At this point, the value of production data from significantly grazed pastures, <br />such as the pasture in Photos 8 and 9 is questionable. The more productive lightly grazed or <br />ungrazed pasture/haylands such as the Morgan hayland south of the gravel road, the Tuttle Draw <br />pasture, the farmstead pasture/ltayland, and the Site 1 pasture should be sampled (or, for hayland, <br />first cut harvest production data should be provided). Map pazcels for which quantitative data is <br />not collected should be thoroughly described in zhe text of the application, with the justification <br />given for not collecting quantitative data. General management practices for the various parcels <br />in the expansion should be described, as well as specific current year management (presence or <br />absence of livestock grazing, timing and intensity; presence or absence of irrigation, timing of <br />application; plan for hay crop harvest, etc.). Pastureland should be sampled to adequacy for both <br />production and cover; hayland (if any truly exists) should be sampled soley for production, or first <br />cut harvest data provided. Due to variability uttong different fields, it might be most efficient to <br />sample the individual fields separately to adequary, or else group two or more fields with similar <br />apparent production and cover, but that is largely up to the discretion of the sampler, I would <br />recommend that the operator be asked to submit a specific sampling plan prior to initiation of <br />sampling. <br />The final sites we visited were the approved sagebrush reference area (Photo 17), and the treated <br />sagebrush area being tentatively considered for a dry pasture reference area (Photo 16). The <br />exact boundaries of the current reference area were not apparent to me, but the location appears <br />to be a shallow soil site on the top of a small mesa, dominated by big sagebrush with blue grams <br />and snakeweed the dominant understory components. There were small patches of more <br />productive herbaceous vegetation, dominated by galleta and needle-and-thread. The blue grams <br />had made minimal growth so far this spring. The treated sagebrush site would more closely <br />approximate the reclaimed dry pasture community, being dominated by introduced cool season <br />pasture grasses such as crested wheatgrass and Russian wildrye, with very sparse sagebrush. The <br />site had obviously been grazed by cattle earlier this season, and for this reason the value of data <br />collection from the site (particularly production data) would be questionable. It is also not known <br />whether the operator would be able to establish a reference area on this site over which they <br />would have the necessary management control. I believe I had indicated to Jim Irvine that Ite <br />should plan to sample both the existing reference area and the BLM reference area site this year <br />(ifofficially proposed), but I'm not sure what purpose would be served by sampling the grazed <br />BLM area this year. Sampling within the existing reference area would be to demonstrate that <br />reference area cover (which is the success standard for dry pasture) is equal'to or exceeds affected <br />area sagebrush community cover. I'll leave these reference area decisions up to you. In fact, 1'll <br />leave all the decisions regarding New Idorizon sampling and standards up to you. <br />Murari Shrestha asked that I send a copy of my memo to him, as well as to Jim Irvine, but I <br />declined. I told Murari that I would send my memo to you, and that you would be in contact with <br />him and with Irvine, and would probably send a letter with our recommendations. Not that I'm <br />trying to avoid getting any further involved in this, or anything. <br />cc: Larry Routten <br />I~ 004 <br /> <br /> <br />
