• 2.3 Production Sampling <br />The current year's growth of herbaceous plants sampled during peak of <br />green in July, was clipped from I meter square quadrats randomly located <br />along the 25 meter cover transect at each randomly located sample sites. <br />Plants were grouped in morphological classes for clipping and weighing. <br />Classes included: annual graminoids, perennial graminoids, annual and <br />biennial forbs and perennial forbs. <br />Clipped material was oven dried in a thermostatically controlled, <br />fan-ventilated oven for 24 hours and weighed to the nearest tenth of a <br />gram. Production is expressed by morphological class and by total <br />_ sample in grams/square meter, pounds/acre and kilograms/hectare. <br />2.4 Shrub Density Sampling <br />A quadrat system was used for sampling shrub density. A rectangular <br />• shaped quadrat 2 m by 25 rn was centered along the 25 m cover transect. <br />All shrubs ranted within the quadrat were tallied by species. Results <br />are expressed as the number of shrubs/50 square meters, number/acre and <br />number/hectare. <br />2.5 Collect and Identify Plant Species <br />During the course of field work, plants were collected, identified and <br />pressed. Specimens were submitted to Dr. William A 4;eber of the <br />University of Colorado Herbarium for verification. Based on these <br />collections and field observations, a species list was developed. The <br />status, native or introduced, is indicated. <br />Taxonomic nomenclature follows Weber and Johnston (1979). Nickerson et <br />al. (1976) and Beetle (1970) were consulted in an attempt to apply the <br />most widely utilized common names. Noxious weed designations follow <br />Thornton et al. (1974). Statements of origin follow b:eber and Johnston <br />• (1979). Voucher specimens are preserved in a reference collection. <br />3 <br /> <br />
