Could this be the Cause of Colony Collapse Disorder?

We have to give a hearty thank you to Tom Theobald, a Colorado beekeeper, who recently uncovered and exposed an EPA memo that could point to why bees are dying in such high numbers.

According to them memo, BayerCropScience is selling a seed treatment called clothianidin and it hasn’t done sufficient testing on the chemical to prove its safety for honeybees. It’s a systemic pesticide, meaning it’s absorbed into the plant, making all parts poisonous to insects that feed on it. It also makes me wonder what it does to us? It is mostly used on…you guessed it…corn. Actually 80% of corn seed is treated with it. When the corn tassels it produces a lot of pollen – pollen being a primary source of protein for bees. Beekeepers are seeing the biggest problems in their hives coinciding with the corn tasseling.

Top Bar Beekeeping

Tom working on a Top Bar Hive

This past weekend Tom and I took a class through the Institute of Urban Homesteading on Top Bar Beekeeping. The class was run by the founder of IUH, Ruby Blume, at her home in Oakland, California. Ruby has been using top bar hives for 15 years. She did use the more common Langstroth hives for 2 years and they just didn’t suit her so she now exclusively keeps 2 top bar hives in her urban backyard.

The first part of the class she discussed bees and beekeeping along with showing slides. The most experience we’ve had with bees is just doing minor maintenance work around the hives we’re hosting for someone else so we learned a TON of great information about bees, from their biology to their behavior to possible problems. Her knowledge on bees and beekeeping was amazing. It was also great to have another student there that was a professional beekeeper in France.

My favorite part, of course was interacting with the hives. The first hive was less active than the other hive, but it had a good amount of honey. The bees were pretty mellow and only got mildly irritated with us messing with them. The consensus was that the hive must have swarmed when Ruby was on vacation, which would explain why there seemed to be so few workers. Otherwise the colony was thriving.

The second hive wasn’t so happy. She had chalkbrood in it. Because of this stress, these bees were much more irritable and didn’t like us messing with them at all. She simply showed us the problems with that hive and how to check it and close it back up. Her philosophy with that hive is to just let it be. If it dies from the chalkbrood then they genetically weren’t strong enough to survive – definitely a more natural way of beekeeping where it’s survival of the fittest.

I would highly recommend this class for anyone that wants to learn more about top bar beekeeping or just beekeeping in general. A lot of the information we learned could be used for both styles.

And I just have to give a shout out to Yolanda who we met that is a regular reader. It was lovely meeting you!

Planning and Livestock

Michaela, the Urban Dirt Girl from Urban Dirt asked us:

What was the first thing you did when developing your land? Did you have a master plan or just chipped away at cultivating? Also, what animals did you decide to raise first? 

The posts were where the fence was located.

Great questions! When we moved into our home we had virtually a blank slate. Well, kinda. We had a lot of demolition to do including a very bizarrely placed fence and lots of dead or dying trees. Where the fence was located the ground also dropped off about 12-18″ though in the photo you can’t really tell.

Because I’m in landscape architecture I always make a plan first. We knew what we wanted – a large patio, vegetable beds, fruit trees, chicken coop, etc. But remember, if you ever go the route of a master plan, it doesn’t have to be set in stone.

Before we even closed escrow we went out and measured our entire property – front to back. With this I drafted up a plan. Originally our patio was going to be a more organic shape made up of tangential curves. However, we ended up deciding to have our wedding at our house and the patio that was planned wouldn’t accommodate it, so it changed into a rectilinear form. Form should always follow function.

Even though the masterplan was done, the priority was to dig the vegetable beds. In the SF Bay Area Spring comes fast in March and it was already January 1st. By January 18th demolition was done, most of our fruit trees were in and our 3 largest beds were dug. The 8′x8′ chicken coop and attached 8′x16′ run were next (which are long gone now btw). Then it was the patio. This past spring we planted more trees and dug two more beds. We also demolished the chicken coop and built a goat and chicken barn with a large run along the back fence. We will always have more work to do. Things will get torn down and moved. As you grow your needs and wants will always change, it’s inevitable.

