<br />UNITED STATES DEPARTMENT OF AGRICULTURE <br />SOIL CONSERVATION SERVICE <br />San Miguel County gravel pits - Page 2 <br />February 15, 1979 <br />Again this is more of a quarry-type operation, and I feel little can be <br />done with the side slopes. I have not noticed any soil material that <br />was set aside for surfacing. <br />Because of the snow cover, I was unable to make any estimate of the <br />present vegetation on any of the sites except Troy Rosec, fIowever <br />I am including a copy of the potential native vegetation for each of the sites. <br />In my opinion the Norwood airport and Egnar pits xould be similar to the <br />vegetation found under a Pinyon-Juniper Woodland aspect. The Basin pit <br />would reflect the lower extremes o£ the Loargy Foothill range site. <br />- Potential forage production would be somewhat lower than a typical <br />Loamy Foothills sits. Ttte Troy Rose pit xould be sinular vegetatively <br />to a Semi-Desert Loam range site in very low condition due to past <br />over-use. The Appl~:bauge pit could be classed as a Riverbottom <br />vegetative site. <br />In revegetation, gr~:ater success can be expected if the disturbed <br />areas are shaped an~9 graded, and covered with soil material to at least <br />a depth of 6 to 8 inches. We xould recommend late fall seeding on all <br />sites to take advantage of available spring moisture and less weed <br />competition. I recommend the following broadcast seeding rates for <br />mixtures: Egnar, Basin and Norwood airport sites -- Vinall Russian <br />wildrye - 6 pounds ;per acre; Nordan crested wheatgrass - 6 pounds per <br />acre; Amur intermedwate wheatgrass - ]1i pound:, per acre, Applebaugh site -- <br />Sodar streambank wheatgrass - 8 pounds per acre; Manchar smooth brome - <br />10 pounds per acre; Latar orchardgrass - 4 pounds per acre. Troy Rose site -- <br />Sand dropseed - $ pounds per acre; Paloma Indian ricegrass - 12 pounds per <br />acre. <br />I am also including a copy of a general soils map of the Dolores River <br />Basin for your use, I hope this information will be of help to you. <br />Sincerely, <br />Ch~~~ / <br />District Conservationist <br />Soil Conservation Service <br />iJorwood, Colorado <br />,, o <br />~. <br />
