Changes in bee habitat floral composition shape the available nutritional supply in the environment. In this context, the key plant species must be present in the flora to produce pollen that is nutritionally balanced for bees. Lack of nutritionally balanced food results in limitation posed on the growth and development of bees, negatively influencing their populations. Improved understanding of impacts of taxonomically diverse floral resources on bees is needed for better understanding of pollinator decline and may result in more successful intervention strategies.
