Breeding wader conservation in West Pomerania

Posted by

By Stephen Inglis, RSPB

From 10th – 17th June 2019 myself and colleagues from other Scottish conservation NGOs took part in a course on managing wetlands in Poland. The course was developed by ARCH and funded by Erasmus+. During our visit we were hosted by Society for the Coast and visited various sites across West Pomerania, the north-western section of the country.

Several of the wetland sites that we visited were breeding sites for waders and I took the chance to find out about the conservation issues that these birds are faced with in Poland. In West Pomerania breeding waders include Northern Lapwing Vanellus vanellus, Common Snipe Gallinago gallinago, Eurasian Curlew Numenius arquata and Common Redshank Tringa totanus. Although the wader breeding season was drawing to a close at the time of our visit we were still able to see the habitats where the birds had recently been breeding and learn of the threats they are faced with.


Similarly to Scotland, we were informed that one of the largest pressures on breeding wader productivity was failure due to high levels of predation. With large populations of non-native American mink Neovison vison and racoon Procyon lotor widespread across the region and increasing red fox Vulpes vulpes numbers, mammalian predators are an increasingly important driver of low levels of productivity.

Despite the negative impacts of mink and racoon our tour guides explained that significant control of their populations is considered unfeasible given the current size the populations. At Ujscie Warty monitoring is carried out using floating platforms in addition to weekly roadkill counts on the two main roads on either side of the park. Both suggest that populations are increasing despite removal of both species at the start of the bird breeding season.

In recent years fox numbers are thought to have increased as a result of reduced hunting pressure in the absence of demand for fox fur coupled with a decline in the prevalence of rabies – the latter has been achieved via the distribution of vaccine laced baits. Very few foxes appear to be taken by hunters and in national parks such as the Wolinski National Park, with an area of 110km2, a limit of 5 foxes are permitted to be removed each year. In contrast to Scotland where sheep farming is common, sheep are largely absent from West Pomerania, and as a result of this reducing fox numbers is unlikely to receive as much interest from landowners.

Water management and weather patterns

Although many of the breeding waders present on the wetland sites we visited typically nest on islands created by high water levels, in recent years unreliable rainfall levels have resulted in nesting areas being increasingly accessible to these mammalian predators. At the Ujscie Warty National Park where breeding waders including Lapwing and Redshank usually do well, this year breeding success has been extremely low. Following a year of low rainfall in 2018, water levels in the wetland during spring 2019 were several metres lower than what would be expected and as a result foxes have been able to den on the islands where waders are usually able to nest safely. This, in combination with the impacts of other predators has resulted in very few chicks making it to fledging. Indeed, during our boat tour of the Ujscie Warty our tour guide remarked that a juvenile Lapwing we saw may have been one of the only ones from this year.

In addition to the lack of rainfall, our tour guides often mentioned that when rain does occur it more often occurs as extreme rainfall events and this also causes problems for breeding waders. At Ujscie Warty our tour guide told us of how a Redshank nest that they had been monitoring this year was flooded out following one such rainfall event this year. Wader conservationists in the UK are familiar with this phenomenon as well, as it is a key cause of breeding failure for Black-tailed Godwits Limosa limosa nesting on the washes of the south-east of England.

The Odra Delta Nature Park is fortunate in that water levels in the past have been able to be controlled through the use of water pumps but in recent years this power has been removed by the government. This has resulted in lower water levels and reduced winter and spring flooding but it is hoped that in future years some compromise might be able to be achieved.

Grazing management

Grazing management in Poland currently appears to be wader friendly and it was encouraging to hear that many efforts are being made to make sure grazing is appropriate. At Ujscie Warty, large extents of the park’s floodplain meadows are rented out to local farmers for cattle grazing. Although farmers are keen to get stock out onto the meadows as soon as possible, the park authorities make an attempt to prevent cattle introduction until the second half of June to reduce trampling risk to wader nests but also prevent excessive damage to soft wet ground.

At the Odra Delta Nature Park Konik Ponies and Highland Cattle are being used to mimic the grazing style of the extinct Tarpan or Wild Horse Equus ferus and Auruchs Bos primigenius in order to create the swards necessary for the range of breeding meadow birds present including several breeding wader species. Managers of the park aim to achieve a density of roughly 0.5 animals per hectare but in recent years the herd size has increased well beyond the desired levels due to high levels of productivity. Our tour guide explained how they are starting to resolve this problem by a combination of selling and donating stock to other projects across Poland where there is a need for conservation grazing.

In Scotland sheep are often considered an issue for nesting waders as high densities can result in unsustainably high levels of nest trampling and very short uniform swards but in Poland the absence of sheep means this is not an issue. It was very interesting to hear of the lack of interest in sheep farming in West Pomerania – despite trials suggesting that some species rich grassland sites might benefit from light sheep grazing farmers who were offered sheep refused to keep them. A stark contrast to the uplands of Scotland!


Another realisation from our visit was that many of the conservation projects aimed at breeding waders in West Pomerania don’t have the resource or funding to allow for detailed monitoring of the impacts of such management. I feel that the scale of the management occurring on sites such as Ujscie Warty and the Odra Delta Nature Park could provide excellent case studies into how best such large sites can operated to achieve the greatest results for breeding waders.

Comments on Butterflies in West Pomerania 10th – 17th June 2019

During our visit a large Painted Lady Vanessa cardui influx was occurring, possibly in association with the weather patterns which had resulted in the above average temperatures which Poland was experiencing. Wherever suitable food plants were available, such as Viper’s Bugloss Echium vulgare, the Painted Lady could be seen in large numbers forming light clouds when disturbed. Other butterfly species to be seen included Small Tortoiseshell Aglais urticae, Red Admiral Vanessa atalanta and a probable High Brown Fritillary Argynnis adippe but these were by far outnumbered by the mass of Painted Lady. Bumblebees were a scarce sight but this might have been due to the high day time temperatures suppressing foraging activity.
