Bog birch, paper birch, and various willow species were often present.","ecosystem_type":"Boreal forest","koppen":"Dfc","dbh_min_cm":"0.3","dbh_max_cm":"1","sample_size":"10","collection_year":"1994, 1999, 2000","dbh_units_original":"cm","dbh_unit_CF":"1","output_units_original":"g","output_units_CF":"0.001","allometry_development_method":"harvest","regression_model":"log-log transformed (base10)","r_squared":"0.54","other_equations_tested":"NI","log_biomass":"1","bias_corrected":"1","bias_correction_factor":"1.121","notes_fitting_model":"A logarithmic transformation was used to correct for heterogeneous variation of the independent diameter variable, and a correction factor was computed for all equations to correct for the systematic bias","original_data_availability":"NRA"} {"ref_id":"bridge_1979_fpom","equation_id":"23ec05","equation_allometry":"exp(-0.34052+2.65803*log(dbh))","equation_form":"exp(a+b*log(dbh))","dependent_variable":"Whole tree (above stump)","independent_variable":"DBH","equation_taxa":"Quercus velutina","allometry_specificity":"Species","equation_categ":"sp_spec","geographic_area":"Rhode Island, USA","original_coord":"41°27'51\" N, 71°35'11\" W","lat":"41.5","long":"-71.6","elev_m":"36","mat_C":"9.4","min.temp_C":"NI","max.temp_C":"NI","map_mm":"1124","frost_free_period_days":"NI","stand_age_range_yr":"50 yrs","stand_age_history":"Stands affected by widespread occurrence of wild fires and repeated clear-cuttings","stand_basal_area_m2_ha":"NI","stand_trees_ha":"NI","forest_description":"Mixed hardwoods (Acer rubrum, mixed oaks)","ecosystem_type":"Temperate forest","koppen":"Cfb","dbh_min_cm":"7.62","dbh_max_cm":"30.48","sample_size":"26","collection_year":"1978","dbh_units_original":"inch","dbh_unit_CF":"0.393701","output_units_original":"kg","output_units_CF":"1","allometry_development_method":"harvest","regression_model":"log-log transformed","r_squared":"0.88","other_equations_tested":"NI","log_biomass":"1","bias_corrected":"0","notes_fitting_model":"Linear regressions for species were tested for differences in slope and level according to Freese (1967).
