U 4.~ - III IIIIIIIIIIIII III <br />• ~ 999 <br />STATE OF COLORADO <br />Roy Romer, Govei <br />DEPARTMENT OF NATURAL RESOURCES <br />MINED LAND RECLAMATION DIVISION <br />FRED R. BANTA, Director <br />DATE: December 6, 1989 <br />T0: H. Bruce Humphries, Minerals Supervisor <br />FROM: Daniel I. Hernandez, Reclamation Specialist <br />RE: Tree Replanting Success <br />Snyder Quarry Corrective Action Plans <br />Castle Concrete Company <br />MLRD File No. M-77-210 <br />Per Fred Banta's request, I contacted Chuck Kostecka, District Forester with <br />the Woodland Park office of the Colorado State Forest Service, on November 27, <br />1989. Mr. Kostecka and I discussed the tree species and size that would be <br />most advantageous to reclamation success for the Snyder Quarry access road <br />shoulders and the Williams Canyon disturbance. The following items were a <br />result of that discussion: <br />1. The success rate for full size ball-and-barlap Ponderosa Pine stock <br />transplanted at the quarry would be near zero. <br />2. Full-size trees need to be transplanted with a tree spade, which can <br />be used on only relatively level grades. The 2H:IY and 3H:IV slopes <br />along the access road shoulders and Williams Canyon disturbance are <br />too steep for the use of a tree spade. <br />3. Trees with the highest root-to-shoot ratios will have the best chances <br />for success. For Ponderosa Pine, the tree size that would best meet <br />this requirement would be seedlings to one-gallon containerized stock. <br />4. Success rates for Ponderosa Pine seedlings on steep slopes with little <br />topsoil and irrigation would be less than 10~. <br />5. For the most rapid establishment of an individual tree, the operator <br />would need to level out a three square-foot area, replace 6 to 8 <br />inches of topsoil (or, in the case of larger trees, enough topsoil to <br />cover the rootball), and install a drip irrigation system for 3 to 5 <br />years. Wood chips or landscape fabric could be used as a mulch for <br />moisture retention. <br />6. Douglas Fir seedlings would have a lower rate of success than <br />Ponderosa Pine seedlings as Douglas Fir is a shade-tolerant species <br />and develops during a second-cycle growth. <br />/lac <br />1964E <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel.
