SNELTON, Dlroctor <br />Richard D. Lamm <br />Governor <br />DATE: May 15, 1984 <br />T0: Brian Munson <br />FROM: Dan Mathews ~~~ <br />RE: 1984 Vegetation Inspection - "A" Team <br />At a vegetation task force meeting in February, 1984, it was decided that <br />quantitative vegetation sampling should be undertaken at a number of mines <br />this summer. Of the mines with which I most famil' here are only two <br />which should probably be considered - olow a Grassy Ga A number of <br />other "A" team mines in North Park, t e orthwest (HG, rapper, Sun), and the <br />Southeast may also be prime candidates. <br />Our rationale is that standardized sampling at a number of mines in each <br />region (i.e. same observer, same techniques) should allow valid comparisons of <br />the effect of various environmental factors (soil depth and quality, <br />precipitation, slope and aspect) and cultural practices (seed mix, season, <br />rate, mulch, cover crop, fertilizer, contour furrow act.). <br />~ Due to the time and expense involved in the collection and analysis of <br />\ production data, sampling will be limited to total cover and woody density. <br />`1~,~~,; Soil samples/depths and slope measurements will also be taken. In addition, <br />~(? sample specimens will be collected to develop an MLR herbarium. <br />D <br />Specific sampling plans for Colowyo~and Grassy Gap are listed below. I <br />believe Mike Savage has developed sampling plans for a number of other mines <br />in the regions I mentioned previously. <br />Equipment and Supplies <br />- 50m tape <br />- Field Data Forms <br />- Meter Stick <br />- Soil Auger and Sample Bottles <br />- Adhesive Tape - Felt Marker <br />- Point Frame <br />- Brunton Compass <br />- Hand Lens <br />- Plant Keys <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel.
