fuel_cons_harvester_1 {care4cmodel}

Fuel Consumption of a Harvester per Cubic Meter Harvested Wood (Version #1)

Description

Fuel consumption depends on the average tree volume. For tree diameters at breast height < 15 cm the function gives back NA, because the assumed machine does not work with such small trees. Estimated after Bacescu et al. (2022).

Usage

fuel_cons_harvester_1(tree_vol, tree_dbh)

Arguments

tree_vol

Average standing merchandable wood volume over bark (m³) per harvested tree

tree_dbh

Average diameter at breast height (cm) per harvested tree

Value

Fuel consumption of a harvester in liters diesel fuel per m³ harvested wood
