Pics, shoots and leaves: Ecologists turn digital cameras into climate change tools
Date:12/19/2012

As digital cameras become better and cheaper, ecologists are turning these ubiquitous consumer devices into scientific tools to study how forests are responding to climate change. And, they say, digital cameras could be a cost-effective way of visually monitoring the spread of tree diseases. The results which come from 38,000 photographs are presented at this week's British Ecological Society's Annual Meeting at the University of Birmingham.

Because trees fix carbon dioxide (CO2) from the atmosphere and store carbon as biomass and soil organic matter, forests play a vital role in helping regulate climate change. Forests are also affected by climate change, with buds bursting sooner as spring arrives earlier, and ecologists need to understand how this process affects the amount of carbon trees can lock away from the atmosphere.

Studying how forests take up CO2 during photosynthesis is a complex and costly business involving a world-wide network called FLUXNET, which monitors the exchange of CO2 between the atmosphere and forests from more than 500 instrument towers worldwide using a technique known as eddy covariance. Now, Toshie Mizunuma of the University of Edinburgh has developed a way of using the seasonal changes in forest colour captured in digital photographs to calculate how much CO2 deciduous trees soak up.

"Reliably predicting CO2 flux isn't easy because it varies a lot due to changes in weather and alterations in forest metabolism caused by pests and diseases. We also still do not understand what controls the timing of leaves coming out in spring and falling in autumn. So we need a cheaper, simpler way of gathering this long-term data," Mizunuma explains.

To work out how to use digital cameras to capture this data, in 2009 the team working with Mizunuma set up two different camera systems in Alice Holt Forest, Hampshire. A commercial oak forest planted in the 1930s, Alice Holt contains a 90 ha research plot whi
