diameter at breast height (DBH)
The answer depends on the individual measurement in question as well as the mean and standard deviation of the data set.
Yes.
The 7 in this case would be a modifier in this case this would mean .0000001
A meter is a measurement. 1m = 100cm 1m = 1000mm
Ha is the abbreviation for hectare. hectare is a unit of measurement.

To calculate biomass volume using a power function, you typically apply an allometric equation that relates the biomass of a plant to its measurable characteristics, such as diameter at breast height (DBH) or height. The general form of the equation is ( B = a \cdot (DBH^b) ), where ( B ) is the biomass, ( a ) and ( b ) are constants derived from empirical data specific to the species or ecosystem. By measuring the DBH or height of the trees, you can substitute these values into the equation to estimate biomass volume. This method assumes a specific relationship between the measured parameters and the biomass, which can vary by species and environmental conditions.

A maple tree should typically be at least 10 to 12 inches in diameter at breast height (DBH) to be tapped for sap. Trees of this size can usually yield enough sap for a productive tapping. It's also important to consider the tree's overall health; healthy trees can better withstand the tapping process. Generally, one tap is sufficient for trees up to 18 inches in diameter, while larger trees may accommodate two taps.
