In late November Steve Playle did a trap run at Boggy Pond and Wairio. The count was 1 ferret, 1 rat and 10 hedgehogs.
“The ferret was a big bugger and was caught along the stop bank between Mathews and Boggy. This took the total predator count to 23 ferrets, 1 stoat, 2 weasels, 4 cats, 5 rats and 14 hedgehogs.” said Steve.
Rampant growth of grass and weeds along with warm weather meant extra time cleaning around trap sites. Steve also put out another seven DoC250 traps on the Wairio Restoration Block along with two more timms traps along a pine belt where cats have been seen.
Stock tends to interfere with the traps in the Wairio Restoration Block. “We have to live with that unfortunately,” said Steve.
Mice also play havoc with baits with most traps stripped of meat if they have not had a kill in them. Steve said he knows it’s mostly mice because the DoC traps have mouse droppings in them. He has seen mice in the timms traps too. “With only one ferret for this check it could mean their numbers and getting down or maybe they are feasting on mice or even frogs as the place is alive with them at the moment,” said Steve.
Steve has seen and heard bitterns and another was heard at Mathews pond.
Trapping is ongoing.
Maybe - but not just yet
The Ruahine Whio Protection Trust (RWPT) is a registered charity formed in late 2014 and functions though the efforts of a small group enthusiastically lead by chairwoman Janet Wilson. Its purpose is to raise funds to help protect and raise the number of Whio in the Ruahines and surrounds.
Janet has tramped for years in the Ruahines as a member of the Palmerston North Tramping and Mountaineering Club (PNTMC), and whio are often spotted on the river. Although being a protector of whio was not Janet’s original ambition, she took the opportunity to become a protector of the whio living and trying to survive in the area. Janet took over the running of the Oroua Valley Blue Duck Protection project from the NZDA (Manawatu Branch) in 2011. This expanded in to the Pohangina River in 2012.
“Life hasn’t been the same since,” said Janet. Trapping began in the Ruahines in 2007. Several groups now look after approx 1800 predator traps, predominantly DOC 200’s. These range from the Aorangi–Awarua Trust’s lands in the North to the Pohangina River in the South. In 2015 a Ruahine Whio Management Plan was developed by these groups with support from DOC, and along with the RWPT, they now make up what is known as the Ruahine Whio Protectors Collective.
Janet still coordinates the Oroua and Pohangina projects. Between July 2015 and June 2016, 110 stoats and weasels were caught, as well as 450 rats. She has a good team of willing volunteers but is always keen to hear from experienced trampers and hunters who might like to help out the whio. For many a tramp in the bush is no longer just a Sunday outing. It has become an ongoing war against the stoats, weasels, rats, and any other likely whio enemy.
Whio are the most endangered bird in the Manawatu and Janet is keen to raise the profile of our $10 duck locally. Janet said the Oroua and Pohangina rivers have the most southern population in the North Island. There are no known whio in the in the Tararua and Rimutaka ranges.
I run a yearly total as at November 30 each year as part of the excellent initiative of the ‘Swamp Comp’.
For the year ending November 2015 from 6 DoC 200 traps placed around the margins of my wetlands, the list was 11 Weasels, 1 Stoat, 2 Ferrets, 33 Hedgehogs and 7 Rats.
So for the 2016 year where 2 more traps were added in February, with the total of 4 Weasels, and Stoats, 1 Ferret, 12 Hedgehogs and 16 Rats it seemed that we were making a great inroad.
It may seem now that the inroad thought was rather premature, with just under 5 months of the current year run, the total sits at 20 Weasels, 3 Stoats, 7 Hedgehogs and 9 Rats.
The other point is that I have one trap [See photo, note there is an egg, I also bait with the juice from Sardines in spring-water] that is generally located in a central position, with the other traps generally outside of it.
That trap known as Cabbage Tree, has accounted for 15 of the Weasels, 2 Stoats, and 4 Rats, the last one as of April 25.
Possibly the high number may be attributed to the very wet Summer-Autumn where the wetland core which is generally only damp under the Harakeke, Coprosma and Toe Toe associations is this year very wet, so perhaps there is a concentration moving around the dryer margins, however that is only a possible theory as equally the food abundance could be another contributing factor.
