Wildlife expert Chris Packham has vowed that that he won't 'buckle' after a suspected arson attack at his Hampshire home.
The broadcaster, who campaigns for a ban on hunting, posted a message on social media after a car was set on fire outside his house in the New Forest.
He said two men wearing masks set a vehicle on fire at the gate shortly after midnight on Friday, where it exploded, causing "extensive damage".
Hampshire Police confirmed it was investigating the incident.
In the video on Twitter, Packham said the attack was the price of on-line abuse he regularly receives, and questioned whether it was the work of conservation groups, rural campaigners or hunt supporters.
He also spoke of his frustration that the harassment and hate which he sees on his timeline cannot be dealt with effectively by police.
"Perhaps the cost is having my gate burned down, causing thousands of pounds' worth of damage."
In the past, Packham has reported a number of dead animals being left outside his house, "but now it's escalated", he said, "because they've taken to damaging that property".
If anything, he said the incident had emboldened him, and he would not bow to the pressure to support activities he did not agree with, such as "illegal shooting" and trail hunting.
"If you think that by burning down those gates that I'm suddenly going to become a supporter... then you're wrong," he said.
"I will just carry on, because I have no choice. I cannot and will not let your intimidation sway me from my cause."
