abstract = "We tested if structural changes in the canopy of terra firme
forests in the Central Amazon caused by edge effects and
fragmentation can be identified using rangefinder LiDAR. We
compared forest fragment edge, fragment interior, and continuous
forest in areas of the Biological Dynamics of Forest Fragments
Project (BDFFP). We obtained the following canopy structural
attributes: leaf area index, leaf area density in vertical
profiles, canopy cover, height and rugosity of the upper canopy
surface. These were derived from 100m long 2D profiles obtained
with an upward-looking rangefinder LiDAR (Riegl LD90 - VHS3100 -
FLP). The system (LiDAR, gimbal, computer and batteries) was
carried by a field operator walking at a constant speed, using a
metronome. The sensor was maintained 1m above the ground.
Vegetation at the fragment edge had significantly lower canopy
height and density understory compared to continuous forest.
However, canopy cover and rugosity showed no significant
difference. We concluded that LiDAR is a valuable tool, capable of
identifying structural changes in the canopy caused by edge
effects and fragmentation.",
