  1. North point (red) N 150 ft 18o East Declination 15 ft Plot center (yellow) 15 ft 150 ft South point (red) Appendix A - PLOT DESIGN Plots are identified by three pins (24” steel rebar) with plastic caps set into the ground. Each pin has a GPS coordinate (UTM Zone 10T) and are identified by the plot number, irrigated or non-irrigated, and north and south indicators (the center pin has just the first two: e.g.. 7N = plot #7, non-irrigated center, 7NN = plot #7, non-irrigated north, 7NS = plot #7, non-irrigated south). Center pins have yellow caps and end pins have red (or orange) caps. Each plot consists of a center point and two 150 foot transects that are oriented north and south using 18o east declination. The transects begin 15 feet from the center pin and extend to the end pins. • Plots will be read annually, during the peak of the growing season when the plant community has fully developed for the year. Protocols measured annually: • Photo Points • Line Point Intercept • Canopy & Basal Gap • Production (Double Sampling) • Soil Aggregate Stability Test Plot center pin (24”) with cap in place

  2. Line posts (16 ft spacing) Heavy Duty Cattle Panel (3 @ 8 ft) Subplots (6 @ 1.92 ft2) Existing fenceline 6’ Steel ‘T’ posts (3 @ 8 ft spacing) Appendix B - EXCLOSURE DESIGN Exclosures are defined by three 8” cattle panels attached (wired) to 6 ft steel ‘T’ posts. A line post on the existing fence is used as the forth side of the exclosure. Most existing fences in the area have 16 ft spacing between posts so an additional steel post may be needed to anchor one of the panels. Exclosures will be read monthly using 1.92 ft2 clipping frames and gram scales. A new area in the exclosure will be clipped month and past clipping areas will be re-clipped. Green weights will be recorded in the field and paper bagged samples will be air-dried and weighed later to determine 1) air-dry weight in grams in each subplot, and 2) percent of air-dry material at time of clipping. Dry samples in an oven at 140o F for 24 hours or air-dry at room temperature for 72 hours to obtain air-dry weight (grams air-dry * 50 = lbs./acre). • Heavy Duty Cattle Panel • 16' x 52“ • (cut in half for 8’ sections) • 1/4" Rod Diameter • 2 3/4 Gauge Rod • 47 lbs.

Record top canopy, lower canopy layers, and soil surface or plant base using plant species codes (from USDA Plants Database www.Plants.usda.gov), lower canopy layer codes, and soil surface codes. Data is recorded in the Range Data Base software provided.

  4. Appendix C –PROTOCOL STANDARDS (page 2) Line Point Intercept Calculations [Range Database] • % Canopy Cover = [(total number of positions where Top Canopy is 'Real Plant Code')/(total number of positions completed)] * 100 • % Bare Ground = [(total number of positions where Top Canopy is 'None' AND Surface is 'S')/(total number of positions completed)] * 100 • % Basal Cover = [(total number of positions where Surface is 'Real Plant Code')/(total number of positions completed)] * 100. This calculation is also computed per species code in the same manner. • % Ground Cover Total = [(total number of positions where EITHER any Lower slot is 'L' or 'W' AND/OR Surface is NOT 'S')/(total number of positions completed)] * 100 • % Ground Cover Between Plant Canopy = [(total number of positions where Top Canopy is 'None' AND (any Lower slot has 'L' or 'W' AND/OR Surface is NOT 'S'))/(total number of positions completed)] * 100 • % Ground Cover Under Plant Canopy = [(total number of positions where Top Canopy is 'Real Plant Code' AND (any 'Lower' slot has 'L' or 'W' AND/OR Surface is NOT 'S'))/(total number of positions completed)] * 100 • % Total Litter = [(total number of positions where EITHER any Lower slot is 'L' or 'W' OR Surface is 'D' or 'EL')/(total number of positions completed)] * 100 • % Litter Between Plant Canopy = [(total number of positions where Top Canopy is 'None' AND (any Lower slot is 'L' or 'W' OR Surface is 'D' or 'EL'))/(total number of positions completed)] * 100 • % Litter Under Plant Canopy = [(total number of positions where Top Canopy is 'Real Plant Code' AND (any Lower slot is 'L' or 'W' OR Surface is 'D' or 'EL'))/(total number of positions completed)] * 100 • % All Plants = [(total number of positions where 'Real Plant Code' is 'Checked')/(total number of 'Real Plant Codes' entered)] * 100 • % Top Canopy Plants = [(total number of positions where Top Canopy is 'Real Plant Code' AND 'Checked')/(total number of positions where Top Canopy is 'Real Plant Code')] * 100 • % Top Canopy Points = [(total number of positions where Top Canopy is 'Checked')/(total number of Top Canopy positions completed)] * 100 • % Soil Surface = [(total number of positions where Surface is 'Checked')/(total number of Surface positions completed)] * 100 • Species Canopy Cover = [(total number of positions where Any Canopy Layer is 'Real Plant Code')/(total number of positions completed)] * 100
