When measuring the diameter or circumference is not infrequent errors.<\/span> A frequent mistake is in the location of the measurement, among others:<\/span> The use of tools in the right way with adequate skills automatically constitute a correction.<\/span> Similarly, when the scale reading should be done carefully.<\/span> When an error occurs laying tools, may be repaired, but a mistake while reading scale can not be repaired (corrected).<\/span> Therefore, the precision when measuring the diameter or circumference is preferred.<\/span><\/p>\n Accuracy measure the diameter or circumference (tree stand or fall) depends on several factors, among others:<\/span> However, problems that often occur when the dimensional measurements of trees (diameter or circumference, height or length) is at kekurangcermatan when taking measurements.<\/span> The inaccuracy affects the basal area (LBDs) and also the volume of the tree.<\/span> Therefore, to improve the level of precision diameter measurement, then:<\/span> Tree wetland (swamp \/ brackish)<\/strong><\/span>

\n (A) The measurements were performed at least twice (except the measuring tape) remember circle trunk not a full circle.<\/span>
\n (B) The reading of the current scale of measurement must carefully.<\/span> Measurement trees (stand or fall) small diameter requires a precision that is higher than a larger diameter.<\/span><\/p>\n
\n Location of measuring the diameter or circumference (LPD) on a tree trunk that grows in wetlands (swamp \/ brackish) is based on the type of tree.<\/span> Some examples can be seen below.<\/span><\/p>\n\n
\n Location of measuring the diameter or circumference (LPD) on a tree trunk types Bruguiera spp.<\/span> is as high as 1.30 m above the root.<\/span> Measuring the diameter or circumference of the tree trunk as shown in Figure 21.<\/span><\/li>\n<\/ul>\n

\n Location of measuring the diameter or circumference (LPD) on a tree trunk types Ceriops spp.<\/span> is as high as 1.30 m above the roots that borders the water.<\/span> However, things that must be considered is the type of Ceriops spp.<\/span> have buttressed roots that need to be reviewed in advance how much altitude the buttresses.<\/span> If the height of the buttresses of less than 1.30 m, 1.30 m tall LPD do limit the roots that hit the water.<\/span> Measuring the diameter or circumference of the tree trunk as shown in Figure 22.<\/span><\/li>\n<\/ul>\n
