Abstract:
This study details the development of a U. S. Commonwealth of Puerto Rico above-ground forest biomass ( 〈 small 〉 AGB 〈 /small 〉 ) product (baseline 2000) developed by the United States Environmental Protection Agency ( 〈 small 〉 EPA 〈 /small 〉 ) that was compared to another 〈 small 〉 AGB 〈 /small 〉 product developed by the U. S. Forest Service ( 〈 small 〉 USFS 〈 /small 〉 ) for the same area. The 〈 small 〉 USEPA 〈 /small 〉 product tended to over-predict in areas of low biomass and under-predict in high biomass areas when compared to observed plot
data, but compared favorably to a Forest Inventory Analysis ( 〈 small 〉 FIA 〈 /small 〉 ) assessment of structure and condition of Puerto Rico forests (72.6 Mg/ha versus 80.0 Mg/ ha, respectively). 〈 small 〉 AGB 〈 /small 〉 estimates were highly correlated with reference 〈 small 〉 FIA 〈 /small 〉 biomass for both maps at their native spatial resolutions ( 〈 small 〉 USEPA 〈 /small 〉 : r =0.93, 〈 small 〉 USFS 〈 /small 〉 : r = 0.92). 〈 small 〉 AGB 〈 /small 〉 mean difference between both products was 33.5 Mg/ha ( 〈 small 〉 USFS 〈 /small 〉 mean = 106.1 Mg/ha; 〈 small 〉 USEPA 〈 /small 〉 mean = 72.6 Mg/ha), a difference not out-of-scope when compared to other biomass comparative studies.
