CTFS – ForestGEO welcomes the Utah Forest Dynamics Plot (UFDP) to the global network!


CTFS – ForestGEO in affiliation with Utah State University, the Utah Agricultural Experiment Station, and the University of Montana welcomes the Utah Forest Dynamics Plot (UFDP) to the network after its first census completion in September of 2015!

UFDP is a research and educational project located in the subalpine forest of the Colorado Plateau in Cedar Breaks National Monument, Utah. The plot was established in the summers of 2014 and 2015 with Jim Lutz of Utah State University as the Principal Investigator (PI). This is the third plot in the Western Forest Initiative, which includes two additional CTFS – ForestGEO plots, the Wind River Forest Dynamics Plot (WFDP) and the Yosemite Forest Dynamics Plot (YFDP)

The plot is 13.2 ha in extent, with elevations ranging from 3,039 m to 3,169 m, the elevational limit of closed canopy forest at this latitude. The forest is characterized by a mosaic of mixed conifer/aspen forest types with over 22,000 live stems and 4,000 dead stems. The most abundant species are Abies bifolia (subalpine fir), Populus tremuloides (aspen), Picea engelmannii (Engelmann spruce), Pinus flexilis (limber pine), and Pinus longaeva (bristlecone pine).

Jim Lutz and his team are conducting research on changes to climate and the causes of tree mortality at UFDP. The research projects serve as a platform for education and training for students, biologists, and citizen-scientists through hands-on fieldwork experiences.

New field guide describing the lianas of Barro Colorado Island (BCI), Panama


ForestGEO presents a new field guide, Lianas y Enredaderas de la Isla de Barro Colorado, Panamá (Lianas and Vines of Barro Colorado Island, Panama) published by the Smithsonian Tropical Research Institute (STRI). The Spanish-language field guide is written by STRI’s Rolando Pérez, Salomón Aguilar, Nefertaris Daguerre, and Andrés Hernández, and STRI Research Associate Stefan Schnitzer with Marquette University.

The field book is a guide to identifying 124 common species of lianas and vines with descriptions, uses, and mapped distributions in the tropical forest of Barro Colorado Island (BCI) Forest Dynamics PlotBCI is a major focus of intensive research on lowland tropical moist forest and its flora is better known than any comparably sized site in the world. BCI has almost 1,500 vascular plant species, including 276 species of lianas and vines

Lianas and vines are difficult to track and measure across ForestGEO plots, including BCI. Both individuals and species are difficult to identify as they spiral up into the tree canopy. Vine and woody climbing lianas can inhibit the growth of tropical trees due to competition for light and other resources. However, the biology and ecological roles of these climbing plants is scarcely known. Therefore, the field book serves as an invaluable resource for studying the ecological roles of lianas and vines in tropical forests, and includes vibrant, color photographs of leaves, flowers, fruits, and vines, as well as a pictorial glossary of botanical terms.

CTFS - ForestGEO Africa Database Workshop and Symposium in Washington, D.C.

CTFS – ForestGEO hosted its Africa database training workshop last week in Washington, D.C. at the Smithsonian National Museum of Natural History. The 10-day workshop was generously supported by Chris Davidson. David Kenfack, CTFS – ForestGEO Africa Program Coordinator, and Suzanne Lao, CTFS - ForestGEO Database Manager, ran the workshop for five of our African forest dynamics plots partners. For most participants, this was their first time traveling to the United States, which provided an opportunity for the research team to meet and work together in person.

At the workshop, participants dove into learning data entry techniques through the CTFS database system.  The goal of the training workshop was to form capacity within each of the respective forest dynamics plot for managing and utilizing forest plot data. The participants learned numerous concepts from utilizing Structured Query Language (SQL) commands with sample data to creating and digitizing maps in R. The participants represented the forest plots in Gabon, Kenya, Cameroon, the Democratic Republic of Congo, and Nigeria.

On October 21st, CTFS – ForestGEO held a symposium at the museum, “Plant Systematics and the ForestGEO Network in Africa,” geared towards highlighting the workshop participants and their research. David Kenfack introduced the African forest dynamics plots and some of the plant systematics challenges we face in central Africa. Research talks followed by Pulcherie Bissiengou, Rabi forest plot in Gabon and the National Herbarium of Gabon, and Paul Musili, Mpala forest plot in Kenya and the National Museums of Kenya. Pulcherie discussed her recent dissertation work on the systematics, evolution, and historical biogeography of Ochnaceae. Paul Musili discussed systematic studies in Schoenus L. (Schoeneae, Cyperaceae) sedges in Kenya. The symposium concluded with David discussing the importance of long-distance dispersal for the biogeography of the transatlantic tree genus (Meliaceae, Sapindales).

CTFS - ForestGEO session at 100th-annual ESA meeting in Baltimore, MD

CTFS – ForestGEO recently hosted a session on Dimensions of Forest Diversity at the 100th annual Ecological Society of America (ESA) meeting in Baltimore, MD. Scientists presented some of the latest research coming out of the annual Dimensions of Biodiversity workshop between CTFS – ForestGEO and the Chinese Forest Biodiversity Monitoring Network. Thank you to all of the speakers and guests that attended!

