• Perspectives
Background
• Present state of vegetation data in West Africa– limited availability– lack of regional exchange– low degree of digitization
• Urgent need of such data in times of rapid environmental change
Objectives
• enhance digitization and improve data security
• increase availability and visibility of vegetation data for West Africa
• facilitate exchange and regional analyses
• identify data gaps and avoid redundant work
Projects / Partners
• BIOTA (Biodiversity Transect Analysis in Africa) and
SUN (Sustainable Use of Natural Vegetation in West Africa)
– Development and Coordination:Senckenberg Research Institute
– Universities of Ouagadougou, Cotonou, Niamey, Dakar, Abidjan, Bobo-Dioulasso, Aarhus and Frankfurt, Biodiversity and Climate Research Centre
Database Features
• Various kinds of relevés– species inventories– phytosociological relevés– dendrometrical relevés
Database Features
• Local offline database VegDa 3.0– local Access db allows editing in working environments
without internet connection– synchronisation with online database
Database Features
• Access Rights Management– each relevé can be declared „private“, „public“ or „shared
with selected users“
Database Features
• Search and export data– metadata visible for all relevés (including „private“ data)– comfortable data clipboard– various export options (local db, crosstables for community
analyses, species occurrence files for GIS and ENM programs)
Data Holdings

Perspectives
• finish last tests and launch final version soon!

Perspectives
• establish a comprehensive suite of botanical resources for West Africa
further db modules, e.g.- functional traits- plant use
www.westafricanplants.senckenberg.de
Perspectives
• regional analyses of biogeography, biodiversity and phytosociology
• studies on climate / land use change impact on food plants, pastures, ESS
• integration in global vegetation databases
