AgroForestree databaseSome of the major objectives of setting up this database are

To collect and present in a readily accessible format the relevant information on woody perennials (which are essential components of agroforestry systems). This information is currently scarce and scattered over a vast amount of literature.

To provide the information that tree users (farmers, landscapers, conservation groups etc) would rely on to make informed decisions whenever they integrate agroforestry trees in their activities

These major objectives would promote the better use of trees in Agroforestry systems

Theme and data modelThe AgroForestree database is a tree reference and selection guide

-Use of pre-defined parameters to retrieve the trees desired

-Keywords

-Geographic distribution

-Functional uses and /or service roles

-Free text (open) search

-Look up data on a tree you are interested in

-Botanic name

-Local /Common name

Data Model

• The next version of the database will incorporate an embedded spatial analysis tool. This will give users a new opportunity to predict the trees they can grow by making a spatial selection on a map as the following slides show

Tree Seed Suppliers Directory (TSSD)

• Sources of seeds and microsymbionts information of potential seed and microsymbiont

suppliers informed use of tree germplasm wider use of quality germplasm biosafety issues covers over 8000 taxa and 132 suppliers Information collected from suppliers questionnaire

Botanic Nomenclature for AF trees

• compilation of botanical names• its aim is to provide consistent scientific

naming of plants• prompted by misspelling emerging in

agroforestry literature • structure: current name, family, authority,

synonyms and common names • Sources: IK, Mabberley
