[Editor's Note: With this article, we welcome our new Viticulturist Jordan Lonborg to the Tablas Creek blog. He joined us in February and will be leading our vineyard team and our biodynamic program, including a new beehive program that he describes below.]
Every March, as flowers start to bloom, honeybees that have successfully overwintered begin the foraging process. The bees start to collect tree resin or propolis which is used to strengthen hives structurally; pollen, which is converted to protein;and flower nectar, which is converted to carbohydrate (honey). The honey and pollen are essential food sources and determine the strength and size of the colony. On years that we receive enough rainfall for a strong wildflower bloom, another process takes place. The phenomenon known as swarming.
Honeybees are a fascinating species. It is this process that fascinates me the most. In early spring, when wildflower nectar flow is at its peak, the workers are able to sense that the queen that overwintered with them starts to lay fewer eggs. In response, the workers then start to build queen cells within the hive. These cells are not your typical hexagonal shape we are so used to seeing. A queen cell is a cone-like structure that is built vertically through the hexagonal worker cells. Once the queen deposits eggs into the queen cells, the colony starts making preparations to split the hive. Scout bees begin to search for a suitable location for a new hive site. The scouts have been known to search up to 30 miles away from the hive in search of a new hive site. This is where the bee keeper (read: yours truly) steps in and encourages these bees to make their new home in a place where they can help us.
Swarm catchers come in all shapes and sizes. There are three essential characteristics that successful swarm catchers will share. First, there will be a secure cavity with one entrance. Second, they will have a piece of pre-existing honey comb that you obtain from either one of your previous hives or from another reluctant beekeeper in your area. Lastly, a small vial containing honeybee pheromone to attract the bees to the catcher itself. Here at Tablas, we used 16” compressed flower pots that were mounted to a square piece of plywood. Three of the four drain holes were plugged with foam insulation. We then hung these swarm catchers strategically (near plants that are blooming and close to a water source) anywhere from 6’-16’ off the ground. An example:
Then, you wait. It could be anywhere from a couple of weeks to a couple of hours until you catch a swarm, but when you do, you know, and it’s exhilarating.
Swarms can contain anywhere up to 10,000 to 40,000 bees. When they select the swarm catcher as a suitable hive location, a literal cloud of bees surrounds the catcher until the queen either lands on the catcher or in the catcher, and the rest of the colony follows. As an observer, the bees are fairly docile at this point, fully engorged with honey, and with a one track mind. Those who are daring enough can walk into the middle of this cloud and experience something few have. It is one of the rare times you can work with bees with no real fear of getting stung. Once all bees have entered the catcher, preparations are to be made for the hiving of your newly caught swarm either that evening or the following morning. Another close-up view:
So far, this year at Tablas Creek Vineyard, we have captured 3 swarms, and successfully hived all of them. We started the bee project for a few reasons. For one, it is in line with the bio-dynamic and organic practices we follow here on the property. Also, it is important that we enhance the biodiversity at Tablas Creek any way we can. Whether it is planting fruit trees throughout the vineyard, incorporating animals into our farming practices, or, keeping bees to help pollinate our cover crops, a biodiverse farm is a healthy one. Lastly, without honey bees, the human race would cease to exist. I guess you could say we are just doing our part to ensure the continuation of one of the most important species on the planet.
