I'm touring southwest England in October and plan to stealth camp. I've been camping here in Canada for some years and have experienced some discomfort and fear because of the local plants and animals.
Here in Canada, one might expect a number of daytime and nocturnal visitors to ones camp site; squirrels and chipmunks are annoying and some consider them 'cute'. Raccoons can make an aweful mess of your food stores. So can bears, but the bruins are another concern as some can fatally injure campers. I guess I should be pleased that in the form of insects, only blackflies and mosquitos can cause much pain here in the colonies.
As for plants, contact with poison ivy and oak can cause much grief and a trip to see the doctor.
While I'm camping in England what kind of animals, insects and plants should I be careful to avoid?
