Walkers in East Lothian have been urged to be vigilant in avoiding encounters with Britain’s only venomous snake while enjoying some of the region’s most spectacular scenery.
Countryside rangers say adders are likely to be more visible in the coming weeks as they bask in the spring sun after emerging from hibernation in March.
The secretive serpents, which can grow to more than two feet long, generally avoid contact with humans, but can produce a nasty bite if accidentally stepped on.
Wildlife experts warned parts of the Lammermuir Hills are home to the snakes - identified by the distinctive zig-zag patterns on their backs - but they can often be missed by those taking in the peaceful surroundings.
They have now warned increased awareness when walking in the hills near the borders.
Despite their reputation, adder bites are only dangerous to the young, old or ill, however can cause painful inflammation in those without any pre-existing conditions.
In some cases, the snakebites have been revealed as a cause of death for family pets, particularly dogs.
“The adder is the UK’s only venomous snake, but it’s poison is generally of little danger to humans,” the ranger service said.
“The bite can be very painful and cause a nasty inflammation but they are very timid snakes and bite only in self-defence during attempted capture, handling or if accidentally stepped on.
“Adders can be found in the Lammermuir Hills and can often be found basking in a sunny spot.”
Despite being a protected species, adder populations across the UK have gone into swift decline according to research in 2019.
Findings published in the Herpetological Journal stated a combination of habitat mismanagement and bad publicity for the snakes was threatening their existence.
Research stated that the species could be “all but extinct” by 2032 if current trends continue.
