High-tech maps of tropical forest diversity identify new conservation targets.

New remote sensing maps of the forest canopy in Peru test the strength of current forest protections and identify new regions for conservation effort, according to a report led by Carnegie's Greg Asner published in Science.

Asner and his Carnegie Airborne Observatory (CAO) team used their signature technique, called airborne laser-guided imaging spectroscopy, to identify preservation targets by undertaking a new approach to study global ecology -- one that links a forest's variety of species to the strategies for survival and growth employed by canopy trees and other plants. Or, to put it in scientist-speak, their approach connects biodiversity and functional diversity.

Asner and his laboratory team were able to bridge this gap between field biodiversity studies and satellite-based mapping by revealing the distribution and concentrations of the key plant chemicals that indicate a forest canopy's function as well as its identity.

Major risks to tropical forests in Peru include gold mining, oil palm plantations, and cattle ranching, which have spurred the majority of a 500 percent increase in deforestation since 2010, in addition logging and oil exploration, according to Carnegie's project partner, the Peruvian Ministry of Environment (MINAM). Despite ongoing forest losses, the Carnegie and MINAM team was able to find about 30 million acres of biologically unique lowland Amazonian forest and 7 million acres of peatland forest in northern Peru that could be conserved, as well as 1.5 million acres of distinct submontane and high Andean forests that are highly threatened.

If and when the CAO spectrometer is launched into space, conservationists will be able to see biodiversity from space!
