<br />• ice cover, yet WET assumes that other physical factors are more important in determining <br />habitat suitability ratings than is accessibility. The seasonal use patterns of the indicator <br />avian species document that of the 19 species known to utilize this region, 76 are nesters <br />or migrants which possess Moderate and Low Ratings, respectively, while only three <br />species are potential winter occupants. However, this use category possesses a High <br />habitat rating. The WET assumptions appear flawed with respect to wildlife utilization <br />ratings. The overall Wildlife Diversity/Abundance Rating of High is also difficult to fully <br />understand. Examination of the WET Manual reveals that Keys exist for Wildlife Breeding, <br />Migration and Wintering, but the assumptions used to derive this value are seemingly <br />missing. Therefore, upon excluding the obvious earlier rating associated with Wintering, <br />these categories generally possess ratings of Low to Moderate, while the overall <br />importance of the site is High with respect to Wildlife Diversity/Abundance. It is believed <br />that this rating is exaggerated for the same reasons described for wintering habitat. <br />SUMMARY <br />Although this evaluation suggests that limitations exist with respect to certain <br />assumptions used in the WET Methodology, in most areas, the major functional values <br />of these wetlands as identified by professional experience and opinion are verified using <br />this model. This conclusion appears most .valid regarding the hydrologic values of these <br />wetland areas. Specifically, while the Effectiveness and Opportunity categories of the <br />• evaluation for most hydrologic areas possess a High probability rating, the overall Social <br />Significance probability ratings are Low to Moderate, meaning that according to the WET <br />Manual this site possesses somewhat limited values with respect to economic value or <br />strategic location. An apparent interpretation of such results suggests that although these <br />wetlands are valuable in contributing to the overall environmental balance of the area, <br />these wetlands types do not appear to be limited with respect to their distribution or <br />functional efficiency. <br />Since this project may ultimately require a 404 permit application, it is believed that <br />this is the most significant finding of this evaluation. This finding suggests that although <br />the Effectiveness and Opportunity functions of this wetland are higher than the Social <br />Significance functions, it appears possible that the site can be developed without <br />adversely influencing the environmental values associated with the wetlands in this area. <br />As such, it appears that it will be possible to facilitate mining of the site wherein the <br />hydrologic functions associated with the Effectiveness and Opportunity categories are <br />preserved by designing a sound reclamation plan. <br />• <br />
