I was delighted to find a few native plants amongst all those willows. This is a very healthy looking harakeke (Phormium tenax). In fact I didn't see any holes in it at all - no moths - perfect for weaving.
Last but not least - spot the piwakawaka (fantail). I saw several of these. In fact, the riverside resounded with bird songs - thrush, waxeyes, goldfinches - you name it, it's at the river.
