BOTANIC NOMENCLATURE FOR AGROFORESTRY TREES TREE DATABASES Compilation of the taxonomic status of agroforestry species Muasya S, Simons AJ, Salim AS and Kindt R The Botanic Nomenclature for Agroforestry Trees Database is a compilation of the taxonomic status of over 8000 woody and herbaceous taxa found in agroforest ecosystems. The database was prompted by the multiplicity of (mis)spellings and synonyms emerging in agroforestry literature, and the need for consistency. Currently there exists specialized volumes (e.g. Index Kewensis) for checking species identities but these are available to only a small fraction of scientists and others working in agroforestry. There are several advantages of getting names right. It enables you to search electronic sources of information (bibliographies, electronic abstracts and internet) for available literature. It also enables you to communicate with others about species in that alternative (synonyms) can be highlighted, and you can be confident that you are each talking about the same plant. As a standard we have used Index Kewensis and where necessary employed Mabberley’s (1997) Plant Book as a back up reference. In choosing between alternate forms of Latin spellings we have used William Stearn’s (1992) Botanic Latin as a guide. The Tree Domestication Programme of the World Agroforestry Centre has developed a number of databases to promote the better use of trees in agroforestry systems. The Agroforestree Database provides information on the management, use and ecology of a wide range of tree species which can be used in agroforestry systems. The Tree Seed Suppliers Directory lists suppliers of seed and microsymbionts for over 5900 tree species. The Botanic Nomenclature Database provides information on the correct taxonomy of trees, including synonyms and common names of over 8000 species. The three databases are linked with common formats. AGROFORESTREE DATABASE A tree species reference and selection guide TREE SEED SUPPLIERS DIRECTORY Sources of seeds and microsymbionts R Kindt and AS Salim with S Muasya, J Kimotho, A Waruhiu and A Mutua Salim AS, Simons AJ, Orwa C, Chege J, Owuor B and Mutua A The Agroforestree (AFT) Database is a species reference and selection guide for agroforestry trees. The main objective of the database is to provide detailed information on a number of species to field workers and researchers who are engaged in activities involving trees suitable for agroforestry systems and technologies. It is designed to help make rational decisions regarding the choice of candidate species for defined purposes. Information for each species covers species identity, ecology and distribution, propagation and management, functional uses, pests and diseases and a bibliography. To date more than 500 species have been included. The specific aims of the database are to: Enable quick and efficient access to a consolidated pool of information on tree species that can assume useful production and/or service functions; Provide a tool that will assist with the selection of species for use in agroforestry and related research using defined search criteria; Help researchers assess potential agroforestry trees for uses other than those commonly known; Provide indicators for the economic assessment of species through yield information on tree products. The production of the Tree Seed Suppliers Directory is framed within the aims of ICRAF’s Domestication of Agroforestry Trees Programme, which is concerned with increasing productivity and diversity of land use systems through the domestication of agroforestry trees. This directory is intended to: Contribute to the informed use of tree germplasm, which is an essential component of sustainable forestry and agroforestry practices Promote wider use of quality germplasm. Quality has both a genetic and a physiological component, and both are described in the directory. Quality descriptors can be used as criteria to select suppliers, and this will ensure that both the users and the suppliers recognize seed quality requirements The directory also highlights the importance of biosafety issues, and it presents biosafety information that suppliers have provided. Although the directory focuses on tree taxa of importance in the tropics, it lists some temperate taxa as well. It does not discriminate between taxa used for agroforestry and forestry purposes.
