Comments on Pilot Study Report and Presentation <br />Obi ectives/Methods/Results/Conclusions <br />1. In the study plan, the two soil treatments in the primary study site are <br />described as rotocleared and non-rotocleared ("modified" and "normal" on <br />the study plan schematic). Our understanding was that both soil treatments <br />were to have been "direct haul" from the salvage area to the study site. <br />However, this apparently may not have been the case. In the study plot <br />layout included in the report, the soil treatments are labeled "fresh topsoil" <br />and "stored topsoil". Apparently, the rotocleared soil may have been direct <br />haul, but the non-rotocleared soil may have been stored in a short term <br />stockpile for some period of time, If this is the case, interpretations based on <br />the soil treatments wilt be complicated; since observed differences may be the <br />result of the different salvage techniques (rotocleared vs. non-rotocleared), or <br />they may be the result of differences in post-salvage handlmg (short term <br />stockpiling vs, direct haul), or some combination of treatment effects. In any <br />case, there were rather dramatic differences between the two soil treatments for <br />many of the attributes measured, and as such, it is important that the treatments be <br />fully defined. The methods and timing of soil salvage, length of storage and <br />approximate dimensions of storage piles, and timing and methods of transport, <br />placement, and final grading for each of the two soil treatments should be <br />described in detail in the Methods section of the report. <br />2. The study was properly expanded to incorporate growth and survival data <br />collection for non-irrigated root segment sprouts that developed on the two soil <br />treatments within the fenced primary study plot, as well as commercially grown <br />aspen seedlings that were planted in a nearby fenced area at Seneca II-W, and <br />natural sprouts located on a surface disturbance area at Yoast that had not been <br />mined. Additional documentation should be included in the report, regarding <br />certain aspects of the expanded study. Please amend the report to include: <br />A map or maps at appropriate scale to show the location of the <br />primary study site at Seneca II-W, the nearby fenced site at II-W, and <br />the monitored site at Yoast. <br />• A description of the soil treatment for the commercial seedling <br />planting site, as requested for the primary study site soil treatments. <br />• Details on potted nursery stock, including size of the transplants, <br />type/size of container, site origin of the seedling stock <br />(Forest/county/elevation, etc.), planting timing and method, and any <br />post-planting cultural practices (irrigation, weed control, etc.). <br />
