I also chatted with John from Delta. He has been doing mason bees for quite a few years now and he is a true experimenter. Every year he comes up with ideas that he tries out. On my visit this time, he told me that for the first time last year he was able to beat the wind. He has a very cold wind coming off the sea in the early spring. He had seen the various yurt design and found them too complex. I saw his design, and I think it is a good one. It is simple and anyone can set it up. Last year it worked well. It works similarly like a yurt, but you do not have a hole in the hexagonal roof. More on this subject when John sends me his pictures and a story.
Aan update- we could not figure out what to call this structure at first. A Mason Bee Field Shelter describes it nicely.
If any one has story to share, send me pictures and a story about bees and pollination- Thanks. I think a lot of people will enjoy reading it. On average, 70 pages are read on this blog every day. Quite amazing.
