Finger-width holes on tidal mudflats are the handiwork of the tunnelling mud crab (Helice crassa), and you might see these tiny grey-green crabs scuttling back into their tunnels if you pass too closely by these nervous creatures. They have reason to be nervous, they’re food for wading birds, gulls, kingfishers, fish… it’s a long list. The tunnels serve as protection from predators and also aid in stopping the crabs from drying out. During the day when the tide is out, they scurry around eating tiny things that live in the mud. At night and when the tide is in, the safest place is in a tunnel, which they might block up to keep predators out. Thinking of digging into a tunnel to go after a crab that’s disappeared into it? Probably not a great idea as the tunnels can be complex, with multiple entrances; the crab is probably long gone. If cornered, they’ll assume a defensive posture, as in this photo. (No tunnelling mud crabs were harmed in the taking of this photo. Except perhaps psychologically.)

The walk up to Wainui Falls runs alongside the Wainui River, which flows through granite bedrock. While lots of pictures get taken at the falls upstream, there’s not so many taken of spots downstream. There are good access points down to the riverbed along the way, ideal swimming spots for a hot day. The forest in the background is full of nikau palms, ferns and rata, which is pretty typical of the native bush in the Abel Tasman.

In 1900, the New Zealand government ordered the Janie Seddon for use as a mine laying vessel to defend against the Russians. Built in Scotland, she was delivered in 1902 and served in the First World War. Her role was limited, though, as she carried very little coal and so had a short range. In 1936, Talley’s purchased the Janie Seddon, their first fishing vessel, which didn’t work out too well, again due to her short range. During World War II, she was requisitioned back to the navy, and after the war, she was sold to the Motueka Trawling Company. By 1947, she was being operated by Talley’s once again, which only lasted for three years. In 1953, she sank at her mooring off the Motueka sandspit, possibly after coming to rest on her own anchor as the tide went out. Today the wreck of the Janie Seddon lies on the Motueka beach just off the old Motueka Quay. There’s been talk of removing the wreck from the foreshore due to safety and environmental concerns. She continues to deteriorate: Compare the state of her above, taken early in 2018, to the photo from the 2014 Stuff.co.nz article.

This photo taken from the outskirts of Motueka shows the late day sun picking out the foothills of the Arthur/Wharepapa Range, which dominates the skyline west of Motueka. Great spotted kiwi/roroa (Apteryx haastii) live in those mountains, due to the efforts of the Department of Conservation and the Friends of Flora. Predator control has been undertaken for nearly two decades in the Flora Stream area, and the first roroa were reintroduced in 2010. The first chick was born in 2012, and subsequent relocations through to 2016 have established what will, hopefully, be a sustainable population. The Friends of Flora Facebook page has a cool video of two kiwis calling to each other, one from the entrance to their nest burrow and the other from the surrounding bush. Sadly, it will be some decades before kiwi are common in the mountains.

What looks like dead wood that’s been spray painted is actually caused by a fungus called Chlorociboria. The blue-green stain is a metabolite called xylindein. Historically, wood stained green by Chlorociboria has been valued for inlaid woodwork. This American Scientist article on The Fine Art of Decay talks about woodworking with fungal pigments.

Near the end of the Harwoods Hole track, the Gorge Creek track branches off and snakes up the hillside. The top of the hill is covered in sharp, fluted marble and you can see out over Gorge Creek and the Takaka River valley. Gorge Creek originates from the underground river that flows through the Starlight Cave system.

About 20 km from Takaka along the road that goes to Totaranui, the walk up to Wainui Falls is just half an hour and well worth the stop. Because the waterfall is both spectacular and close to the road, it’s a popular walk with visitors to the region. Start or finish with a drinks and snacks at the coffee caravan at the start of the track.

This is Alphonso and he’s the loneliest duck in the world. He’s a Mandarin duck (Aix galericulata) and he turned up at Lake Rotoiti in the Nelson Lakes National Park in the spring of 2014, origins unknown. Mandarin ducks aren’t native to New Zealand, there isn’t an introduced population and it’s unlikely he found his way from somewhere-not-New-Zealand to Rotoiti under his own steam, which means he’s probably an escapee from a private breeder. This photo shows Alphonso while he’s moulting into his eclipse plumage, so he’s looking pretty scruffy. Every spring, he moults into spectacular breeding plumage, only to be rebuffed by the local mallards.

Moutere vines

The Moutere Hills lie west of Mapua and Ruby Bay and the Moutere Valley is one of the sunniest parts of New Zealand. The area has been popular for apple growing, forestry and, in recent decades, grape growing. These grape vines are at Neudorf Vineyard in the Upper Moutere Valley.

Harwoods Hole near Takaka is New Zealand’s deepest vertical shaft. It falls about 183 metres and connects to the Starlight Cave system. An underground river flows through the cave system and then out into Gorge Creek and the Takaka River.
