Takahē in the newsTakahē population 100 breeding pairs strongOctober 1 marks the start of the takahē calendar year and this year's count has the total population at 347 birds (up from 306 this time last year). The Takahē Recovery Programme, along with it's partners Ngāi Tahu and Fulton Hogan, are also celebrating surpassing 100 breeding pairs across the population. This is a significant milestone, as the number of breeding pairs is the most accurate measure of population heath. A total population number can give false security, if there is a significant age or sex bias Read more about what this means for the recovery of takahē. Takahē to be re-introduced to Kahurangi National ParkThe most exciting news from the Takahē Recovery Programme is the planned release of 30 takahē into Gouland Downs, Kahurangi National Park. Unfortunately bad weather and the impending breeding season meant plans to conduct the translocation were put on hold in August this year. Kahurangi National Park could be the home to the first wild population of takahē outside of their Murchison Mountain refuge. Learn more here about why Gouland Downs is considered a suitable site and what it could mean for the species. Plans to complete the translocation are in place for early 2018. In the meantime, just think about how amazing the possiblity is of seeing wild takahē as you walk the Heaphy Track!! New enclosures increase breeding potentialThankfully the work at Burwood was completed in the nick of time to house the 30 Kahurangi bound birds over the summer breeding season. Jade Maguire from Ōraka-Aparima Runaka (on right) blessed the pen at the opening. Work has been completed to double the area of one of the original pens at the Burwood Takahē Centre, to now cover almost 135ha of the tussock reserve. Learn more about how the pen allows for a further 5 breeding pairs and also increases the capacity for the Programme to overwinter young birds before they are released into the wild. In August, Maungatautari Ecological Island welcomed Brodie and Puiaki into their new purpose built Coopers Pen, bringing the sanctuary's takahē population up to two breeding pairs. Both extensions were made possible through the support of Mitre 10 - the Programme's Offical Supplier. ......and new locals for Pukaha and ZealandiaPukaha Mount Bruce and the resident male takahē Natural, welcomed the arrival of FOMI, a female takahē from Mana Island in June 2017. And as T2 is living out his days in a peaceful area of Zealandia, Nio and Orbell (also ex-Mana Islanders) have taken up residence in the sanctuary's wetland. Fortunately, it appears all the pairs have found their new homes to be satisfactory, as breeding attempts for all the above birds have been reported so far this season. Fulton Hogan supporting Takahē RecoveryPassing their one year anniversary as DOC's national partner to support the Takahē Recovery Programme, Fulton Hogan staff have been getting stuck in to help the birds on the ground. Read more about Fulton Hogan's involvement, including a working bee at the Burwood Takahē Centre, building a holding pen at Tāwharanui Open Sanctuary during Conservation Week and increasing takahē awareness by showcasing the Recovery Programme in their recent sustainability display in the Christchurch airport. An awesome effort from all the teams and it's been invaluable having such compatible skill sets for the tasks at hand. Technical talkUnderstanding takahē - stoat plague dynamicsThe problem: When beech forests produce large amounts of seed it can cause a large spike in rodent and stoat numbers. Often, this ‘masting’ has devastating effects on our native wildlife. As the diagram below shows, lots of seed in one summer can result in lots of stoats in the next. Last summer the beech and tussock seeded heavily in the Murchison Mountains – home to the only wild population of takahē. Monitoring has confirmed that there have been high numbers of stoats during 2017. Management: The 50,000ha Takahē Special Protected Area of the Murchison Mountains has an extensive trapping network, which is part of DOC's Battle for Our Birds operations. In 2007, a quarter of the Murchison Mountains takahē population was lost to stoat predation. Since then, the trapping network was significantly expanded, and has been quite successful in protecting takahē through large masting events in 2012 and 2015. To help monitor predator numbers and to reduce the threat of predation, the traps are being checked and cleared frequently. Stoats are the main threat to takahē, but when rats are very abundant they ‘clog’ the traps, reducing the effectiveness of stoat control. The Takahē Recovery Team are also closely monitoring about 40 birds which are wearing transmitters. The survival (and cause of mortality) of these birds is used to predict what is happening across the whole population of about 130 individuals. Given the current high stoat numbers, we expect there to be some takahē deaths due to stoat predation. We also expect that the extensive trapping network will successfully protect most of the takahē population, and so far, it has been doing a good job. The team will continue to monitor the situation, and has plans in place if we see high levels of predation. The worst case scenario could involve the evacuation of wild birds to the safety of the Burwood Takahē Centre until the threat has subsided, but this is unlikely to be necessary.