When we moved in we already had chickens. They are of course the “gateway livestock” for urban farmers. We originally started with 3 hens that we had gotten from my coworker’s neighbor who had to move and needed a home for her chickens. My coworker took two and we took three. One died fairly early on and then another went broody so we got her 4 chicks. So when we moved here we already had 6 birds. We then got 7 more chicks. We lost one to coccidiosis and another one to sour crop. Now we have 23 birds with our new chicks. Once we got the chickens though, it seemed like expanding into other livestock was the natural way to go. The goats followed and then the rabbits. We are hosting 3 bee hives for someone but we’re now considering having our own topbar hives. We are also looking into doing turkeys next spring and Tom’s talking about pigs, though we’d probably keep them elsewhere.

Wow! I didn’t realize how much I just wrote! Well, thanks for asking! You can find out more about what we went through with our planning on today’s Homegrown.org blog where we are a monthly contributor!

Saturday’s Farm Diary – Bees

Bees flying in and out of their hive

As many of you know, bees are in trouble. In the last several years beekeepers have been noticing what has later been termed Colony Collapse Disorder (CCD). Colonies of bees just disappear with no sign, leaving juveniles and eggs in the hive. The most suspicious part is that other colonies and other insects and animals don’t move into the abandoned hive to raid it. Something is wrong with the hive, but what is it? Another thing that researchers are noticing is that the few bees that may be left in the hives are all suffering from every known bee virus simultaneously, which points at a complete immune system shutdown. In a previous blog I brought up that it could possibly be caused by genetically modified crops, so I’m not going to rehash everything here. Instead, I’m going to tell you how we, at Dog Island Farm, are trying to help and how you can help as well.

I’m a chronic researcher. I’ll research just about all I can before I do something…most of the time. In the instance of bees we kind of just dove right in. But it really wasn’t something I needed to research because we’re not actually caring for them. We’re just giving them a place to live. But while giving them a place to live it gives us a chance to learn about them while waiting for their honey. So how did we do this?

We had briefly thought about having bees but never thought about it seriously. Then one day while cruising the Farm and Garden section of Craigslist (something I’m rather addicted to doing) I came across an ad by a biology professor in Marin County who was looking for hosts for his hives. He breeds queens in the hopes of creating stronger, healthier bees that can resist CCD. While most of the places he was looking for were in Marin and Sonoma Counties, he also listed Vallejo.

I immediately emailed him and he responded. He said he liked Vallejo because it warmed up here faster in time for the Eucalyptus bloom. Hmmm, I don’t think I’ve ever had Eucalyptus honey. Within the next couple weeks he delivered an empty box with a stand. The stand was simple – just a wooden pallet with rebar legs. I learned a few things from him regarding setup.

1. A sunny spot with a little afternoon shade is ideal.
2. Place the legs of the stand in cans filled part way with oil to keep ants out.
3. Do what you can to keep tall grasses away from the stand – again to keep ants out. We did this by laying down black plastic and then a bed of river sand on top of that.
4. Make sure you don’t have skunks. Apparently they will raid a hive with no regard to stinging bees.
5. To attract bees you use a pheromone in the hive. A the time of setup though it was too cold so he didn’t add it.
6. They really don’t require much space at all. You want about 3′ clear on all sides of the stand to move around, but that’s about it.

Two boxes on the stand. New bees came in the box on the ground.

A couple of weeks later he showed back up with a second box, this time containing a colony that he had caught at a nearby property. He placed the box next to the empty one, put a shim in between the body and bottom board and out they came. The first few days they were a bit aggressive while they were trying to get their bearings. Not overly so, but while we were digging weeds out of the closest garden bed we spent a good amount of time running from them. Now they are just a bit curious, but mostly they just fly off to far away places to collect their bounty. They don’t stay in the yard as much anymore.

 This past weekend, the professor came back with a package of live bees that he had just bought. These were going to live in the empty hive. I watched in awe as he opened up the clear sided box and poured them onto the open box like water. They can’t fly when they are in a large mass, so they almost turn into a living liquid. The mound of bees on top of the hive oozed down between the bars like honey. He pulled a little tube out that contained the queen. One end of the tube is plugged with a piece of candy that the workers chew through to release her.

He’ll be back in a few weeks. I’m looking forward to learning more about beekeeping.
