reckless. Statistically, in Germany, there are around two colonies per km2. According to Seeley, with good food supply conditions existing at his location, there were five colonies per km2. But these average numbers say nothing about agglomerations in some areas.

Checklist: Is my apiary location compatible with natural standards? Condition Number of colonies at the location Flight radius (colonies/km2) Placement of the colonies Nest direction Height of the nest entrance Food supply in spring

Solar heat A careful selection of location can also strengthen the self-healing capacity of colonies. Every day in healthy colonies, 100 to 1,000 bees die away from the nest, particularly in regions with long winter periods. Colonies must have the opportunity to fly out to defecate and get rid of ill bees as often as possible. For this purpose, bees must be able to recognise the weather in winter and spring, and when it is good enough for them to fly. If the entrance hole of the hive faces south it is easier for them. Therefore, it is not surprising that wild swarms prefer entrance holes facing that direction.

From their choice of location we can learn a lot from the bees. Those beekeepers who want to practise natural beekeeping should try to meet the bees’ requirements as perfectly as possible.

Brazilian researchers published an article in the April edition of the journal Plos One, concerning how indigenous bees, such as stingless bees, can help low-income communities to earn additional revenues, reduce the need to exploit other natural resources, and create incentives to protect the environment. Stingless bee keeping helps protect many indigenous bees along with their pollination services, which assure crop yields and help to maintain plant biodiversity in many natural ecosystems.

In Brazil and across developing countries, stingless beekeeping remains an informal activity, with a range of different management practices. Stingless beekeeping could help protect the bees, safeguard their pollination 5
