Woody Plant Density. The density of shrubs and trees by species per unit area will be estimated. Shrub • <br />and tree establishment areas will be delineated and sampled separately from the general reclaimed units. <br />Values will be presented as #/plot, #/ac and #/ha. <br />Species List. A list of all species observed during sampling will be developed. Common names will be <br />included, as will life form, origin, and longevity. The initial species list will be upgraded in subsequent <br />monitoring efforts. <br />Sampling Methodologies. <br />Cover. Cover will be measured by the point-intercept method. The point-intercept transect will be at least <br />25 meters long with a minimum of 50 points taken. <br />Production. Production data will be collected by the harvest method. All herbaceous vegetation occurring <br />wRhin the vertical projection of a 1Y2 m2 to 1 m2 plot will be harvested as discussed in Sampling <br />Parameters. <br />Woody PIaM Density. Woody plant densities will be measured in a 1 m x 50 m (50 m2) quadrant in the • <br />reference area and generally a 2 m x 50 m (100 m2) quadrant in the revegetated areas. Larger or smaller <br />quadrants may be used in reclaimed areas depending on area to be sampled or specific sampling goals. <br />Species List. The species list will be developed both from spring flora investigations and from information <br />gathered during peak growing season sampling. <br />Samolino Intensity. Because of the varying degree of disturbance or size of reclaimed areas from year to <br />year, a size dimension of a recaimed area 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 sample adequacy <br />(if required) is achieved. 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 modified when it <br />becomes apparent that a more even distribution or allocation of sampling points would be desirable, <br />particularly'rf the reclamation block is split into a number of subunits. Since the monitoring data is intended <br />for evaluation of revegetation stands and recamation methods and not for strict statistical analysis, this <br />"allocation" method of sample point selection is practical. A sampling point is that location in the study area <br />where the production, cover and woody plant density measurements for a sample are collected. • <br />13-30 Revised 0/15/93 <br />
