My last post summarized research on current and historical pollinators and their role in robusta coffee fruit set in India, and I noted it was in recognition that this is Pollinator Week — an international celebration of the valuable ecosystem services provided by bees, birds, butterflies, bats and beetles.
I’ve summarized a couple of other papers on pollinators and coffee:
- Research: Shade coffee = more pollinators = higher fruit set (Pollinator diversity increases fruit production in Mexican coffee plantations: The importance of rustic management systems)
- Research: Shade coffee conserves bee diversity (Impacts of coffee agroforestry management on tropical bee communities)
These are by no means the only research done on pollination, pollinators, and coffee! Below I have listed many peer-reviewed papers specifically dealing with bees and coffee pollination, and often the role of preserving shade in and near the coffee farm to preserve the habitat of pollinators and improve the fruit set of the coffee and other crops on the farm. If you are especially interested in one of the papers and do not have academic access, please let me know and I can try to provide you with a copy.
Meanwhile, I also encourage everybody to head over the the website of the Pollinator Partnership, which sponsors Pollinator Week. They have every resource you can think of regarding pollination and pollinators — not just bees, but all the other insects and animals that perform this incredible service — and their conservation and status. New this year is a free app (iPhone or Android) called BeeSmart, a database of hundreds of North American native plants for attracting pollinators.
