abstract = "Fire is one of the main factors directly impacting Amazonian
forest biomass and dynamics. Because of Amazonias large
geographical extent, remote sensing techniques are required for
comprehensively assessing forest fire impacts at the landscape
level. In this context, Light Detection and Ranging (LiDAR) stands
out as a technology capable of retrieving direct measurements of
vegetation vertical arrangement, which can be directly associated
with aboveground biomass. This work aims, for the first time, to
quantify post-fire changes in forest canopy height and biomass
using airborne LiDAR in western Amazonia. For this, the present
study evaluated four areas located in the state of Acre, called
Rio Branco, Humait{\'a}, Bonal and Talism{\~a}. Rio Branco and
Humait{\'a} burned in 2005 and Bonal and Talism{\~a} burned in
2010. In these areas, we inventoried a total of 25 plots (0.25 ha
each) in 2014. Humait{\'a} and Talism{\~a} are located in an
open forest with bamboo and Bonal and Rio Branco are located in a
dense forest. Our results showed that even ten years after the
fire event, there was no complete recovery of the height and
biomass of the burned areas (p < 0.05). The percentage difference
in height between control and burned sites was 2.23% for Rio
Branco, 9.26% for Humait{\'a}, 10.03% for Talism{\~a} and 20.25%
for Bonal. All burned sites had significantly lower biomass values
than control sites. In Rio Branco (ten years after fire),
Humait{\'a} (nine years after fire), Bonal (four years after
fire) and Talism{\~a} (five years after fire) biomass was 6.71%,
13.66%, 17.89% and 22.69% lower than control sites, respectively.
The total amount of biomass lost for the studied sites was
16,706.3 Mg, with an average loss of 4176.6 Mg for sites burned in
2005 and 2890 Mg for sites burned in 2010, with an average loss of
3615 Mg. Fire impact associated with tree mortality was clearly
detected using LiDAR data up to ten years after the fire event.
This study indicates that fire disturbance in the Amazon region
can cause persistent above-ground biomass loss and subsequent
reduction of forest carbon stocks. Continuous monitoring of burned
forests is required for depicting the long-term recovery
trajectory of fire-affected Amazonian forests.",
