The rapid expansion of green ring-necked parakeets in the UK has sparked concern among scientists and conservationists, who worry that this invasive alien species may have negative impacts on native bird populations.

The #EU Deforestation & Forest Degradation Regulation is due to come into force in 2026. It will ban products made using raw materials from deforested areas on the EU market.
