From the Introduction Paper: Interest is increasing within the U.S. Army Corps of Engineers (USACE) in developing approaches appropriate to the management and restoration of aquatic and terrestrial ecosystems under the jurisdiction of Corps Districts and Divisions and located on Department of Defense (DoD) lands. Development and application of ecosystem management and restoration initiatives will require the USACE to develop improved ecological modeling capabilities, and associated assessment tools and approaches, that go beyond current capabilities in water quality and contaminant modeling. New modeling skills and specific models will be required in order to project and assess impacts of Corps activities and functions and related human actions on aquatic and terrestrial ecosystems, and their constituent biota and ecological processes, at multiple organizational levels and scales of space and time. To further the development of expanded ecological modeling capabilities relevant to the Corps’ ecosystem management and environmental stewardship missions, a workshop was organized and convened to identify and discuss promising and appropriate approaches to ecosystem modeling and assessment for application within the USACE. The workshop brought together scientists from the Waterways Experiment Station (WES) involved in ecological assessment and modeling projects, with scientists having extensive experience with diverse approaches to ecological modeling from universities, other federal agencies and national laboratories, and private consulting firms. The workshop was designed to be highly interactive, with short, focused presentations on specific topics by both WES and outside speakers, followed by extended time for discussing issues raised pertinent to the proposed new modeling initiative. While the eventual goal of the work that will follow from this workshop is to develop broad ecosystem modeling and assessment capabilities useful in many potential applications, this work will be initiated by a “test case application” focused on evaluating aquatic ecosystem level impacts of zebra mussels at Corps projects. Zebra mussel impacts on water quality conditions, aquatic food webs and trophic dynamics, and other biotic species (e.g., native unionid mussels, phyto- and zooplankton, fish) are of interest in this work, and provide the organizing conceptual basis for the proposed initial modeling activities. The desired modeling approaches that emerge from the workshop should go beyond current water quality and contaminant modeling capabilities; should be capable of being run in some applications coupled to existing water quality/contaminant models; and should include capabilities for modeling zebra mussel and other invertebrate (e.g., filter feeding zooplankton species) and fish populations (both planktivorous and piscivorous species) at broader spatial scales and levels of ecological organization than are captured in current models. To provide background for proposed modeling activities, workshop presentations were designed to review information on existing approaches to ecosystem modeling and assessment for aquatic and terrestrial environments, along with information on the biology and ecology of zebra mussels and their impacts (water quality, trophic dynamics, biotic composition) on aquatic ecosystems at Corps projects, and on possible linkages to existing capabilities in hydrodynamic and water quality modeling. This new ecosystem modeling initiative is being conducted as a joint effort among several specific WES work units in the Common High Performance Computing Software Support Initiative (CHSSI), the Zebra Mussel Control Research Program (ZMRP), and the Ecosystem Management and Restoration Research Program (EMRRP). The coordinated effort is managed through the WES Ecosystem Modeling Institute (EMI). Prior to the workshop, each participant and speaker received a packet of background materials that clearly explained the organization, rationale, purpose, and expected outcomes of the workshop; the sequence of topics included in the workshop agenda; and the expected outcomes and topics of the focused discussion sessions held during the course of the workshop. Each workshop speaker also received detailed guidance on their “assigned” topic and its relation to the overall workshop objectives.
