This section outlines the methods by which development of the <br /> <br />. . " <br /> <br />compensatory wetland will be evaluated, and the long-term" success of the project assured. <br /> <br />Success criteria are the quantifiable physical, chemical, and ecological characteristics through <br />which the performance of a project will be measured. Generally, success criteria are not based <br />on direct measurements of ecological service, but are based on the measurement of <br />characteristics that are critical for the provision of ecological services. A constructed wetland <br />should provide the intended level of ecological service, when all the critical elements have been <br />provided. <br /> <br />The characteristics that are critical for long-term success of a constructed wetland are, <br /> <br />. Wetland hydrology, <br />· Percent cover of desirable hydrophytic vegetation, and, <br />· Control of undesirable vegetation. <br /> <br />When construction of the project is complete, these characteristics will be evaluated on a <br />prescribed schedule, using approved analytical methods, to determine when established <br />performance standards have been achieved. The performance standards established for this <br />project are short-term performance goals that, if met, will provide reasonable assurance of long- <br />term project success. If the constructed wetland meets the performance standards specified in <br />this plan during the prescribed monitoring period, it is reasonable to assume the wetland will <br />continue to provide a reasonable level of ecological service into the future. <br /> <br />This wetland project will be considered a success, and the project will be considered complete, <br />when all of the performance standards listed below have been achieved. <br /> <br />Benchmark Ecological Services, Inc. <br /> <br />May 2003 <br />
