 
Weather data
A large number of automatic weather stations has been implemented in the frame of the BIOTA AFRICA project by the Namibian National Botanical Research Institute (NBRI) and the Group "Biodiversity, Evolution and Ecology" (BEE) of the University of Hamburg. The website offers hourly updates of data and graphs of a large number of weather parameters.

| Dataset metadata |
| Description | Soil seed bank data from highly degraded and non-degraded rangelands in arid southern Namibia, i.e. BIOTA Observatories Gellap-Ost and Nabaos. Data on seed bank properties (species composition, seed densities), vertical and horizontal patterning, direct germination methods. Seed/diaspore traits (weight, length, width) of the 35 most common seed bank species from location. |
| Purpose |
Assessment of below-ground land degradation and regeneration capacity towards improved vegetation states. |
