The Wrybill is a threatenedplover endemic to New Zealandand unique in havinga bill curvedto the right.It is specializedfor breedingon bareshingle in thebraided riverbeds of Canterburyand Otago in the SouthIsland. After breeding,almost the entirepopulation migrates north and wintersin the harboursaround Auckland. The speciesis classifiedas Vulnerable. Based on countsof winteringflocks, the population currently appears to number4,500-5,000 individuals.However, countingproblems mean that trendsare difficult to determine. The mainthreats to theWrybill arebelieved to be predationon thebreeding grounds, degradation of breeding habitat,and floodingof nests.In a recentstudy in the MackenzieBasin, predation by introducedmammals (mainly stoats,cats and possibly ferrets) had a substantialimpact on Wrybill survivaland productivity. Prey- switchingby predatorsfollowing the introductionof rabbithaemorrhagic disease in 1997 probablyincreased predationrates on breedingwaders. A recentstudy of stoatsin the TasmanRiver showedthat 11% of stoat densexamined contained Wrybill remains.Breeding habitat is beinglost in somerivers and degraded in oth- ers,mainly by waterabstraction and flow manipulation,invasion of weeds,and human recreational use. Flood- ing causessome loss of nestsbut is alsobeneficial, keeping nesting areas weed-free. The breedingrange of the speciesappears to be contractingand fragmenting, with the bulk of the popula- tion now breedingin three large catchments.

The results of these investigations have been reported in various reports, theses, Department of Conservation publications, and scientific papers. Results of all significant research have been published, can be found through literature searches, and are widely available. Internal reports that do not warrant publication are held at the Twizel Te Manahuna Area Office and at the main Department of Conservation library in Wellington. All unpublished Project River Recovery reports produced since 1998 have been assigned report numbers. In addition to reports on original research, Project River Recovery has produced magazine articles and newspaper feature articles, various annual reports, progress reports, discussion documents, and plans. It has also commissioned some reports from consultants. This bibliography updates the bibliography compiled in 2000 (Sanders 2000) and lists all reports, theses, diplomas, Department of Conservation publications, and scientific papers that were produced or supported by Project River Recovery between 1991 and July 2007.

    Project River Recovery after 25 years BRaid, 31 May 2016 Aalbert Rebergen What has changed? Sr. Ranger PRR Doc Twizel PRR’s work area, the Upper Waitakai Catchment PRR Strategic Plans: ? 1991-1998 Brown/Sanders 1998-2005 Woolmore/Sanders 2005-2012 Rebergen/Woolmore 2012-2019 PRR in the early days: Run as an ‘independent’ project, with a PRR Manager, PRR Scientist and (up to four seasonal) staff. Bird focus. Focus on research, survey & monitoring & ambitious large scale weed projects, often in compromised areas (Tekapo delta, lower Ahuriri). All research published in peer reviewed journals. Strong participation from universities, students doing projects every year. Some interpretation/education: media, signs, brochures. Now…. Fully integrated in DOC Twizel, but with its own budget, currently approx. $525K/year (indexed and any surplus can be carried over). No PRR Manager, or scientist. Twizel Operations Manager is responsible for PRR. Strong focus on river habitat management. Current PRR staffing is a D-band Senior ranger, responsible for the day to day management of the project, a C-band ranger and .5 FTE B-band ranger (weeds). No Seasonal staff. Technical expertise is provided by DOC scientists (and Braided River Specialist Group) based in Christchurch. Most weed control work is carried out by an experienced local weed contracting firm. More about our current work priorities later. What hasn’t changed? Weeds, especially Russell lupin, are an ongoing serious threat to braided rivers. We focus on those rivers that can be managed with current methods within our budget. High altitude rivers are our priority. We no longer target badly weed infested lower altitude (parts of) rivers, e.g.

If you are fishing near the Ōhau power stations, large skip bins are provided by Meridian for your use. Do not leave fish frames and guts in the margins of the water, wrap them in paper and a plastic bag and dispose of them in the skip bins. Please also be careful not to snag your line in the power station intakes, fishing nylon is causing R Adams blockages to the intake screens, which then causes issues for A salmon caught near the farm pens on the Tekapo Canal hydro generation.
