biomass_basis.as_biopak(woodden, x, b1, b2, b3, j1, j2, *args)¶ shapes a biomass equation based on inputs of b1, b2 and wood density onto the variable x which is for the dbh. does not use height or wood density directly
-
biomass_basis.as_chinq_biopak(woodden, x, b1, b2, b3, j1, j2, h1, h2, h3)¶ shapes a biomass equation based on inputs of h1, h2, h3, b1, b2, and b3, plus wood density onto the variable x which is for the dbh. uses pretty much all the inputs directly and calculates volume. chinquapin.
-
biomass_basis.as_compbio(x, parameter_rows)¶ shapes a biomass equation based on the inputs of b1, b2, and wood density onto the variable x which is the dbh. adds the components from each row in the table it needs. only works with a few trees.
-
biomass_basis.as_d2ht(woodden, x, b1, b2, b3, j1, j2, h1, h2, h3)¶ shapes a biomass equation based on inputs of h1, h2, h3, and b1 and wood density onto the variable x which is for the dbh
-
biomass_basis.as_d2htcasc(woodden, x, b1, b2, b3, j1, j2, *args)¶ shapes a biomass equation based on inputs of b1, b2, b3, and wood density onto the variable x which is for the dbh. cascades variety does not need height or the adjustment by m2
-
biomass_basis.as_lnln(woodden, x, b1, b2, b3, j1, j2, *args)¶ shapes a biomass equation based on inputs of b1, b2, b3, and wood density onto variable x which is for the dbh
-
biomass_basis.as_oak_biopak(woodden, x, b1, b2, b3, j1, j2, h1, h2, h3)¶ shapes a biomass equation based on inputs of h1, h2, h3, b1, b2, and b3, plus wood density onto the variable x which is for the dbh. uses pretty much all the inputs directly and calculates volume. things in quercus family.
-
biomass_basis.maxref(dbh, species)¶ check if an instance of dbh and species is bigger than the max. the max was found from the upper 1 percent ( I think!) per tree
-
biomass_basis.which_fx(function_string)¶ find the correct function for doing the biomass in the lookup table
