Permit Number: C1982057 Page 11 of 20 <br />Phase III <br /> <br />The Cedar Creek 2022 -2023 Report of Findings, Testing for Revegetation Success for Phase III Bond Release <br />submitted with the application describes the testing, methods used for sampling and provides the associated data <br />collected as illustrated in Table 1 below. The report also discusses each of the vegetation communities and their <br />sampling results in detail. <br /> <br /> Figure 1: From the CCAI 2022-2023 Report of Findings, <br />Testing for Revegetation Success for Phase III Bond Release <br /> <br />The following summarizes CCAI’s 2022-2023 Report of Findings, Testing for Revegetation Success for Phase <br />III Bond Release as per the data collection methods. <br />o Cover Sampling: Cover data was collected using a point-intercept method along 50-meter transects. A <br />total of 100 points were recorded for each transect, and data included interceptions with plant species, <br />litter, standing dead material, soil, or rock. Both first-hit and all-layer cover were calculated. <br />o Herbaceous Production Sampling: This involved clipping all herbaceous growth within 0.5-square- <br />meter circular plots. The clipped material was separated by lifeform (e.g., native perennial grasses, <br />introduced perennial forbs), oven-dried, and weighed. <br />o Woody Plant Density (WPD) Sampling: WPD sampling was conducted only in the reclaimed BRB-6 <br />All shrubs within 2m x 50m quadrats (100m2) were tallied by species and life stage. <br />o Plant Species Frequency and Density: During cover sampling, all plant species within one meter of <br />the transect were noted. This data was used to measure "species density," and indicates species <br />richness. <br /> <br />For performance standards and hypothesis testing a series of statistical tests were employed as per the Seneca <br />IIW Permit and DRMS regulations. These are presented below. <br /> <br />o Sample Adequacy: Was determined using a formula to calculate the minimum sample size required to <br />evaluate vegetation cover, production and woody plant density. If sample adequacy was not attained, <br />then the appropriate statistical test was used to evaluate revegetation success. <br />o Performance Standards: For cover and production, values were adjusted by excluding noxious weeds <br />and excessive annual/biennial species (more than 10% of relative cover or production).
