There is an increasing need in assessing ecological quality and integrity of estuaries and lagoons. This chapter shows the most recent efforts in assessing individual biological elements (from phytoplankton to fishes), together with the integrative tools developed in different geographical areas worldwide. However, reducing complex information from multiple ecosystem elements to a single color or value is a substantial challenge to marine scientists, and requires the integration of different disciplines (chemists, engineers, biologists, ecologists, physics, managers, etc.), to reach agreement on the final assignment of ecological status. Hence, in the near future, emphasis needs to be directed at understanding the complexities of estuarine system functioning rather than simplifying and scaling down the system into smaller components.

“…This tool integrates the structures on the sediment surface, structures in the sediment, and the redox potential discontinuity (RPD) images. Therefore, the parameterization of sediment and animal features may be a useful combination to describe and assess habitat quality (Rhoads and Germano, 1986). This index attempts to show the usefulness of sediment profile imaging in demonstrating benthic habitat changes connected with physical disturbance, specifically with low oxygen concentrations (Nilsson and Rosenberg, 2000).…”

“…Therefore, instead of the earlier separation of the BHQ index into four successional stages, Rosenberg et al (2004) underpin the division into five classes in accordance to the WFD requirements (Table 1). According to the index authors, this scoring method can be valid for many boreal and temperate areas, as in these areas the benthic infauna is similarly structured and has a similar distribution and activity within the sediment (Pearson and Rosenberg, 1978;Rhoads and Germano, 1986). Despite sharing some principles, one main difference that distinguishes these two indices is that in the organism sediment index (OSI) (Rhoads and Germano, 1986; see Section 2.15) the successional stages are determined by examining the images by eye whereas in the BHQ index the different structures in the images are scored and their summary relates to a particular community stage (Nilsson and Rosenberg, 2000).…”

One advantage enumerated by the BHQ authors is the fact that a benthic quality assessment based on numerical scoring, as the one used in the BHQ index, allows statistical comparisons between strata and communities.…”
