J <br />Sampling Methods <br />Covet. 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 yeaz 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 spedes. <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 />Speces List. The species list will be developed from observations made doting quantitative sampling <br />during the middle of the growing season. During years of bond release sampling, additional early <br />spring observations of the reclaimed azea parcels invoh+ed 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 rtansect will be compiled. The resulting number of speces 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 azeas from year to year, a <br />reclaimed sampling area size cannot be specified. Therefore, a minimum of one (1) sample for <br />each tea (10) acres of reclaimed azea 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 pazticulaz block will be identified by yeaz 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, pazticularly if the reclamation block is split into a number of <br />subunits. Since the monitoring data aze 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. A sampling point is that location in <br />PR-02 31 Revised 01/D6 <br />
