3.3 Validating Assessment Scores |
Graphs of the controlling factor and ecological function metric scores paired by reach suggest a slight correlation between impaired controlling factors and reduced ecological function (Figure B-72). In other words, when assessments suggest impairment of controlling factors within a particular shoreline reach (low score), habitat diversity and other indicators of ecological function (e.g., forage-fish spawning) are often reduced (low score). This relationship appears to be more pronounced in some geomorphic settings, such as low bank, marsh/lagoon, and spit/barrier/backshore habitats (Figures B-74, B-75, B-76), than in others (e.g., high bluffs; Figure B-73). Additional examination of reaches where this relationship does not hold may be useful for refining assessment techniques. As well, these graphical relationships only provide a first step at describing trends. Future efforts should use this information to design studies that address links between individual and cumulative impacts to specific ecological functions. More detailed analysis and discussion of this topic as it relates to prioritizing management actions is included in Appendix E.
