Journal ArticleDOI
Selective logging in the Brazilian Amazon.
Gregory P. Asner,David E. Knapp,Eben N. Broadbent,Paulo J. Oliveira,Michael Keller,José Natalino Macedo Silva +5 more
TL;DR: This work developed a large-scale, high-resolution, automated remote-sensing analysis of selective logging in the top five timber-producing states of the Brazilian Amazon, equivalent to 60 to 123% of previously reported deforestation area.
Journal ArticleDOI
High-resolution forest carbon stocks and emissions in the Amazon
Gregory P. Asner,George V. N. Powell,Joseph Mascaro,David E. Knapp,John K. Clark,James Jacobson,Ty Kennedy-Bowdoin,Aravindh Balaji,Guayana Paez-Acosta,Eloy Victoria,Laura Secada,Michael Valqui,R. Flint Hughes +12 more
TL;DR: Very high-resolution monitoring reduces uncertainty in carbon emissions for REDD programs while uncovering fundamental environmental controls on forest carbon storage and their interactions with land-use change.
Journal ArticleDOI
Forest fragmentation and edge effects from deforestation and selective logging in the Brazilian Amazon
Eben N. Broadbent,Eben N. Broadbent,Gregory P. Asner,Michael Keller,David E. Knapp,Paulo J. Oliveira,José Natalino Macedo Silva +6 more
TL;DR: In this article, the authors quantified the effects of both deforestation and selective logging, separately and combined, on forest fragmentation and edge effects over large regions, and contextualized the spatio-temporal dynamics of this forest fragmentation through a literature review of potential ecological repercussions of edge creation.
Journal ArticleDOI
Land-use allocation protects the Peruvian Amazon.
Paulo J. Oliveira,Gregory P. Asner,David E. Knapp,Angelica Almeyda,Ricardo Galván-Gildemeister,Sam Keene,Rebecca F. Raybin,Richard J.H. Smith +7 more
TL;DR: Although the region shows recent increases in disturbance and deforestation rates and leakage into forests surrounding concession areas, land-use policy and remoteness are serving to protect the Peruvian Amazon.
Journal ArticleDOI
Condition and fate of logged forests in the Brazilian Amazon.
Gregory P. Asner,Eben N. Broadbent,Paulo J. Oliveira,Michael Keller,Michael Keller,David E. Knapp,José Natalino Macedo Silva +6 more
TL;DR: The results show that logging in the Brazilian Amazon is dominated by highly damaging operations, often followed rapidly by deforestation decades before forests can recover sufficiently to produce timber for a second harvest.
