Drones could monitor the success of forest regeneration in the tropics,
suggests a new study published in Biological Conservation. The researchers say
automating the monitoring process leads to equally accurate results and could
save a significant amount of time and money.

The new research has been selected by an international scientific committee
to be given the Atlas award.

Between 1990 and 2005, the world's rainforests were depleted by more than
8% through deforestation, in part to make way for agriculture. Today, large
areas of agricultural land are being restored to rainforest to meet
conservation goals in the tropics. It is important to monitor the success of
these efforts to ensure that these areas are replenished with the right
vegetation.

There are many drivers for conservation efforts, including governmental
subsidies, and many of the people implementing the projects are individual land
owners. Monitoring regeneration can be labor intensive and expensive, making it
difficult to know whether conservation efforts have been successful.

However, using unmanned aerial vehicles -- or drones -- to replace manual
monitoring under certain conditions could save considerable costs, making the
monitoring process more feasible for scientists.

"It's early days but drones have great potential for monitoring
restoration efforts in tropical forests," said lead author of the study
Dr. Rakan Zahawi, from the Organization for Tropical Studies. "We've shown
that using drones to replace manual labor can reduce the costs associated with
monitoring conservation projects. This could result in more people monitoring
their land in the tropics, giving us better information about what works and
what doesn't."

Traditionally, rainforest regeneration has been monitored manually. This
requires skilled, knowledgeable people and specialist equipment, and can be
especially challenging if the land is difficult to access. An alternative to
manual monitoring is LiDAR -- remote sensing technology that analyzes reflected
light. However, a single LiDAR flight to monitor forest recovery remotely can
cost upwards of $20,000.

In the new study, Dr. Zahawi and the team, including researchers from the
University of Maryland and the University of California-Santa Cruz, USA, tested
a new automated approach to monitoring that doesn't involve manual
intervention. Using inexpensive drone-based remote sensing technology, the
researchers measured the structure of the forest canopy across a series of
1-hectare regenerating fields that were previously agricultural land in
southern Costa Rica. The land is part of a long-term tropical forest
restoration study.

The drones were fitted with a simple 10 megapixel point-and-shoot digital
camera and use open-source software to process these overlapping images. The
camera takes thousands of photos and the "Ecosynth" methodology then
creates 3D images called point clouds that represent the vegetation. In total,
the drone and camera cost US$1500 -- less than a tenth the cost of some
equivalent flights.

The researchers compared the results produced by Ecosynth for canopy
height, above ground biomass and canopy structure -- whether the canopy was
rough or open -- to field based measures. They also evaluated whether
Ecosynth-measured canopy height could predict the abundance of fruit-eating
(frugivore) birds as accurately as field based height measures; many
fruit-eating birds, such as the mountain thrush, black guan and sooty-capped
bush tanager, are important for forest regeneration. The results showed that
Ecosynth was as accurate as human monitoring, although there were some errors
when the canopy was low.

"There is still some work to do to optimize Ecosynth and make sure
measurements are accurate in all situations. However, the approach has real
promise in monitoring regeneration," said Dr. Zahawi. "The reduced
cost and labor intensity means that many more farmers will be able to monitor
their land, giving us far more data about how best to conserve tropical
forests."