The session began with an introduction by Stuart Davies, the Director of CTFS-ForestGEO, followed by ten presentations by CTFS - ForestGEO researchers. The session focused on the functional, phylogenetic, and genetic dimensions of forest diversity and change. Specifically, the presenters discussed how forests face multiple pressures from shifts in temperature and precipitation to deforestation and degradation associated with global climate change. For example, Andy Jones, Assistant Professor at Oregon State University, discussed species’ genetic responses to seasonal droughts in tropical forests and how results can inform future changes we face with upcoming El Niño events.

New field book features CTFS - ForestGEO plot in Yasuni, Ecuador

CTFS – ForestGEO, Pontificia Universidad Catolica del Ecuador (PUCE), and Dinamica del bosque de Yasuni present a new book, Árboles emblemáticos de Yasuní: 337 especies (Yasuni emblematic trees: 337 species), written by Alvaro J. Perez, Consuelo Hernandez, Hugo Romero-Saltos, and Renato Valencia, published by Herbario QCA.

The book is a field guide that displays morphological descriptions, uses, distribution, phenology, demographics, and accumulated carbon for 337 of the species in Yasuni National Park (314 species of trees, 22 species of palms, and one tree fern). 

In 1995, CTFS – ForestGEO helped establish the Yasuni Forest Dynamics Plot in Yasuni National Park, Ecuador in association with PUCE and the University of Aarhus in Denmark. This region is one of the greatest biodiversity hotspots on the planet with nearly 300,000 individual trees and 1100 species tagged in the plot.

Annual workshop at the pioneer forest plot: CTFS - ForestGEO partners in Panama


CTFS - ForestGEO wrapped up its fifth, annual Dimensions of Biodiversity data-analysis workshop in Gamboa, Panama—home of the Smithsonian Tropical Research Institute. Thanks to all 57 participants from 20 countries around the network,  CTFS - ForestGEO had another productive year in forest research!

Workshop priorities followed suit from previous years: to bring a global network to a local place to foster research and scientific collaborations among the CTFS – ForestGEO members. Every workshop is an opportunity to explore the latest research ideas with colleagues and meet new network researchers in person.

The workshop is an ongoing collaboration between CTFS – ForestGEO and the Chinese Forest Biodiversity Monitoring Network with the Chinese Academy of Sciences. The National Science Foundation has provided financial support for the workshops since the summer of 2011.

At the workshop, participants hunkered down on forest plot analyses focused on biomass and carbon storage, gradients of diversity, time-series analyses of forest dynamics, and much more. Breaks from data analyses and computer screens ensued throughout the day as participants heard scientific presentations and provided feedback on forest research happening around the global network.  With 57 forest scientists in one room, there was no lack of expertise! Local Smithsonian Tropical Research Institute scientists also joined the discussions and presented talks on the history of Panama and the immense amount of research occurring in tropical, Panamanian ecosystems.

Early inspiration for questions about forest dynamics came from a field trip to the CTFS – ForestGEO pioneer plot, Barro Colorado Island (BCI). An 8 AM boat ride through the Panama Canal brought the participants to BCI, where they all climbed to the first of the now 63 forest dynamics plots in the CTFS – ForestGEO network.  Everyone had a chance to get a glimpse  of the 302 tree species in the plot. Back at the workshop hotel site,  the BCI plant taxonomy guru and leader of the eighth BCI forest census, Rolando Pérez, walked everyone through the history and species of the local area on a guided natural-history tour of Panama’s diverse plant and animal life. Gamboa, Panama certainly provided an appropriate backdrop for a forest-studies workshop.

Preparations for the TY Danjuma supported Nigerian plot are continuing as scheduled


Forest biodiversity and conservation research in Nigeria has received a major boost with the donation by T.Y. Danjuma to the Nigerian Montane Forest Project (NMFP) for the establishment of a long-term, large-scale forest research plot at Ngel Nyaki Forest Reserve on the Mambilla Plateau in Taraba State. The Ngel Nyaki plot will be the first CTFS-ForestGEO plot in Nigeria and only the fifth in the entire African continent.


The University of Canterbury NMFP, directed by Associate Professor Hazel Chapman, operates a teaching and research facility located on the edge of Ngel Nyaki forest, a hotspot of natural diversity. The NMFP works with Taraba State Forestry to protect the forest.

The field station, which has been operating for eight years, serves as a research laboratory and teaching center, with accommodation for scientists and students. Masters and PhD level students from Nigerian universities and institutions, as well as University of Canterbury students, undertake research within the reserve.
Associate Professor Chapman says the research is assisting conservation in Nigeria in critical ways.“The focus of the research carried out by the NMFP is aimed towards the conservation, restoration and management of these unique forests and understanding the services provided by the plants and animals in them. It is vitally important research, because Nigeria has already lost most of its primary forests and therefore the potential to benefit from them.”

Current research projects include understanding pollination networks, seed dispersal by primates and rats, and investigations into the medicinal properties of forest trees.

Field assistants have been trained from nearby Yelwa village to support the research effort by setting up and monitoring experiments. They receive training in using computers, data entry, photography, and telemetry techniques, providing transferable skills making them sought after employees on the Plateau.

Assoc. Prof. Chapman says, “In funding our research plot T.Y. Danjuma has given Taraba State and the NMFP a huge boost; it is a truly exciting development. The plot will attract more Nigerian and international researchers and students, it will provide work for more of the local community, and it will strengthen conservation initiatives. Data from the plot will contribute towards understanding the effects of climate change, carbon sequestration and forest fragmentation.”
