Campaigners against badger culling and blood sports have staged a protest through central London to Downing Street.
Springwatch presenter Chris Packham was among the crowds calling for an end to the slaughter of wildlife.
He earlier described such activities as a "dying business".
The protests called for an end to the controversial practice of badger culling, as well as driven grouse shooting in which birds are flushed out towards shooters.
Marchers also urged Prime Minister Theresa May to keep the ban on fox hunting.
Many of those taking part carried banners stating "Kill the Cull" while some wore fox and badger masks.
They chanted "Save our badgers, stop the cull", "Save our foxes, keep the ban" and "There's no excuse for animal abuse".
Both badger culling and blood sports remain contested issues.
Some farmers say that killing badgers helps to prevent the spread of TB to cattle, though that claim is disputed.
Mrs May also revealed that she had "always supported fox hunting" and would be in favour of holding a free vote over rolling back the current ban before the last general election.
That policy has since been dropped, with poll suggesting that the majority of Britons back the current ban.
Amanda Anderson, Director of the Moorland Association, said that shooting events could help preserve the countryside and could boost the rural economy.
“It is a great pity that those calling for a ban on shooting on the moor ignore the very substantial social, economic and environmental benefits that moorland management provides," she said.
"The habitat is managed all year and there is only eight days shooting. It helps preserve and enhance precious heather habitat, protect it from wildfire and is at the forefront of the UK’s peatland restoration."
