Changes in rangeland pricing method during the inflation-deflation price cycleUtah rangeland real estate underwent an inflation-deflation price cycle from 1975 through 1988. A total of 166 Utah land sales were analyzed to determine whether factors affecting rangeland prices changed during the price cycle. Regression analysis was used to test changes in method of pricing rangeland between the inflation phase (1975-81) and deflation phase (1982-87). The effects on sale price of parcel size (acres or hectares) and number of deeded animal unit months (AUMs) differed between the 2 time periods. Size of parcel sold significantly affected land price in the first time period, but not in the second. Conversely, the number of deeded AUMs did not significantly influence land price in the first time period, but did in the second. Thus rangeland tended to be priced per acre (hectare) during the inflation phase of the price cycle and per AUM of carrying capacity during the deflation phase. These results indicate that rangeland owners should try to maintain or improve range condition and carrying capacity to preserve real estate values during deflationary times.
Interactions of pinyon and juniper trees with tebuthiuron applications at 2 matched reinvaded sites in UtahTebuthiuron [N-[5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl]N,N'-dimethylurea] controls small trees in regrown pinyon-juniper woodland chainings. Precise applications by hand minimize cost and damage to forage plants. Little information exists on the applicability of local trials to varying Intermountain sites slated for reinvestment. We conducted 2 balanced factorial experiments at well-separated sites in the Great Basin and Colorado Plateau. Four rates (0.12, 0.25, 0.50, and 0.75 gm a.i. per 130 dm3 crown volume) of tebuthiuron boluses were applied to tree stembase, mid-crown, or dripline placements. Four size classes (12-99, 100-299, 300-599, and 600-1099 dm3 crown volume) of Utah juniper [Juniperus osteosperma (Torr.) Little] and single needle (Pinus monophylla Torr. and Frem.), and Rocky Mountain (P. edulis Engelm.) pinyon trees were treated in September 1985. Defoliation and mortality levels were estimated 24 and 36 months following treatments. Both sites received highly similar amounts of herbicide and cumulative precipitation. Analysis of variance showed that the presence and strength of main effects and first order interactions was largely site-specific. Pinyon was more susceptible than juniper at tither site. Medium-sized and large saplings were apparently more readily defoliated than seedlings and small saplings. Dosage effects were generally nonlinear for both species. The highest, most rapid and most uniform defoliation and mortality of trees resulted from application of tebuthiuron at the stem bases. This placement option has strong operational advantages and minimizes damage to forage plants beneath trees.
