The photo above is a paulownia tree in East Hanney with honeybees living inside it. Tree cavities were the original home of the honeybees. Today, tree cavities are few and far between in the UK and many trees with cavities tend to be felled for safety reasons.
At this point in time, honeybees tend to live in hives because of beekeepers. Although honeybees have been known to live in man-made structures, such as wall cavities, which often creates a nuisance.
Wooden hives do not possess the superior thermal properties of tree cavities and this is why I am a proponent of polystyrene hives (see yesterday’s blog).
