CTFS-SIGEO Database Workshop in Peoria, Illinois

Members of the North America and Africa Programs of the Center for Tropical Forest Science (CTFS) - Smithsonian Institution Global Earth Observatory (SIGEO) met at Bradley University in Peoria, Illinois, this past week, 15-18 February, 2010, for a workshop on database management.

The workshop was hosted by Dr. Steven Dolins, Professor of Computer Science at Bradley. In partnership with Rick and Suzanne, Steven and his students have taken a lead role in developing the CTFS-SIGEO database system. Rick Condit and Suzanne Lao (STRI) designed and led the training activities. They were ably assisted by Mark Overholt, a computer science graduate from Bradley who has recently joined CTFS-SIGEO to help develop the database programs for the network.

This workshop was the 5th in a series of CTFS-SIGEO database workshops designed to train network members in the use of a global standardized database for all 3.5 million trees, 11 million records, and 8,000 species in the 34 plots of the network. By the end of the week, all participants were feeling very "normalized."

Coordinator of Africa Program Appointed: Dr. David Kenfack

We are pleased to announce that Dr. David Kenfack has recently joined the Center for Tropical Forest Science-Smithsonian Institution Global Earth Observatory (CTFS-SIGEO) to coordinate research and training activities for the Africa program.

David is no stranger to CTFS. In 1996, he led the establishment of the Korup 50-hectare plot in Cameroon. He then went on to PhD studies at the University of Missouri, St. Louis, where he worked on the systematics and ecology of Carapa (Meliaceae), describing a series of species new to science. Following the completion of his PhD in 2008, he spent a year as a postdoctoral fellow at the University of Michigan, Ann Arbor.

In addition to taxonomic expertise on the flora of Central and West Africa, David has extensive experience in tropical forest ecology and data management. During his career, he has assembled botanical collections and carried out forest inventories in more than 10 tropical countries.

David will be based at the CTFS office at the Arnold Arboretum of Harvard University.

Arnold Arboretum’s Robert Cook retires after 21 years

Last month, Robert E. Cook retired as director of the Arnold Arboretum of Harvard University after having led the institution for over two decades. The Arnold Arboretum’s involvement with CTFS goes back to the early 1980s when Steve Hubbell and Peter Ashton (then director of the Arboretum) agreed to replicate the BCI plot in Malaysia. Today the CTFS network comprises 34 plots around the world and represents a rich, exemplary tradition of collaborative science.

Bob Cook has played a significant role in sustaining and advancing CTFS research and training, particularly in tropical Asia. Under his directorship in 2003, the Arboretum joined the Smithsonian Tropical Research Institute in supporting CTFS’s core Asian research. That agreement was renewed in 2007 with the Arboretum furthering its commitment to CTFS research in Asia.

Bob has also been instrumental in involving CTFS in undergraduate and graduate education at Harvard and abroad. Through its annual Biodiversity of Borneo summer course and International Field Biology Course, CTFS exposes students to the remarkable biodiversity of the Asian tropics and introduces them to the complexities of conservation and forest management.

Plant science has benefited greatly from Bob’s long career in research and academic administration. In 1989, he came to the Arnold Arboretum from Cornell University, where he had been the director of Cornell Plantations and an associate professor of ecology and systematics. Prior to that he was an associate professor at Harvard. We appreciate his support and leadership over many years and wish him the very best in retirement.

Third Bornean forest dynamics plot launched

A new 50 ha forest dynamics plot will be established in lowland dipterocarp forest at Danum Valley in Sabah, Malaysia. The plot, which will follow CTFS protocols, adds a third site to the existing Bornean forest dynamics plots at Lambir (Sarawak) and Belalong (Brunei). It is designed to sample the rich flora of central Borneo on relatively nutrient-rich soils. The project represents a collaboration between David Burslem (Aberdeen University, UK), Glen Reynolds (Royal Society SEARRP), Andy Hector (University of Zurich, Switzerland), Waidi Sinun (Sabah Foundation), and CTFS and is funded by HSBC Malaysia for a period of five years.

The plot is part of the Royal Society's South East Asia Rain Forest Research Programme, which has operated the Danum Valley Field Centre with local partners since 1985 (see www.searrp.org). The plot will be located in undulating landscape of the Danum Valley Conservation Area and will provide a baseline for on-going studies of forest regeneration, carbon dynamics and biodiversity in adjacent logged forest and forest fragmented by oil palm plantations. Plot establishment will start at the end of this year. For further details contact David Burslem (d.burslem@abdn.ac.uk) or Glen Reynolds (glen.searrp@me.com).

Data-analysis workshop in Beijing

Text contributed by Dr. Mi Xiangcheng

To better understand the mechanisms of biodiversity maintenance in forests of the Chinese Forest Biodiversity Monitoring Network (CForBio), the Biodiversity Committee of the Chinese Academy of Sciences and CTFS hosted a workshop on data analysis and management in Beijing on 14-24 October 2009. The workshop was led by Drs. Richard Condit, Shameema Esufali, and Yu-Yun Chen. Twenty-eight people from seven CForBio plots participated in the workshop.

Condit and Esufali used BCI plot data to demonstrate a variety of data-analysis methods, including maximum likelihood and MCMC. These demonstrations illustrated in detail the advantages and disadvantages of each method. Participants also received instruction in R and completed a series of computations.

The course on data management used the Gutianshan plot’s database for instruction in the establishment, management, and maintenance of plot data, all of which are essential to CTFS research. The intensive two-week workshop greatly enhanced participants’ ability to analyze and manage data, further strengthening by extension the entire network’s ability to investigate forest dynamics.
