Wow. Look, in order to substantiate claims about the decline or the upsurge of native pollinator populations, you would require a fair bit of field trials and studies. It is well known that the world of native pollinators is poorly researched. There is generally not enough money available.
Ironically, honeybees are the most researched insect in the world, I would think, because so much of our agriculture economies are dependent on them.
You referred to our web page on food for bees. That was largely designed to assist greater diversification, shall we say, and sustainability of local environments. I'm not talking about gardeners so much, but farm practices, reclamation projects and mines. Things of that kind are really all benefiting from a greater flow of diversity that provides food sources for native pollinators.
As well, in my outline that I provided in my speaking notes, I think it's important to recognize that one of the contributing causes to the decline of honeybees but also of many of the other pollinators is that if we really examine the landscape of North America, this has transformed drastically in the last 50 years.
From a great diversity of floral sources and undisturbed habitat, we have gone wild on producing all kinds of monoculture crops and on the removal of undisturbed habitat. We have failed to recognize as a society the intrinsic value of many of these habitats that contribute to sustaining wild pollinators, as well as other small creatures in this world—
