Twenty Mile Mine Amendment - Baseline Vegetation Study Plan <br />Sample points may be rejected in the field for several reasons. This includes previously <br />unmapped surface disturbance, excluded soil types (porcelainite, sand blow outs, etc.), or <br />unmapped vegetation community inclusions. Reasons for sample point rejection will be recorded <br />in the field and documented in the baseline vegetation report. When a sample point is rejected, <br />the next randomly generated sample point will be used in its place. <br />Figure I: Random Sample Point Locations Grid <br />Sampled Vegetation Community <br />Intersection excluded from random <br />sample point set due to proximity to <br />vegetation community boundary. <br />Fixed Reference Point <br />Random "X" offset <br />I <br />I <br />Random "Y" <br />offset <br />Grid intersections are randomly selected for sample point order. <br />2.3 Transect Orientation <br />Each sample transect will be oriented in a randomly generated compass direction. One of two <br />locations will be used as the transect start point depending upon whether or not a vegetation <br />production sample enclosure is in place at the sample start point. When a production sample <br />enclosure is not used, transacts will start at the designated sample point. When a production <br />sample enclosure is used, transects will start from the edge of the enclosure. <br />Should a sample transect exit the vegetation community, it will be redirected from the point of <br />exit at a 90 degree angle to the original heading back into the sampled community. Also. when <br />transects intersect a non-vegetated area (i.e. rock pile, road, rip-rap, etc.). they will be redirected <br />back into the vegetation community at a 90 degree angle to the original bearing.
