Nearly all of Alderney’s 8,000 gannet nests are contaminated with plastic pollution. As recently as 20 years ago, only small quantities were seen in the nests, the Alderney Wildlife Trust (AWT) said. The plastic build-up in the breeding colonies is killing the seabirds, with some entangled gannets found hung or missing legs, it added. The plastics found in the nests are largely from fishing industry rope or line and gannets are known to forage as far as 20 nautical miles to collect nesting materials
The island, 10 miles (15km) from France and home to 2,000 people, hosts around 2% of the global gannet population. “Over the last 20, 30 years we’ve gone from little bits of plastics here and there to every nest now, pretty much, having a significant quantity of plastic in it,” the Trust’s Roland Gauvain said. The plastic build-up is posing a “significant risk to chicks and adults alike as they become entangled or end up eating it”.
“It’s not uncommon to find gannets hung – to lose legs, to find their wings entangled.”
AWT further highlighted concerns over plastic pollution across the British Isles, along with sewage spills and a build up of waste on beaches (see The Wildlife Trusts).
Alderney’s gannet population is still growing, but Mr Gauvain said the Island’s position in the English Channel meant it was particularly vulnerable to plastic pollution. “Most of these plastics aren’t going to be coming from Alderney,” he said.
“We have a population of 2,000 people and we’re talking about upwards of 8,000 nests on the colonies. “Really, the tale is that we are impacting our waters so much more than we ever realised.”
