Rainforest rehab in every sense
June 12, 2009Sophisticated sensors that measure leaf wetness, soil moisture and temperature are helping rehabilitate rainforest in the Springbrook World Heritage precinct in south-east Queensland.
The CSIRO sensors are being used to uncover the microclimatic conditions favourable for rapid natural regeneration of degraded rainforest environments.
A network of ten sensor nodes, connected wirelessly, has been sampling parameters such as rainfall, humidity, temperature, soil moisture and the amount of available light inside the forest every five minutes since May 2008.
Over the next two years, another 200 nodes will be installed, some of which will measure biodiversity indicators, such as bird and frog calls.
CSIRO ICT Centre Research Scientist, Darren Moore, said the sensors are solar-powered and have been developed specifically for monitoring the complex, interlinked variables found in natural environments.
"In the rainforest, there is limited sunlight under the canopy which means we've had to develop sophisticated techniques to manage power," Mr Moore said.
"Our nodes are able to stay on-line, adaptively reducing their workload, to minimise the amount of power used."
Queensland Department of Environment and Resource Management spokesman, Jonathan Hodge, said the technology is helping to "push the boundaries of environmental science."
CSIRO's Sensor Network Technologies Research Director, Dr Michael Bruenig said the Springbrook project demonstrates that real-time data can be streamed back from open and covered rainforest using a low bandwidth wireless sensor network.
"CSIRO's FLECK™ devices are capable of low-powered wireless mesh networking, intelligent energy management and interfacing to a broad range of sensors," Dr Bruenig said.
"They are providing the capability to provide reliable, long-term monitoring of the natural environment which - in the case of Springbrook - can be applied to rainforest ecosystems."

Rainforest Current Events and Rainforest News RSSResearchers Hail Innovative Plan to Save Rainforest, Reduce Greenhouse Gas Emissions
An innovative proposal by the Ecuadorian government to protect an untouched, oil rich region of Amazon rainforest is a precedent-setting and potentially economically viable approach, says a team of environmental researchers from the University of Maryland, the World Resources Institute and Save America's Forests.
Plant fossils give first real picture of earliest Neotropical rainforests
A team of researchers including a University of Florida paleontologist has used a rich cache of plant fossils discovered in Colombia to provide the first reliable evidence of how Neotropical rainforests looked 58 million years ago.
The first neotropical rainforest was home of the Titanoboa
Smithsonian researchers working in Colombia's Cerrejón coal mine have unearthed the first megafossil evidence of a neotropical rainforest.
World will miss 2010 target to stem biodiversity loss, experts say
The world will miss its agreed target to stem biodiversity loss by next year, according to experts convening in Cape Town for a landmark conference devoted to biodiversity science.
Killer bees may increase food supplies for native bees
Aggressive African bees were accidentally released in Brazil in 1957. As "killer bees" spread northward, David Roubik, staff scientist at the Smithsonian Tropical Research Institute, began a 17-year study that revealed that Africanized bees caused less damage to native bees than changes in the weather and may have increased the availability of their food plants.
Climate caused biodiversity booms and busts in ancient plants and mammals
A period of global warming from 53 million to 47 million years ago strongly influenced plants and animals, spurring a biodiversity boom in western North America, researchers from three research museums report in a paper published online this week in the Proceedings of the National Academy of Sciences.
Bizarre walking bat has ancient heritage
A bizarre New Zealand bat that is as much at home walking four-legged on the ground as winging through the air had an Australian ancestor 20 million years ago with the same rare ability, a new study has found.
New isotope cluster could lead to better understanding of atmospheric carbon dioxide
A team of researchers has discovered an unexpected concentration of a certain isotopic molecule in parts of the stratosphere that could have implications for understanding the carbon cycle and its response to climate change.
World's largest aerosol sensing network has leafy origins
Twenty years ago, Brent Holben was part of a NASA team studying vegetation from space. In an unlikely career twist, his research morphed into the study of a critical, if overlooked, subplot in the story of climate change.
Amazon conservation policy working in Brazil, MSU-led study finds
Contrary to common belief, Brazil's policy of protecting portions of the Amazonian forest from development is capable of buffering the Amazon from climate change, according to a new study led by Michigan State University researchers.
