@miksha I know a great beekeeper in the area who's interested in rescuing Apis silvarum – now very rare, but apparently they can be still found in what remains of the old forests in my area. I convinced him (I hope) not to keep his A. melifera near the national park we border with, but A. silvarum could be something worth giving a try.
@szescstopni You have a good point. One or two honey bee colonies ‘might’ not be disastrous, but they could have an impact. Every place is different in that respect. If you don’t feel comfortable keeping bees because of their ecological impact, that’s really appreciated.
