Pollinators provide a key ecosystem service vital to the maintenance of both wild and agricultural plant communities. In 1999 the Convention on Biological Diversity issued the São Paulo Declaration on Pollinators, recognizing the critical role that these species play in supporting and maintaining terrestrial productivity as well as the survival challenges they face due to anthropogenic change. Today pollinators are considered to be in a state of decline;
Wild pollinators often visit many plant species and plants are visited by many pollinator species. All these relations together form a network of interactions between plants and pollinators. Surprising similarities were found in the structure of networks consisting out of the interactions between plants and pollinators. This structure was found to be similar in very different ecosystems on different continents, consisting of entirely different species. Bees are the most numerous, effective, and important pollinators. They pollinate both our crops and wild plants, providing us with one-third of the food we eat and allowing wild plants to reproduce and produce the berries, fruits, seeds, and other plant foods that form the base of the natural food web. The domesticated honey bee pollinates the vast majority of agricultural crops.
At the same time, roughly 4,000 species of native bees—some of which are endangered—perform the critically important ecological service of pollinating wild plants across all North American ecosystems. Many bees are generalists, but some species are specialized pollinators that require specific host plants to survive. Without healthy habitat, wild bee populations decline and our ecosystems weaken.Bee communities, both wild and managed, have been declining over the last half century as pesticide use in agricultural and urban areas increased. Changes in land use have resulted in a patchy distribution of food and nesting resources. Concerned bee researchers recently met to discuss the current pollinator status in North America and to publish a report about it. Since January (2007), there have been a number of reports in the media about the mysterious disappearance of large numbers of honey bees called colony collapse disorder. This has many growers concerned about how they will continue to be able to pollinate their crops. Now more than ever, it is critical to consider practices that will benefit pollinators by providing habitats free of pesticides, full of nectar and pollen resources, and with ample potential nesting resources.
