Black Bears Strike But Are Repelled By Electric Fences In Ontario Beeyards

Some black bears did launch an attack on of our remote beeyards last week! 

This is what bear damage looks like, and it could have been a lot worse. The total loss was only four frames of brood. And that's because this beeyard, like all of our locations in southern Ontario, is protected by a heavy duty solar fencer.

Its unlikely the hive blew over in the wind - in the time that has passed since we last visited this location there hasnt been any extreme weather. But if it was upset by bears, then how did they manage to get over the fence? 

I have come to believe that a momma bear somehow managed to leap the perimeter - once. She then got the biggest electric shock of her life, and ran way back into the woods to recuperate.

The fence is only two strands of wire but they are electrified to 12 volts by a solar panel charged capacitor mechanism.  Its snaps when its at full strength. The animal must have felt the shock at least once, for it did no real damage except to knock over one beehive,

I reckon as soon as the bear got shocked on the fence it ran away bawling back into the woods. In my crime scene reconstruction I have a second perpetrator, and perhaps even a third involved in this ‘break and enter’ heist and murder of bees. 

These accomplices had the presence of mind to stay at the site and capitalize on what the first bear had achieved before they too were shocked and gave up trying to get more grub. They successfully pulled four wax frames of brood, which is what beekeepers call the queen bee’s eggs, out of the spilled container. They did manage to get four whole frames under the electrically charged wires before they too must have been shocked, and ran away back into the woods. I say that because no bear would leave that good food unless seriously deterred by electricity. When we checked the fence we found the it was giving a very high charge of 12.2 volts!

The bears eat everything except the wood. They love the brood frames more than the honey frames and these are very nutritious and tasty especially when covered with honeybees! You can see some of the wooded splinters beside the box. They left a train of these wood frame splinters for twenty feet back into the woods. There was one collection of six or more splinters stacked near a big tree trunk which is where at least one of the animals enjoyed a tasty meal in private away from the fence and his friends.

Make Every Acre Count with the BCRC's New Gross Margins Calculator

Gross margin analysis can be used to evaluate the financial performance of various enterprises of a farm business within the short term. This analysis can assist in allocating limited resources (like land) to their existing enterprises to find which combination optimizes profit.   If a beef cattle producer has land allocated to specific uses (e.g., pasture, crops), the reallocation of this land has implications for the farm’s net income. For example, cow-calf producers must choose between maintaining pasture and hay land or converting it into cash crop production. These decisions are driven by ecological considerations (e.g., risk of erosion, too rocky), personal preference and the potential profitability of each land use. Gross margin is the total revenue derived from an enterprise less the variable (direct) costs incurred in that enterprise (e.g., feed, fuel, seed). This can be reported for the whole enterprise or per unit of output. For example, land allocation can be considered o

The Unexpected Upside of Canada’s Wildfires

Colin Penner, who farms about 3,700 acres an hour's drive north of the U.S. border, crunched up a handful of plump canola pods and blew the chaff into a stiff prairie breeze. A small pile of tiny black seeds remained in his palm. Last summer, high heat and harsh sun scorched canola's yellow flowers and ruined their pollen, knocking down yields across Western Canada. This summer, smoke from nearby wildfires shrouded the July skies and protected Penner's young crop from the sun's burning rays, resulting in more seeds per pod and more pods per plant. RELATED: Should Canada sprint to replant trees after intense wildfire years? "Look at all these pods," he said. He would wait to see what the harvest brings, but "smoke will likely be a positive thing." Protection from extreme heat As Canada's western provinces experience the second-worst wildfire season in decades, driven by hotter and drier conditions due to climate change, some canola farmers say they are seeing an unexpected benefit
