The bees I rented in spring 09 were Russian bees. There were 2 hives. One entire box swarmed into a VERY dead poplar tree in my yard. There is a hole about 30 ft up where they seem to be very content. They have been there since June 09. My fear is that the tree will not make it through another year. (10' sections of branches have been falling from the top for awhile.) I am not opposed to leaving it alone, but concerned for the bees if much more of the tree deteriorates. The owner would like to collect them back, but since it has been so wet, there was no way to get any equipment to the tree, plus the owner of the bees has no equipment, so we will be the ones to have to get the tree down. Any opinion on this would be greatly appreciated.
