J <br />Sampling Methods <br />Cover. Cover will be measured by the point - intercept method. The point - intercept transect will be 50 <br />meters long with 100 points taken. <br />Production: Production data will be collected through use of the harvest method. All herbaceous <br />biomass produced during the current year within a vertical projection of the 0.5 sq.m. sample plot will <br />be harvested. Clipped material will be dried at 105 degrees C and weighed to the nearest 0.1 gm. <br />Resulting oven -dry weights will be presented as gm /0.5 sq.m. and lbs /ac. <br />Woody Plant Density: Woody plants rooted within 2 a 50 meter plots will be named by species. <br />Clonal species such as mountain snowberry will have nodes of more concentrated stem emergence <br />counted as individuals as was done during baseline surveys of woody plant density. <br />Species List. The species list will be developed from observations made during quantitative sampling <br />during the middle of the growing season. During years of bond release sampling, additional early <br />spring observations of the reclaimed area parcels involved will be made to fully document spring <br />• ephemeral species. <br />Species Density. A list of all species present within one meter to either side of the 50 meter cover <br />measurement transect will be compiled. The resulting number of species observed per 100 sq.m. will <br />be referred to as "Species Density." <br />Sampling Intensity <br />Because of the varying degree of disturbance or size of reclaimed areas from year to year, a <br />reclaimed sampling area size cannot be specified. Therefore, a minimum of one (1) sample for <br />each ten (10) acres of reclaimed area will be located in each block of reclamation or until <br />sample adequacy is achieved. Generally, at least 15 samples are collected unless the sampled <br />block is small. A particular block will be identified by year of seeding. Sampling locations will <br />generally be established through the use of random point selection. This method may be <br />modified when it becomes apparent that a more even distribution or allocation of sampling <br />points would be desirable, particularly if the reclamation block is split into a number of <br />subunits. Since the monitoring data are intended for evaluation of reclamation methods and <br />• performance of revegetation stands and not for strict statistical analysis, this "allocation" <br />method of sample point selection should be acceptable.
