This is the second time we’ve had visitors to the bee yard. The hives are surrounded by an electric fence. Though the jolt it gives is pretty beefy, it’s not a very substantial enclosure. Some beekeepers we know have gone all out Fort Knox in terms of fencing.

We have (had) two “swarm boxes” outside the perimeter of the electric fence. The objective of the swarm boxes was to capture any bees who got ideas about relocating. Our visitors, the bears, knocked down both swarm boxes–smashing one of them. There was nothing in them–so the loss is just the boxes themselves.

These bears must have experience with bee hives and electric fences. I say this, because the fence controller is in a box that looks like a bee hive–and the bear(s) upended that. No luck there. But, they (it) never breached the fence line. The bees remained unmolested. We had a similar visit last year–again they took down the swarm boxes. But so far, the bees are fine.

I’ve seen hives ravaged by bears. They just demolish the entire hive structure. We are holding our breath, hoping that the bears (bear?) are  put off enough by the wires to keep clear of the enclosed space.

 

Good Fences Make…

It’s nearly time to put in the garden, and that means that we need to make fence decisions. Our biggest garden problem is deer. The deer are also a threat to the orchard saplings. We’ve combined the garden location with the orchard to consolidate fencing needs. We’ll also have the bees in the corner of the garden, which complicates things a bit. Locally there is a split on the type of fencing or garden protection needed from the deer. (Oh yeah, and from the bunnies, too.) No matter what you do, it’s expensive.

Some install tall traditional fencing—at least seven feet tall. Others go the electric route and install a multi-strand electric fence. One neighbor has completely foregone fencing. They protect their garden with a motion detector connected to a sprinkler system. We walk by regularly and we laugh when our meanderings, on the road, trigger the sprinkler response. Hey, I guess it works! (If not for the bees, I’d be tempted to go this route.)

The uber-tall solution looks fortress-like and it’s permanent. I’d like a little more flexibility to move the fence, in the future, when the garden expands.

So, I stepped into the vast world of electric fencing. Too many decisions! What’s the power source? Is it close enough to the house for AC power? (Not really, we’d have to underground several hundred feet of wiring for that.) That leaves us with the choice of solar, or DC. Solar sounds so….progressive and green. I was predisposed to that direction. Unfortunately, my research into reliability and power needs revealed that the system that would meet my needs (and have the warranty life I’d want) would be prohibitively expensive. That leaves us with 12 volt, DC batteries.

The pebble in the shoe of all these plans has been the bees. You see, bees attract bears. (The hives down the road were raided by a bear, last summer—it isn’t a hypothetical problem.) An electric fence system strong enough to get a bear’s attention has to be pretty beefy. Fence controllers are rated in several ways, by distance, by ‘joules’, and by the type of hazard (animal) contemplated. Though a “5 mile” fence would be fine for deer, to get the kick you need for bear, a 25 mile fence is needed (even though the fence dimensions themselves don’t change—it’s not the length of the fence that counts, it’s the total length of the wire strands you use.) A bear fence calls for a minimum of four strands. Some contend that seven is required. Not that appearance is the arbiter, but a seven-strand fence looks like a maximum security prison—minus the razor wire. (One beekeeper actually suggested a double fence—with a 30 inch no man’s land between them!) I think we’ll go with four strands. The fence must deliver a minimum of a one joule charge to dissuade a bear. That same power will make our fence pretty unfriendly to incidental human contact. It’s not a ‘leaning on the fence talking to neighbors’ kind of a fence. We worry about the cats.

All of this has been Greek to me. I’ve been researching the fencing on the internet. It’s quite an education. For every fencing option, there are at least three alternate opinions. Unfortunately, our tailored needs will make it near to impossible to pick anything up second-hand. I have about a week to make up my mind. By then, our seedlings will be busting out of their pots, begging for a permanent home in the garden. And right after that, about the first week in June, the bees will arrive. We’ll need to be ready by then.
