On this page are listed publications of the Cycad Specialist Group (CSG), as well as other cycad-related publications of interest.

CSG Publications

The most important CSG publication released to date is the Cycad Action Plan. Published in 2003, this 86-page document brings together a collection of data and opinions on one of the world's most threatened plant groups and presents a series of action plans to promote their conservation. The Cycad Action Plan is available in PDF format from the IUCN/SSC website. The full citation for this document is as follows:

Also in 2003, the CSG provided most of the data and analysis for the CITES Significant Trade Review of Cycads, compiled by TRAFFIC East/Southern Africa. The report is as follows:

• CSG 2003 Cycad Trade Review

The following news release on cycads was issued by the IUCN in 2003:

The following is a report submitted by the CSG Chair, Dr. John Donaldson, to the IUCN in 2004:

• CSG 2004 Report to IUCN

The following document consists of two articles written by CSG Chair, Dr. John Donaldson, for the Dec. 2004 Supplement of the Cycad Newsletter (quarterly publication of The Cycad Society: www.cycad.org). The first article is on CITES and cycad conservation, while the second explores whether or not trade in seeds might benefit cycad conservation.

Taxonomy

In 2002, a Cycad Classification Concepts workshop was held at Montgomery Botanical Center in Miami, FL, USA. The primary goal of the workshop was to ensure that cycad taxonomy and classification efforts are scientifically robust and standardized as much as possible. A 300-page volume entitled Cycad Classification: Concepts and Recommendations was published in 2004 from papers presented at this workshop. The full citation for this volume is as follows:

Walters, T. & R. Osborne (eds.). 2004. Cycad Classification: Concepts and Recommendations. CABI Publishing, Cambridge, MA.

Below is an emended description of Dioon mejiae presented at the CYCAD 2005 conference in Xalapa, Veracruz, Mexico.

The following is an illustrated poster and identification key summarizing the vegetative traits that are most useful in identifying the known species of Dioon. It was presented at the CYCAD 2005 conference in Xalapa, Veracruz, Mexico, and is available for sale from the Cycad Society.

The following is a similar illustrated poster and identification key summarizing the vegetative traits that are most useful in identifying the known species of Ceratozamia. It was presented at the CYCAD 2008 conference in Panama City, Panama, and is also available for sale from the Cycad Society.

Population Viability Assessments & Management Plans

On 17-21 July 2006, a population and habitat viability assessment (PHVA) workshop was held for Encephalartos latifrons in Bathurst, Eastern Cape, South Africa. The workshop was organized in association with the IUCN/SSC Conservation Breeding Specialist Group and the Endangered Wildlife Trust. Below is the report produced following this workshop:

Ethnobotany

The following is a preliminary assessment of the impacts of harvest on the Indian endemic, Cycas circinalis, in the Nilgiri Biosphere Reserve in Western Ghats, South India. It was prepared in a collaborative effort by representatives of People and Plants International and Keystone Foundation:

• Harvest, Trade, and Conservation of the Endemic Multi-use Cycad, Cycas circinalis L., in the Nilgiri Biosphere Reserve, South India. (600 Kb)

And below is a Cycad Newsletter article written by the same authors and describing their continuing work on Cycas circinalis in India:
