issue. This concerns the area of species diversity and woody plant <br />density. <br />The success standards for species diversity at the Southfield Mine <br />is adequate when; the four dominant species, based on plant cover, <br />comprise no more than 80$ of the total species composition. No one <br />species shall comprise more than 40$ of the total species <br />composition as determined by plant cover. The author apparently has <br />a problem with this stating that baseline data was not taken into <br />account when developing this "arbitrary" standard. This may in fact <br />be partially correct. However, if baseline data was used one <br />specie(Blue grama) would need to account for over 50$ of the <br />reclaimed cover or maybe two warm season species would need to <br />account for 50+$ of the cover. This standard was probably created <br />with the understanding that the final species composition would <br />probably not reflect the baseline data given the seed mix approved. <br />In any case the operator would be deficient with their current data <br />since both dominant grasses are cool season species. The standard <br />in place is actually fairly lenient and allows more flexibility <br />than if we were to go strictly by the baseline data. The only <br />reason the author is questioning this standard is that one specie <br />(western wheatgrass) is nearly to the threshold limit of 40$ of the <br />total cover. This standard is very achievable and will provide for <br />a good permanent, diverse vegetative cover. If they insist on <br />revising this standard, I'm sure we could accommodate them but the <br />new standard will include a lot more warm season species, an area <br />where they are currently deficient. <br />The woody plant density success standard is also brought into <br />question in this report. The current standard is a bit unclear in <br />that a direct count of shrubs on the reclaimed area is to be <br />compared with a similar count on the reference area. The unclear <br />part is that a "t-test" would be utilized to evaluate data <br />equivalence. This is not necessary if all shrubs are being <br />counted(essentially a census).This section should be revised to <br />state that woody plant density will be successful if the woody <br />plant density on the reclaimed area is 90$ of the reference area, <br />or if true sampling is conducted it should be 90$ of the reference <br />area with 90$ statistical confidence. <br />There really should be no confusion about what is or is not <br />considered a woody plant. The Division's vegetation guideline <br />clearly states that subshrubs or half shrubs are not to be <br />included. The guideline specifically identifies Artemisia fridiga, <br />Artemisia ludoviciana, Ceratoides Janata, Xanthocephaluna <br />sarothrae, and Yucca glauca as half shrubs or (suffruticose) <br />species. All cactus should also be included in this group. None of <br />these are to be considered woody plants for the purpose of meeting <br />woody plant densities. Given this fact, woody plants were hardly <br />encountered during sampling. This should not present a problem <br />since success is based on reference area comparisons. <br />One point which should be mentioned is that Southfield has <br />committed to planting live seedlings at a rate of four trees and <br />
