New laser scanning technologies developed at the University of Salford are being used to map forests in more detail than ever before.

The technology could help give earlier and better data on the impacts of climate change on nature.

Papers - Week - Royal - Society - Researchers

In two new papers published this week by the Royal Society, researchers at Salford, UK Forest Research and the Universities of York St John, University College London, Newcastle and Tampere, Finland, described the impacts of terrestrial laser scanners on mapping plant life.

Mark Danson, professor of geography at the University of Salford said: "Climate change has led to earlier spring growth in forests in many part of the world but measuring the amount of leaves present in a forest canopy through time is currently almost impossible.

Research - Methods - Leaf - Growth - Forests

"Our research is testing new methods to map three-dimensional leaf growth in forests, so that rather than rely on an 'observer' spotting growth in a forest on a given day, we can map the spatial and temporal changes in leaf development remotely."

Prof Danson has developed the Salford Advanced Laser Canopy Analyser (SALCA), the first operational scanner capable of distinguishing between leaf and wood and also capable of creating three-dimensional maps of leaf distribution for both single trees and complete forest stands.

Approach - Measurement - Leaf - Dynamics - Forests

The approach promises to revolutionise the measurement of leaf dynamics in forests providing key information that can be related to climate change.

To check the accuracy of leaf maps, the team counted the leaves on three large oak...
