So, why are honey bees such important pollinators?
From an ecological point of view there are at least 3 reasons:
Honeybees have evolved in tandem with certain flowers and they have adapted to facilitate each other;
One bee is able to rapidly communicate the location of a pollen/nectar source to the whole hive and an army sets out;
The bees then concentrate faithfully on that flower species until the pollen runs out or the nectar dries up, at which point the job of pollination is accomplished.
These features obviously make the honey bee important from an agricultural/commercial point of view. In addition, hives of bees are mobile and can be moved from crop to crop – an arrangement which can suit bees, farmers and beekeepers so long as everyone has a bit of respect. Wouldn’t that be great?
Certain species of Poplar are a valuable source of propolis for honey bees. The spring catkins may be visited for pollen and the spores of a parasitic rust fungus may be an alternative protein source in times when pollen is in short supply.
Poplars are a complex, wind-pollinated, pioneer tree species and they interbreed like mad; as a result they can be difficult to identify. There are many species world wide and several native to Europe. In addition, fast growing hybrid cultivars have been bred and these are much planted for timber. There is also interest in the fast growing varieties for short rotation coppice as a biomass crop.
One of my apiary sites is in a nature reserve on a small raised bog in Kildare. The clover and blackberry are in full bloom all around the fringes there so I expected to find the bees with brown or grey pollen loads. However, I was surprised to find them bringing in a lot of vivid orange pollen and no, that’s not propolis. Of course I’d come out without my camera so had to make do with my phone and these pictures don’t do the colour justice. Click photos to enlarge. Continue reading Poplar leaf rust spores?→
When beekeepers think heather, they think weather and ‘Will it ever stop bloody raining?’
Or you might wonder – ‘IS there a flow at all?’ Because often there isn’t and you can never tell in advance if it will or if it won’t. Heather honey is the most bewitching and frustrating of all honeys; if you can get a crop of sections or cut comb honey it’s close to heaven and so costly and disappointing when it fails.
