This rangers name is 'Jo'. He's checking traps with a sinker on a string, but he's not fishing!
I'm feeling a bit tired here!
We walked 11 hours to the hut to stay the night, checking traps all the way.

Jo is making sure the traps are working. If they don't go off when the weight goes on the trigger then they are not set correctly and won't catch the stoat when it goes to eat the bait.

Do you know why stoats are a problem in the Okarito sanctuary?
