Landscape effects on bee health  

Location can greatly impact the survival and health of honey bee colonies [1], diversity and abundance of wild pollinator species [2],  and pollination services of key crops [3].  We have recently initiated a new project to develop generalizable landscape indices – that can be applied to natural, agricultural, rural, suburban and urban landscapes – to map the quality of a landscape in terms of forage resource abundance, pesticide exposure risk, climatic severity, and population density of honey bees.  We have created a network of citizen scientist beekeepers to monitor the health and survival of bees in diverse landscapes and under different management regimes. Additionally, we are gathering data on abundance and diversity of wild bee communities in different regions.  Using this information, we will comprehensively assess the role of these indices in determining the health of managed honey bees and wild bee populations.  We are working with Azavea, a Philadelphia based company, to develop online tools which will both allow stakeholders to assess the quality of their landscapes for bees and provide recommendations for interventions that can improve bee survival and performance.
