What they are up againstKeeping a colony alive is not a given.
In the winter of 2019/20, Spanish beekeepers lost more than a third of their colonies — the heaviest losses of the thirty-seven countries surveyed. The causes stack up: the varroa mite, which reached Europe in the seventies and has never left; pesticide residue in the forage; scrubland cleared for other uses; and, on the plateau, summers that arrive earlier and drier every year.
Every colony we keep is fed through the lean months, treated for varroa twice a year, and moved only with the season. None of that is free, and none of it is certain. Adopting a bee pays for the part of the year when a hive gives nothing back.
