2 <br />g/m lbs/ac, and kg/ha. <br />woody Plant Density. The density of shrubs and trees by species per unit area will be <br />estimated. Shrub and tree establishment areas will be delineated and sampled separately <br />from the general reclaimed units. Values will be presentetl as #/plot, #/ac and #/ha. <br />Species List. A list of all species observed during sampling will be developed. Common <br />names will be included, as will life form, origin, and longevity. The initial species list <br />will be upgraded in subsequent monitoring efforts. <br />Sampling Methodologies. <br />Cover. Cover will be measured by the point-interc apt method. The point-intercept <br />transact will be at least 25 meters long with a minimum of 50 points taken. <br /> Production. Production data will be collected by the harvest method. All herbaceous <br /> 2 2 <br /> vegetation occurring within the vertical projection of a 7/2 m to 7 m plot will be <br /> harvested as discussed in Sampling Parameters. <br /> 2 <br /> woody Plant Density. woody plant densities will be measured in a 1 m x 50 m (50 m <br />) <br /> 2 <br /> quadrat in the reference area and generally a 2 m x 50 m (100 m ) quadrat in the <br /> revegetated areas. Larger or smaller quadrats may be used in reclaimed areas depending on <br /> area to be sampled or specific sampling goals. <br />Species List. The species list will be developed both from spring flora investigations <br />and from information gathered during peak groui ng season sampling. <br />Sampling Intensity. Because of the varying degree of disturbance or size of reclaimed <br />areas from year to year, a size dimension of a reclaimed area cannot be specified. <br />Therefore, a minimum of one (t) sample for each ten (10) acres of reclaimed area will be <br />located in each block of reclamation or until sample adequacy (if required) is achieved. <br />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.
