Economic modeling of pollinator ecosystem services

We are developing a novel framework for quantifying the direct and indirect economic dependencies of the U.S. economy and industry sectors on insect-mediated pollination service.  Previous studies have only focused on the contributions of pollinators to agricultural yields, while our studies will also evaluate the cascading effects on associated industrial sectors (see pilot studies [1]).  The data and methods developed will be broadly applicable for evaluating the economic importance of pollination services to the world economy, as well as evaluating other ecosystem goods and services. The framework proposed in this work will help identify industrial sectors that are at most risks or likely to experience the most disruption arising from a reduction of pollination services. 

Recently, we have begun examining the role of pollination deficiency on declines in black cherry production in Pennsylvania.  Black cherry is a high value timber crop, but there have been significant declines in regeneration rates in the last ~20 years.  Together with Kelli Hoover (Penn State) we are investigating biotic and abiotic factors associated with these declines.
