The Colorado Division of Wildlife (CDOW) has reviewed a revised <br />submittal including a revised Revegetation Plan and a research proposal from Dr. Wayne Shepperd from <br />the Rocky Mountain Reseazch Station. CDOW personnel met with Seneca, Division of Minerals aiid <br />Geology (DMG), and Dr. Wayne Shepperd in September to discuss options for habitat treatments (e:g: <br />prescribed burning) to improve remaining aspen stands on Seneca property. After the field visit; .. ',. <br />everyone agreed that habitat treatments were not likely to be effective and that experimental research on; <br />techniques to reestablish aspen on reclaimed mined lands would be more beneficial. Efforts to <br />reestablish aspen are valuable because aspen communities provide important wildlife habitat. The <br />Seneca's logistical and financial support of this project is a step towazds improving our understanding of <br />aspen reestablishment. <br />We have reviewed the proposal from Dt. Shepperd and anticipate that it will provide insight into how to <br />best use drip imgation to transplant aspen, thus making a lasting contribution to aspen reestablishment <br />on reclaimed mine lands. CDO W does, however, have a few suggestions concerning the experimental <br />design. First, the proposal does not include a control plot where no supplemental water is delivered. We <br />believe that a control plot would strengthen the findings of this reseazch. We also think that it would be <br />useful to collect more detailed soil information in addition.to collecting the soil moisture within the <br />rooting zone. For example, it would be interesting to measure and compaze the soil moisture/soil <br />structure of the soil in the imgated plots to soil measurements taken at anon-irrigated control plot and at <br />a nearby native stand. One of our principle concerns has been that surface disturbance during mining <br />changes the soil structure and soil hydrology, which in turn will affect whether aspen clones, will survive <br />past the completion of the supplemental imgation. Detailed soil information might provide insight into <br />this question. <br />Finally, using centimeters as the unit of measurement will be meaningful for some of the tree <br />DEPARTMENT OF NATURAL RESOURCES, Greg E.
