Automated remote photography is a convenient, labor-saving research tool for tracking leaf function and doing forest research. But does photography mirror what’s actually happening on the ground? A new study finds photography accurately tracks the timing of red pigments in the fall, but the timing of green in the spring and summer — not so much.

PROVIDENCE, R.I. [Brown University] — Every picture tells a story, but the story digital photos tell about how forests respond to climate change could be incomplete, according to new research. (more…)

Some 55% of tropical forests are negatively affected by land use practices and deforestation worldwide. But the ability to penetrate the canopy to see what’s going on has been lacking until now.

Global Ecology’s Greg Asner’s group has developed new airborne methods to peer through the canopy to measure and map, in beautiful 3-D, the underlying vegetation, degradation and deforestation, and the amount of carbon stored and emitted in these forests. (more…)

WASHINGTON — Using satellite data, scientists have produced a first-of-its kind map that details the height of the world’s forests. Although there are other local- and regional-scale forest canopy maps, the new map is the first that spans the entire globe based on one uniform method.
