therefore disagree that Yellow sweetclover should be summarily <br />invalidated as being counted toward reclamation standards. <br />Finally, based on my (few) observations, it seems to me that <br />Yellow sweetclover is grazed by domestic animals and wildlife. I <br />would therefore submit that for reclaimed areas having a <br />postmining land use of rangeland or wildlife habitat, this <br />species would qualify toward the cover and production standards <br />in accordance with the phrase "or species that support the <br />approved postmining land use" (Rule 4.15.1(1)). <br />While the Division may have a valid concern that Yellow <br />sweetclover may exclude other species to the detriment of the <br />overall health of the reclaimed area, similar concerns were noted <br />regarding several perennial species on page 21 of the Division's <br />Vegetation Guidelines. No mention is made of the Division <br />disqualifying these species from applying toward the reclamation <br />standards. It is simply recommended that they "be used <br />cautiously, if at all,..." My feeling is that it would be <br />consistent with the above policy that Yellow sweetclover be dealt <br />with in a similar manner. <br />I have discussed this matter with Steve, though I do not <br />feel like we resolved this issue. At the risk of making a rather <br />small issue (molehill) into a mountain, I would ask that the VTF <br />consider this question again. I am not suggesting that all <br />biennials can be validly applied toward reclamation standards. I <br />am also not suggesting that yellow sweetclover should receive <br />equal status as perennial species just because this species <br />historically has been approved as a part of reclamation seed <br />mixes. But I am not comfortable with the idea that Rule <br />4.15.1(1) by default eliminates biennial species from reclamation <br />use. I would enjoy hearing you opinion on the matter as I <br />recognize that you are better versed in both the law itself and <br />its intent than I am. <br />2. Woody Plant Density - Sample Adequacy <br />At North Thompson Creek (1992), I sampled woody plant <br />density using both 50 and 100 square meter belt transects (see <br />North Thompson Creek Mine Site, 1992 Vegetation Report - page 5 <br />for methods, page 7 for results, page 8 for sample adequacy <br />implications, and Tables 6, 7, and 8 for data). As we discussed <br />on the phone, a simple increase in the plot size does not <br />necessarily lead to a decrease in the sampling effort, or even in <br />a decrease in the statistical adequacy calculation. Obviously 16 <br />samples are not the basis for final conclusions even for this <br />particular site. Even so, it is interesting to note that after <br />16 50 meter squared quadrats, the sample adequacy number was 287. <br />After 16 100 meter squared quadrats, the sample adequacy number <br />was 346. <br />
