Hunt sabs: British wildlife’s first line of defence
A day in the field seeing direct action in defence of wildlife first hand gave DAWN EVANS hope for the desperate fight to save biodiversity

THE Cop15 UN Biodiversity Summit, billed as the last chance for the world’s ecosystems to be saved, is currently taking place in Montreal, running from December 7-19.
The summit’s statement of intent reads: “Governments from around the world will come together to agree on a new set of goals to guide global action…to halt and reverse nature loss.”
That is the aim — but shocking UN statistics reveal that over the last 40 years there has been over 70 per cent decline in wildlife globally, and scientists say that a million species are now at risk of dying out. Britain is among the bottom 10 per cent of the most nature-depleted countries with one in seven species at risk of extinction.
