European Environment: alarming decline in plants, molluscs and freshwater fish

IUCN 22 Nov 11;

Europe's natural heritage is showing an alarming decline, according to new research published today. The European Red List, a part of the IUCN Red List of Threatened Species™, assessed a considerable portion of Europe’s native fauna and flora, finding that a large proportion of molluscs, freshwater fish and vascular plants now fall into a threatened category.

The assessment of some 6,000 species reveals that 44% of all freshwater molluscs, 37% of freshwater fish, 23% of amphibians, 20% of a selection of terrestrial molluscs, 19% of reptiles, 15% of mammals and of dragonflies, 13% of birds, 11% of a selection of saproxylic beetles, 9% of butterflies and 467 species of vascular plant species are now under threat.

European Commissioner for the Environment Janez Potočnik said: "The well-being of people in Europe and all over the world depends on goods and services that nature provides. If we don’t address the reasons behind this decline and act urgently to stop it, we could pay a very heavy price indeed."

Freshwater molluscs are the most threatened group assessed so far. Spengler’s Freshwater Mussel (Margaritifera auricularia), once widespread, is now restricted to a handful of rivers in France and Spain. Currently listed as Critically Endangered, it was considered to be nearly extinct in the 1980s. The species is one of two for which a European-level Action Plan was designed and there are ongoing conservation programmes which allow hope for its future.

“The figures confirm the worrying condition of European molluscs,” said Annabelle Cuttelod, IUCN Coordinator of the European Red List. “When combined with the high level of threats faced by freshwater fish and amphibians, we can see that the European freshwater ecosystems are really under serious threats that require urgent conservation action.”

Freshwater fish are also highly threatened, especially as a result of pollution, overfishing, habitat loss and the introduction of alien species. Sturgeons are particularly at risk, with all but one of the eight European species now Critically Endangered.

Included in the vascular plant category are the wild relatives of crop plants which are vital for food security yet are often neglected in terms of conservation. The Critically Endangered Beta patula is a close wild relative of cultivated beets and an important gene source for enhancing virus resistance. Other plant species that show concerning levels of threat are the wild relatives of sugar beet, wheat, oat and lettuce which are economically important crops in Europe.

But there is some positive news and the assessment highlights the success of well-designed conservation measures. Many species protected under the EU Habitats Directive and included in the Natura 2000 network of protected areas now have an improved chance of survival. Centranthus trinervis, a plant endemic to Corsica, has been downlisted from Critically Endangered to Endangered due to strict protection of its single known site. Additionally, the control of invasive species such as plants, goats and rats for example has benefited the majority of threatened land snails in Madeira over the past 10 years.

“These are encouraging signs that show the benefits of conservation actions supported by strong policy,” says Jean-Christophe Vié, Deputy Director, IUCN Global Species Programme. “Continued implementation of the current European legislation combined with new conservation programmes is essential to preserve these important native species and their habitats.”

EU sounds alarm for threatened freshwater species
BBC News 23 Nov 11;

Many of Europe's freshwater fish and molluscs are now threatened species, a new EU study shows.

The European Commission called for urgent action to preserve the diversity of Europe's wildlife.

Pollution, overfishing, habitat loss and alien species are blamed for the decline in species.

The latest findings are based on a study of some 6,000 species for the European Red List - an assessment of threats to wildlife.

The list of Europe's threatened species includes 44% of all freshwater molluscs, 37% of freshwater fish, 23% of amphibians, 19% of reptiles, 15% of mammals and dragonflies and 13% of birds.

The Commission says 467 plant species are also under threat, including wild varieties of crops such as sugar beet, wheat, oats and lettuce. Such species are "vital for food security yet are often neglected in terms of conservation," the Commission says.

The Commission has urged the 27 EU member states to adopt sustainable farming and forestry methods to halt biodiversity loss.
Nature's 'goods and services'

"The well-being of people in Europe and all over the world depends on goods and services that nature provides," said EU Environment Janez Potocnik. "If we don't address the reasons behind this decline and act urgently to stop it, we could pay a very heavy price indeed."

There are some notable successes however for wildlife conservation in Europe.

The EU's Natura 2000 conservation network of protected wildlife areas aims to give endangered species a better chance of survival. Corsica's Centranthus trinervis plant and the land snails on Madeira are showing signs of recovery, the Commission says.

A biodiversity expert at the environmental group Friends of the Earth, Paul de Zylva, says the thriving otter population in the UK is also a success story - a sign that the healthy fish they prey on are abundant in once-polluted rivers.

But many of Europe's water species are suffering, often because their natural habitat is disappearing, he told BBC News.

"Our water resources are a symbol of whether we are getting environmental policies right," he said.
Threat from aliens

Invasive species from other parts of the world often spread through Europe's rivers, he said. Among them are Chinese mitten crabs, Himalayan balsam and Japanese knotweed. Rivers disperse plant seeds across borders - one reason why co-ordinated European action is necessary, he said.

It is vital for the EU to provide the right financial incentives for farmers to boost nature conservation when a revised Common Agricultural Policy takes effect after 2013, he said.

The Natura 2000 network was expanded this month, taking in an additional 18,800 sq km (7,259 sq miles) - most of that being marine areas.

The UK has added some biodiversity hotspots in the Atlantic, including reefs off Rockall Island.

In the Mediterranean, marine habitats of endangered turtles and monk seals have also been added to the list of more than 26,000 European conservation sites.
