COLORADO S TAT E ~~ UNIVERSITY P.O.BOX 81 LA VETA, COLO. 81055 742-3588 cdorado scare forest serv~ce September 10, 1981 Jack Gillespie CF & I Steel Corp. Mining Department P. 0. Box 316 Puebla, Co 81002 Dear Mr. Gillespie: D '~''' 191 /!41M.!A1G DFO r4RTA~HvT I reviewed the Timber Resource Inventory Study made on C F&I lands near Stonewall in 1971 to determine timber production and timber resources for area involving the Allen and Maxwell mines. To the best of my knowledge, site indexs for timber stands in this area will vary from a low of 40 to a high of 65. In other words, these sites are producing an average of fourty cubic feet of wood fiber per acre per year. 41ith intensive forest management this production could be increased to sixty cubic feet or more. At the lower production levels, it takes over 100 years to produce trees • ~ of sawlog size. Mine props could be produced in 60 to 80 year rotations. Under intensive management, mine props could be produced in 40 years and sawlogs in 75 to 80 years. Using selective harvesting and management techniques, I estimate that 1500 board feet of sawlog material and 350 cubic feet of mine props could be cut per acre every 20-25 years from the timber stands that are on the property. At present stumpage prices for sawlogs and mine props this equates to a value of a little more than 380.00. On a per acre per year basis this will amount between 33 and $4. Without forest management, these figures would be considerably less. Not much is known about volume of timber harvested in the past. Evidence shows that area has been logged ,at least twice, once and late 1II00's and again sometime in eary 1900's. If you have any questions, please let me know. Sincerely yours, i ~V "~IL~ ~ ~l Clarence K. Morey District forester - ..- .~L. ~--~. -~ , ,.~;~" , ~`~~i
