Bees do quite nicely in the deep desert. The honey flow is in the winter/early spring when the desert shrubs are in bloom. It isn't a great flow and beekeepers won't get much, but it's enough for bees to make enough honey to get by. Some beekeepers overwinter their migratory colonies down there to give the bees a chance to forage and build up until they are ready for the almonds. There are not too many days in the year when they can't forage, so there are year-round (albeit small) opportunities for them. Any housing nearby is a bonus because people naturally plant flowery things.
