3.0 RESULTS <br />The reclaimed area which is the subject of this bond release application was revegetated prior to <br />1991 and its subsequent history has been documented in the approved reclamation plan and annual <br />reports submitted to the DMG over the years and is not presented again in this document. To facllftate an <br />evaluation of revegetation success, comparison has been made with parameters from the approved <br />reference area and / or standards as appropriate. <br />Vegetation data colleded utilizing accepted scient'rfic means and statistical analyses from both the <br />reclaimed area (Plates 1 - 8) as well as that collected from the extended reference area (Plates 9 & 10) <br />during 2000 have been organized, summarized, and presented on a variety of tables and charts in <br />Appendix TC. Plates 1 - 10 are presented in Appendix TC as well. <br />3.1 General <br />Review of the summary data and comparisons presented on Table RS 1 indicates that the <br />Applicant's revegetation efforts for the North Thompson Creek Mines have passed all applicable <br />comparisons in accordance with Rule 3.03. Release of Performance Bonds as well as those of the <br />promulgated Vegetation Guidelines (April 18. 1995). Therefore. the North Thompson Creek Mines meets <br />all of the vegetation criteria for release of Phase II bonds and Phase III bonds for the first year (2000) of <br />the two-year evaluation. <br />3.2 Grtwnd Cover <br />Evaluation of the ground cover variable in accordance wRh Rules 3.03 and 4.15 utilizing the <br />approved testing protocols detailed above results in a positive finding regarding the 2000 sampling data <br />sets. In this regard, review of the first portion of Table RS 1 indicates that the mean perennial ground <br />cover of the reclaimed area substantially exceeds 90% of the analogous value for the extended reference <br />area in 2000. The revegetated area mean (45.56% cover) is far greater than 90% of the value of the <br />extended reference area (27.12%). This Tending is validated statistically using the one-sample reverse <br />null hypothesis test. The derision rules for this test were: <br />If C s t l,a ~., d,.l, conclude failure to meet the performance standard, and <br />If Y > t I,q;~_,,, I, conclude that the performance standard was met (for a = 0.1 ). <br />Q:IB®dB Q~1®S .97[16p, wc.
