Each monitoring report will include: aj phato-documentation, b) estimates of percent vegetative cover, plant survival and undesirable species, c) wildlite usage, d) water quality and hydrology, site stability, and soils, and e) an overall qualitative assessment of project success for the wetland and buffer areas. The first monitoring report will serve as the baseline assessment report. If the performance criteria are met, annual monitoring will cease after the fifth year, unless objectives are met at an earlier date and the City accepts the mitigation project as successfully completed. 9.1 Vegetation Permanent vegetation sampling plots or transects will be established at selected locations within the mitigation area to incorporate all of the representative plant communities. The seme monitoring points will be re-visited each year, with a record kept of ali plant species found. Vegetation will be recorded on the basis of relative percent cover of the dominant species within the vegetative strata. All monitoring will be conducted by qualified Talasaea personnel. Locations will be established within the mitigation area from which photographs will be taken throughout the monitoring period. These photographs will document general appearance and relative changes wiihi: i the plant community. Review of the photos over time will provide a semi-quantitative representation of success of the planting plan. Vegetation sampling plot and photo-point locations will be submitted with the baseline assessment report. 9.2 Wildlife Birds, mammals, reptiles, amphibians, and invertebrates observed in the wetland and buffer areas (either by direct or indirect means) will be identified and recorded during scheduled monitoring events, and at any other times observations are made. Direct observations include 20 May 2003 364C-MitR p14(20May03).doc Talasaea Consultants, LLC PageB � 3�
