FRO Resources In each of the 20 or more belts sampled, shrubs along the central • intercept line (Figure 1) were measured to obtain canopy cover by species. Actual density counts were made by species in the entire 4m X 10m belt (including those plants occurring along the intercept line). Canopy cover measurements were made to the nearest 5cm. Trees in woodland types were sampled using a point -centered quarter method (Cottam and Curtis 1956). A total of 40 or more measurements were made using this technique. Basal area and point -to -plant distance to the nearest tree in each quarter of each point were recorded by species. Restrictions on sampling included measurements of live trees having a diameter -at -breast height of >llcm. Yi • • @.K. • a Us It E361*3 t Primary productivity of herbaceous plants and selected half -shrubs was is measured using a harvest method. Rectangular quadrats (0.25m2) were randomly located within the sampling area (Figure 1). Harvesting was done by fractions including annual forbs, annual grasses, perennial forbs, perennial grasses and half -shrubs. Specific fractions were clipped for important species of forbs, grasses and half -shrubs. Specific fractions were altered somewhat between sampling areas depending on the species present. Current year's growth was sampled for all fractions. All samples were placed in kraft bags and air dried. Field data have been transcribed onto magnetic tape using a Wang 2200 MVP Minicomputer. Raw data barks put into the computer have been mathematically reduced to summarize cover, density and frequency by species for herbs, half -shrubs, shrubs and trees. Computations performed in reducing data were those derived from literature containing details of methodologies used, as follows: Herbs (Dix 1961), Shrubs (Lindsey 1955) . and Trees (Cottam and Curtis 1956).
