Dear Daniel Magnabosco Marra,

after considering your comments in the published author's response how you will address the reviewer’s suggestion in the revised version of bg-2015-329, I am pleased to accept your manuscript for publication in Biogeosciences after a minor revision.

The critics and suggestions of Dr. R. McRoberts regarding possible sources of uncertainty in biomass prediction should be considered in the revised version as indicated in your author’s response. The revised version of bg-2015-329 should also present the indicated point-by-point responses to technical corrections and minor comments suggested by the two reviewers. Please substitute fig. 6 of the former manuscript by the figure indicated in the author response.

Again I apologize for the delay of the review process. Thank you for choosing Biogeosciences to publish this interesting study.

Best regards
Jochen Schongart

Title: Predicting biomass of hyperdiverse and structurally complex Central Amazon forests – a virtual approach using extensive field data

Authors: D. Magnabosco Marra, N. Higuchi, S. E. Trumbore, G. H. P. M. Ribeiro, J. dos Santos, V. M.C. Carneiro, A. J. N. Lima, J. Q. Chambers, R. I. Negrón-Juárez, F. Holzwarth, B. Reu, C. Wirth

Dear Daniel M. Marra,

after reading the manuscript and the supplementary information I ask you to perform the following technical corrections of the last revised version of the manuscript:

Please note that the word "Table" is never abbreviated and should be capitalized when followed by a number. Please check the entire manuscript.

L. 110, 521, 601 and 906: Jr instead of Junior (see line 109).

L. 178: I suggest to add “mainly during the rainy season”.

L. 203: plateaus (plural form).

L. 205: 1-ha plateau area?

L. 529: I suggest to be more specific here referring to the study site, as there are trees in the Central Amazon regions with such dimensions (e.g., Bertholletia excelsa, Ceiba pentandra among other species).

Table S4: I suggest to reduce the number of digits to one for the indicated values of Bias (Mg)

Best regards,
Jochen Schongart
