Ecosystem Services Decisions require consideration of how the final action contributes to more sustainable systems of production and consumption.  As such they rely on the integration of scientific data, stakeholder inputs, cumulative impact assessments and Trade Study Analysis.  All of these sources are characterized by uncertainty where the available information is imprecise, incomplete, conflicting and changing with time.  The Ecosystem Services Decision making process, based on this “wicked” information needs to develop metrics that not only indicate the satisfaction with cumulative impacts, gains and losses and associated tradeoffs, but also helps build stakeholder buy-in, and guides future research, management and monitoring efforts associated with sustaining ecosystem services and benefits.

Ullman recently lead a team in the development of BASS, Bayesian Analysis for Spatial Siting.  BASS is an Ecosystem Services Decision support tool that provides a robust, quantifiable decision support system to integrate disparate bio geophysical, social, and infrastructure information and associated uncertainties in an explicit way to assist decision makers with site evaluations of future ocean renewable energy projects. Further, BASS is a spatial planning tool that captures, shares, and compares ideas from stakeholders, proposal proponents, and decision makers, helping them to understand the resource implications of different management alternatives and reveal tradeoffs among management alternatives.
