Borneo of Kutai

As a general standard, tree girth is taken at 'breast height'. This is cited as dbh (diameter at breast height) in tree and forestry literature.[3][20] Breast height is defined differently in different situations, with most forestry measurements taking girth at 1.3 m above ground,[20] while those who measure ornamental trees usually measure at 1.5 m above ground;[3] in most cases this makes little difference to the measured girth. On sloping ground, the "above ground" reference point is usually taken as the highest point on the ground touching the trunk,[3][20] but some use the average between the highest and lowest points of ground[citation needed]. Some of the inflated old measurements may have been taken at ground level. Some past exaggerated measurements also result from measuring the complete next-to-bark measurement, pushing the tape in and out over every crevice and buttress.
