Beginning immediately, Bee Tree Hives will now come with an Eco-Floor instead of the previous Base. Here's why:
Honey bees are not designed to live in thin-walled, over-sized, smooth, sterile boxes... to which poisons are routinely added. Rather, they are designed to live in small, thick-walled, rough-surfaced hive cavities which are also occupied by over 8,000 other known organisms - from yeasts, molds, and fungi, to ants, mites, and beetles. A colony of honey bees, in a proper hive environment, lives in symbiotic relationship with these other organisms, and this symbiosis contributes to colony health in ways that we have not yet begun to fathom.
No species in nature lives in a sterile environment, completely isolated from other organisms. And yet, with the Langstroth hive, and the accompanying practices of conventional/commercial beekeeping, that's exactly what we've been forcing honey bees to do.
Here is a video by Phil Chandler that explains the how and why of an eco-floor:
