. A primer on stand and forest inventory designs. Forests and forestry Mensuration; Forest surveys. The total estimates of area and volume by vegetation type are similarly computed. Combined estimates are 6,240 acres for the conifer type, 7,965 acres for the hardwood, and 1,095 acres for the brush/open type. Volume esti- mates are 103,757 ccf for the conifer type, 131,500 ccf for the hardwood, and 1,890 ccf for the brush/open type.

Stand Estimates—Previously measured and newly mea- sured stands are assigned their actual values. Unmeasured stands are assigned the stratum averages from the new inventory. The average volume per acre for unmeasured conifer stands is ccf, ccf for hardwoods and ccf for brush vegetation types. See figure 37. Discussion—This application makes use of all available information and permits the calculation of sampling errors in which a good deal of credibility can be placed. It is the method that would be preferred if there were no additional information on portions of the forest. Complete Enumeration Complete enumeration of stands requires visiting and mea- suring every stand in the compartment. Sample plots are virtually always established within the stands rather than measuring every tree. The Southern (Belcher 1984) and Eastern Regions (Johnson 1984) have used this technique.
