Makarora bat survey

We found some endemic long tailed bats last night. "We" being some local DOC staff and myself, a happy and oft present volunteer.

Not in the bush as expected, but where the road looked out on braided river bed. These little critters prolific in many parts of our country many years ago maybe among the oldest mammals living in New Zealand.

A daylight shot I made on a DOC braided river bed bird survey a couple of years back. The view is very close to where myself and Ute found our bats...

They're about as big as a mouse and capable of 60 Km/hr flight and feed over vast areas [the rest of the time they roost in trees not caves].

The survey started on dusk in the sleeply nearby tourist stop, Makarora, on the highway to Haast...

In groups of two, we each we walked 5 Km split into 1 Km transects on the Haast highway, and used little black boxes that pick up the bat's sonar - the noise being like a static version of a mouse wearing shoes and running on a tin roof. This is the first confirmation of their existence since the the early 1900s. The gear I assume was borrowed from Fiordland National Park where they've not only found colonies in the Eglington valley, but captured some and fitted them out with transponders and tracked them.

It was too dark on our survey to make photos without a tripod, and besides time is of the essence, but this shot of us on a bird survey shows how we dress and also my good friend Stu, who thoughtfully includes me on these fascinating surveys...

It was really exciting, and the walking was like luxury tramping as there were few cars and being on a road there was little worry with footing, then walking out of the totally dark bush and onto Cameron Flat with it's views of Mt Brewster, into the near full [moon] moonlight, was extraordinary.

Another exciting find some years back - one I was able to capture with the camera: a nesting Banded Dotterel [Tuturiwhatu] doing a "I'm wounded" dance, to lure me away from the nest...

Many species compete for food on our unique and harsh braided river beds. Here local farmer and friend Mike crosses the Makarora. The truck incidentally sans floor mats and bungs so it'll fill with water and not float!...

More Clutha River wanderings

When the sun looked like dissipating the inversion cloud this morning I packed a lunch and Dougal and I headed off for a walk, heading yet again on further personal exploration of the Clutha River near home.

Looking west towards Black Peak and Treble Cone, while we walked in hope of the cloud letting the sun shine on us...

Further downstream past Reko's Point, and looking south to the end of the Pisa and Criffel Ranges...

It had been bothering me - just who was Reko? I knew the name and then I recalled he was the guide of Surveyor J.T. Thomson:

He persuaded Reko of Tuturau to guide him from Otago to Canterbury by an inland route. In September 1853, he, Reko and another Maori companion set off up the Mataura and the Nokomai valleys and over the hills to the Nevis and Kawarau valleys. They crossed the Kawarau River on the natural rock bridge and went downriver to the flats above Cromwell. They made their way to Wanaka and Hawea, before Chalmers, who was exhausted, gave up any idea of going further, and the group returned by raft down the Clutha River (McClymont 1959: 70). More on the New Zealand Dept of Conservation website


Thomson was an accomplished artist and I found a picture he made of a spooky crossing of the Mataura River with Reko on the teara.govt.nz web site

As we walked I asked Dougal to consider that there are people that want to dam this amazing river and drown the landscape. I think he had trouble grasping this and I guess age 16 has not given him enough time yet to ponder the losses I've seen...

I've paddled this river in a past life, camping on the way and that was adventure enough. It must have been something else for Reko, Thomson and Chalmers to build their own raft and head off, bobbing along at speed as the craft became water-logged, and not have much of a clue as to what lay ahead. On many stretches of the river it's really hard to get into the edge as boil ups keeping pushing upwards denying access...

Locally so many of us have concerns about ill conceived ideas to mess up this planet, rivers and all that we live on - and everyone is a local relevant to where they live, so in a wider and more global context take some time please to check out the movie "home"on youtube by Yann Arthus-Bertrand. It has beautiful imagery of our mother earth and commentary of our evolution into where we have brought our planet to today. It's free on the web for a few more days [and is a 1.4 Gb download so it is not a short one].

Last week I found some stellar GPS software for my iPhone for about $NZ7 so we tried it out alongside my old GPS and found it remarkably good - nothing like a good day to play with new toys!

Dougal thought it was funny that the map is courtesy of the US Navy - us being inland and all that. This screen shot is of Reko's Point - I wonder if this is where they built the raft, as it's too close to Lake Wanaka to be the first night's camping spot. The green "init" maker is a way-point the phone generates each time it's turned on...

And this week's head's up is to cousin Deirdre's Tininn Lodge site where she has posted photos of her grand daughter Aleisha doing some part time modeling.
