new Warré forum in English
There is now a lively Abbé Warré/vertical top bar hive forum in English at http://www.biobees.com/forum with links to David Heaf's translation of Abbé Warré's book 'Beekeeping For All'.
A forerunner to Abbé Warré's hive: the Abbé Christ hive
Over Christmas I translated the document that prompted me to experiment with beekeeping in Warré hives. I have put it on the net for free download at http://www.mygarden.me.uk/thur.pdf. It comprises a couple of chapters from 'Beekeeping: natural, simple and ecological' by
by Johann Thür translated from Bienenzucht. Naturgerecht einfach und erfolgsicher (Wien, Gerasdorf, Kapellerfeld, 2nd ed., 1946). I found it so convincing that I asked the beekeeper at the Goetheanum in Switzerland who sent it me for plans of such a hive. In reply he said that the hive concept had been updated and that the Warré design is now used.
Thür argues that for maximum bee health a hive should mimic as near as possible the situation in a cavity, say in a hollow tree, occupied by wild/feral bees. The most important thing to not about this situation is that the combs are fixed to the roof of the cavity and to some extent to the walls. The arrangement forms cul-de-sacs or spaces between the combs that are open only at the bottom. With this arrangement, there is nowhere for rising currents of warm air to go. It observes the principle of what Thür referred to as 'Nestduftwärmebindung' which one could translate as 'retention of nest scent and heat'.
Thür then goes on to describe a type of hive that strictly observes this principle. It is the hive of Abbé Christ (1739-1813). From Thür's description of it, it is clear that it is identical in concept to Warré's. Not only that, but also, if correct conversion of the old French units of measurement are used, the internal plan of a Christ hive body appears to be 30 x 30 cm, itentical with Warré's. Yet the two men are believed to have reached their hive designs independently.
Whilst I can only speculate what retention of nest scent means in terms of health for the bees, I think that nobody will have difficulty with the concept of retention of nest heat. It would be an interesting task for bee science to study the importance of the quality, composition and integrity of the pheromone-laden atmosphere between the combs for bee health.
P.S. In case there is any misunderstanding I should like to add to Chris Jeppesen's post. There are indeed beekeepers who insert frames in Warré format hives, but this modification greatly departs from Warré's intentions which are further supported by the article mentioned above. The least intrusive type of frame I have seen is that of Roger Delon. To the Warré top-bar is added a length of 3 mm stainless steel wire round the three remain edges of where comb will develop to. For those living in legislatures that tell beekeepers what kinds of combs to use, this would be an option for staying within the law.
I have started a Warré beekeeping e-group:
