But there is a second option to find ways of creating more bee-friendly enviornment. There is another reseach group at the University of Reading, who are trying a very different approach. Scientists Vicky and Jenny Wickens are investigating a way to help bees thrive on the prime agricultural land, without affecting the way we farm.-So what we've got here?
-This is a soya flower strip. So these flower strips are putting, so they can boost the natural pollinators to this area. In fact, with bumblebees, we find 500 percent more bumblebees here than we do at grassy 1 field margins 2 in comparison.
They are conducting a trial at across 16 different farms. And where they planted these flower strips, they found the number of solitary 3 bees went up about a third and bumblebees increased fivefold.
-We see what bees get at. Then what's there for the farmer?
-They get improved yields. We have put proper plants in both the flower strips and in the field boundaries. They are just difficult grassy boundaries. And we are looking at the number of seeds that produced by plot plants. We found a 50 percent increase in the number of seeds in the flower strips rather than the field boundaries. And that just proves how important these flower strips are to the farmer.
So if successful, these flower strips could not only give bees a home in the countryside, they could actually increase the amount of food farmers can produce without changing the way they grow their crops.
But there is another potential solution in the pipeline 4. Reaching the long-term could be rather promising 5, although it is someway off. Lin Field is doing something which might make us less dependent on traditional pesticides 6. She's creating genetically 7 modified plants, which she believes could one day replace pesticides and help protect our bees.
