What's New?
New feature: Expeditions! Interactive maps using Google Earth software trace collecting expeditions made by BDG Program resident collectors, complete with stories from the field, photo galleries, and full lists of plants collected. Currently, full expedition information is available for two collectors: Lynn Gillespie and Karen Redden.

Georeferencing Plants of the Guiana Shield: US Types. Type specimens in the U.S. National Herbarium from the Guiana Shield region have been georeferenced and a Google Map display and Google Earth placemarks are provided. A discussion of the methodology for determining coordinates for older specimens is presented.
The “Field Checklist of the Birds of Guyana, 2nd Edition.” (Braun, M.J, D.W. Finch, M.B. Robbins and B.K. Schmidt. 2007) was published. It contains 814 bird species that have been documented as occurring in Guyana. It is aimed at a general audience and is set up for bird watchers to be able to check off the species that they see.
The “Checklist of the Plants of the Guiana Shield” (Funk, V., T. Hollowell, P. Berry, C. Kelloff, and S.N. Alexander, 2007) covers all vascular plants known to occur in the Guiana Shield region of northeastern South America. It is the product of the combined efforts of two research initiatives, the Smithsonian Institution’s Biological Diversity of the Guiana Shield Program (BDG) and Missouri Botanical Garden’s Flora of the Venezuelan Guayana.
The BDG and Dr. Pat Herendeen, currently at the Chicago Botanic Garden (NSF grant) co-sponsored Dr. Karen Redden as a post-doctoral fellow to work on the Leguminosae collections from the Guiana Shield and to organize, participate in, and analyze results from collecting expeditions to the Guiana Shield. This year (2007) she spent three weeks as a resident collector in Guyana, and also made a collection trip to French Guiana. On these trips she made about 935 botanical collections, most with silica collected leaves for DNA work.
From January to April of 2007, Dr. Karen Redden made an expedition to Warashema and the Meamu Mountains in the Middle Mazaruni region of Guyana, accompanied by C. Perry, P. Benjamin, and D. Singh. The Meamu Mountain area is a fascinating amalgam of tepuis and lowland rainforest, and both mountains and the creeks leading to the mountains had never before been explored. The team collected over 600 plant specimens, including at least three newly identified species, one new hybrid, and numerous species that had never before been collected in the surrounding areas. This area also has a very diverse fauna; they observed two jaguars, a cock-of-the-rock lekking ground with over 40 birds, tapir, peccary, 3 species of monkeys, anacondas, and numerous other birds, reptiles, mammals and fishes.

Cristián Samper, Director of the National Museum of Natural History, and Hans Sues, Associate Director for Research and Collections, traveled to Guyana with Vicki Funk and Carol Kelloff in February 2007 to look at field sites and review the progress of the Biological Diversity of the Guiana Shield Program.

The University of Guyana is using students interested in biodiversity studies to work in the CSBD collections to help process and curate under the supervision of the Scientific Officers. This work/study program is helping the students lean more about the field of museum collections and has provided CSBD with a workforce. The CSBD has also begun a monthly biodiversity seminar, under the direction of Calvin Barnard. This seminar is open to staff, students, and the public.
