4 - 57 <br />• The crown height of the first two individuals of each shrub species with a canopy <br />overlapping the transect line were measured to the nearest centimeter. Likewise the height and <br />DBH of the first two individuals of each tree species with canopies overlapping the transect line <br />were measured. DBH's were recorded to the nearest meter. Accuracy of tree height estimates <br />was improved through the occasional use of an Abney inclinometer, tape measure, and <br />geometry calculations. When the appropriate number of tree shrub species was not present <br />along the transect for measurement, those individual tree and shrub species nearest the <br />transect line were selected and measured. <br />Quadrats were used to collect density data. A rectangular quadrat 50 meters by 5 meters <br />was established along the cover transect. The number of mature (greater than 1.3 meters in <br />height) trees rooted within the quadrat recorded by species. A circular quadrat with a 2.5 <br />meter radius (19.6 m2 in area) was centered at the end of the line transect and shrubs counted <br />by species. A square quadrat 5 meters by 5 meters located at the end of the line transect was <br />used in the Juniper Woodland affected and reference areas. Shrub and tree data were analyzed <br />• statistically using the same OSM formula as ever for cover with density used for the mean. <br />4.5.6.3 COLLECTION AND ANALYSIS OF PRODUCTION DATA <br />Circular plots in one meter square in area were used for production estimates. The current <br />year's growth of all herbaceous plants was clipped. All graminoids were cut and sorted by <br />individual species while forts were combined into a single category. Each production plot <br />yielded on composite sample. <br />In the laboratory, clippings were over-dried at 105° for 24 hours and weighed to the nearest <br />tenth of a gram. Data were recorded as grams per square meter (g/mZ) and converted to <br />pounds per acre pb/ac) using the multiplier of 8.91. Statistical adequacy requirements for <br />production were calculated using the OSM formula above, except that mean production was <br />used in place of mean cover. <br />• <br />M~ Volume 1 4-29-96 <br />
