Coordinator of CTFS/SIGEO-TEAM Initiative Appointed: Dr. Patrick Jansen

We are very pleased to announce that Dr. Patrick Jansen has recently joined the Center for Tropical Forest Science-Smithsonian Institution Global Earth Observatory (CTFS-SIGEO) to coordinate research activities for the CTFS-SIGEO collaboration with Conservation International’s Tropical Ecology Assessment and Monitoring Network (TEAM). The partnership between CTFS-SIGEO and TEAM will expand the long-term monitoring of biodiverse tropical forests by implementing a program of vertebrate and climate monitoring.

Patrick comes to CTFS-SIGEO from a postdoctoral fellowship at the University of Groningen in the Netherlands. He received his BSc and MSc from Wageningen Agricultural University and his PhD from Wageningen University. His expertise in the study of plant-animal interactions, particularly seed dispersal and seed predation, and his experience with camera trapping of terrestrial vertebrates will complement and enhance the growing CTFS-SIGEO research program.

HSBC Climate Partnership yields initial research findings

Researchers from around the world met last week at the Smithsonian Tropical Research Institute (STRI) in Panama to present mid-term research results from the HSBC Climate Partnership, a five-year initiative to identify and respond to the impacts of climate change. The program is supported financially by HSBC and involves a global team of bank employees—“climate champions”—in vital forest research.

The first-ever research program of its kind has so far:
• Found rapid increases in tree growth in the forest around the Smithsonian Environmental Research Center (SERC) in Maryland, USA, a finding that corresponds to increased atmospheric carbon dioxide and longer growing seasons, published in PNAS.
• Proposed a novel biodiversity theory relating stress and seed-size published in PNAS.
• Examined the effects a changing climate in forests is having on white-tailed deer, mice and even mosquitoes.
• Addressed the lack of a reliable method for estimating the carbon storage capability of secondary forests on a landscape scale by assessing how measurements from airborne LiDAR and other remote sensing technologies relate to ground-based measurements.
• Reviewed how human disturbance changes the way forests take up carbon in diverse environments.

Researchers working in broadleaf-forest plots near Oxford, UK, Atlantic rainforests in southern Brazil, and warm-temperate forests near Gutianshan Nature Reserve in China, as well as the SERC site in Maryland, have been putting HSBC employees to work. At Oxford, for example, data collected indicates that changes in forest structure have impacted moth populations.

Stuart Davies, director of the Smithsonian and Harvard’s Center for Tropical Forest Science, says, “We know that carbon dioxide in the atmosphere has shot up from 280 to 385 parts per million since the 1850s as a result of human activities like the burning of fossil fuels and deforestation. The degree to which atmospheric carbon dioxide levels continue to increase depends, in part, on how trees respond to climate and atmospheric change—whether forests end up storing more or less carbon. This is what the HSBC Climate Partnership research is trying to establish.”

Dan Bebber, head of climate change research at Earthwatch Institute, says, “Human activities are undeniably changing the world’s climate, but the effects of that change on forest ecosystems and the role that forests play in providing ecosystem services such as carbon storage are poorly understood. The research being supported by funding and climate champions from HSBC will help to increase our knowledge of forests, and how they can be wisely managed for the future. This unique NGO-corporate partnership is an exemplary model of how individuals and businesses can make a difference.”

STRI staff scientist Helene Muller-Landau said: “The HSBC Climate Champions working with us to measure trees understand how to take stock of carbon balances. Trees take up carbon as they grow. As trees die and decompose, they release carbon. The balance of carbon flows in and out of the forest determines whether the total forest carbon stock increases or decreases over time.”

“Dangerous and irreversible changes that threaten life-support systems are likely when atmospheric carbon levels reach 550 ppm, if not sooner,” stressed Yavinder Malhi, research scientist from Oxford University. “It’s our job to engage people in science in a way that balances keeping things simple while showing that forests, as living systems, may be really complicated, taking up carbon under some conditions and giving off carbon under other conditions.”

Research in Peru reveals how forest carbon budgets change with temperature from cooler mountainous sites to warmer lowland sites. Muller-Landau and Malhi agree that because different tree species respond differently to changing temperatures and rainfall regimes, some species will thrive while others will decline, resulting in changes in forest tree-species composition and probably in carbon stocks.

Another important topic of discussion at the conference was the HSBC-sponsored Panama Canal Watershed Experiment, nicknamed the Agua Salud Project. This huge experiment aims to determine how different land uses—pasture, plantations of native trees and teak, and mature forest—affect carbon storage, water flow, and biodiversity on the narrow Isthmus of Panama, where two great biodiversity hotspots meet. STRI Director Eldredge Bermingham noted “that locating this experiment on the banks of the Panama Canal aims to focus global attention on the ecosystem services that forests provide this critical commercial waterway.”

Third African Forest Dynamics Plot Underway

A new 25-ha forest dynamics plot is being established in mature forest in the Rabi Protected Area in the Gamba Complex of protected areas in southwestern Gabon. The plot follows CTFS protocols and adds a third site to the existing African plots at Ituri (Congo) and Korup (Cameroon). Studies by the Smithsonian over the last decade have shown the Gamba Complex area, which encompasses the Rabi plot, to be extremely biodiverse. The plot is representative of the Guineo-Congolian rainforest that abounds in the Rabi landscape.

The project is part of the Gabon Biodiversity Program and represents a collaboration between the Smithsonian Institution Global Earth Observatory (SIGEO), Smithsonian National Zoological Park Conservation Biology Institute and Center for Conservation, Education and Sustainability, Shell Gabon, the Government of Gabon, CTFS and other stakeholders. The plot will provide baseline data for studies of forest regeneration, carbon dynamics, and biodiversity. In addition, the plot affords the opportunity to help build scientific and resource-management capacity in the region. Late in 2009, researchers completed surveying 25-ha of the plot. Tree tagging, mapping, and identification will begin this year. For more information, please contact Alfonso Alonso or Francisco Dallmeier.
