Hedgehogs

Who doesn’t love hedgehogs. Everyone is won over by that snuffly little nose and beady eyes. However a recent report indicated that the rural population has halved over the last fifteen years. Hedgehogs are holding on in urban settings, but are disappearing more rapidly than ever in the countryside, as hedgerows and field margins are lost to intensive farming. The decline appears to be even worse in Scotland than south of the border.

The loss of hedges and woodland across Britain, in the drive to create larger fields, has resulted in fewer nesting sites and less space for hedgehogs. The large-scale use of pesticides has reduced the amount of food for them to eat. Hedgehogs are generalists, but rely mainly on invertebrates such as beetles in the countryside.

Rough estimates put the hedgehog population in England, Wales and Scotland at about one million, compared with 30 million in the 1950s.

Highland Titles, already moving forward to support the endangered water vole, wondered how to help and was moved by the South Uist hedgehog cull – a sad story with a happy ending.

The story began in the 1970s, when some hedgehogs were released into a garden on the Scottish island of South Uist, presumably to reduce the number of garden pests. Before that time, South Uist had no native hedgehogs.

North Uist, Scotland

The hedgehogs soon multiplied and spread, lacking competition, natural predators, pesticides or busy roads. Every spring, the sandy soils along the western beaches of these islands are covered with a carpet of grasses and wild flowers. This “machair” is a valuable breeding site for globally important bird populations, including dunlin, ringed plover, redshank and oystercatcher. The hedgehogs were soon implicated in a massive decline in populations of these birds through predation on their eggs and chicks.

So fifteen years ago, the Uist Wader Project was formed as a coalition between Scottish Natural Heritage, RSPB Scotland and the Scottish Government, to undertake a cull of the hedgehogs, in order to save the nesting waders. The project created a division among conservationists, with many groups angry that the much loved hedgehog, was being killed at the same time as it was under threat on mainland Britain. So in the same year as the cull began, a coalition of animal welfare organisations and charities formed Uist Hedgehog Rescue (UHR).

UHR agreed that the hedgehogs were an exotic import to the islands and were causing problems to the local ground nesting birds. However they offered an alternative solution. They proposed to trap the hedgehogs and relocate them to the mainland, to help boost the declining Scottish population.

During the next three years they relocated more than 700 hedgehogs, and most importantly they showed that relocation of the hedgehogs  was both feasible and effective. A study using radio tracking was undertaken by Hugh Warwick, an ecologist and journalist. He demonstrated that most animals survived the process and so a few weeks later, in early 2007, the cull was stopped. Instead of killing the animals, Scottish Natural Heritage began to fund the translocation project run by UHR instead. Almost £2.7m  has been spent on removing 2441 hedgehogs from the area over the last 13 years – at a cost of £1097-a-hedgehog.  Several million pounds will be required to finish the task of removing at least 4000 more hedgehogs.

Highland Titles have now embarked on creating the largest hedgehog sanctuary ever built, with a view to offering a safe home to hedgehogs permanently disabled and therefore unsuitable for release. Work has begun and we will let you know when it receives its first residents.
