Florida Keys / Dry Tortugas Regional CEM Available on MARES homepage as: strawman fkdt cem 5 dec 09.ppt
Florida Keys / Dry Tortugas Regional CEM • CEM objectives and approach to development • Existing related models • Overall structure of FK/DT CEM model • Responses – management activities • Sub-models • Defining characteristics and crtitical science needs
Objectives for MARES CEMs • Description of regional ecosystem • CEM elements • Defining characteristics of ecosystem (DPSIR Impacts) • Critical unknowns / science needs
Conceptual Ecological Models(Ogden et al. 2005) • Identify anthropogenic stressors, their ecological effects, and attributes useful in monitoring and forecasting ecosystem response. • Diagram qualitative explanations of how human activities alter ecology. • Tool for developing consensus and communicating working hypotheses. • Basis for specifying performance measures and developing monitoring and modeling activities to support restoration and management.
CEM Components • Major components: • Drivers: forces with large-scale influences on ecosystem • Stressors: physical or chemical changes caused by drivers within ecosystem • Ecological effects: physical, chemical and biological responses caused by the stressors • Attributes: parsimonious subset representative of overall conditions in ecosystem • Models depict general pathways by which large-scale drivers affect ecosystem attributes that are important to people. • External drivers create internal stressors creating ecological effects that lead to changes in ecosystem attributes.
DPSIR Framework Components Drivers: Socio-economic sectors that fulfill human needs and drive human activities, often leading to intentional or unintentional changes in ecosystems. Drivers are affected if changes are made to alter human activities for protection of ecosystems. Pressures: Human activities that exert positive or negative pressure on ecosystems. State: Status of the environmental (physical & chemical) and ecological (biological) components of the ecosystem. Physical, biological, and chemical processes interact to affect different structures (chemicals, species) that are measured by their attributes. Attributes are characteristics that contribute to ecosystem services. Environmental processes can also affect drivers and pressures, e.g. drought influencing agriculture or storm events influencing non-point source pollution. Impacts: Changes in the quality and functioning of the ecosystem have an impact on the welfare (well-being) of humans. Services are the benefits that ecosystems can provide, and their value depends on human need and use (e.g., market value). Services: Functions of the ecosystem that benefit humans in the short term or long term. Services depend on the attributes of the ecosystem. Value: The economic, cultural, or ecological value of the services. Values depend on the attributes of the state and characteristics of the drivers and pressures. For example, corals can provide shoreline protection, but the value depends on the frequency of hurricanes and the number of hotels/houses near the coast. Values, in turn, can affect the drivers and pressures. For example, fish biomass can sustain fisheries and influence ship-building. Response: Humans make decisions in response to perceived value. Ecosystem values are too often ignored in decisions because they are viewed as ‘free’. Ecosystem services should change perceptions of value and alter human responses, which can create changes in drivers and pressures.
