BAN SPOTLIGHTS THREAT OF ALIEN SPECIES TO GLOBAL ECOSYSTEMS ON INTERNATIONAL DAY

The spread of non-native species are harming ecosystems, livelihoods and economies around the world, Secretary-General Ban Ki-moon stated in a message to mark the International Day for Biological Diversity.

Mr. Ban noted that the global decline in biodiversity remains "alarming," despite agreement at the World Summit on Sustainable Development to significantly reduce the rate of loss by 2010. The main causes include deforestation, changes in habitat and land degradation, often linked to the growing impact of climate change.

Another threat, and the focus of this year's observance of the International Day, is the spread of invasive alien species, such as zebra mussels that affect shipping, fisheries and electric power generation in the Great Lakes of North America, and plants such as wattles in South Africa.

"An unwanted by-product of globalization, non-native species are harming ecosystem services, livelihoods and economies throughout the world," said the Secretary-General, adding that the implications for poverty reduction and sustainable development are "profound."

He highlighted the Convention on Biological Diversity, which is addressing the threat of invasive alien species by setting global priorities and guidelines, sharing information and expertise, and helping to coordinate international action.

"The most cost-effective and feasible method of control is prevention," he stressed. To be successful, this strategy requires collaboration among Governments, economic sectors and non-governmental and international organizations.

"A country can only prevent invasions if it knows which species may invade, where they may come from and the best management options for dealing with them."

Individuals, too, have a responsibility, he added. "Abiding by local and international quarantine and customs regulations will prevent the spread of insect pests, weeds and diseases. A simple rule applies: leave living organisms in their natural habitats and bring home only memories."

Mr. Ban emphasized that controlling invasive alien species and addressing the other causes of biodiversity loss is an increasingly urgent task. "I urge all Governments, organizations and individuals to renew their efforts to protect life on Earth."
