the giraffe" , "They're like giraffes only smaller" , "They're similar to the giraffes but smaller" .)

I've seen this clue in the Sydney Morning Herald.
