Curlews in Crisis Workshop – New Forest Golf Estate, Tyrellspass, County Westmeath, Ireland. November 4th 2016
A guest blog by Mary Colwell who is at the forefront of campaigning and raising awareness of curlews across the Britain and Ireland. Mary initiated the Curlew in Crises workshop in Ireland, with organisational assistance from University College Dublin and BirdWatch Ireland and funding from the National Parks and Wildlife Service and the Heritage Council. Forest and Environmental Research Services (FERS Ltd.) were also party to the survey effort as contractors.
Surveys carried out over the last two years across the Republic of Ireland show that there are only around 130 pairs of breeding curlew left. In the 1980s there were 5000. That is a shocking decline for a once common and widespread bird. This iconic bird of bog, moorland and rough pasture is about to slip away from the Emerald Isle. In response to this imminent extinction a Curlews in Crisis workshop was held in County Westmeath, on November 4th and generously hosted by the New Forest Golf Estate (http://www.newforest.ie/).
100 people representing farming, government, forestry, non-governmental organisations, energy production, academia and bird watchers gathered for a day of presentations on the status of the Curlew around Ireland and to take part in workshops to devise solutions.
The morning was devoted to the presentations and all were fascinating and salutatory. The morning session was chaired by Michael Martyn, an independent ecologist. (http://michaelmartyn.ie/)
Barry O’Donaghue from the National parks and Wildlife Service (https://www.npws.ie/), who commissioned the surveys, showed where the remaining birds are located. The surveys were carried out over two years and the dots represent where nests were found; the 2015 results are shown in yellow and 2016 in red. These surveys highlighted that the bogs of central Ireland, unimproved meadows and rough, wet pasture are the remaining strongholds of curlews. An area of seasonally flooded meadows along the Shannon, called the Shannon Callows, was not included and is thought to contain around 5 pairs. This area will be surveyed in 2017. Both surveys were carried out by BirdWatch surveyors and volunteers.

It was found that 79% of the birds were nesting on peatlands and bogs and 29% on rushy pasture and wet grassland.
Anita Donaghy from BirdWatch Ireland (http://www.birdwatchireland.ie/) identified the main threats as peat cutting, improvement and drainage of rough wet areas into pasture, predation, specifically by foxes and hooded crows, and the spread of forestry.
It was important to get a picture of all of Ireland, both North and South, therefore the RSPB were invited to present the status of curlews in Northern Ireland. Neal Warnock form Country Antrim set the overall picture, showing that it is estimated there are between 250 and 560 pairs left, mainly in Antrim and Fermanagh, and is thought to be closer to the 250 mark. A survey in 1987 showed 5000 pairs, making a dramatic 82% decline.
Neal manages the RSPB Curlew Trial Management Project area, Glenwherry in County Antrim, one of the six upland sites identified for research by the RSPB across the UK. (https://ww.rspb.org.uk/our-work/conservation/conservation-projects/details/408821-glenwherry-breeding-wader-project)
Figure 2- location of GlenwherryGlenwherry is a region of rough pasture and bog and has around 46 pairs of curlews, which has remained more or less steady (with some ups and downs) for around the last 10 years. In farms that were receiving targeted advice and help between 2011 and 2014 (the HELP project) numbers increased from 24 to 29 pairs and hatching rates also increased.

Neal highlighted the areas of concern in Northern Ireland as:
The other important area for curlew in Northern Ireland is the Lakeland area of County Fermanagh and Brad Robson presented the picture for the birds on the islands in the middle of Lough Erne. https://www.rspb.org.uk/our-work/conservation/conservation-projects/details/408824-lough-erne-breeding-wader-project

Removal of scrub, opening the landscape and protecting against predation (with electric fencing) have all helped curlew breeding. There are around 40 pairs in the area but overall the trend is still downwards. Brad stressed we need to know much more about the requirements of the birds in the breeding season, especially what happens to the chicks between hatching and fledging. He thinks that seemingly minor changes in the environment can have major effects. Often the birds are disappearing due to small, incremental changes at the field level such as a small amount of drainage, building of houses, planting of shelter belts and so on. He said that curlew were declining due to “death by a thousand cuts” as well as from large scale changes to the landscape.
Two presentations from BirdWatch Ireland surveyors showed how damaging drainage and peat extraction were to breeding birds, especially where there are only a handful of birds left. Both Michael Bell, from County Sligo and Paddy Sheridan from County Kildare painted a bleak picture. Birds that once nested on wet, boggy ground had disappeared when large drains were dug through their territories, and in some areas illegal turf cutting on protected bogs had destroyed nests and chicks. Over two years, no pairs bred successfully in Kildare and there were probably no more than two nests in the whole of County Sligo. Historical references from books and surveys referred to Curlew as being numerous and plentiful and so their observations painted a depressing scenario. Predation by foxes and crows and burning of bog was also highlighted as a threat to the birds, but despite illegal damage to protected areas, no prosecutions have been brought.

Mark Craven – a Predator Control Officer for the National Parks and Wildlife Service, discussed the problem of having to operate alone over a large area for a limited time with high numbers of mink, fox, hooded crow and magpie. Although there is a general acceptance of the need for predator control in Ireland, Mark felt an awareness campaign would be very welcome to engage local gun clubs and farmers to help with controlling predators on curlew areas in particular, and more funding needs to be found to support them. The efficacy of predator fencing versus lethal methods was discussed.
David Buckley from the government’s Department of Agriculture, Food and the Marine gave an overview of the new GLAS (Green Low-Carbon, Agri-Environment Scheme). Having curlew on their land enables farmers to enter the scheme and receive financial help and guidance. 280 have joined so far and there are places for 716.
David Fallon from the commercial peat extraction company Bord na Mona gave a presentation on their bog restoration projects which they hope will attract waders.

Bord na Mona provides peat for Ireland’s three peat powered power stations, but the company plans on phasing out using peat as a fuel in 10 years, replacing it with bio-fuels.
A presentation from Rachel Taylor from the BTO (https://www.bto.org/national-offices/wales) on her joint work with the RSPB in N Wales provided interesting background and highlighted areas that need more research. Rachel and Steve Todd (RSPB) have tagged 3 male curlew in the Migneint area of N Wales near Mount Snowdon. The birds are nesting on rough pasture and the results show how much they move around in the breeding season, often targeting the same areas to feed. Close grazed sheep pasture is very important as a feeding area. One bird flew 3 km away to roost overnight by a small pool. These results have yet to be fully analysed and many more birds need to be tagged to increase the data set, but intriguing questions have been raised. Do males and females use the breeding landscape in the same way? Why are they selecting certain places to feed? How do farmers’ activities affect feeding during the breeding season?
The second part of the day consisted of workshops and was chaired by Alan Lauder, an independent ecologist. People were invited to attend two out of three choices. Maurice Eakin from the NPWS held the workshop on curlews on bogs, Alex Copeland from BirdWatch Ireland ran the curlews and farming sessions and Simon Lester, an experienced gamekeeper from England, ran the workshop on predator control. The findings were then presented to the whole group in a plenary session. The conclusions of the conference are being summarised by two academics, Barry McMahon from University College Dublin and Juliette Young from the Centre for Ecology and Hydrology in Edinburgh, and will be circulated shortly.
One major step forward that emerged from the day in New Forest was the setting up of a Curlew Task Force to push for curlew conservation measures to be enacted before the next breeding season. Numbers of curlew are so low Ireland cannot afford to lose more birds by not protecting chicks next spring. The actions of the Task Force will be published soon, but hopes are high for fast and effective measures to be put into place before March.
