The Agroforestry Species Switchboard
The Agroforestry Species Switchboard is a “one-stop-shop” to retrieve data about a particular plant species across a wide range of information sources. Its particular objective is to provide information that supports research on trees and tree-based development activities such as agroforestry planting and wider restoration initiatives. Version 1.3 of the Switchboard documents the presence of a total of 26,301 plant species (34,066 species including synonyms) across 23 web-based information sources. When available, hyperlinks to selected species in particular information sources are provided. In total, Version 1.3 of the switchboard provides 221,984 hyperlinks at species level. The Switchboard also provides links to check on the correct spelling of particular species, and on synonyms and current names (see more below). Within ICRAF, the Switchboard cross-links our various databases by establishing a centralised naming system. A list and brief description of the 23 associated information sources that can be accessed through the Switchboard is given below (in order of listing in the Switchboard).
ICRAF databases, with links to individual species
- Agroforestree Database (http://www.worldagroforestry.org/output/agroforestree-database). This database provides information on the management, use and ecology of over 600 tree species which can be used in agroforestry systems globally. It is a good starting point for understanding more about many cultivated trees in smallholders’ farms.
- Tree Seed Suppliers Directory (http://www.worldagroforestry.org/output/tree-seed-suppliers-directory). This directory provides the most extensive available compiled information on global suppliers of seed and microsymbionts for over 5,000 tree and shrub species.
- African Wood Density Database (http://worldagroforestry.org/treesnmarkets/wood/data.php?id=1). This database provides air-dry wood density data for over 900 indigenous and exotic tree species found in Africa. It was developed in parallel with the Global Wood Density Database (see below).
- RELMA-ICRAF Useful Trees (http://www.worldagroforestry.org/usefultrees/index.php). These species-based factsheets provide information on the useful trees and shrubs of Eritrea, Ethiopia, Kenya, Tanzania, Uganda and Zambia, assembled as part of a series of Regional Land Management Unit (RELMA)-ICRAF publications. Information on ecology, uses, propagation, management, local names and botanical names is included.
- Tree Functional Attributes and Ecological Database (http://db.worldagroforestry.org). This database provides information on the properties and attributes of trees, usually at species level. It includes information on geographic distributions, ecological requirements, growth rates, uses and product value chains.
- Useful Tree Species for Africa Map (produced with the University of Copenhagen [Forest and Landscape Denmark]; http://www.worldagroforestry.org/output/useful-tree-species-africa). This interactive vegetation map tool enables the selection of useful tree species for planting at given locations anywhere in Africa using Google Earth for visualisation purposes. The Switchboard indicates which species are listed in this tool.
- vegetationmap4africa (produced with the University of Copenhagen; http://www.vegetationmap4africa.org/). This map tool shows the distribution of 1,022 plant species across Burundi, Ethiopia, Kenya, Uganda, Rwanda, Tanzania and Zambia using Google Earth, based on a high resolution potential natural vegetation map of eastern and southern Africa. It can be used to help select tree species for planting at given locations in mapped countries.
- Genetic Resources Unit Database (http://www.worldagroforestry.org/products/grunew/index.php/seeds/searchbyname). This database indicates accessions of trees and shrubs that are conserved and/or supplied for research purposes by ICRAF’s Genetic Resources Unit.

Which species are included in the Switchboard?
The list of species in the Agroforestry Species Switchboard is all those listed in the 23 main information sources indicated above. The Switchboard is therefore not restricted to woody tree and shrub species, despite these taxa being ICRAF’s primary interest. Subspecies, varieties and crosses between species have been excluded, as has information provided only at the genus level.
Detailed information on species notation
Species are listed in the Agroforestry Species Switchboard according to their currently accepted botanical name. To ensure this, we revised given species names for spelling errors and against synonyms as described in a selection of ICRAF databases. Where differences in spellings were noted in the compilation of version 1.0 of the Switchboard we used those spellings implemented by Tropicos (see above). Where differences between current names and synonyms were noted (for example, when different current names were listed), notations were checked against The Plant List (see above). The current name with the highest confidence level (http://www.theplantlist.org/about/#confidence) was then adopted (if the confidence level was the same for two current names, the original name was kept in the switchboard). When adding links to new databases for later versions of the Switchboard, we first checked spellings and current species names with the Taxonomic Name Resolution Service (TNRS; http://tnrs.iplantcollaborative.org/TNRSapp.html). Where differences were noted between current names according to TNRS and those indicated in version 1.0 of the Switchboard, we resolved using The Plant List.
Please be aware that the spelling and status (current or synonym) of names in the Agroforestry Species Switchboard have not been systematically rechecked for all plant species. It is possible that for some species synonyms are listed separately from current names. We encourage users to recheck the current status of a species against The Plant List, Tropicos or TNRS.
Development of the switchboard was made possible thanks to support from the CGIAR Research Program on Forests, Trees and Agroforestry (FTA; supported by the CGIAR Fund Donors)
